Description

SYSTEMS OF ASSORTMENT OF FRAGRANCE This application claims priority under the title , United States Code 119 (c) according to provisional application Serial No. 60 / 024,117, filed on August 19, 1996.

FIELD OF THE INVENTION The present invention relates to fragrance delivery systems suitable for use in personal care and personal hygiene articles, colognes, lotions, laundry detergent compositions, and hard surface cleaning compositions. The fragrance delivery systems comprise one or more pro-harmony molecules, each molecule capable of releasing one or more fragrance raw materials. Additionally, each pro-harmony is capable of releasing a different harmony (mixtures of fragrance raw materials) if it is used in a different type of composition (for example, laundry detergent versus deodorant with dial applicator).

BACKGROUND OF THE INVENTION Humans have applied essences and fragrances to their skin since ancient times and have used fragrances and essences to expand the aesthetic quality of their environment among others, clothing and domestic space. Originally these aesthetically pleasing materials were commonly isolated in crude forms, such as resins, gums or essential oils from natural sources, among others, barks, roots, leaves and fruits of indigenous plants. These resins, gums and oils were applied directly to the body or diluted with water or another solvent, including in some cases, wine. With the advent of modern chemistry, the individual components responsible for the odor properties of these resins, gums and oils were isolated and subsequently characterized. In addition to the common "perfume vehicles", among others, fine perfumes, colognes, cologne waters, aftershave lotions, and a wide variety of personal care and hygiene items, fragrances and scents are also released on clothing during the washing procedure. It is well known that mixtures of fragrance raw materials or perfumes deposited on a surface lose intensity and can change their character over time, mainly due to factors such as differential evaporation and surface penetration. Many attempts have been made to minimize these drawbacks, but without notable success. Particularly, efforts have been made to prolong the diffusion, as well as to improve other characteristics of the fragrance materials, for example by increasing the concentration of fragrance raw materials or by the use of additives such as silicones, glycerol, polyethylene glycols and the like. . These additions, however, have not been adequate to increase the longevity of the scent of the fragrance. Accordingly, there remains a need in the art for a fragrance delivery system that can be formulated into any type of product used to release an aesthetically pleasing fragrance, inter alia, in personal care and hygiene products, and in detergent compositions. for laundry, including additives for rinsing and drying. Additionally, the fragrance released must have a sustained perception, consequently, the fragrance must be released slowly.

BRIEF DESCRIPTION OF THE INVENTION The present invention covers the aforementioned needs inasmuch as it has been surprisingly discovered that a mixture of perfume or fragrance raw materials (harmonies) can be released from a pro-harmony precursor molecule, and that those pro-harmonies can serve as a system of fragrance supply in which a variety of fragrance mixtures are released depending on. the structure and design of the pro-armonia molecule. These pro-harmonies provide sustained retention of fragrance and perfume when applied to human skin, either directly or through an article for personal care or personal hygiene, such items for personal care and hygiene include, among others, deodorants, lotions or creams for the body, ointments, balms, ointments, antiseptics, tanning lotions, or shampoos. Additionally, the pro-harmonies of the present invention can be released onto the fabrics so that after the wash cycle has ended, the prorbanezes release the fragrance raw materials. The proto-harmonies described herein comprise fragrances in the form of stable and releasable "pro-fragrance". Additionally, the formulator can design compounds according to the present invention which can release different fragrance raw materials depending on the conditions of use. The pro-harmonies can be formulated in any product to be supplied, directly or indirectly, to human skin, clothing, or hard surfaces in which an aesthetically pleasing essence is desired. Once in contact with human skin, fabric or a surface, the pro-harmony becomes a primary fragrance mix at a rate that provides extended fragrance benefits. The fragrance delivery systems of the present invention may be a mixture of any number of pro-harmonies and may cover any desired fragrance or volatility "characteristic". The first aspect of the present invention relates to compositions that are applied to skin, fabrics, or hard surfaces, said compositions having increased fragrance retention and fragrance longevity. The appropriate compositions of the present invention are among other deodorants, body lotions or creams, suntan lotions, shampoos, granular and liquid laundry detergent compositions, fabric softeners for adding to rinse or dry, and hard surface cleaners, comprising one or more pro-armonia compounds with the formula: wherein R is an alkoxy derived from an alcohol fragrance raw material; R1, R2 and R3 are each independently hydrogen, substituted or unsubstituted linear alkyl of 1 to 30 carbon atoms, unsubstituted or substituted branched alkyl of 3 to 30 carbon atoms, substituted or unsubstituted cyclic alkyl of 3 to 30 carbon atoms carbon, substituted or unsubstituted linear alkenyl of 2 to 30 carbon atoms, branched or unsubstituted branched alkenyl of 3 to 30 carbon atoms, substituted or unsubstituted cyclic alkenyl of 3 to 30 carbon atoms, linear alkynyl substituted or unsubstituted substituted from 2 to 30 carbon atoms, unsubstituted or substituted branched alkynyl of 3 to 30 carbon atoms, substituted or unsubstituted aryl of 6 to 30 carbon atoms, substituted or unsubstituted alkylene of 2 to 20 carbon atoms, alkylenoxyalkyl substituted or unsubstituted of 3 to 20 carbon atoms, substituted or unsubstituted alkylenearyl of 7 to 20 carbon atoms, substituted or unsubstituted alkylenenoxy of 6 to 20 carbon atoms e carbon and mixtures thereof; provided that at least one of Rl, R2, R3 is a unit with the formula: wherein R4, R5 and R6 are each independently hydrogen, substituted or unsubstituted linear alkyl of 1 to 30 carbon atoms, substituted or unsubstituted branched alkyl of 3 to 30 carbon atomsunsubstituted or substituted cyclic alkyl of 3 to 30 carbon atoms, linear substituted or unsubstituted alkoxy of 1 to 30 carbon atoms, branched or unsubstituted branched alkoxy of 3 to 30 carbon atoms, substituted or unsubstituted cyclic alkoxy of 3 to 30 carbon atoms, unsubstituted or substituted linear alkenyl of 2 to 30 carbon atoms, branched or unsubstituted branched alkenyl of 3 to 30 carbon atoms, substituted or unsubstituted cyclic alkenyl of 3 to 30 carbon atoms, alkynyl linear substituted or unsubstituted of 2 to 30 carbon atoms, branched or unsubstituted substituted alkynyl of 3 to 30 carbon atoms, substituted or unsubstituted alkylenearyl of 6 to 30 carbon atoms, substituted or unsubstituted aryl of 6 to 30 carbon atoms of carbon, or R4, R5 and R6 can be taken together to form substituted or unsubstituted aryl of 6 to 30 carbon atoms; and mixtures thereof. The compositions of the present invention comprise at least about 0.01%, preferably from about 0.01% to 15%, more preferably from about 1% to 5%, much more preferably from about 0.01% to 1% by weight, of one or more of the β-ketoesters described herein. The present invention also relates to the use of the fragrance delivery system of the present invention to release fragrance harmonies when pro-harmonies are applied to a site if the pro-harmonies are released by a vehicle or carrier. The vehicle or carrier may be a liquid such as water, or an article containing a pro-harmony β-ketoester and is treated with an agent that catalyzes the release of the fragrance raw materials. These and other objects, features and advantages will become apparent to those skilled in the art from a reading of the following detailed description and the appended claims. All percentages, ratios and proportions indicated are by weight, unless otherwise specified. All temperatures are in degrees Celsius (° C) unless otherwise specified. All the documents cited, in their relevant part, are incorporated here by reference.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fragrance delivery system which deposits one or more "pro-harmony" fragrance compounds on the skin, hair, fabric, ceramic mosaic, linoleum, or other substrate during use or which may be applied to an article of manufacture in which pro-harmony is activated to release one or more fragrance raw materials. Because the pro-harmonies comprising the fragrance delivery system of the present invention generally have a higher molecular weight than non-combined fragrance raw materials and other "pro-fragrance type" compounds (ie, pro-fragrances that they only release a single equivalent of a fragrance raw material), these constitute a means for the effective delivery of two or more fragrance raw materials, which results in an improved longevity of the fragrance raw materials on the substrate.

Blends of fragrance materials are known to those skilled in the art of fragrances and perfumes as "harmonies." The term "harmony" as used herein, is defined as "a mixture of two or more ^ fragrance raw materials" which are Artistically combined to impart a pleasant fragrance, smell, scent, or characteristic. " For the purposes of the present invention, "fragrance raw materials" are defined herein as compounds that impart an odor, fragrance, scent, or aroma either alone or in combination with other "fragrance raw materials" that are considered aesthetically pleasing, preferably said compounds have a molecular weight of at least 100 g / mol. For the purposes of the present invention the term "pro-fragrance" is defined as "a β-ketoester that releases an alcohol of fragrance raw material" while a "pro-harmony" is defined as a "β-ketoester which liberates two or more fragrance raw materials ". For the purposes of the present invention, however, since a material that is "pro-fragrance" in one embodiment, can serve as "pro-harmony" in a different embodiment, the term "pro-fragrance" is used interchangeably with the term "pro-armonia" and each term can be used to equally indicate pro-fragrance molecules of ñ-ketoester, pro-harmony molecules of ß-ketoester, or both collectively. Typically the "fragrance raw materials" comprise among other alcohols, ketones, aldehydes, esters, ethers, nitriles, and cyclic alkenes and acyclics, especially terpenes. A list of common "fragrance raw materials" can be found in various reference sources, for example, "Perfume and Flavor Chemicals", Vols. I and II; Steffen Arclander Allured Pub. Co. (1994) and "Perfumes: Art, Science and Technology" Müller, P. M. and Lamparsky, D., Blackie Academic and Professional (1994) both incorporated herein by reference. As an example, but not by way of limitation, the fragrance harmonies released by the pro-harmonies of the present invention have "spirit", "character" or "note", which are described among others, such as rose, jasmine, lilac, Field lily, violet, orange, peach, watermelon, and lemon, or pro-harmony can release fragrance raw materials that provide a "fresh" or "clean" note, for example, linalool or dihydro ircenol. The harmony may be "modified" or "combined" in addition by the inclusion of pro-fragrances that provide acute or intermediate modifier notes which, as an additional benefit provided by the present invention, may be incorporated into the pro-harmony. For example, a "rose essence" can be combined with a "green" modifier to "change the character of the fragrance harmony". For the purposes of the present invention, only fragrance raw materials with a molecular weight of at least 100 g / mol are considered "preferred fragrance raw materials" according to the present invention. Therefore, low molecular weight materials among other methanol, ethanol, methyl acetate, ethyl acetate, and methyl formate, which are common components of the fragrance harmonies, are less preferred fragrance raw materials. However, the formulator may wish to release these materials of lower molecular weight (less than 100 g / mol molecular weight) as carriers, astringents, diluents, balancers, fixatives, or as other suitable additive materials. For the purposes of the present invention, the "sharp note" fragrance raw materials are defined as "fragrances having a high vapor pressure, and when applied to a paper pad, the vaporization takes place in 2 hours, and no scent residue; essentially, the initial impression of the perfume formulation is provided by sharp notes ".

For the purposes of the present invention, the "intermediate note" fragrance raw materials are defined as "fragrances having an average vapor pressure, and when applied to a paper pad, the aroma remains from about 2 hours until about 6 hours, essentially, the intermediate notes provide the support of the perfume formulation ". For the purposes of the present invention, the "grave note" fragrance raw materials are defined as "fragrances having a low vapor pressure and high retention, and when applied to a paper pad, the aroma remains for more than 6 hours, essentially, the serious notes provide the characteristic of the perfume formulation, the terms "acute note", "intermediate note" and "Grade note" are well known to those skilled in the art of compositions containing fragrances. However, the reference to a specific fragrance raw material as "sharp note" in the present invention means that other experts in the techniques of fragrance-containing compositions may not categorize the same ingredient as an "intermediate note". The same applies to fragrance raw materials referred to as "intermediate notes" and "serious notes".

Surprisingly, the pro-harmonies comprising the fragrance delivery systems of the present invention are capable of releasing at least one fragrance raw material, preferably the pro-harmonies release two or more fragrance raw materials. For example, the 3-7-dimethyl-l, 6-octadien-3-yl 3- (ß-naphthyl) -3-oxo-propionate proarmony, having the formula: frees, depending on the conditions of use, at least two fragrance raw materials including linalool, ß-naphthylmethyl ketone, myrcene, a-terpinolene, and A-3-carene. The pro-harmonies comprising the fragrance delivery systems of the present invention are capable of releasing their fragrance compounds by more than a single chemical mechanism, a point that is key to the variety of fragrance raw materials that are released from a only composed pro-harmony. Accordingly, depending on the wishes of the formulator, the pro-harmonies of the present invention are capable of releasing a different mixture of fragrance raw materials depending on the release of the release medium. For example, the 3- (ß-naphtenyl) -3-oxo-propionate 3,7-dimethyl-l, 6-octadien-3-yl proarmony produces a different harmony when the release of fragrance raw material is experienced in water , that when said pro-harmony is subjected to the high temperature typical of an automatic clothes dryer or an iron. Typically the pro-harmonies of the present invention release a mixture of alcohols, esters, ketones, hydrocarbon materials, especially terpenes, with aesthetically pleasing qualities, and mixtures thereof. For the purposes of the present invention, the term "hydrocarbyl material" is defined as a compound that essentially comprises only carbon and hydrogen among other alkanes, alkenes, and alkynes, whether linear, cyclic, branched, - combinations thereof. An example of a hydrocarbyl material that is capable of being released by a pro-harmony of the present invention is mircene. For the purposes of the present invention the term "terpene" is used to designate hydrocarbons among others myrcene, thymonene and Ot-terpinene. However, experts in both the perfume technique and organic chemistry recognize that geraniol and nerol which are included in the list of "fragrance raw material alcohols" above, are also terpenes. Throughout the present specification the term "terpene" is used interchangeably with "hydrocarbyl" and when "terpene" is used widely, it refers to all alcohols, ketones, alkenes, etc., which are generally considered terpenes, and when the term "terpene" is used in a strict sense, it refers primarily to alkanes, alkenes, etc., which typically have 10 carbon atoms (terpenes) or 15 carbon atoms (sesquiterpenes). The formulator can, however, adjust the conditions of use so that the simple fragrance raw materials are released by the pro-harmony. For example, a β-ketoester pro-fragrance prepared from dihydromyrcenol and capable of releasing dihydromyrcenol as well as other fragrance raw materials can be formulated in a composition that allows only the release of dihydromyrcenol until the conditions of use are changed or adjusted in such a way that the other fragrance raw materials can be supplied. Additionally, the pro-harmonies can be prepared in such a way that they release different fragrance raw materials under different conditions. For example, while a garment is drying, a harmony of fragrance is released, and a second harmony of fragrance is released when the garment is dry and hung in a closet. Examples of alcohols releasable by the pro-harmonies are those described above and are typically the fragrance raw material alcohols used to form the predecessor compounds. However, during the fragrance raw material release process, the fragrance raw material alcohols are capable of undergoing further modifications, including isomerization and / or rearrangement. Consequently, in addition to the original alcohol used to form the predecessor pro-harmony ester, the additional alcohols can be formed by transformations that occur during the release process. Depending on the selections that the formulator makes when designing the pro-harmony molecules in the formulation of a fragrance delivery system according to the present invention, these transformations can take place to a greater or lesser degree. Non-limiting examples of releasable terpenes by the pro-harmonies of the present invention include the hydrocarbyl materials myrcene, ocimene, β-farnesene, cis-alkylene, trans-alkylene, carvomentene, limonene, terpinene, gamma-terpinene, terpinolene, a -frenlandrene, β-phellandrene, 2-carene, 3-carene, α-pinene, β-pinene, camphene, and other terpenes, for example, (-) - (2S, 4R) -2- (2-methyl-1) - propenyl) -4-methyltetrahydropyran (cis-rose oxide), (-) - (2S, 4S) -2- (2- (2-methyl-1-propenyl) -4-methyltetrahydropyran (trans-rose oxide) , 2-methyl-2-vinyl-5- (OE-hydroxyisopropyl) tetrahydrofuran (linalool oxide), and mixtures thereof.

In accordance with the present invention all the isomers of a fragrance raw material either in the form of the harmony or the fragrance raw material liberated, are suitable for use in the present invention. When optical isomers are possible, the fragrance raw materials may be included as the separate chemical isomer or as the combined racemic mixture. For example, 3,7-dimethyl-6-octen-1-ol, commonly known to those skilled in the art as β-citronlol or cefrole, comprises a pair of optical isomers, R- (+) - β-citronellol and S - (-) - ß-citronellol. Each of these materials separately or as a racemic pair are suitable for use as fragrance raw materials in the present invention. However, those skilled in the art of fragrances, by using the present invention, should not neglect the olfactory differences that individual optical isomers, mixtures of optical isomers or mixtures of positional isomers impart. By way of example, carvone, 2-methyl-5- (1-methyletenyl) -2-cyclohexene-1-one, exists as 2 isomers: d-carvone and 1-carvone. The d-carvone is found in caraway oil and emits a fragrance completely different from 1-carvone, which is found in the oil of peppermint. According to the present invention, a pro-harmony releasing d-carvone will result in an essence or fragrance different from one that liberates 1-carvone. The same applies for 1-carvona. In addition, the isomers, such as the cis / trans isomers, for example, nerol (3,7-dimethyl-cis-2,6-octadien-1-ol) and geraniol (3,7-dimethyl-trans-2,6- octadien-l-ol), are well known to those skilled in the art of perfumery, and these two terpene alcohols, which are commonly presented as mixtures, have different fragrance characteristics. Consequently, when formulating fragrance raw materials containing mixtures of isomers such as nerol / geraniol, the formulator must also take into account that different sources of raw material have different proportions of isomers. An example of a preferred pro-harmony is 3- (7-dimethyl-l, 6-octadien-3-yl 3- (β-naphthyl) -3-oxo-propionate with the formula: which releases at least the alcohol raw material of fragrance linalool, which has the formula: and the ketone raw material of fragrance, methylnaphthyl ketone, with the formula: A further example of a preferred pro-harmony includes 2,6-dimethyl-7-octen-2-yl 3- (4-methoxyphenyl) -3-oxo-propionate, having the formula: which releases at least the alcohol of fragrance raw material, dihydromyrcenol, with the formula: and the ketone raw material of fragrance, methyl-4-methoxyphenyl ketone, which has the formula: Further non-limiting examples of preferred pro-harmonies include 3,7-dimethyl-l, 6-octadien-3-yl 3- (a-naphthyl) -3-oxo-propionate acetate, ((1-naphthol) acetate of linalyl), which has the formula: 3- (4-methoxyphenyl) -3-oxo-propionate of 2,6-dimethyl-7-octen-2-yl, (3- (4-methoxyphenyl) -3-oxo-proponic acid dihydromyrcenyl ester, which has the formula: 3- (4-Nitrophenyl) -3-oxo-prop-onate of 2,6-dimethyl-7-octen-2-yl, (3- (4-nitrophenyl) -3-oxo-propionic acid dihydromircenyl ester, with the formula: 3- (2,6-Dimethyl-7-octen-2-yl 3- (ß-naphthyl) -3-oxo-propionate, dihydromyrcenyl ((2-naphthoyl) -acetate) having the formula: (3- (4-methoxyphenyl) -3-oxo-propionate of 3, 7-dimethyl-l, 6-octadien-3-yl, (3- (4-methoxyphenyl) -3-oxo-proponic acid linalyl ester ), of the formula: 3- (β-Naphthyl) -3-oxo-propionate of (α, α-4-trimethyl-3-cyclohexenyl) methyl, ((2-naphthoyl) a-terpinyl acetate), with the formula: 3-ß-naphthyl-3-oxopropionate of 9-decen-1-yl, (9-decen-1-yl) (2-naphthoyl) acetate, alternatively known as rosalva 2'-acetonaphthone, with the formula: 3,7-dimethyl-l, 6-octadien-3-yl, 3- (nonanyl) -3-oxoproponate, ((nonanoyl) linalyl acetate), alternatively known as octyl- ((linalyl) α-acetyl) ketone, with the formula: Additional non-limiting examples of preferred fragrances comprising the fragrance delivery systems of the present invention include cis-3-hexen-1-yl 3- (ß-naphthyl) -3-oxo-propionate, 3- (nonanil) -2,6-dimethyl-7-octen-2-yl-3-oxo-propionate, 3-oxo-butyrate 2, 6-dimethyl-7-octen-2-yl, 3,7-dimethyl-1,6-octadien-3-yl, 3- (ß-naphthyl) -3-oxo-2-3-oxo-butyrate methylpropionate 2, 6-dimethyl-7-octen-2-yl, 3- (ß-naphthyl) -3-oxo-2,2-dimethylpropionate of 3,7-dimethyl-l, 6-octadien-3-yl, 3- (3,7-dimethyl-l, 6-octadien-3-yl, 3- (β-naphthyl) -3-oxo-propionate of 3,7-dimethyl- 3-oxo-2-methylpropionate 2,6-octadienyl, 3-heptyl-3-oxo-propionate of 3,7-dimethyl-2,6-octadienyl, and mixtures thereof. Without the desire to be limited by theory, the process by which the pro-harmonies of the present invention release their fragrance raw materials is not limited to a single trajectory. In fact, the same molecule, under identical conditions, can have different equivalent trajectories by which the same or different compounds are released. For example, both the nerol and the geraniol can be released from an ester formed only by geraniol, if the conditions under which the transformation of geraniol to nerol can occur, are present during use. These conditions can be built into the molecule by the formulator, or they can be provided by the surrounding medium (eg, the formulation). Additionally, during the process of releasing fragrance raw materials, both the ketone portion and the alcohol portion of the pro-harmonies are capable of carrying out chemical transformations that provide a blend of fragrance notes not subject to inclusion in the products. original harmonies. For example, a pro-harmony ester containing the alcohol raw material of fragrance citronellol, can potentially release a mixture of rose oxides according to the following scheme: provided that adequate conditions of rearrangement are present during use. The formulator is not limited to the supply of a type of fragrance, for example a fragrance raw material of acute, intermediate or severe note. Instead, a mix of high notes, a mix of high and low notes, or any combination of high, low, or high notes can be released in any suitable ratio. As described above, those skilled in the art of preparing fragrance-containing compositions have categorized the fragrances into three types based on their relative volatility: acute, intermediate and severe notes. Additionally, fragrances are categorized by the odor they produce: some of these description terms (descriptors) are broad and others relatively specific. For example "floral" is a term that connotes smells associated with flowers, while the term "lilac" is more specific. The descriptors used by those skilled in the art of perfumes and fragrances are among others "rose", "floral", "green", "citrus", "spices", "honey" and "moss". The sources of these notes are not limited to a chemical class; alcohols can produce essences of "rose", "green" and "moss", while "rose" essences may contain alcohols, ketones, terpenes, aldehydes, etc. Acute, intermediate and severe notes can serve different purposes in the fragrance mix and when formulated properly, produce a "balanced fragrance" composition. Based on volatility, these notes are described by those skilled in the art in the following manner: serious notes have the longest aroma duration; the intermediate notes have a medium volatility; and the high notes are the most volatile.

The compositions described below, as well as others chosen by the formulator, comprise a fragrance delivery system utilizing the pro-harmonies of the present invention to successfully release a "balanced fragrance" profile. It is also recognized by those skilled in the art that descriptors that refer to aesthetic perceptions as "acute", "intermediate" and "serious" notes are relative terms. A fragrance raw material characterized as a sharp note by a formulator usually has the same classification among many other perfumers. The same is true for intermediate and serious grades, however, occasionally a formulator can classify a given fragrance raw material as an intermediate note instead of a sharp note, or vice versa, but this fact does not diminish the usefulness of a given compound or his absolute identity. Acute, intermediate and serious notes are now combined reproducibly to produce perfumes, colognes, aftershave lotions, cologne waters, etc. for application on the skin, which have unique and pleasant odor characteristics. However, in addition to this pleasant fragrance, a fragrance delivery system that is used to release an essence to a perfume, cologne, personal care item, laundry detergent composition or hard surface cleaner, must fill a number of technical requirements. . It must be strong enough, it must be persistent, and it must retain its "essential character" during its period of evaporation. Apart from the changes made to the proharmony molecules in order to modify the fragrance profiles provided by the fragrance delivery systems of the present invention, modifications of these pro-harmonies can be made for the purpose of increasing the substantivity of the materials. The formulator by selecting a suitable unit Rl, R2 or R3, or by selection of R4, R5 and R6, can influence the degree and proportion at which the pro-harmony is deposited on the fabric or other surface. Those skilled in the art of formulating detergent compositions will recognize that the terms "substantive" and "substantivity" refer to the propensity of a compound to adhere to, associate with, or deposit on a surface, preferably the surface of the fabric. Therefore, more substantive compounds adhere more easily to the surface of the fabric. However, the substantive compounds, in general, do not react with the surface on which they are deposited. An example of a pro-harmony that is modified to provide greater substantivity with the fabric is 3- (ß-naphthyl) -) -2- (methoxypentaethyleneoxy) -3-oxo-propionate from 2,6-dimethyl-7-octen-2-yl (dihydromyrcenyl ((2-naphthoyl) (2-E5-methoxy) acetate), of the formula: In addition to the substitution at the β-carbon atom, substitution can be made at other sites in the pro-harmony molecule, for example, 3- (methoxytriethylaxy) -3-oxo-butyrate of 3,7-dimethyl-1, 6. -octadien-3-yl, (methoxy E3) linalyl acetate of the formula: is a modified pro-harmony to increase the substantivity in cloth. The pro-Armenians of the present invention are useful in articles of personal care and hygiene, including among other creams and lotions, make-up, tanning lotions, balms, ointments, depilatory agents, all of which may also contain one or more ingredients pharmaceutically assets; hair care items, such as shampoos and hair mops and sprays; Laundry detergent compositions including heavy duty liquids and granules, light duty liquids, laundry bars, pastes and gels; hard surface cleaning compositions. The pro-harmonies of the present invention are also suitable for use in fine fragrances, colognes, cologne waters, aftershave lotions and the like, wherein the slow release of the fragrance raw material is important.

The formulator is not limited by the present invention to supplying the pro-harmonies of the present invention by means of a carrier article, that is, by means of compositions for laundry, hand cream, lotions, etc. The pro-harmonies of the present invention are suitable for providing a durable fragrance or mixture of fragrances to articles including paper or paper-type materials. Examples of these include sanitary napkins, diapers, paper towels, items for incontinence mediation, and the like. The formulator may formulate a fragrance delivery system that contains pro-harmonies that are stable, that is, do not begin to decompose until they are put into operation by a "catalyst". The catalyst, depending on the structure of the pro-harmony, can add humidity, a relative change in pH, or an increase in temperature. For example, if water alone is a suitable catalyst to initiate the release of fragrance raw materials from a harmony, a paper towel that has been impregnated with the pro-harmonies can be moistened and then used to release the fragrance in one place. Additionally, the formulator may use the fragrance delivery system of the present invention as a means to indicate that a condition exists. For example, a specific liquid can be stored or transported in a cardboard, container or container, which can be prone to damage or slow leakage. The package or other packaging of the package can be impregnated with the fragrance delivery system of the present invention and upon contact of the liquid material with the pro-harmonies then release a fragrance raw material with a low intensity unpleasant odor that alerts the user about the adulteration that the package or container has suffered. The following are non-limiting examples of compositions in which the pro-harmonies of the present invention are suitable for use.

If a high level of foam is desired, soaps of 10 to 16 carbon atoms of branched chain can be used. Especially useful are mixtures of anionic and nonionic surfactants. Other useful conventional surfactants are described below and are described in ordinary texts. The anionic surfactants can be broadly described as water-soluble salts, particularly the alkali metal salts, of organic-sulfur reaction products having in their molecular structure an alkyl radical containing from about 8 to 22 carbon atoms and a radical selected from the group consisting of sulphonic acid ester and sulfuric acid radicals. (The alkyl portion of the higher acyl radicals is included in the term alkyl). Important examples of the anionic synthetic detergents which can form the surfactant component of the compositions of the present invention are sodium or potassium alkyl sulfates, especially those obtained by sulfation of higher alcohols (8 to 18 carbon atoms) produced by reduction of tallow glycerides or coconut oil; sodium or potassium alkylbenzenesulfonates, in which the alkyl group contains about 9 to about 15 carbon atoms, (the alkyl radical can be a straight or branched aliphatic chain); sodium alkyl glyceryl ether sulfonates, especially those ethers of higher alcohols derived from tallow and coconut oil; sulphates and sodium sulfonates monoglycerides of coconut oil fatty acids; sodium or potassium salts or sulfuric acid ester resulting from the reaction of one mole of a higher fatty alcohol (for example tallow or coconut alcohols) and about 1 to 10 moles of ethylene oxide; sodium or potassium salts of alkylphenol ethylene oxide ether sulfates with about 1 to 10 ethylene oxide units per molecule and in which the alkyl radicals contain from 8 to 12 carbon atoms; the reaction products of fatty acids are derivatives of sodium or potassium salts of coconut oil of fatty acid amides of a methyl tauride in which the fatty acids, for example, are coconut oil and beta-acetoxy or beta- sodium or potassium acetamido-anesulfonates where aican has 8 to 22 carbon atoms. Additionally, the secondary alkyl sulphates can be used by the formulator alone or in combination with other surfactant materials and the following identifies and illustrates the differences between sulphated surfactants and otherwise conventional alkyl sulfate surfactants. The following are non-limiting examples of these ingredients: Conventional primary alkyl sulfates (AS), as illustrated above, have the general formula ROS03-M + wherein R is typically a linear hydrocarbyl group of 8 to 22 carbon atoms and M is a water-soluble cation. Branched chain primary alkyl sulfate surfactants (ie, branched chain "PAS") having 8 to 22 carbon atoms are also known; see, for example, European Patent Application 439,316, Smith and co-inventors, filed January 21, 1991. Conventional secondary alkyl sulfate surfactants are those materials that have the sulfate portion distributed randomly along the structure Main hydrocarbyl of the molecule. These materials can be represented by the structure CH. (CH:) r. (CH0S03-Mr) (CH2)? R.CH3 where m and n are integers of 2 or more and the sum of m + n is typically close to 9 to 17, and M is a water soluble cation. The above-mentioned secondary alkyl sulfates are those prepared by the addition of H2SO4 to the olefins. A typical synthesis using alpha-olefins and sulfuric acid is discussed in US Pat. No. 3,234,258, Morris, issued February 8, 1966 or in US Pat. No. 5,075,041, Lutz, issued December 24, 1991.

It can be used as raw materials, corn syrup with high dextrose content, corn syrup with high fructose content, and corn syrup with high maltose content as well as the individual sugars mentioned above. These corn syrups can produce a mixture of sugar components for Q. It should be understood that this in no way is intended to exclude other suitable raw materials. Q is more preferably selected from the group consisting of -CH2 (CH0H) pCH20H.CH (CH: 0H) (CHOH) n-lCH20H. -CH2 (CHOH) 2-CHOR ') (CHOH) CH2OH, and alkoxylated derivatives thereof, wherein n is an integer from 3 to 5, inclusive, and R' is hydrogen or a cyclic or aliphatic monosaccharide.

ADDITIVE INGREDIENTS FOR LAUNDRY The following are non-limiting examples of additive ingredients useful in laundry compositions of the present invention, said additive ingredients include builders, optical brighteners, whiteness enhancers, bleach catalysts, bleach activators, soil release polymers, transfer agents dyes, dispersants, enzymes, foam suppressants, dyes, perfumes, dyes, inert salts, hydrotropes, enzymes, photoactivators, fluorescent agents, fabric conditioners, hydrolyzable surfactants, preservatives, antioxidants, chelators, stabilizers, anticaking agents, anti-aging agents wrinkles, germicides, fungicides, anti-corrosive agents and mixtures thereof. Detergency builders - Builders may optionally be included in the compositions herein to assist in the control of mineral hardness. Both inorganic and organic improvers can be used. Builders are typically used in laundry detergent compositions to aid in the removal of particulate grime. The level of builder can vary widely depending on the final use of the composition and its desired physical form. When present, the compositions will typically contain from about 5% to about 50%, more typically about 5% to 30%, by weight, of detergency builder. Granulated formulations typically contain from about 10% to 80%, more typically about 15% to 50% by weight, of builder. However, this does not mean that the highest or lowest levels of detergency builder are excluded. Inorganic or phosphorus-containing builders include, but are not limited to, alkali metals, ammonium and alkanolammonium salts of polyphosphates (exemplified by tripolyphosphates, pyrophosphates, and vitreous polymeric metaphosphates), phosphonates, phytic acid, silicates, carbonates (including bicarbonates and sesquicarbonates), sulfates and aluminosilicates. However, phosphate-free builders are required in some places. It is important to note that the compositions herein work surprisingly well even in the presence of so-called "weak" builders (when compared to phosphates) as citrate, or in the so-called "improver-improver" situation which can occur with zeolite or layered silicate builders. Examples of silicate builders are alkali metal silicates, particularly those having a SiO2: Na2O ratio in the 1.6: 1 to 3.2: 1 scale and layered silicates, such as the layered sodium silicates described in US Patent 4,664,839. issued on May 12, 1987 to HP Rieck. NaSKS-6 is the trade name of a crystalline layered silicate marketed by Hoechst (commonly abbreviated here as "SKS-6"). Unlike zeolite builders, the Na SKS-6 silicate builder does not contain aluminum. The NaSKS-6 has the form of stratified silicate with delta-Na? SiOs morphology. It can be prepared by methods such as those described in German patents DE-A-3, 417, 649 and DE-A-3, 742, 043. SKS-6 is a highly preferred layered silicate for use herein, but others of these layered silicates, such as those having the general formula NaMSix02x + l-yH20 wherein M is sodium or hydrogen, x is a number from 1.9 to 4, preferably 2, e and is a number from 0 to 20, preferably 0, can be used in the present. Other diverse layered silicates from Hoechst include NaSKS-5. NaSKS-11, in alpha, beta and gamma forms. As indicated above, delta-Na2Si05 (NaSKS-6 form) is most preferred for use herein. Other silicates may also be useful, such as, for example, magnesium silicate, which may serve as an agent in the granular formulations, as a stabilizing agent in oxygen bleaches, and as a component of foam control systems. Examples of carbonate builders are the alkali metal and alkaline earth metal carbonates, such as those discussed in German patent application 2,321,001 published on November 15, 1973. Aluminosilicate builders are useful in the present invention. Aluminosilicate builders are of great importance in heavy duty commercially available granular detergent compositions, and can also be a significant detergency builder ingredient in liquid detergent formulations. The aluminosilicate builders include those that have the empirical formula: [Mz (zA102) and] .xH20 where z and e are integers of at least 6, the molar ratio of zay is on the scale of 1.0 to about 0.5, and x is an integer of about 15 to about 264. Useful aluminosilicate ion exchange materials are available commercially These aluminosilicates can be of crystalline or amorphous structure and can be aluminosilicates present in nature or synthetically derived. A method for producing aluminosilicate ion exchange materials is discussed in US Pat. No. 3,985,669, to Krummel and co-inventors, issued October 12, 1976. Preferred crystalline aluminosilicate ion exchange synthetic materials useful herein, are available under the designations Zeolite A, Zeolite P (B), Zeolite MAP and Zeolite X. In an especially preferred embodiment, the crystalline aluminosilicate ion exchange material has the formula: Nai2 [(A102) 12 (Si02) 12)] -xH20 where x is from about 20 to about 30. especially around 27. This material is known as Zeolite A. Dehydrated zeolites (x = 0-10) can also be used. Preferably, the aluminosilicate has a particle size of about 0.1-10 microns in diameter. Organic builders suitable for the purposes of the present invention include, but are not limited to, a wide variety of polycarboxylate compounds. As used herein, "polycarboxylate" refers to compounds with a plurality of carboxylate groups, preferably at least 3 carboxylates. The polycarboxylate builder generally can be added in the form of a neutralized salt. When used in salt form, alkali metal salts, such as sodium, potassium and lithium, or alkanolammonium salts, are preferred. Included among polycarboxylate builders is a variety of useful material categories. An important category of polycarboxylate builders comprises the ether polycarboxylates, including oxydisuccinate, as discussed in Berg patent US 3,128,287, issued April 7, 1964, and Lamberti patent US 3,635,830 and co-inventors, issued January 18. 1972. See also the "TMS / TDS" detergency builders of US Pat. No. 4,663,071, issued to Bush and co-inventors, on May 5, 1987. Suitable ether polycarboxylates also include cyclic compounds, particularly alicyclic compounds, such as those described in US Pat. US Patent 3,923,679; 3,835,163; 4,158,635; 4,120,874 and 4,102,903. Other useful builders include ether hydroxypolycarboxylates, maleic anhydride copolymers with ethylene or methyl vinyl ether, 1,3,5-trihydroxybenzene -2, 4,6-trisulfonic acid, and carboxymethyloxysuccinic acid, the various alkali metal salts, ammonium salts and of substituted ammonium of polyacetic acids such as ethylenediaminetetraacetic acid and nitrilotriacetic acid, also polycarboxylates such as mellitic acid, oxydisuccinic acid, polymaleic acid, benzene-1,3,5-tricarboxylic acid, carboxymethyloxysuccinic acid, and soluble salts thereof. Citrate builders, for example, citric acid and soluble salts thereof (particularly sodium salt), are polycarboxylate builders of particular importance for heavy duty liquid detergent formulations because of their availability from renewable resources and their biodegradability. Citrates can also be used in granular compositions, especially in combination with zeolite and / or layered silicate builders. Oxydisuccinates are also especially useful in these compositions and combinations. Also suitable in the detergent compositions of the present invention are the 3,3-dicarboxy-4-oxa-1, 6-hexanedioates and the related compounds discussed in Bush's US Patent 4,566,984, issued January 28, 1986. The improvers of useful succinic acid detergency include the alkyl- and alkenyl-succinic acids of 5 to 20 carbon atoms and the salts thereof. A particularly preferred compound of this type is dodecenylsuccinic acid. Specific examples of succinate builders include: iauryl succinate, myristylsuccinate, palmityl succinate, 2-dodecenylsuccinate (the preferred one), 2-pentadecenylsuccinate, and the like. Iauryl succinates are the preferred builders of this group, and are described in European patent application 86200690.5 / 0200263, published on November 5, 1986. Other suitable polycarboxylates are discussed in US Patent 4,144,226, Crutchfield and co-inventors , issued March 13, 1979 and US Pat. No. 3,308,067, Diehl, issued March 7, 1967. See also US Pat. No. 3,723,322 to Diehl. Fatty acids, for example monocarboxylic acids of 12 to 18 carbon atoms, can also be incorporated into the compositions alone or in combination with the aforementioned detergency builders, especially the citrate and / or succinate builders, to provide additional enhancing activity. This use of fatty acids will generally result in a decrease in the foam, which should be taken into account by the formulator. In situations where phosphorus-based builders can be used, and especially in the formulation of bars used for hand-washing operations, the various alkali metal phosphates can be used as well-known sodium tripolyphosphates, pyrophosphate and sodium orthophosphate. . Phosphonate builders such as 1,1-diphosphonate of 1-hydroxetane and other known phosphonates can also be used (see, for example, US Patents 3,159,581; 3,213,030; 3,422,021; 3,400,148 and 3,422,137). Other Ingredients - A wide variety of other ingredients useful in detergent compositions can be included in the compositions herein, including other active ingredients, carriers, hydrotropes, processing aids, dyes or pigments, solid fillers for stick compositions, etc. Other optional ingredients include enzymes, bleaches, bleach activators, bleach catalysts, photoactivators, dyes, fluorescers, fabric conditioners, hydrolyzable surfactants, optical brighteners, preservatives, antioxidants, chelators, stabilizers, aqueous washing liquid, where its detergent function. To illustrate this technique in more detail, a porous hydrophobic silica (trademark SIPERNAT DIO, DeGUSSA) is mixed with a proteolytic enzyme solution containing 3 - 5% nonionic surfactant of ethoxylated alcohol of 13 to 15 carbon atoms (SO 7). Typically, the enzyme / surfactant solution is 2.5 times the weight of the silica. The resulting powder is dispersed with stirring in silicone oil (various viscosities of silicone oil can be used in the range of 500-12,500). The resulting dispersion in silicone oil is emulsified or otherwise added to the final detergent matrix. By these means, ingredients such as the aforementioned enzymes, bleaches, whiteness activators, whiteness catalysts, photoactivators, dyes, fluorescers, cloth conditioners or hydrolyzable surfactants can be "protected" for use in detergent compositions. The detergent compositions herein will preferably be formulated such that, during use in cleaning operations in aqueous medium, the wash water will have a pH of about 6.5 to 11, preferably about 7.5 and 10.5 Laundry products typically have a pH of 9-11. Techniques for controlling pH at recommended use levels include the use of regulators, alkalis, acids, etc., and are well known to those skilled in the art. The following are non-limiting examples of fragrance delivery system and the pro-harmonies comprising said system.

The slow release of the fragrance raw material provides a prolonged sensation of "freshness". The hard surface cleaners of the present invention may be in any form, inter alia, liquid, semi-solid, gelatinous, or solid. The cleaner can be a scrubbing cleaner and therefore contain an abrasive material. The hard surface cleaning compositions according to the present invention having increased perfume retention, as well as high surface gloss and low scratch, comprise: a) at least about 0.1%, preferably at least 0.5% by weight, of a sulfosuccinamate with the formula: wherein R1 and R2 are hydrogen or -S03M2 if R1 is equal to R2; R3 is butyl when R4 is ethyl and R3 is pentyl when R4 is propyl; M and M2 are independently hydrogen or a cation forming salt; b) at least about 0.1%, preferably at least 0.5% by weight, of a nonionic surfactant having the formula CH3 (CH2) xCH20 (CH2CH20) yH where x is from around 6 to about 12, and is around 3.5 to about 10; c) at least about 0.01%, preferably from about 0.01% to 15%, more preferably from about 0.1% to 10%, much preferable from about 0.2% to 1% by weight, of one or more 68 anti-shrinking agents, anti-wrinkle agents, soil release agents, germicides, fungicides, dispersants and anti-corrosion agents. If high foam production is desired, foam reinforcers such as alkanolamides of 10 to 16 carbon atoms can be incorporated into the compositions, typically at levels of 1% -10%. The monoethanol- and diethanolamides illustrate a typical class of these foam boosters. The use of these foam reinforcers with high foam producing additive surfactants, such as the amines, amines, betaines and sultaines mentioned above, is also advantageous. If desired, the soluble magnesium salts such as MgC12, MgSO4, and the like, can be added at levels of, typically, 0.1% -2% to provide additional foam and improve the performance of fat removal. Various detergent ingredients employed in the present compositions can be further stabilized by absorbing said ingredients in a porous hydrophobic substrate, then covering said substrate with a hydrophobic layer. Preferably, the detergent ingredient is mixed with a surfactant before being absorbed by the porous substrate. In use, the detergent ingredient is released from the substrate in harmonies according to the present invention; and d) the remainder, carriers and additive ingredients, said additive ingredients selected from the group consisting of abrasives, detergency builders, bleaches, whiteness enhancers, clays, detergent surfactants, thickeners, dispersants, enzymes, pigments, dyes, filler salts, hydrotropes, enzymes, preservatives, antioxidants, chelators, stabilizers, germicides, fungicides, solvents, photo-disinfectants, and mixtures thereof.

CONDITIONING LOTION FOR SKIN An example of a skin care composition of the present invention comprises an ester with a total number of carbon atoms of more than about 28, for example lauryl laurate, lauryl myristate, iristyl myristate, behenyl caprylate, cetearyl palmitate, behenyl stearate, more preferable cetearyl palmitate and cetyl stearate. The present compositions in addition to the esters described above, contain an emollient material in an amount such that the amount of more emollient ester is about 0.2% to about 25% of the total composition, preferably about 4% to 18%. One function of the emollient is to ensure that the ester is sufficiently plasticized to allow it to take a film-like state on the skin. The emollient in the present compositions is selected from the group consisting of fatty alcohols, esters having less than about 24 carbon atoms in total (e.g., isopropyl palmitate), branched chain esters having more than about 24 atoms carbon (for example cetearyl octonate), squalane, liquid or solid paraffins, mixtures of fatty acids and squalane, mixtures of fatty acids and liquid or solid paraffins and mixtures thereof. The aforementioned esters, which have less than 24 carbon atoms or branched esters having more than 24 atoms, if used as emollients should preferably be used in an amount equal to about one third of the length of the ester chain. The particular emollient selected depends in part on the particular ester selected since the correct plasticization, as indicated above, is desired. The emollient for the esters having more than 28 carbon atoms is preferably selected from the group consisting of squalane, liquid or solid parafams and mixtures of fatty alcohols with squalane or parafams. The fatty alcohols and fatty acids typically useful in the present compositions include those having from 12 to 22 carbon atoms, such as cetyl alcohol, myristyl alcohol, stearyl alcohol, stearic acid and palmitic acid. Paraffins include, for example, mineral oil, petrolatum and paraffin wax. The use of distilled water in the present compositions is preferred.

(e) Polyalkylenes such as hydrogenated polyisobutene and polyethylene; and (f) Sterols such as cholesterol and phytosterol. These optional oily phase materials may comprise up to about 80% of the oily phase, preferably up to about 35%. When used at these levels, the optional components do not impair the occlusive nature of the compositions and increase the overall cosmetic function of the composition.

AQUEOUS PHASE COMPONENTS The aqueous phase of the compositions may contain many different materials, including: (a) Humectants, such as sorbitol, glycerin, propylene glycol, alkoxylated glucose and hexanetriol at a level of about 1% a (b) Thickening agents, such as carboxyvinyl polymers, ethylcellulose, polyvinyl alcohol, carboxymethylcellulose, vegetable gums and clays such as Veegum MR, (magnesium aluminum silicate, RT Vanderbilt, Inc.) at a level of about 0.01% to 6%; (c) Proteins and polypeptides at a level of about 0.1% to 3%; (d) Preservatives such as methyl, ethyl, propyl and butyl esters of hydroxybenzoic acid (Paraben-Mallinckrodt Chemical Corporation) EDTA and imidazolidinyl urea (Germall 115-Sutton Laboratories) at a level of about 0.2% to 2.5%; and (e) An alkaline agent such as sodium hydroxide to neutralize, if desired, part of the fatty acids or thickeners that may be present. All percentages of these additional aqueous phase components are with respect to the total composition. The present compositions may also contain agents suitable for aesthetic purposes such as dyes. The compositions of the present invention are preferably substantially free of materials that adversely affect their performance. Accordingly, some ingredients, such as polyethylene glycols are preferably present only at levels below about 1% of the total composition. The pH of the present compositions is preferably in the approximate range of 7.5-10.

THE METHOD OF PREPARATION The compositions of the present invention generally have a lotion consistency and may be in the form of oil-in-water or water-in-oil emulsions; the first being the preferred one due to its more pleasant cosmetic properties. The compositions of the present invention are preferably made by the method comprising the steps of: a) Preparing the oily phase; b) Prepare the aqueous phase; and c) Add the oily phase to the aqueous phase. Step (a) is carried out by heating the aqueous phase materials to a temperature approximately equal to that of the oily phase. The emulsion is formed by slowly adding the oily phase prepared in step (a) to the aqueous phase prepared in step (b) with mixing.

The pro-harmonies comprising the fragrance delivery system or other ingredients may be added to the phase in which they are soluble before mixing the two phases or they may be added directly to the mixed aqueous and oily phases. In addition to compositions containing fragrances for use on human skin, the pro-accords of the present invention are also suitable for use in any application for odor control or fragrance mediation. An example of this odor control capability are waste pickers, odor control items useful for covering cages, mangers, and other domestic animal housing areas.

For example, US 5,339,769 to Toth and co-inventors, issued August 23, 1994, describes a process for making an absorbent composition in which the pro-harmony materials of the present invention can be well accommodated. An example of suitable material for collecting waste comprising the pro-harmonies of the present invention can be formed by the following process. A Glatt fluid bed granulator is loaded with 1,0000 g of bentonite clay (90% of particles greater than 420 microns) and 10 g of a cellulosic ether (Methocel ™ K15M Premium, a cellulose ether having a viscosity of 15,000 centipoise (cps) as a 2% aqueous solution). The granulator is turned on and the temperature of the product is brought to about 40 ° C (exit temperature). When the outlet temperature reaches around 40 ° C, atomized water is sprayed on the moving powders inside the granulator. During the granulation process, the inlet air temperature is maintained from 70 ° C to 80 ° C; the air atomization pressure is 1.96-2.46 kg / cm2; and the spray cycle is 45 seconds with a stirring time of 15 seconds. The clay agglomerates / cellulose ether swell over time. The water hydrates the cellulosic ether polymer which produces adhesion to form the granule.

At this time, it is more advantageous to introduce pro-harmony materials and other aesthetic fragrances. The granule formation promotes the aggregation of the small particles of the inert substrate, for example, clay particles of about 50 to 600 microns. The formation of a granule significantly reduces the quality of the powder in the final product while the waste collector forms an agglomerate when it is moistened. In an alternative mode of the clay-based waste collection box with mixed items / proharmony, once the clay particles have been formed, a concentrated solution, or an alcohol-based carrier mixture of the pro-harmonies can be released to the surface of the granule by convenient means. A stick deodorant gel of the present invention containing the composition given below, and which is essentially free of water, is prepared as follows: TABLE V% by weight Ingredients 30 31 32 Dipropylene glycol 39.85 51.95 75.10 Sodium Stearate 5.50 5.50 5.50 1.

All the above materials, except the pro-harmony fragrance, are mixed vigorously and heated to about 121 ° C until the mixture is clear. The mixture is then cooled to about 80 ° C and the proharmony is added by stirring. The mixture is poured into bar molds and cooled to room temperature to form the stick deodorant compositions of the present invention. A personal cleansing composition is prepared by combining the following ingredients using conventional blending techniques.
