Description

BACKGROUND OF THE INVENTION

[0002] A. Field of the Invention

[0003] The present invention relates generally to flexible, fine-pored sponges or foam pads impregnated with liquids. More particularly, the foam pads are based on a polyurethane foam and are obtained as in situ reaction products of a urethane prepolymer with free isocyanate groups and an aqueous phase, which contains at least one surface-active substance and cosmetic or dermatological active ingredients or care and maintenance ingredients. The foam pads are used for the cosmetic or dermatological treatment of the skin, hair, mucosa, and appendages of the skin.

[0004] B. Description of the Related Art

[0005] Flexible support materials, e.g. cloths and foam pads, that are saturated or impregnated with liquid cosmetic compositions, are extremely popular among consumers. They are time-saving, clean, and hygienic to use. The support materials often consist of nonwoven fleece, cotton, or microfibers.

[0006] Cosmetic foam pads based on in situ reaction products of a urethane prepolymer with free isocyanate groups and an aqueous phase are known in the art. For example, U.S. Pat. No. 4,806,572 describes foam pads, which are formed in situ from a urethane prepolymer with free isocyanate groups and an oil-in-water emulsion and are used for makeup removal. The emulsion contains anionic and nonionic surfactants and liquid oil components and is free of natural or synthetic waxes. U.S. Pat. No. 4,548,954 describes an oil-absorbing floor cleaner, which is formed in situ from a urethane prepolymer with free isocyanate groups and an aqueous silicone oil emulsion that contains abrasive particles. U.S. Pat. No. 4,127,515 describes a product for waxing and polishing floors, which is formed in situ from a urethane prepolymer with free isocyanate groups and an aqueous silicone oil emulsion that contains wax and a polyacrylate.

[0007] The advantage of in-situ foaming of the urethane prepolymer with the cosmetic or dermatological composition compared to conventional methods of impregnation is that it is a one-step process, i.e. the support material is impregnated with the liquid during the production process itself and does not have to be sprayed or impregnated with it in a second process step.

[0008] The foaming process and the quality of the final product depend to a great extent on the composition of the liquid that is used.

SUMMARY OF THE INVENTION

[0009] The present inventors have found, surprisingly, that flexible, fine-pored foam pads may be obtained from the in situ reaction product of a urethane prepolymer with free isocyanate groups and a liquid aqueous phase that contains emulsifiers and cosmetic or dermatological active ingredients and care and maintenance ingredients, and that these foam pads have a pleasant slip on the skin and hair surfaces to be treated and allow controlled, drip-free deliver), of the liquid bound in the pores. The foams in accordance with the invention can be cured, cut, or punched into any desired shapes, preferably shapes adapted to the intended type of use.

[0010] Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0011] The following detailed description of the invention does not limit the invention. Instead, the scope of the invention is defined by the appended claims and equivalents thereof.

[0012] The present invention is broadly drawn to a flexible support material impregnated with liquid, which is intended for the cosmetic or dermatological treatment of the skin, hair, mucosa, and appendages of the skin. The flexible support material is based on a polyurethane foam that contains the in situ reaction product of a urethane prepolymer with free isocyanate groups and a liquid aqueous phase that contains at least one surface-active substance and at least one dispersed fatty substance. The present invention is characterized by the fact that the liquid phase additionally contains at least one cosmetic or dermatological active ingredient or care and maintenance ingredient, which is selected from among natural and, if desired, chemically modified polymers, which in turn are selected from among cellulose ethers, quaternized cellulose derivatives, polyquaternium 24, guar gum, cationic guar derivatives, alginates, xanthan gum, gum arabic, karaya gum, carob bean flour, linseed gums, dextrans, shellac, amylose, amylopectin, dextrins, chemically and/or thermally modified starches, and chitosan and its derivatives, as well as synthetic polymers that do not act as superabsorbers but rather swell with water and are thereby converted to a gel-like true or colloidal solution, α-hydroxycarboxylic acids and their derivatives, vitamins, provitamins and vitamin precursors of the groups B. C, and B and their derivatives, plant extracts, selected from among the plant formative tissues that are capable of dividing (meristem), green tea (Camellia sinensis), hamamelis, chamomile, marigold, pansy, peony, horse chestnut, sage, willow bark, cinnamon tree, chrysanthemums, oak bark, nettle, hops, lappa, horsetail, hawthorn, linden flowers, almonds, spruce needles, sandalwood, juniper, coconut, kiwi, guava, lime, mango, apricot, wheat, melon, orange, grapefruit, avocado, rosemary, birch, beech sprouts, mallow, cuckoo flower, yarrow, wild thyme, thyme, balm mint, restharrow, marsh mallow (Althaea), common mallow (Malva sylvestris) violet, leaves of the black currant, coltsfoot, cinquefoil, ginseng, ginger root, sweet potato, olives (Olea europaea) and citrus fruit seeds, extracts of algae and microorganisms, active substances with antiperspirant activity, selected from among astringent water-soluble aluminum, zinc, and zirconium salts and mixtures thereof, active substances with deodorant activity, silicic acids, natural and synthetic silicates, aluminosilicates, kaolin, talc, and apatites, which may be modified with aqueous carboxylic acids with 2-3 C atoms, pigments, selected from among the oxides of titanium, iron, zinc, zirconium, cerium, magnesium, and bismuth, which, if desired, may be surface-modified, boron nitride particles, water-insoluble nacreous pigments and water-insoluble organic pigments, water-soluble and oil-soluble organic sunscreens, cosmetic abrasives, selected from among polymer particles and vegetable abrasives, which, if desired, may be covered with fatty substances, dyes and oxidation dye (intermediates) for dyeing keratinous fibers, oxidizing agents, reducing agents, and active substances with sebum-regulating, skin-soothing, anti-inflammatory, astringent, or perfusion-promoting activity.

[0013] Urethane prepolymer compositions suitable for producing the foam pads of the invention are described, for example, in U.S. Pat. Nos. 3,903,232 and 4,137,200. Corresponding commercial products came from the Hypol® product line of W. R. Grace & Co., Lexington. MA, e.g., Hypol® FHP 5000, Hypol® FHP 4000, Hypol® FHP 3000, Hypol®FHP 2000, Hypol® FHP 2000 HD, Hypol® FHP 2002. Hypol® 2000. Hypol® 2002. Hypol® 3000, Hypol® X6100 and Hypol® Hydrogel, now offered by Dow Chemical Company. The liquid resins are produced by reacting polyols of low molecular weight and 3-8 hydroxyl groups with aromatic or aliphatic diisocyanates. After the reaction, the resins have at least two free isocyanate groups per molecule of polylol used. Examples of suitable diisocyanates are toluene diisocyanate, methylene diphenyl isocyanate and isophorone diisocyanate. Other suitable commercial products come from the Aquapol® product line of Freeman Chemical Corporation and the Trepol® product line of Twin Rivers Engineering.

[0014] When in contact with excess water from the liquid aqueous phase of the invention, which contains at least one surface-active substance and cosmetic or dermatological active ingredients and care and maintenance ingredients, the free isocyanate groups of the urethane prepolymer hydrolyze with evolution of carbon dioxide. This results in the formation of fine-pored foam pads impregnated with the aqueous phase, which contains the active substances.

[0015] The foamed material can then be converted to various shapes adapted to the specific type of intended application using conventional methods.

[0016] The surface-active substances used in accordance with the invention, which are called surfactants or emulsifiers, depending on the area of application of the substance, are selected from among anionic, cationic, dipolar-ionic (or zwitterionic), ampholytic, and nonionic surfactants and emulsifiers.

[0173] In accordance with the invention, oxidizing agents and reducing agents that are suitable for use on the human body may also be used.

[0174] Oxidizing agents are used in hair cosmetics, on the one hand, to produce permanent hair dyeing with the use of oxidation dye intermediates of the developer and coupler type by oxidatively coupling the two intermediate types with each other. In this regard, either the hair is first treated with the oxidation dye intermediates and then with the oxidizing agent, or the oxidation dye intermediates and the oxidizing a gent are mixed immediately before use and then applied to the hair.

[0175] On the other hand, oxidizing agents are used to fix a permanent hairstyle (permanent wave) after the reductive wave treatment of the hair. Suitable oxidizing agents are persulfates, chlorites, sodium bromate, potassium bromate, and especially hydrogen peroxide or its addition products with urea, melamine, and sodium borate. The especially preferred hydrogen peroxide is used together with customaray stabilizers for stabilizing aqueous hydrogen peroxide preparations. The pH of these types of aqueous H2O2 preparations, which usually contain about 0.5-15 wt. % H2O2, or, in the case of ready-to-use formulations, about 0.5-3 wt. % H2O2, is preferably 2-6, and especially 2-4, and is adjusted by acids, preferably phosphoric acid, phosphonic acids, and/or dipicolinic acid. Bromate-based fixatives usually contain the bromates in concentrations of 1-10 wt. %, and the pH of the solutions is adjusted to 4-7. It is also possible to carry out the oxidation with the use of enzymes. The enzymes are used both to produce oxidizing per-compounds and to potentiate the effect of small amounts of oxidizing agents that are present or the enzymes are used to transfer electrons from suitable developer components (reducing agents) to atmospheric oxygen. Oxidases are preferred, for example, tyrosinase, ascorbate oxidase, and laccase, as well as glucose oxidase, uricase, or pyruvate oxidase. Reducing agents are used in cosmetics chiefly for permanent hair styling, for which they are applied to hair curled on curlers for the purpose of breaking the disulfide bridges of the keratin.

The mixture is stirred vigorously for 10 seconds and then poured into an open cylindrical mold with a diameter of 6 cm. The mixture is allowed to foam and cure in this mold. The foamed body produced in this way can be cut into disks or other suitable shapes after two hours. The foam pads described in the other examples are similarly produced.
