    "AQUEOUS COMPOSITIONS AND HAIR CLEANING METHOD" DESCRIPTIVE REPORT
    TECHNICAL FIELD
    The present disclosure relates to compositions and methods for cleaning substrates based on keratin such as hair. In particular, the disclosure relates to hair cleaning compositions comprising an alkyl polyglycoside, a betaine compound, and an acyl amino acid, the composition being sulfate free.
    BACKGROUND
    [0002] Consumers of personal care products and cosmetics consider many factors in the selection of products for use. Recently, certain factors have had a focus on and led product development and scientific study. These determining factors for hair care products include environmental impact, as components condition hair, and the aesthetic quality of the overall product including clarity and foaming / lathering. In addition, the effort towards environmental impact awareness is a universal issue and consumers are increasingly selective about the biodegradability of the personal care and cosmetic products they acquire.
    Hair care products that are sulfate free currently exist in the market, however, they tend to have certain undesirable properties such as lack of lathering or lack of foaming performance, mild hair cleansing, lack of clarity especially in the presence of oils and fragrances, and poor total viscosity.
    In addition, the currently available sulfate-free hair care compositions require the addition of emulsifiers, thickeners, polymers and / or hydrocolloids to stabilize and solubilize the conditioning agents and improve viscosity. There are disadvantages to using emulsifiers, thickeners, polymers and hydrocolloids. For example, alkoxylated emulsifiers may be ecotoxicants and the production process of them is generally environmentally harmful. In addition, common thickeners, polymers, and hydrocolloids tend to bioaccumulate and resist biodegradability, or have a negative effect on the foaming performance of the product. Accordingly, it is desirable to provide a composition which has improved sustainability and is biodegradable and non-toxic when compared to traditional shampoo formulations, while maintaining favorable viscosity, foaming and cleaning properties.
    Thus, the present disclosure relates to the hair cleaning formulation which forms a visually clear cleaning composition with notable improvement in viscosity (gel-like appearance), stability and solubility of conditioning agents without the need for emulsifiers such as surfactants alkoxylates or polyglycerol esters, thickeners such as glycol esters or glycol ethers, thickening or stabilizing polymers such as acrylic acid copolymers and polymers, and naturally derived or hydrocolloid gums such as cellulose derivatives, guar gums or xantham. Emulsifiers are generally described as ingredients which can be classified as surfactants, however, they have properties that help to form and stabilize an emulsion consisting of two phases such as phase containing oil and water. Such emulsifiers are typically alkoxylated and have PEG, PPEG or polyglycerol functionalities. Surfactants are defined as ingredients that have the ability to modify the interface between two immiscible phases by reducing the surface tension and serve as a cleaning and detergency function.
    BRIEF SUMMARY OF THE DESCRIPTION
    In particular, the composition according to the disclosure demonstrates superior hair cleaning performance, excellent clarity, and improved texture and abundance of foaming, even in the presence of oils and fragrances, compared to other formulations of caution sulfate free hair. Additionally, the compositions according to the description are classified as "readily biodegradable".
    The present disclosure relates to an aqueous hair cleansing composition comprising (a) at least one alkyl polyglycoside; (b) at least one betaine compound; (c) at least one acyl amino acid, the composition being sulfate free. In another embodiment, the present disclosure also relates to the aqueous hair cleansing composition as defined above, also comprising at least one surfactant.
    Another object of the disclosure is a method for cleaning the hair, comprising applying the composition (s) described above to the hair.
    DETAILED DESCRIPTION OF THE DESCRIPTION
    The present hair cleaning formulation forms a visually clear cleaning composition with notable improvement in viscosity (gel-like appearance), stability, and solubility of conditioning agents without the need for emulsifiers, thickeners, polymers and hydrocolloids. Also, the present composition demonstrates superior performance in hair cleansing, excellent clarity, and improved foaming texture and abundance, even in the presence of oils and fragrances, compared to other sulfate-free hair care formulations. Additionally, the compositions according to the description are classified as "readily biodegradable". "Easily biodegradable" is a classification term designated by the Organization for Economic Cooperation and Development (OECD) that determines the rate of biodegradation of an organic chemical. Various test methods may be used in determining the biodegradability of a compound. "Easily biodegradable" materials are tested using the stringent methods presented by the OECD and a passage result indicates rapid biodegradation in most environments. For complete information on test methods, please refer to OECD Guidelines for Testing of Chemicals Section 3, July 2003. Organization for Economic Cooperation and Development (OECD) available at http://www.oecd.Org/dataoecd /38/2/5598432.pdf.

    The present disclosure also relates to a method of cleaning hair. The process involves contacting the hair fibers with the composition described above.
    The present composition will be better understood by the following examples, all of which are intended for illustrative purposes only and are not unduly intended to limit the scope of the invention in any way.
    EXAMPLES
    The Examples of Formulation 1-3 above were prepared by combining and blending the listed ingredients and heating to 50Â ° C. All formulations of Examples 1-3 are clear, slightly yellow, gel-like compositions. The clarity of the formulation was measured by the percentage of light transmittance at a wavelength of 700 mm by spectrophotometry Visible by UV. Clear formulations allow between 90% and 100% of the light to pass through the formula. Specifically, the clarity of the formulation of Example 3 is 92.4%. The viscosity of the formulation of Examples 1-3 varies depending on the particular combination of conditioning agents used. In particular, the viscosity of the formulation of Examples 1-3 ranges from 1500 cP to 20000 cP (measured using the Brookfield viscometer at 50 RPM using T-C axis). Thus, although the present composition may exclude emulsifiers, thickeners, polymers, and hydrocolloids, the formulation still exhibits a viscosity in the range of 1500 cP to about 20,000 cP.
    Table 2: Comparative Example 1 In Comparative Example I, various attributes of the present composition and Hydrate Shampoo Pureology were compared. The Pureology of Hydrate Shampoo is non-sulphate, but includes polymers and emulsifiers. The test was performed in 8 members. As shown above in Table 2, the present composition (formulation of Example 1) provides very similar attribute qualities like Hydrate Shampoo Pureology. Specifically, differences exist only in the attributes categories of soft hair sensation in the soaping, (rinsing) malleability, softness, static fluctuation, and thorough cleaning. Thus, although the present composition may exclude emulsifiers, thickeners, polymers, and hydrocolloids, it generally still provides similar attribute qualities as those compositions which include polymers and emulsifiers.
    Table 3: Comparative Example 2 In Comparative Example 2, various attributes of the present composition and Pure Fructis Cleaning Shampoo were compared. Fructis Pure Cleaning Shampoo is 94% biodegradable, however, contains sulfate surfactants. As shown above in Table 3, the present composition (formulation of Example 2) provides very similar attribute qualities as Pure Fructis Cleansing Shampoo. Specifically, differences exist only in the categories of abundant foam attribute, thorough cleansing and damp hair combing. Thus, although the present composition is sulfate-free, it generally still provides similar attribute qualities as those compositions which include sulfates.
