Description

METHOD TO REMOVE SKIN MAKE-UP TECHNICAL FIELD The present invention relates to methods for cleaning and removing make-up from the face using personal cleansing surfactant solutions having a low pH and low interfacial tension. These solutions provide appropriate properties to remove silicone-based makeup.

BACKGROUND OF THE INVENTION Personal cleansing products have traditionally been marketed in a variety of forms such as bar soaps, creams, lotions and gels. These cleaning formulations try to satisfy a number of criteria so that they are accepted by the consumers. In order to be accepted by consumers, a product must have good cleansing properties, good foaming characteristics, must be gentle to the skin and preferably should provide a moisturizing benefit to the skin. Ideal personal cleansers should carefully cleanse the skin or hair, cause little or no irritation, and not leave the skin or hair dry after frequent use.

These traditional forms of personal cleansing products include two types of formulations, oil-free cleansers and oil and water emulsions. Oil-free cleaners use water-based surfactants, fatty acid soaps, synthetic isethionates and the like to remove impurities and oil from the skin. However, it has been found that many of these surfactants, especially fatty acid soaps, turn out to be irritating to the skin. Soft components and water-based moisturizers are used to reduce the negative effects of dry skin and irritation. Oil and water emulsions use insoluble skin conditioning oils along with water-based cleaning systems. The products are formulated to balance the cleaning benefits of the water phase and the conditioning benefits of the oils, which are deposited on the skin. However, it is well known that the emulsification of oil cleaners in water has a negative impact on the foaming and cleaning properties of the products. Recently, cosmetic manufacturers have introduced silicone-based makeup, especially lipsticks, that resist dipping and fading. However, since the products are designed to resist removal, by their very nature they are more difficult to remove. Traditional oil-free cleaners and oil and water emulsion cleaners find it difficult to remove these new products, without being irritating to the skin. There is a clear need to develop a method to clean the face and specifically a method to remove makeup from the skin. Surprisingly, it has been found in the present invention that personal cleansing products can be formulated with properties designed to soften and remove silicone from these new makeup products. It has been found that solutions of foaming surfactant and water having a pH less than 8.3 and an interfacial tension of less than 3.5 provide improved stability for removing silicone-based compounds from the skin, without increasing skin irritation. The methods of the present invention are highly effective for cleaning the skin of the face, especially for removing silicone-based compounds therefrom. Without being limited by theory, it is believed that the smaller the typical interfacial tension, the softer and separation of the lipid and silicone base of the make-up compound will be. The lower the pH, the lower the irritation of soap-based products. This combination provides the improved makeup removal benefit of the methods of the present invention. The present invention relates to methods for cleaning compounds based on lipid and silicone of a solid substrate. The present invention also relates to methods for cleaning face skin and methods for removing face makeup using compositions wherein the pH and interfacial tension have been adjusted to remove silicone-based compounds. The methods provide improved cleaning and removal of makeup over traditional methods for cleaning the face. This and other objects of the invention will be apparent from the following disclosure.

BRIEF DESCRIPTION OF THE INVENTION The present invention relates to a method for removing lipid and silicone-based compounds from solid substrates consisting of: applying an effective amount of a cleaning composition containing: a) from about 5% to about 74.5% of an agent foaming surfactant; and b) from about 25% to about 94.9% water; wherein the pH of the composition is less than 8.3 and where the interfacial tension of the composition with mineral oil is less than about 3.5. In another embodiment, the present invention relates to a method for removing lipid and silicone-based compounds from human skin consisting of: applying a safe and effective amount of a cleaning composition containing: a) of about 7.5% to about 50% of a foaming surfactant; and b) from about 50% to about 92.5% water; wherein the pH of the composition is less than about 8.3 and where the interfacial tension of the composition with mineral oil is less than about 3.5. All percentages and proportions used here, unless otherwise indicated, are by weight and all measurements are made to ° C unless otherwise determined. Therefore, the invention may comprise, consist of or consist essentially of the essential ingredients and components as well as optional ingredients described herein.

DETAILED DESCRIPTION OF THE INVENTION I. Cleaning compositions The term "cleaning compositions" as used herein, refers to the composition suitable for application to a solid substrate for the purpose of removing impurities, makeup, oil and the like. The cleaning compositions of the present invention comprise the following essential components.

A. Foaming surfactant The cleaning compositions of the present invention contain from about 5% to about 74.5%, preferably from about 7.5% to about 50%, and most preferably from about 10% to about 25%, based on the weight of the cleaning composition of a foaming surfactant. By "foaming surfactant" is meant a surfactant which, when combined with water and mechanically stirred, generates foam. Preferably, these surfactants must be soft, which means that the surfactants provide sufficient cleaning or detersive benefits but do not dry the skin or hair, and therefore meet the foaming criteria described above. A foaming surfactant is also defined as a synthetic surfactant or a mixture of surfactants having a surface tension balance of between 15 and 50 dynes / cm, most preferably between 20 and 45 dynes / cm as measured in the concentration criticism of miscelas at 25 ° C. Some surfactant mixtures may have a surface tension less than that of their components. As used herein, the term "mild", referring to the foaming surfactants and products of the present invention, means that the products of the present invention demonstrate skin smoothness comparable to a mild alkyl glyceryl ether sulfonate (AGS) surfactant to synthetic bar base (synbar). The methods for measuring the softness, or inversely the irritability, of the products containing surfactants, are based on a test of destruction of the skin barrier. In this test, the milder the surfactant, the less destruction the skin barrier will suffer. The destruction of the skin barrier is measured by a relative amount of water (3H-H20) marked with radium (marked with tritium), which passes from the test solution through the epidermis of the skin to the physiological regulator content in the camera of broadcast material. This test is described T.J. Franz in J. Invest, Dermatol .. 1975, 64, pp. 190-195; and in the patent of E.U.A. No. 4,673,525, a Small and others, filed on June 16, 1987, both incorporated by reference in their entirety. Other test methodologies may also be used to determine the smoothness of surfactants. A wide variety of foaming surfactants is useful herein and includes those selected from the group consisting of anionic foaming surfactants, nonionic foaming surfactants, amphoteric foaming surfactants, and mixtures thereof.
