Description

COMPOSITIONS FOR LAUNDRY THAT HAVE SMELL REDUCED SMELL. AND METHODS TO PROVIDE THE SAME FIELD OF THE INVENTION The present invention relates to detergent compositions for laundry, fabric softeners and fabric appearance that have a reduced malodor and methods for providing such compositions. The reduced malodor compositions of the present invention comprise an effective amount of a co-pro-fragrance material that effectively masks the degradation products typical of fabric softening actives.

BACKGROUND OF THE INVENTION Laundry detergent compositions and fabric softeners comprise active ingredients, inter alia, surfactants, diester quaternary ammonium compounds and diamide all of which are derived from fatty acids. Fatty acids and materials made from fatty acid sources, especially those that have one or more sites of unsaturation, degrade over time due to the effects of oxygen, as well as other factors. In fact, the degradation of fatty acids is attributed to the "rotten" or "rancid" odor associated with lard, vegetable oils, etc. that are no longer considered adequate for human consumption. Laundry detergent compositions and fabric softeners, either added during rinsing or added to the substrate (i.e., drying sheets), also develop bad odors due to the degradation of materials comprising fatty acid portions. One proposed remedy has been the inclusion of perfumes and other raw fragrance materials in the compositions to mask the objectionable odor. For a material to be effective as a perfume or fragrance it must be volatile enough to be "smelled". However, it is because of the high volatility of the perfume ingredients that the laundry detergent compositions and the softening compositions become incapable of masking aromas just before malodour formation occurs later in the shelf life of the product. In addition, fabric softening compositions are typically acidic (pH from 2.5 to 5.5), while laundry detergent compositions are alkaline (pH from 8 to about 11). Therefore, a perfume ingredient or masking agent that is effective on one pH scale may not be effective on another. In addition, the formulator should consider the synergy that the raw perfume materials and masking agents may have with other auxiliary ingredients that constitute the laundry or fabric conditioning compositions. Therefore, the fact that a material can serve as an effective odor masking and odor control agent in a fabric softening composition does not mean that the same material is effective in a laundry detergent composition. Accordingly, there remains a need in the art for compounds that mask bad odors and methods for masking these malodors that are formed in all types of laundry detergent and fabric softener compositions. In fact, the need for a method for releasing in a controllable manner a raw fragrance material or odor masking agent has been felt for a long time to provide the consumer with the confidence that a laundry detergent composition or fabric softener is still effective PREVIOUS TECHNIQUE The following documents refer to the matter of the fragrance ingredients.

BRIEF DESCRIPTION OF THE INVENTION The present invention satisfies the aforementioned needs because it has been surprisingly discovered that raw fragrance materials can serve to mask odor formation in laundry detergent compositions, fabric softening compositions and the like, and that these materials are available from a liberable and sustainable way by including certain co-profragancies in the formulation for laundry. The co-profragances act to slowly release raw fragrance materials that are sufficiently volatile to be aesthetically appreciated, while being strong enough to mask the bad odors that may form during certain conditions of storage and use. However, because there is a continuous release of raw fragrance materials over time by co-profragances, the pleasant aroma does not dissipate or evaporate in a manner similar to that of free perfumes and fragrance materials. In fact, the formulator, when applying the conditions described herein, can design co-profragrance molecules that will continue to release raw fragrance materials for varying lengths of time. Likewise, the raw fragrance materials releasable by the co-profragances of the present invention, can be any raw fragrance material convertible into a releasable co-profragance; among others, aldehydes, ketones, alcohols, terpenes and esters.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for providing laundry detergent compositions and fabric softeners of low or no odor, said method comprises the step of adding one or more profragrances or co-profragances to a laundry detergent or fabric softening composition. which are capable of releasing one or more raw fragrance materials during the lifetime of the laundry detergent composition or fabric softener. It is common that after the formulation the detergent compositions for laundry and fabric softeners slowly begin to form bad odors. While not wishing to be bound by theory, in many cases, especially under the circumstances in which fatty acids have been used as starting materials for preparing detersive surfactants, diester quaternary ammonium compounds (DEQA's) and other compounds based on triglycerides, these molecules containing fatty acyl units can begin to oxidize and / or hydrolyze under certain conditions of storage and use, especially under the liquid alkaline conditions of certain laundry detergent compositions and the typical acidic conditions of fabric softening formulations. This is especially true when fatty acyl units contain unsaturation sites. The fatty acids that are released by this degradation process can eventually include fatty acids that have a low odor threshold, as well as an unpleasant odor. This problem is overcome by mixing, in addition to any other perfume or desired fragrance raw material, one or more pro-fragrances or co-proforgances according to the present invention. Each co-profragance, depending on which raw fragrance materials comprise the co-profragance and the structure of co-profragance, will have a differential release rate and separate aroma or odor. The formulator, by judiciously assembling the co-propragance molecule itself, can provide a prolonged release of fragrance to a laundry detergent composition or fabric softener for several months beyond the product degradation time and thus prolong the life under storage of product composition. further, the formulation of co-profragancias of faster release with co-profragancias having a delayed or longer release can provide a product having a mixture of different aromas, as well as providing variable levels of fragrance released. For example, a product can be formulated to degrade so that initially low levels of raw fragrance materials are present, but at a time when the degradation of fatty acyl groups is more prone to form odors, levels are released. of higher fragrances. For some formulations a specific delayed release of a particular fragrance raw material may be used to indicate the end of shelf life or other variants of the product. Some co-profragances have been formulated for the supply of their raw fragrance materials after the profagance or co-profragancy has been effectively delivered to a cloth surface or, in some cases, to human skin or hair. However, the co-profragances of the present invention slowly release their raw perfume materials while the product is stored in the original container essentially in the original compositional form. This slow release extends the shelf life of fabric softening and laundry compositions. Typically, these products are stable for an extended period of time, in fact, beyond the time in which the first malodorous materials are formed. These malodorous compounds have a very low odor threshold, therefore, only a very small amount of material needs to be degraded into a malodorous material so that the unpleasant odor is perceptible by the consumer. Many consumers incorrectly associate a bad smell as a sign that the material is no longer "effective". The ability to inappropriately interpret that a laundry or fabric softener composition is "beyond useful life" due to malodorous materials is therefore surpassed by the present invention. The pro-fragrances and co-proforgances of the present invention begin to supply the raw fragrance materials in a slow and controlled manner once they are combined with the final formulation, or after its activation, for example, placed in a hold having a temperature above a critical temperature limit that facilitates the degradation of the ingredients that leads to the formation of a bad smell. For the purposes of the present invention, the term "profragance" is defined as "co-profragance which is designed to release a single fragrance material", while "co-profragance" is defined as "material that releases two or more materials. raw fragrance. " However, for the purposes of the present invention, because some fragrance releasing materials that serve as a "profragance" in one embodiment may also serve as a "co-profragancy" in a different embodiment, the term "profragrance" is used interchangeably with the term "co-profragance" and either of the two terms can be used to equally well define any fragrance release compound described herein individually or collectively. For the purposes of the present invention, "raw fragrance materials" are defined herein as compounds that impart an odor, fragrance, scent or aroma either alone or in combination with other "raw fragrance materials", which is considered aesthetically pleasing , preferably said compounds have a molecular weight of at least 100 g / mol. The compositions containing co-pro-fragrances of the present invention may comprise any number of co-profragances that when taken together are capable of releasing complex perfume fragrances. However, in some cases the fragrance release co-proforgances of the present invention are capable of undergoing chemical transformation and thereby releasing one or more raw fragrance materials in addition to the raw fragrance materials used to prepare the coconut. -profragance of origin. further, the pro-fragrances and co-profragances of the present invention are suitable for the supply of any type of fragrance "characteristic" desired by the formulator. The following describes the co-profragances and fragrance-releasing pro-fragrances of the present invention.

In addition to the releasable alcohols listed herein above under the β-ketoesters, the orthocarbonates according to the present invention are also cyclic orthocarbonates comprising at least one diol having the formula: wherein R8, R9, R10 and R11 are each independently hydrogen, linear or branched C1-C20 alkyl, linear or branched C1-C20 alkenyl , linear, branched or cyclic C-1-C20 alkylenecarboxy, linear or branched or cyclic C-j-C20 carboxyalkyl, linear or branched C-1-C20 alkyleneamino, linear or branched C-1-C20 alkyleneamino, linear C 1 -C 20 aminoalkyl or branched, linear, branched or cyclic C-1-C20 alkylenecarboxamido, linear or branched C 1 -C 20 carboxamidoalkyl, alkyleneoxy having the formula: R13 - (OCH2CH)? (CH2) and R12 wherein R12 is hydrogen or methyl; R 13 is hydrogen or C 1 -C 2 alkyl; n is from 0 to 4, x is from 1 to about 20, and is from 0 to about 20. In addition to the initial release of two equivalents of alcohol and one carbonate equivalent by the scheme illustrated in the above, the carbonate fragrances that are released by orthocarbonates can continue to hydrolyze and further liberate two equivalents of one or more alcohols of raw fragrance material according to the following scheme: O Rto-C-OR '1 R ^ OH + R1OH providing this up to four equivalents of alcohol of raw fragrance material per equivalent of orthocarbonate supplied. The carbonate propagancy which is liberated by the orthocarbonate can itself be a fragrance raw material in addition to being a pro-fragrance, preferably the carbonate that is released serves as a fragrance raw material. An orthocarbonate comprising four different fragrance raw materials will always release a carbonate which is a co-profragance (hydrolyzes to release a binary fragrance) in addition to any other additional fragrance properties attributable to the carbonate. Examples of alcohols appropriately released by the hydrolysis of the ortho ester co-proforgances are the same as those listed hereinabove under β-ketoesters. The most preferred orthocarbonate co-profragances of the present invention have each of the portions R1, R2, R3 and R4 obtained from an alcohol of fragrance raw material, whereby the preferred pro-fragrances have a molecular weight that is at least 4 times the molecular weight of the lower "fragrance raw material alcohol", which comprises orthocarban co-profragance. In addition, preferred orthocarbonate co-proforgances have a molecular weight that is greater than or equal to 350 g / mol. Non-limiting examples of the most preferred orthocarbonate coprograncies according to the present invention include: tetra-geranyl orthocarbonate, tetra-phenylethyl orthocarbonate, tetrakis (3-methyl-5-phenylpentyl) orthocarbonate, tetrakis orthocarbonate (c) / s-3-hexenyl), bis (geranyl) bis (c / s-3-hexenyl) orthocarbonate, bis (phenylethyl) bis (c / s-3-hexenyl) orthocarbonate, tetrakis (citronellyl) orthocarbonate, orthocarbonate tetrakis (linalyl), bis (linalyl) bis (geranyl) orthocarbonate, tetrakis orthocarbonate (mircenyl), tetrakis (cinnamyl) orthocarbonate. In accordance with the present invention, all isomers of a fragrance raw material, either in the form of profragance or in the form of fragrance raw material released, are suitable for use in the present invention. When optical isomers are possible, fragrance raw materials may be included, either as a separate chemical isomer or as a combined racemic mixture. For example, 3,7-dimethyl-6-octen-1-ol, commonly known to those skilled in the art as beta-citronellol or cefrole, includes a pair of optical isomers R - (+) - beta-citronellaI and S- (s -) - beta-citronellol. Each of these materials separately or as a racemic pair are suitable for use as a fragrance raw material in the present invention. However, those skilled in the art of fragrances, by use of the present invention, should not neglect the olfactory differences imparted by the individual optical isomers, mixtures of optical isomers or mixtures of positional isomers. As an example, carvone, 2-methyl-5- (1-methylethenyl) -2-cyclohexen-1-one exists as two isomers; d-carvona and 1-carvona. d-carvone is found in caraway oil and gives a completely different fragrance to l-carvone, which is found in the oil of yerbabuena. In accordance with the present invention, a pro-fragrance releasing d-carvone will result in a different fragrance or aroma than that which liberates l-carvone. The same applies to I-carvona. In addition, isomers such as cis / trans isomers, for example, nerol (3,7-dimethyl-c / s-2,6-octadien-1-ol) and geraniol (3,7-dimethyl-rans-2, 6-octadien-1-ol), are well known to those skilled in the perfumery technology and these two terpene alcohols, which commonly occur as a mixture, have different fragrance characteristics. Therefore, when formulating fragrance raw materials that include mixtures of isomers such as nerol / geraniol, the formulator must take into account whether different sources of raw material have different isomer ratios. The formulator is not limited to the release of a single type of fragrance, for example a high, medium, or base note of the fragrance raw material. Instead, a mixture of high notes, a mixture of central and high notes, or any combination of base, high, and central notes can be released in any appropriate ratio. As described above, those skilled in the art of preparing compositions containing fragrances, have cataloged the fragrances into three types based on their relative volatility; as high, central, and base notes. In addition, fragrances are classified by the smell they produce; some of these descriptors are broad and others are relatively specific. For example, "floral" is a term which refers to aromas associated with flowers while the term "lilac" is more specific. The descriptors used by those qualified in the technique of perfumes and fragrances are inter alia "pink", "floral", "green", "citrus", "spicy", "honey", and "musk". The sources of these notes are not limited to a single chemical class; alcohols can produce aromas of "rose", "green" and "musk", while "rose" aromas can include alcohols, ketones, terpenes, aldehydes, etc. The high, central and base notes each serve a different purpose in mixing the fragrances and when properly formulated they produce a "balanced fragrance". Based on volatility, these notes are described by those skilled in the art as: the base notes have the most lasting aroma; the central notes have an average volatility; and high notes are the most volatile. The compositions described herein below, as well as others chosen by the formulator, comprise a fragrance release system which utilizes the pro-fragrances of the invention herein to successfully leave a "balanced fragrance" profile. It is further recognized by those skilled in the art that descriptors that refer to aesthetic perceptions such as "high", "central" and "base" note are relative terms. A fragrance raw material classified as a high note by a formulator usually has the same classification among most perfume manufacturers. The same is true for core and base notes, however, occasionally a formulator may classify a raw material of a given fragrance as a central note rather than a high note, or vice versa, but this fact does not diminish the usefulness of a combined compound or its absolute identity. The top, center and base notes are now combined in a reproducible way to produce perfumes, colognes, aftershave lotions, toilet lotions, etc., to be applied to the skin, which have pleasant and unique smelling characteristics. However, apart from this pleasant fragrance, a fragrance release system which is used to leave a scent to a laundry detergent composition must meet a number of technical requirements. Must be strong enough, must be persistent, and must retain its "essential character" throughout its period of evaporation and release of fragrance raw material. The compositions of the present invention comprise at least an effective amount of one or more pro-fragrances or co-proforgances such as those described above in the present invention. What is meant in the present invention with "an effective amount" of a co-profragance or profragrance is defined as "at least about 0.01%, preferably from about 0.01% to 155, more preferred from about 0.1% to about 5%. %, more preferred still from about 0.1% to 1% by weight, of a co-profragance such as that described above in the present invention. " An example of a preferred co-profragance is 3,7-dimethyl-1,6-octadien-3-yl-3- (beta-naphthyl) -3-oxo-propionate having the formula: which releases at least the alcohol of fragrance raw material, linalool, which has the formula: and the fragrance raw material ketone, methylnaphthyl ketone, which has the formula: A further example of a co-profragance is tris (phenylethyl) orthoacetate which releases a binary fragrance having a "rose" characteristic comprising 2 parts of phenylethyl alcohol and 1 part of phenylethyl acetate in accordance with the following scheme : Phenylethyl acetate (phenylethyl) orthoacetate A further example of a co-profragance is di-citronellyl benzylacetate capable of releasing the binary citronellol / citronellyl acetate fragrance having a "rose" characteristic along with the modifiers of "jasmine" benzyl alcohol / benzyl acetate conformity with the following scheme: citronelol citronellyl acetate benzyl acetate benzyl bis (citronellyl) benzyl orthoacetate alcohol The formulator can therefore deliver a complex fragrance or fragrance to appropriately mask odors that may be formed from laundry detergent compositions or fabric softening compositions.

See WO 9,206,154. of sugar include the N-alkoxy polyhydric acid fatty acid amides, such as N (3-methoxypropyl) glucamide of C? o-C- | 8-The N-propyl- to N- hexylglucamides of C- | 2-Ci8 can be used for low foam formation. Conventional IC soaps Q-C20 can also be used. If high foaming is desired, branched chain C10-C16 soaps can be used. Mixtures of anionic and nonionic surfactants are especially useful. Other conventional useful surfactants are described hereinafter and are listed in standard texts. Anionic surfactants can be broadly described as water soluble salts, particularly the alkali metal salts, of organic reaction products with sulfuric acid having in its molecular structure an alkyl radical containing from 8 to 22 carbon atoms and a radical selected from the group consisting of sulfonic acid ester and acid radicals sulfuric. (Included in the term alkyl is the alkyl portion of higher acyl radicals). Important examples of synthetic anionic detergents which can form the surfactant component of the compositions of the present invention are the sodium or potassium alkyl sulfates, especially those obtained by sulfating the higher alcohols (Cs to CJ 8 carbon atoms) produced by the reduction of tallow glycerides or coconut oil; sodium or potassium alkylbenzenesulfonates, in which the alkyl group contains from about 9 to about 15 carbon atoms, (the alkyl radical can be a straight or branched aliphatic chain); the alkyl glyceryl sodium ether sulfonates, especially those ethers of higher alcohols derived from tallow and coconut oil; the sodium sulfates and sulphonates of the monoglycerides of the fatty acids of coconut oil; the sodium or potassium salts of the sulfuric acid ester of the reaction product of one mole of a higher fatty alcohol (e.g. tallow or coconut alcohols) and from 1 to 10 moles of ethylene oxide; the 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 the fatty acids are derivatives of the potassium and sodium salts of the coconut oil of the fatty acid amides of a methyl tauride in which the fatty acids, for example, are derived from coconut oil and beta acetoxy or beta acetamido alcansulfonates of sodium or potassium where the alkane has 8 to 22 carbon atoms. Additionally, the secondary alkyl sulphates can be used by the formulator exclusively or in conjunction with other surfactant materials and the following identifies and illustrates the differences between the sulfated surfactants and the otherwise conventional alkylsulfate surfactants. Non-limiting examples of such ingredients are as follows. The conventional primary alkyl sulfates (AS), such as those illustrated above, have the general formula ROSO3-M + wherein R is typically a C8-22 linear hydrocarbyl group and M is a water-solubilizing cation. Branched chain primary alkyl sulfate surfactants (e.g., branched chain "PAS") having 8 to 20 carbon atoms are also known; see, for example, European Patent Application 439,316, Smith et al., issued January 21, 1991. Conventional secondary alkyl sulfate surfactants are those materials which have the sulfate portion distributed randomly along the "base structure" of hydrocarbyl of the molecule. Such materials can be represented by the structure CH3 (CH2) n (CHOS? 3-M +) (CH2) mCH3 where m and n are integers of 2 or larger and the sum of m + n is typically about 9 to 17, and M is a cation solubilizing in water. The aforementioned secondary alkyl sulphates are those prepared by the addition of H2SO4 to the olefins. A typical synthesis using alpha-olefins and sulfuric acid is described in US Pat. No. 3,234,258, Morris, issued February 8, 1966 or in U.S. Patent No. 5,075,041, Lutz, issued December 24, 1991. See also US Patent 5,349,101, Lutz et al., Issued September 20, 1994.; Patent E.U.A- 5,389,277, Prieto, issued February 14, 1995.

TABLE I The formulator, depending on the desired physical and performance properties of the final fabric softening active, can choose any of the aforementioned sources of fatty acyl portions, or alternatively, the formulator can mix source of triglycerides to form a "made mixture". to measure". However, those skilled in the art of fats and oils will recognize that the fatty acyl composition may vary, such as in the case of vegetable oil, from harvest to harvest, or from variety of vegetable oil source to variety of oil source. vegetable. The DEQAs that are prepared using fatty acids obtained from natural sources are preferred.

Detergency builders Builders may optionally be included in the compositions herein to help control the hardness of minerals. Inorganic and organic builders can be used. Builders are typically used in fabric washing compositions to help remove particulate soils. 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 comprise at least about 1% builder. The formulations typically comprise from about 5% to about 50%, very typically from about 5% to about 30%, by weight builder. Granulated formulations typically comprise from about 10% to about 80%, very typically from about 15% to about 50% by weight of the builder. However, lower or higher detergency builder levels are not excluded. Inorganic or phosphorus-containing builders include, but are not limited to, alkali metal, ammonium and alkanolammonium salts of polyphosphates (illustrated by tripolyphosphates, pyrophosphates and vitreous polymeric metaphosphates), phosphonates, phytic acid, silicates, carbonates (including bicarbonates and sesquicarbonates), sulfates and aluminosilicates. However, non-phosphate builders are required in certain places. Importantly, the compositions herein work surprisingly well even in the presence of so-called "weak" detergency builders (as compared to phosphate builders) such as citrates, or in the so-called "lower detergency enhancement" situation that It can occur with zeolite builders or stratified silicate. Examples of silicate builders are alkali metal silicates, particularly those having a Si 2: Na 2 ratio. in the scale from 1.6: 1 to 3.2: 1 and layered silicates, such as the layered sodium silicates described in US Pat. No. 4,664,839, issued May 12, 1987 to H. P. Rieck. NaSKS-6 is the trade name for a crystalline layered silicate sold by Hoechst (commonly abbreviated as "SKS-6"). Unlike zeolite builders, the NaSKS-6 silicate builder does not contain aluminum. The NaSKS-6 has the morphological form delta-Na2Si? 5 of stratified silicate. It can be prepared by methods such as those described in German Application DE-A-3, 417,649 and DE-A-3,742,043. SKS-6 is a highly preferred stratified silicate for use herein, but other layered silicates, such as those having the general formula NaMSix? 2? +? VH2O wherein M is sodium or hydrogen, x is a number from 1.9 to 4, preferably 2, and y is a number from 0 to 20, preferably 0 can be used herein. Some other stratified silicates from Hoechst include NaSKS-5, NaSKS-7 and NaSKS-1 1 as the alpha, beta and gamma forms. As indicated above, the delta-Na2S05 form (NaSKS-6) is most preferred for use herein. Other silicates can also be used such as for example magnesium silicate, which can serve as a tightening agent in granulated formulations, as a stabilizing agent for oxygenated bleach, and as a component of foam control systems. Examples of carbonate builders are the alkali metal and alkali metal carbonates as described in German Patent Application No. 2,321,001 published November 15, 1973. Aluminosilicate builders are useful in the present invention . The aluminosilicate builders are of great importance in the majority of heavy duty granular detergent compositions currently marketed, and can also be an important detergency builder ingredient in liquid detergent formulations. The aluminosilicate builders include those that have the empirical formula: [Mz (zAIO2) y] xH2O where z and y are integers of at least 6, the molar ratio of zay is in the range of 1.0 to 0.5, and x is an integer from about 15 to about 264. Useful aluminosilicate ion exchange materials are commercially available. These aluminosilicates can be of crystalline or amorphous structure and can be aluminosilicates present in nature or synthetically obtained. A method for producing aluminosilicate ion exchange materials is described in US Patent 3,985,669, Krummel et al. Issued October 12, 1976. The preferred synthetic crystalline aluminosilicate ion exchange materials useful herein are available under the designations Zeolite A, Zeolite P (B), Zeolite MAP and Zeolite X. In an especially preferred embodiment, the ion exchange material of crystalline aluminosilicate has the formula: Na <; | 2_ (l? 2)? 2 (s¡? 2) i 2JXH2O wherein x is from about 20 to about 30, especially about 27. The material is known as Zeolite A. Dehydrated zeolites (x = O-10) can also be used in the present. 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, "polycarboxylates" refers to compounds having a plurality of carboxylate groups, preferably at least 3 carboxylates. Polycarboxylate builders can generally be added to the composition in acid form, but can also be added in the form of a neutralized salt. When used in the salt form, alkali metal salts such as sodium, potassium and lithium, or alkanolammonium salts are preferred. Included among the polycarboxylate builders are a variety of useful material categories. An important category of polycarboxylate builders comprises ether polycarboxylates, including oxydisuccinate, as described in Berg, US Patent 3,128,287, issued April 7, 1964, and Lamberti et al., US Patent 3,635,830, issued on January 18, 1972. See also "TMS / TDS" detergency builders of U.S. Patent 4,663,071, issued to Bush et al. On May 5, 1987. Suitable ether polycarboxylates also include cyclic compounds, particularly alicyclic compounds, such as those described in US Patents 3,923,679; 3,835,163; 4,158,635; 4,120,874 and 4,102,903. Other useful builders include etherhydroxypolycarboxylates, copolymers of maleic anhydride with ethylene or vinyl methyl ether, 1,3-trihydroxybenzene-2,4,6-trisulfonic acid, and carboxymethyloxy-succinic acid, various alkali metal salts, ammonium and substituted ammonium of polyacetic acids such as ethylenediaminetetraacetic acid and nitrilotriacetic acid, as well as polycarboxylates such as melific acid, succinic acid, oxydisuccinic acid, polymaleic acid, benzene-1, 3,5-tricarboxylic acid, carboxymethyloxysuccinic acid and soluble salts of the same. 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 its biodegradability. The citrates can also be used in granular compositions, especially in combination with zeolite builders and / or layered silicate. Oxydisuccinates are also especially useful in said compositions and combinations. Also suitable in the detergent compositions of the present invention are the 3,3-dicarboxy-4-oxa-1,6-hexanodiates and the related compounds described in US Pat. No. 4,566,984, Bush, issued January 28, 1986. Useful succinic acid builders include the C5-C20 alkyl and alkenyl succinic acids and salts thereof. A particularly preferred compound of this type is dodecenylsuccinic acid. Specific examples of succinate builders include: laurylsuccinate, myristylsuccinate, palmitylsuccinate, 2-dodecenylsuccinate (preferred), 2-pentadecenylsuccinate, and the like. Lauryl succinates are the preferred builders of this group, and are described in European Patent Application 86200690.5 / 0,200,263, published November 5, 1986. Other suitable polycarboxylates are described in the U.S. Patents. Nos. 4,144,226, Crutchfield et al., Issued March 13, 1979, patent E.U.A. No. 3,308,067, Diehl, issued March 7, 1967. See also Diehl, Patent E.U.A. 3,723,322. Fatty acids, for example, monocarboxylic acids of Cl2"Cl 8 >; they may also be incorporated into the compositions alone, or in combination with the aforementioned builders, especially citrate and / or the succinate builders, to provide additional builder activity. Said use of fatty acids will generally result in the decrease of foaming, which should be considered by the formulator. In situations where phosphorus-based builders can be used, and especially in the bar formulations used for hand washing operations, various alkali metal phosphates can be used such as the well-known sodium tripolyphosphates, sodium pyrophosphate. and sodium orthophosphate. Phosphonate builders such as ethan-1-hydroxy-1,1-diphosphonate and other known phosphonates can also be used (see, for example, U.S. Patents 3,159,581, 3,213,030, 3,422,021, 3,400,148 and 3,422,137).

Dispersants The compositions of the present invention may also optionally include at least about 0.1% by weight, preferably from 0.1% to 10%, more preferably from 0.5% to 5% by weight, of a modified or unmodified, substituted or polyalkyleneimine dispersant. Without replacing water soluble, said dispersant includes a polyamine base structure, preferably said base structure has a molecular weight of from about 100 to about 3000 daltons having the formula: H i [H2N-R] n + 1 - [N-R] m- [N-R] n-NH2 wherein R is preferably a C2-C5 alkylene, m ranges from 3 to 70, n goes from 0 to 35, one or more of the hydrogens of the NH units of the base structure of the polyamine are "substituted", this is replaced with a substituent which increases the hydrophilic or hydrophobic dispersion capacity of said polyamine, preferably one or more hydrogens of the base structure, more preferably all of the hydrogens are replaced by a propyleneoxy / ethyleneoxy unit having the formula: - (CH2CHRO) and (CH2CH2?) XH wherein R 'is methyl or ethyl, xyy are preferably 0 to 50, provided that x + y is at least 1; and wherein in addition each nitrogen comprised in the polyalkyleneimine base structure may be optionally "modified" by quaternization or by oxidation to the N-oxide. A further description of the polyalkyleneimine dispersants is found in E.U.A. 4,597,898, VanderMeer, issued July 1, 1986; European Patent Application 1 1 1, 965, Oh and Gosselink, published June 27, 1984; European patent application 1 1 1, 984, Gosselink, published June 27, 1984; European Patent Application 1 12,592, Gosselink, published July 04, 1984; E.U.A. 4,548,744, Connor, issued October 22, 1985; and E.U.A. 5,565,145 Watson et al., Issued October 15, 1996; of which all are included here for reference. However, any anti-redeposition agent or clay or dirt dispersant can be used in the laundry compositions of the present invention.

Dirt releasing agents Any polymeric soil release agent known to those skilled in the art can optionally be used in the compositions and methods of this invention. The polymeric soil release agents are characterized by having both hydrophilic segments to hydrophilize the surface of hydrophobic fibers, such as polyester and nylon, as hydrophobic segments, to deposit on the hydrophobic fibers and remain stuck there until the end of the cycles of washing and rinsing and, in this way, serve as an anchor for the hydrophilic segments. This can cause stains that appear subsequent to treatment with the soil release agent to be removed and cleaned more easily in subsequent washing procedures. If used, the soil release agents will generally comprise from about 0.01% to about 10.0% by weight, of the detergent compositions of the present invention, typically from about 0.1% to 5%, preferably from about 0.2% to about 3%. .

Solvents and vehicle The fabric softening compositions of the present invention may be in liquid form and, therefore, be formulated as an aqueous system or optionally be formulated with a solvent-water system as the liquid carrier. For the liquid fabric softeners of the present invention containing solvents, the solvent preferably constitutes from about less than 40%, preferably from about 10% to about 35%, more preferred from about 12% to about 25%, and even very preferably about 14% to about 20% by weight of the composition. Said solvent is selected to minimize the impact of the solvent odor in the composition and to provide a low viscosity to the final composition. For example, isopropyl alcohol is not very effective and has a strong odor. N-propyl alcohol is more effective, but it also has a distinctive odor. Several butyl alcohols also have odors but can be used for effective clarity / stability, especially when used as part of a solvent system to minimize odor. The alcohols are also selected for optimum low temperature stability, ie they are capable of forming compositions that are liquid with low acceptable viscosities and translucent, preferably transparent, up to about 4.4 ° C and are capable of recovering after storage to about 6.7. ° C. The suitability of any solvent to formulate liquid fabric softener compositions concentrated and preferably transparent in the present with the necessary stability is surprisingly selective. Suitable solvents can be selected based on their octanol / water partition coefficient (P). The octanol / water partition coefficient of a solvent is the ratio between its equilibrium concentration in octanol and in water. The separation coefficients of the main solvent ingredients of this invention are conveniently given in the form of their logarithm in base 10, logP. The logP of many ingredients has been reported; for example, the Pomona92 database available from Daylight Chemical Information Systems, Inc. (Dylight CIS), Irvine, California, contains many, along with quotes from the original literature. However, the logP values are calculated very conveniently by the "CLOGP" program also available from Daylight CIS. This program also lists experimental logP values when these are available in the Pomona92 database. The "calculated logP" (ClogP) is determined by the fragment method of Hansch and Leo (cf., A. Leo in Comprehensive Medicinal Chemistry, Vol. 4. C. Hansch, PG Sammens, JB Taylor and CA Ramsden, Eds. , P. 295, Pergamon Press, 1990, incorporated herein by reference). The fragment method is based on the chemical structure of each ingredient, and takes into account the number and types of atoms, the connectivity of atoms and the chemical bond. The ClogP values, which are the most reliable and widely used estimated values for this physicochemical property, are preferably used in place of the experimental logP values in the selection of the ingredients of a solvent that are useful in the present invention. Other methods that can be used to calculate ClogP include, for example, the Crippen fragmentation method as described in J. Chem. Inf. Comput. Sci., 27, 21 (1987); Viswanadhan fragmentation method, such as that described in J. Chem. Inf. Comput. Sci, 29, 163 (1989); and Broto method as described in Eur. J. Med. Cem. - Chim. Theor., 19, 71 (1984). The solvents herein are selected from those having a ClogP from about 0.15 to about 0.64, preferably about 0.25 to about 0.62 and most preferably about 0.40 to about 0.60, said solvent being preferably asymmetric and preferably having a melting point or solidification that allows it to be liquid at or near room temperature. Solvents that have a low molecular weight and are biodegradable are also desirable for some purposes. The most asymmetric solvents appear to be very desirable, while highly symmetrical solvents such as 1,7-heptanediol, or 1,4-bis (hydroxymethyl) cyclohexane, which have a center of symmetry, appear to be inadequate to provide the compositions essentially transparent when used alone, even though their ClogP values fall in the preferred range. The operable solvents are described and listed later, which have ClogP values that fall within the requirement range. These include mono-oles, diols of C6, diols of C7, isomers of octanediol, derivatives of butanediol, isomers of trimethylpentanediol, isomers of ethylmethylpentanediol, isomers of propylpentanediol, isomers of dimethylhexanediol, isomers of methylheptanediol, isomers of octanediol, isomers of nonanodiol, alkylglyceryl ethers, di (hydroxyalkyl) ethers, and arylglyceryl ethers, aromatic glyceryl ethers, alicyclic diols and derivatives, alkoxylated derivatives of C3-C7 diol, aromatic diols and unsaturated diols. Particularly preferred solvents include hexanediols such as 1,2-hexanediol and 2-ethyl-1,3-hexanediol and pentanediols such as 2,2,4-trimethyl-1,3-pentanediol.

Perfumes The products of the present invention may also contain from about 0.1% to about 60%, preferably from about 1% to about 50%, of cyclodextrin / perfume inclusion complexes and / or free perfume, as described in US patents Nos. 5,139,687, Borcher et al, issued August 18, 1992 and 5,234,610, Gardlik et al, issued August 10, 1993, which are incorporated herein by reference. Perfumes are highly desirable, can usually benefit from protection, and can be complexed with cyclodextrin. Fabric softener products typically contain perfume to provide an olfactory aesthetic benefit and / or to serve as an indicator that the product is effective. The optional perfume ingredients and compositions of this invention are those conventionally known in the art. The selection of any perfume component, or amount of perfume, is based solely on aesthetic considerations. Perfume compounds and appropriate compositions can be found in the art including U.S. Nos. 4,145,184, Brain and Cummins, issued March 20, 1979; 4,209,417, Whyte, issued June 24, 1980; 4,515,705, Moeddel, issued May 7, 1985 and 4,152,272, Young, issued May 1, 1979, all of which are incorporated herein by reference. Many of the perfume compositions recognized in the art are relatively substantive to maximize their odor effect on substrates, however, it is a special advantage of perfume delivery by perfume / cyclodextrin complexes that non-substantive perfumes are also effective . If a product contains both free and complexed perfume, the perfume that escapes from the complex contributes to the overall perfume intensity of the perfume, giving rise to an impression of perfume odor that lasts longer. As described in the patent E.U.A. No. 5,234,610, Gardlik / Trinh / Banks / Benvegnu, issued on August 3, 1993 with said patent incorporated in the present invention as a reference, by adjusting the levels of free perfume and perfume / CD complex it is possible to provide a wide range of unique perfume profiles in terms of synchronization (release) and / or identity of the perfume (character). Solid fabric conditioner compositions, activated in the dryer, are a desirable way to apply the cyclodextrins exclusively, since they are applied at the end of a fabric treatment regime when the fabric is clean and when there are almost no additional treatments that can remove the cyclodextrin.

Stabilizers Stabilizers may be present in the compositions of the present invention. The term "stabilizer" as used herein, includes antioxidants and reducing agents. These agents are present at a level from 0% to about 2%, preferably from about 0.01% to about 0.2%, most preferably from about 0.035% to about 0.1% for antioxidants and still most preferably from about 0.01% to about 0.2. % for reducing agents. These ensure adequate odor stability under long-term storage conditions for the compositions and compounds stored in molten form. The use of stabilizers based on antioxidants and reducing agent is especially critical for products with low aroma (low perfume content). Examples of antioxidants that can be added to the compositions of this invention include a mixture of ascorbic acid, ascorbic palmitate and propylgalate, available from Eastman Chemical Products, Inc., under the trade names Teno? R PG and Tenox S-1; a mixture of BHT (butylated hydroxytoluene), BHA (butylated hydroxyanisole), propylgalate and citric acid available from Eastman Chemical Products, Inc., under the trade name Tenox-6; Butylated hydroxytoluene, available from UOP Process Division under the trade name SustaneR BHT; tertiary butylhydroquinone, Eastman Chemical Products, Inc., as Tenox TBHQ; natural tocopherols, Eastman Chemical Products, Inc, as Tenox GT-1 / GT-2; and butylated hydroxyanisole, Eastman Chemical Products, Inc., as BHA; long chain esters (Cs-C22) of gallic acid, for example dodecyl gallate; Irganox® 1010; Irganox® 1035; Irganox® B1 171; Irganox® 1425; Irganox® 31 14; Irganox® 3125 and mixtures thereof; preferably Irganox® 3125, Irganox® 1425, Irganox® 31 14 and mixtures thereof; most preferred Irganox® 3125 alone or mixed with citric acid and / or other chelators such as isopropyl citrate, Dequest® 2010, available from Monsanto with a chemical name of 1-hydroxyethylidene-1,1-diphosphonic acid (etidronic acid), and Tiro®, available from kodak with a chemical name of 4,5-dihydroxy-m-benzenesulfonic acid / sodium salt, EDDS and DTPA®, available from Aldrich with a chemical name of diethylenetriaminpentaacetic acid.

Concentration Aids Concentrated compositions of the present invention may require organic and / or inorganic concentration aids in order to scale to higher concentrations and / or to meet higher stability standards depending on the other ingredients. Surfactant-based concentration aids are typically selected from the group consisting of single-chain alkyl cationic surfactants, non-ionic surfactants; amine oxides; fatty acids or mixtures thereof, typically used at a level from 0% to about 15% of the composition. Inorganic viscosity / dispersibility control agents that can also act in a similar manner or increase the effect of surfactant-based concentrating agents include ionizable, water-soluble salts that can also be optionally incorporated into the compositions herein invention. A wide variety of ionizable salts can be used. Examples of suitable salts are the halides of group IA and the metals of the HA group of the Periodic Table of the Elements, for example calcium chloride, magnesium chloride, sodium chloride, potassium bromide and lithium chloride. The ionizable salts are particularly useful during the process of mixing the ingredients for making the compositions of the present invention, and then obtaining the desired viscosity. The amount of ionizable salts used depends on the amount of active ingredients used in the compositions and can be adjusted according to the wishes of the formulator. Typical levels of salts used to control the viscosity of the composition are from about 20 to about 20,000 parts per million (ppm), preferably from about 20 to about 11,000 ppm, by weight of the composition.

Other Attached Ingredients The present invention may include other adjunct components (minor components) conventionally used in compositions for treating textiles, for example dyes, preservatives, optical brighteners, opacifiers, anti-shrinking agents, anti-wrinkling agents, fabric tightening agents, coating agents. selective cleaning, germicides, fungicides, anticorrosion agents, antifoaming agents and the like.

EXAMPLE 3 Preparation of 3,7-dimethyl-1,6-octadien-3-yl 3- (β-naphthyl) -3-oxo-propionate 3-Oxo-butyrate 3,7-dimethyl-1,6-octadien-3-yl crude (154.51, 0. 648 moles) from the previous example is placed in a 3000 ml, three-necked round bottom flask equipped with a condenser, argon inlet, addition funnel, magnetic stirrer and internal thermometer. The contents are dissolved in 350 ml of dichloromethane and treated with calcium hydroxide powder (50.44 g, 0.681 mol). The mixture is stirred at 30 ° C for 30 minutes and then heated to 40 ° C. 2-Naphthoyl chloride (142.12 g, 0.746 mol) dissolved in 20 ml of dichloromethane is added dropwise over 15 minutes. The mixture continues to be heated at this temperature for 1 hour. Ammonium chloride (36.41 g, 0.681 mol) dissolved in 250 ml of water is added to the reaction mixture and the pH is adjusted to approximately 9 with 28% ammonium hydroxide. After stirring 30 minutes at 35 ° C the pH is adjusted to 1 with 20% HCl. The mixture is transferred to a separatory funnel containing diethyl ether (500 ml) and water (500 ml). The layers are separated and the organic phase is washed with saturated NaHC 3 solution (2 x 500 mL), dried over MgSO 4, filtered and concentrated by rotary evaporation to give a yellow / red oil. At this point a light yellow solid is precipitated from the mixture. An equal volume of hexane is added and the solids are collected by filtration and dried. The NMR analysis indicates that the solid is 2-naphthoic acid. The eluent is again concentrated by rotary evaporation to give a red oil. The oil is brought to an equal volume of dichloromethane, passed through a plug of silica gel (400 g) and eluted with dichloromethane. The mixture is concentrated by rotary evaporation and separated by Kugeirohr distillation (40 ° C, 0.10 mm Hg, 30 min) to give 173.26 g (76.3%) of the product as a red oil; this product is a mixture of a 1: 10 molar ratio of linalyl acetoacetate to linalyl (2-naphthoyl) acetate.
