AI Technical Summary

Problems solved by technology

However, lipstick formulations (whether the formulation is solid or liquid) are usually anhydrous and, for example, the introduction of active agents such as glycerin is the cause of stability problems of the composition (exudation)
The introduction of water into the standard framework caused problems with the instability of the composition over time (ie, the composition showed phase separation or bleeding)

Embodiment approach

[0094] According to a first embodiment, the non-volatile silicone oil is a nonphenyl silicone oil.

[0095] Non-volatile non-phenyl silicone oils may be selected from:

[0096] - non-volatile polydimethylsiloxane (PDMS);

[0097] - PDMS containing alkyl or alkoxy groups pendant and / or or located at the end of the silicone chain, these groups each containing 2 to 24 carbon atoms;

[0098] - PDMS comprising aliphatic and / or aromatic groups, or functional groups such as hydroxyl, thiol and / or amine groups;

[0099] - Polyalkylmethylsiloxanes optionally substituted with fluorine groups, such as polymethyltrifluoropropyldimethylsiloxane;

[0100] - polyalkylmethylsiloxanes substituted by functional groups such as hydroxyl, thiol and / or amine groups;

[0101] - Polysiloxanes modified with fatty acids, fatty alcohols or polyoxyalkylenes, and mixtures thereof.

[0102] According to one embodiment, the composition according to the invention comprises at least one non-phenyl silicon...

no. 1 approach

[0407] According to a first embodiment, the composition comprises at least one hydrocarbon-based surfactant.

[0408] Examples of hydrocarbon-based surfactants suitable for use in the present invention are described below.

[0409] According to a particularly preferred embodiment, as seen above, the composition according to the invention comprises at least one surfactant selected from the group consisting of anionic and nonionic surfactants, at least partly through The aqueous dispersion of alkylcellulose used during the preparation of the composition of the invention is introduced.

[0410] nonionic surfactant

[0411] The nonionic surfactants may be chosen especially from the group consisting of alkyl esters of polyethylene oxide and polyalkyl esters of polyethylene oxide, oxyalkylenated alcohols, alkyl ethers of polyethylene oxide and polyalkyl ethers of polyethylene oxide, optionally polyoxyethylated alkyl esters of sorbitan and optionally polyoxyethylated polyalkyl este...

[0828] Preparation scheme

[0829] 1) Mix an aqueous dispersion of ethyl cellulose with a fixed oil while stirring, and heat the mixture at 55°C for 1 to 2 hours.

[0830] 2) Add surfactant (for Example 1) and stir the mixture at 55°C until homogeneous.

[0831] 3) Add polyvinyl alcohol until a homogeneous mixture is obtained, and the resulting mixture is cooled to room temperature.

[0832] 4) Then add non-volatile silicone oil, while stirring continuously.

[0833] 5) Then add the dye / pigment pre-dissolved in water.

[0834] 6) Finally, add ethanol and phenoxyethanol while stirring.

[0835] Evaluation of cosmetic properties: gloss, migration resistance

[0836] Gloss and migration were assessed in vivo by Chromasphere SEI-M-02232-CHRO-0 as described in patent application FR2829344.

[0837] Gloss was evaluated immediately after application of the formulations and...

Abstract

The present invention relates to a cosmetic composition comprising, in a physiologically acceptable medium, at least water, at least alkylcellulose, at least a first nonvolatile oil chosen from silicone oils and / or fluoro oils, and at least a second hydrocarbon-based nonvolatile oil chosen from C10-C26 alcohols, preferably monoalcohols; monoesters, dieters or triesters of a C2-C8 monocarboxylic or polycarboxylic acid and of a C2-C8 alcohol, which are optionally hydroxylated; and polyesters of a C2-C8 polyol and of one or more C2-C8 carboxylic acids.

Description

technical field [0001] The object of the present invention is to provide cosmetic compositions comprising alkyl cellulose, in particular for making up and / or caring for the lips or the skin, especially the lips, capable of producing deposits, especially is a cosmetic deposit that has good cosmetic properties, especially in terms of gloss, comfort and non-stickiness. [0002] More specifically, the compositions targeted according to the invention are aqueous compositions, which are particularly appreciated for formulating water-soluble colorants. Background technique [0003] In general, cosmetic compositions need to impart aesthetics when applied to the skin and / or lips, as well as sustain this aesthetic over time. [0004] In fact, the aesthetic feeling produced after application of a cosmetic composition results from the combination of properties inherent in the composition, such as cosmetic properties, cosmetic properties such as ease of application, finesse of makeup, u...
