A method for producing functionalized nanocrystalline cellulose, the method comprising the steps of providing cellulose, mixing said cellulose with a peroxide, thereby producing a reaction mixture, and heating the reaction mixture, and/or exposing the reaction mixture to UV radiation is provided. Functionalized nanocrystalline cellulose produced by this method is also provided.

A cosmetic element (3), in particular a make-up product, formed by a first cosmetic product (4) and at least a second cosmetic product (5) different from the first one; the first cosmetic product (4) is a matrix inside of which a plurality of macroscopic corpuscular units (6) are sunk, formed by said at least one second cosmetic product (5).

Disclosed herein are cosmetic lip compositions that contain dried food powders. The dried food powders are present in about 1% to about 20% and impart flavor to the lip compositions. The lip compositions can be solid (e.g., balms, lipsticks) or semi-solid (e.g, gels in tubes) and can be made using known manufacturing processes.

Disclosed is a cosmetic composition spread on lips to provide a color to lips. Disclosed are a lip pack cosmetic composition for tattooing and a method of preparing the same wherein lips are pigmented and thereby have tattoo effects by removing a formed layer after pigmenting a color on lips and drying the pigmented lips.

The present invention relates to a process for treating keratin materials, preferably human skin, in particular the lips, preferably in at least two steps involving, in a first stage, the application to said materials of an oily dispersion (A) comprising i) particles of copolymers of alkyl acrylates and of anhydride acrylics, ii) stabilizers, iii) one or more hydrocarbon-based oils; and then, in a second stage, the application to said materials of a composition (B) comprising iv) one or more amine compounds, it being understood that the process of the invention uses v) one or more cosmetic active agents chosen from a) pigments, b) active agents for caring for the skin, and c) UV-screening agents and also d) mixtures thereof; ingredients a) to d) possibly being found in composition (A), and/or in composition (B), and/or in another composition (C).

The process of the invention makes it possible to obtain a treatment of said keratin materials that is notably resistant to sweat, to shower gels, to water and to fatty substances, in particular plant or animal food oils, and more particularly plant oils such as olive oil, sunflower oil, walnut oil, hazelnut oil, etc.

The keratin material treatment process of the present patent application is also suitable for making up the skin or the lips, such as foundations and lipsticks.
