Described herein is a nanofibre matrix comprising 100% natural biopolymers selected from polysaccharides and/or proteins with optional functional ingredients for use as cosmetic products. More specifically, nanofibre matrix manufactured by electrospinning methods comprising a dry sheet without containing any preservatives, surfactants, solvents and crosslinkers. To use nanofibre cosmetic products, simply wet skin and then apply the nanofibre to skin. Functional ingredients may be optionally incorporated within the nanofibre matrix during electrospinning to provide different cosmetic effects. Functional ingredients offer skin benefits such as moisturizing, anti-ageing, wrinkle reduction, brightening, antioxidant and acne treatment. Functional ingredients can be essential oil where it is incorporated into nanofibre matrix to provide scent effect to cosmetic products. Functional ingredients can also be natural dye where it is incorporated in nanofibre matrix to make coloured nanofibres. Coloured nanofibres can be used for makeup products such as blush, eye shadow, eyebrow, nail polish, lipstick, contouring and hair dye product. The nanofibre matrix comprising 100% natural biopolymers with or without functional ingredients can be processed to assorted shapes or easily cut by consumers for using on different areas of skin for different purposes.

The present invention is intended to provide an oily makeup cosmetic that is colorless in appearance but develops a color on application onto body surface, such as skin and lips. The present invention provides a colorless oily makeup cosmetic comprising (a) one or two dyes selected from Red No. 218 and Red No. 223, and (b) an oil agent, and a mixture of the component (a) and the component (b) at a mass ratio (a):(b) of 0.1:100 has a difference of 0.2 or less between the maximum absorbance and the minimum absorbance in a wavelength region of 500 to 600 nm. The oily makeup cosmetic may develop a color due to the component (a) on application onto body surface, such as skin and lips.

A cosmetic ingredient for cosmetic products has a polymer structure which includes an emollient or film-forming cosmetic polymer which is transparent to light. An organic chromophore molecule is inserted and chemically linked into the polymer, which can be a fixed color molecule or a photochromic molecule capable of rapidly switching from one color to another. The colored or photochromic molecule is inserted and chemically linked by transesterification into a cosmetic oil provided with functionalities which are suitable for the chemical anchoring of the molecule and chemically linked to said oil. The cosmetic oil may be a silicone macrodiol functionalized with a photochromic derivative designed so as to ensure the transition between a colorless state and a colored state following irradiation with ultraviolet light.

Solid pigment dispersions are described which are formulated to a paste consistency during grinding to reduce the pigment particle size and form a dry granular consistency at ambient temperature that is pourable and easy to handle. This allows for stronger, more intense colors and allows for easy integration into a variety cosmetic products. These pigment dispersions are prepared with plant-derived substances, derived from naturally occurring, renewable sources.

The invention relates to a cosmetic composition comprising, in a physiologically acceptable medium, an oily phase and at least a) a phenyl silicone oil of formula (I) [Chem 1] (I) wherein —Me is methyl and Ph is phenyl, OR′ represents an —OSiMe3 group, —y ranges from 1 to 1000, and —z ranges from 1 to 1000, b) a C8-C30 fatty alcohol, c) a branched dextrin ester, and d) advantageously a liposoluble polymer selected from among the group consisting of: (i) acrylate polymers selected from among the group consisting of silicone acrylate polymers, acrylate polymers comprising an alkyl chain of at least 10 carbon atoms, and copolymers of acrylates and acrylamide, (ii) copolymers of vinylpyrrolidone (VP) and alkene comprising at least 18 carbon atoms, and (iii) mixtures thereof, and its use in particular on the lips for a make-up result with improved gloss and longer-lasting gloss and color. Preferably, the composition is in a semi-solid or solid form.

The present invention relates to a composition, notably a cosmetic composition, in particular for making up and/or caring for keratin materials, comprising at least retinol, di-t-butyl pentaerythrityl tetrahydroxycinnamate and an ethylenediaminedisuccinic acid salt.
