Abstract

A wiping article is provided which includes an effervescent cleanser composition held within a pouch formed from a first and second substrate sheet. At least one of the substrate sheets must be water permeable. The effervescent composition is an intimate mixture of an acid material such as citric acid and an alkaline material such as sodium bicarbonate. Water contact causes the combination to effervesce. A dry surfactant such as sodium cocoyl isethionate in contact with the water and effervescing carbon dioxide results in a highly pleasant sudsing system. Skin benefit agents may be included within the composition. The effervescent action may improve deposition of the skin benefit agents onto the skin.

Description

PILLOW LIM PIADORA EFERVESCENTE COSM ÉTICA The invention concerns a cleaning, foaming, effervescent article for cleaning the body that imparts a pleasant sensation to the wearer's skin. Classically, the cleaning process of the skin or other articles has employed a surfactant composition. Sometimes a utensil has been attached to the composition. Utensils, such as sacks, serve multiple purposes. A function is a delivery package for the surfactant. Sacks can also help in foam generation. They also work as an abrasive that helps in the cleaning function. An earlier example of cleaning pad technology is found in U.S. Patent 1, 808, 834 (Busch Sr.). A fabric pouch surrounding a cleaning composition, consisting mainly of calcium carbonate and sodium, is described. U.S. Patent 4,234,442 (Cornelissens) discloses a sack, which may consist of a water-permeable material filled with an acid and an alkaline constituent. The adipic, succinic and glutaric acids exemplify the acid constituent. The bicarbonate and sodium carbonate represent the alkaline ingredient. U.S. Patent 4,272,393 (Gergely) discloses a cleaning article formed of a flexible porous substrate, especially a cellulose paper, impregnated with detergent and a gas generating system. The latter is formed by separating an acidic component, such as citric acid, from a basic component, such as sodium carbonate, into two separate areas of the substrate. U.S. Patent 4, 51 5, 703 (Haq), U.S. Patent 4,600,620 (Lloyd et al.) And U.S. Patent 4,603,069 (Haq et al.) Describe cleaning articles impregnated with surfactant. These do not contain effervescent ingredients. WO 97/43366 (Askew et al.) Reports an effervescent system for improving the dispensable capacity of granular laundry detergent powders in washing water of automatic washing machines. Combinations of citric acid and bicarbonate are used to generate effervescence.

An object of the present invention is to provide a cleaning cloth containing an effervescent system activated by contact with water. Another objective of the present invention is to provide a cleaning cloth containing an effervescent system activated by contact with water, to generate carbon dioxide which expands the foam of fabric cleaning components. Still a further objective of the invention is to provide a cleaning cloth that imparts a pleasurable feeling to the skin during and after its use. According to a first aspect, a cosmetic article is provided for cleaning body surfaces, including the article: a pouch formed of first and second sheets, at least one of which is permeable to water, the first and second sheets defining a pouch between them, sealed the bag along its entire perimeter; and an effervescent cleaning composition in the form of an anhydrous dry solid that is placed inside the pouch, the composition comprising: (i) from about 1 to about 80% of an alkaline material; (ii) from about 0.5 to about 80% of an acidic material; and (iii) from about 0.1 to about 30% of a solid surfactant. A method for cleaning skin is also provided, which involves wetting a cosmetic cleansing article with water, generating foam from the article and cleaning skin surfaces with the moistened article, the article being the sachet with the effervescent cleansing composition described above. The cosmetic cleaning articles of the present invention, when in contact with water, swell many times (eg, normally more than 10, but often more than 40 times) their dry size when activated by water. The effervescent cleaning system exudes copious amounts of foam. A swollen "pillow" arises from the effervescent action. By careful control of the acidic and alkaline components, you feel an already rinsed feeling of grinding cleaning on the user's skin. A first essential component of compositions within the pouch is that of an acidic material. Any acid present in dry solid form is suitable for this purpose. Particularly suitable are organic mono- and polycarboxylic acids of C2-C20 and especially the acids alpha- and beta-hydroxycarboxylic acids; organophosphorus acids of C2-C20, such as, phytic acid; C2-C20 organosulfuric acids, such as toluene sulfonic acid; and peroxides such as, hydrogen peroxide. Normal hydroxycarboxylic acids include adipic, glutaric, succinic, tartaric, malic, maleic, lactic, salicylic and citric acids, as well as acid forming lactones, such as, g luconolactone and glucarolactone. The most preferred is citric acid. The encapsulated acids may also be suitable as acidic material. The normal encapsulating material may include natural or synthetic water-soluble polymers, such as polyacrylates (e.g., encapsulating polyacrylic acid), cellulosic gums, polyurethane and polyoxyalkylene polymers. By the term "acid", is meant any substance which when dissolved in deionized water at a concentration of 1%, will have a pH of less than 7, preferably less than 6.5, optimally less than 5. These acids preferably at 25 ° C. C are in solid form, that is, they have melting points not less than 25 ° C. The acid concentrations should vary from about 0.5 to about 80%, preferably from about 10 to about 65%, optimally from about 20 to about 45% by weight of the total composition. A second essential component of the compositions within the pouch is that of an alkaline material. The alkaline material is a substance that can generate a gas, such as carbon dioxide, nitrogen or oxygen, that is, they are in effervescence, when they come into contact with water and the acidic material. Suitable alkaline materials are anhydrous salts of carbonates and bicarbonates, alkaline peroxides (for example, sodium perborate and sodium percarbonate) and azides (for example, sodium azide). Preferably, the alkaline material is sodium or potassium bicarbonate. The amounts of the alkaline material may vary from about 1 to about 80%, preferably from about 5 to about 49%, more preferably from about 1 to about 40%, optimally from about 25 to about 35% by weight of the total composition. By the term "anhydrous" is meant the presence of not more than 5%, preferably not more than 3.5% and optimally not more than 1% water by weight of the total composition. Hydration water is not considered as water for the purpose of defining anhydrous. However, it is preferred to minimize, and preferably eliminate any water of hydration. Advantageously, the combined amount of acidic and alkaline materials will be at least about 1.5%, preferably from about 40 to about 95%, optimally from about 60 to about 80% by weight of the total composition.

The amounts of the deposition aid can vary from about 0.01 to about 1%, preferably from about 0.05 to about 0.5%, optimally from about 0.1 to about 0.3% by weight. Advantageously, an emotive agent, such as a fragrance and / or botanical extract, are included with the effervescent cleaning composition. Fragrances and botanical extracts are frequently liquids. For this reason, it is necessary to distribute evenly and allow the absorption of liquid components in the solid powder. A method to achieve this better, is to atomize these liquids on solids. The amounts of the fragrance and / or combined botanical extracts can be at levels from about 0. 1 to about 3%, preferably from 0.5 to 2%, optimally from 0.8 to 1.5% by weight of the total composition. The term "fragrance" is defined as a mixture of odorant components, optionally mixed with a suitable solvent, diluent or carrier, which is employed to impart a desired odor. The preferred particular odorant components are terpenes and cyclic and acyclic terpenoids. These materials are based on repetitive isoprene units. Examples include alpha and beta pinene, myrcene, geranyl alcohol and acetate, camphene, dl-limonene, alpha and beta phellandrene, tricyclene, terpinolene, alkoimano, geraniol, nerol, linanool, dihydrolinanool, citral, ionone, methyl ionone, citronellol, citronellal, alpha terpineol, beta terpineol, alpha phenol, borneol, isoborneol, camphor, terpinen-1-ol, terpin-4-ol, dihydroterpineol, methyl cavicol, anethole, 1, 4 and 1, 8 cineol, geranyl nitrile, isobornyl acetate, linalyl acetate, caryophyllene, alpha cedrene, guaiol, patchouli alcohol, alpha and beta santalol and mixtures thereof. Botanical extracts of particular use in the present invention include yarrow, chamomile, jasmine, lavender, horse chestnut, mugwort, thyme, yucca, coltsfoot and mixtures thereof. Conservatives may be desirably incorporated into the cosmetic compositions of this invention, to protect against the growth of potentially harmful microorganisms. Suitable traditional preservatives for compositions of this invention are aqluyl esters for para-hydroxybenzoic acids. Other preservatives that have come into use more frequently include hydantoin derivatives, propionate salts and a variety of quaternary ammonium compounds. Cosmetic chemists are familiar with the appropriate preservatives and choose them routinely to satisfy the conservative challenge test and to provide stability to the product.

Particularly preferred preservatives are phenoxyethanol, methyl paraben, propyl paraben, imidazolidinyl urea, sodium dehydroacetate and benzyl alcohol. Conservatives should be selected with respect to the use of the composition and possible incompatibilities between the preservatives and other ingredients in the emulsion. The preservatives are used, preferably in amounts ranging from 0.1% to 2% by weight of the composition. Frequently natural plant materials of renewable resources are desirable in the cosmetic compositions. For example, the cosmetic compositions of the present invention may include beta-g lucan derived from oats, commercially available under the trademark Microat SF from Nurtur Inc., Missoula, Mont. Dyes may also be included in the compositions of the present invention. These substances can vary from about 0.05 to about 5%, preferably between 0. 1 and 3% by weight. The effervescent cleaning compositions of this invention will be placed within a sack formed between a first and second flexible substrate sheet, preferably at least one of these is a flexible sheet. At least one of the sheets must be permeable to water, most preferably both sheets should have water permeability. For definition purposes, the first and second sheets may be bent panels of a single unitary sheet. Suitable materials for forming sheets can be rayon, polyester, polyethylene, polypropylene, cotton or any other combination thereof. These lamps can be woven or non-woven. A non-woven rayon is much preferred. Substrates of paper fibers are best not used due to their insufficient strength to moisture, although they can be mixed with other fibers referred to above; it is important that the substrate sheets do not open easily in a precipitous manner as the consumer rubs the article. Unlike articles of laundry bags, the bags of the present invention should not be broken to allow the dispersion of their granular contents in wash water. Instead, it is intended that the cleaning composition components come out by dissolution through the permeable walls of the pouch. The surfaces of the skin against which the articles of the present invention are useful, include face, body, scalp, armpits and even legs / feet. When the article is a foot cleaner, it would be advantageous for the pouch if one of its sides is thicker, while the second of the sheets may be soft and soft. A flexible, non-woven, abrasive sheet in a foot cleaning product is useful for rubbing against calluses, while the second sheet of the bag remains soft. The articles according to the present invention can be formed in the following manner. The constituents of the effervescent cleaning composition are placed in a dry mill or similar apparatus, and mixed until a uniformly distributed powder results. Subsequently, the fragrance / botanical extract component as a second phase is atomized in the dry mill with concurrent agitation of the powder composition. A continuous roll of the first substrate sheet is unwound from a source roll on a moving conveyor belt. The effervescent cleaning composition is placed in a hopper located on the conveyor belt. A discrete charge of powder composition is regularly placed on the first sheet of substrate at a location directly below a hopper nozzle. A second sheet of substrate is placed in register on that of the first sheet of loaded substrate. At this point, the four corners that define a rectangle or square are sealed in register, trapping the effervescent cleaning composition inside. The cutters then separate one sealed section from the other, thereby forming the cleaning article. One or more of the cleaning articles are then packaged in an outer moisture-impermeable package, such as a laminated sheet pouch to prevent activation of the effervescent system during storage. Ultrasonic welding can be employed as an alternative to heat sealing of the first and second substrates together. Stitching with thread, glue application or other locking mechanisms can also be used. Except in the operation and comparison examples, or where explicitly stated elsewhere, all numbers in this description will be understood to indicate quantities of material as modified by the word "approximately".

The term "comprises" does not mean that it is limiting to any of the elements declared subsequently, but that it covers unspecified elements of greater or lesser functional importance. In other words, the steps, elements or options listed do not need to be exhaustive. The following examples will more fully illustrate the embodiments of this invention. All parts, percentages and proportions referred to herein and in the appended claims are by weight, unless otherwise indicated.

EXAMPLE 1 An effervescent cleaning composition was prepared according to the formulation reported in Table I. Phase A was mixed dry in a high speed cutting mixer. The fragrance was then atomized onto the resulting powder as a B phase. Three grams of the resulting powder was then placed in a 5.1 cm by 7.6 cm sachet formed of non-woven rayon. All sides were closed by double stitching with thread.

TABLE I EXAMPLE 2 Another effervescent cleaning composition was prepared according to the formulation reported in Table II.

TABLE II EXAMPLE 3 An effervescent cleansing composition for the face was prepared according to the formulation reported in Table III.

TABLE III EXAMPLE 4 Still an additional effervescent cleaning composition according to the present invention, can be prepared according to the formulation reported under Table IV. Phase A is prepared by dry mixing the ingredients in a high speed cutting mixer. Three grams of the resulting powder is placed in a 5. 1 cm by 7.6 cm sachet, formed of non-woven cotton polyester (50: 50). The size of the mesh of the walls of the bag is sufficient to allow the transfer of the dissolved ingredients. All sides of the sachet are welded by ultrasonic heat to ensure that dust does not escape from the pouch.

TABLE IV EXAMPLE 5 Still another effervescent cleaning composition is prepared in accordance with the formulation reported in Table V. The ingredients are mixed dry in a high speed cutting mixer. The fragrance and herbal extract are atomized in the powder and mixed further to achieve homogeneity. Three gums of the resulting powder are placed in a 5.1 cm by 7.6 cm pouch formed of non-woven polypropylene. All sides are closed by heat sealing by convection along the perimeter of the same.

TABLE V The description and examples above illustrate selected embodiments of the present invention. In light of them, it ^^ i ^ ü ^! ^^ will suggest variations and modifications to one skilled in the art, all being within the spirit and incumbency of this invention.
