Description

Title of the invention: Skin cleansing composition having a malleable pasty solid texture

[0001] The present patent application relates to a solid skin cleansing composition having the particularity of having a malleable pasty texture and comprising water, xanthan gum, at least one acylglutamate, at least one alkylpolyglucoside, candelilla wax and carnauba wax, and calcium carbonate and hydroxyapatite. The invention also relates to a method for obtaining this solid skin cleansing composition, a method for cleansing the skin with the skin cleansing composition according to the invention, and the use of said composition for washing the skin of an individual, preferably of the body or face.

[0002] Cosmetic products for cleansing the skin of the body and face are typically in liquid, gel, or cream form. These formulations are not always practical for the consumer, particularly those who are required to use such soap outside the home, for example when traveling, hiking, or engaging in other activities outside the home.

[0003] In addition, these liquid compositions are mostly packaged in plastic containers, which cause environmental pollution. Many non-governmental agencies highlight these recurring problems in the cosmetics and personal care industry.

[0004] Reducing these plastic packagings is therefore essential, and society tends to eliminate them when possible. The need for easily transportable washing compositions has also become apparent.

[0005] The development of solid washing compositions has thus accelerated in recent years, to respond to these problems.

[0006] Existing solid washing compositions mostly take the form of a bar of soap. These solid washing formulations nevertheless bring their share of inconvenience and difficulties of use.

[0007] All of the solid washing compositions available today are in fact difficult to apply for the user, who must use a very large quantity of water in order to emulsify said composition. In addition, such solid compositions which do not emulsify easily are not pleasant for the user accustomed to liquid washing solutions which emulsify easily.

[0008] The homogeneity of the application of these solid compositions on the body and face is also problematic.

[0009] Furthermore, these solid washing compositions tend to slide easily from the hand, and their use is therefore more complicated for the user.

[0010] These compositions in solid form also melt on contact with water on a soap dish, and thus result in a loss of product for the user.

[0011] This loss of product is also linked to the fact that compositions in solid form are difficult to dose to obtain optimal efficiency, and waste could therefore be avoided.

[0012] Thus, there remains a need for a skin cleansing composition that is strong and effective and solves all of the problems set out above, and which is therefore in particular easier to apply and which emulsifies more easily.

[0013] The Applicant has solved these problems by developing a solid pasty composition made malleable by its ingredients and the concentration thereof, stable over time and which thus allows easier application and emulsion.

[0014] In addition, its texture and packaging allow you to take only the desired and optimal quantity for cleaning the skin of the body and face, and to prevent contact with water of the unused product.

[0015] Thus, according to a first aspect, the invention relates to a skin cleansing composition having a malleable pasty solid texture.

[0016] According to a preferred embodiment, said skin cleansing composition, having a malleable pasty solid texture, comprises: • Water; • Xanthan gum; • At least one acylglutamate; • At least one alkylpolyglucoside; • Candelilla wax and carnauba wax; • Calcium carbonate and hydroxyapatite.

[0017] By "skin cleansing composition" is meant a cosmetic composition for removing unwanted substances from the user's skin such as, for example, dirt, infectious agents and other impurities. Skin cleansing compositions are otherwise known as "soap". The skin cleansing carried out within the scope of the invention is carried out on a healthy subject, and the composition according to the invention is therefore non-therapeutic. This composition is used in individuals with healthy skin, for cleansing.

[0018] Preferably, the skin is that of the user's body or face.

[0019] By "solid texture" is meant a composition whose formulation has a compact, non-liquid appearance, which does not spread over a surface on which it rests. The active compounds of the composition are activated upon contact with water during their use, and thus act on the skin to cleanse it.

[0020] By "malleable pasty" is meant according to the invention that said solid composition is in the form of a paste that can be deformed or molded under pressure, for example, from the user's fingers, and thus makes it easier to apply to the skin of the user's body or face compared to a conventional solid soap. A malleable paste texture within the meaning of the invention is similar to the texture of a modeling clay. Thus, the composition according to the invention has a viscosity similar to that of modeling clay.

[0021] This solid, malleable, pasty texture is obtained by combining the above compounds.

[0022] The composition described above comprises, in addition to the active ingredients specified above and determining its texture, compounds allowing in particular the cleaning and maintenance of the skin of the body and face. The present composition can therefore constitute a washing base to which washing active ingredients can be added.

[0023] At the environmental level, the composition according to the invention and its packaging make it possible to limit the ecological impact. In particular, the composition according to the invention comprises 70% less water than a conventional soap. Indeed, in a conventional liquid soap there is 80% water, whereas in the washing composition which is the subject of the invention there is only 10 to 25%.

[0024] According to one embodiment, the skin cleansing composition, having a malleable pasty solid texture, according to the invention comprises: • From 10 to 25% water by weight of the composition.

[0025] Preferably, the water used is osmosis water.

[0026] Alkylpolyglucosides and acylglutamates are surfactants. A surfactant is a water-miscible compound that reduces the surface tension between the keratin fiber and the dirt. It thus allows the dirt to be emulsified and removed during rinsing. It is the mixture of surfactants according to the intrinsic properties of each that allows a stable foam to be obtained.

[0027] The composition according to the invention uses surfactants which are among the mildest among the large family of surfactants.

[0028] Alkyl polyglucosides or (APGs) are a class of biodegradable nonionic surfactants derived from sugars, typically glucose and fatty alcohols. Derived from starch and fats as raw materials, the end products of APGs are typically complex mixtures of compounds with different sugars at the hydrophilic end and alkyl groups of varying length at the hydrophobic end.

[0029] Acylglutamates are anionic surfactants derived from glutamic acid. They are composed of a C8 or higher chain fatty acid and L-glutamic acid, and are obtained by acylation reaction and neutralization with a strong base (soda).

[0030] Glutamic acid and fatty acids are beneficial for the skin. If you apply a acylglutamate on the skin, it is cleaved by enzymes and the two original components are then obtained: fatty acid and glutamic acid.

[0031] This means that there will be no surfactant residues on the skin, a specific and essential property of acylglutamates. By applying these surfactants, the skin is restored to its physiological components.
