Description

Technical Field

[0001] The present disclosure relates to a makeup cosmetic composition for the skin, and more particularly, to a fluid foundation that can impart improved color characteristics (color fidelity and stability) to the skin without impairing the retention (non-transferability).

Background Art

[0002] Makeup compositions for the skin, specifically foundations, have been used for many years, particularly to reduce the visual and / or tactile irregularities of the skin and improve the aesthetic appearance of the skin. Today, consumers are looking for lighter, more comfortable galenics (carrier-based) that have a natural makeup effect and do not compromise the makeup result (while being covering yet natural) and retention (preferably retained for 24 hours). From the prior art, it is known to use water-in-oil emulsions containing silicone oil and hydrophobic treated pigments for good adhesion to the skin, and film-forming polymers to improve the retention of the deposits. However, there remains a need to develop novel compositions having improved color characteristics (color fidelity and stability) without impairing the retention (non-transferability).

[0003] The applicant has appropriately demonstrated that in a water-in-oil emulsion containing two different silicone acrylate polymers, a volatile oil, and a pigment treated with a hydrophobizing agent, C 8-22 By using alkyldimethicone, particularly cetyl dimethicone, the above requirements can be appropriately met.

Summary of the Invention

Means for Solving the Problems

[0004] A first object of the present disclosure is a makeup cosmetic composition for use on keratinous substances, particularly the skin, which is in the form of a water-in-oil emulsion and contains, in a physiologically acceptable medium, at least the following components: a) A vinyl polymer having at least one unit derived from a carbosiloxane dendrimer, b) A silicone acrylate polymer different from compound a), c) One or more volatile oils, d) C 8-22 Alkyl dimethicone, and e) A colorant surface-treated with a hydrophobizing agent To provide a makeup cosmetic composition containing the same.

[0005] The "vinyl polymer having at least one unit derived from a carbosiloxane dendrimer" means that the vinyl polymer has a molecular side chain containing a carbosiloxane dendrimer structure.

[0006] The present disclosure also relates to a makeup method for keratinous substances, particularly for the skin, preferably the skin of the face and / or neck, which comprises applying at least one of the cosmetic compositions defined by the present disclosure onto the keratinous substances.

The color after 6 - 8 hours is required to be as faithful as possible to the color after application, in other words, to have little color change over time. This is also referred to as "color fidelity" or "color stability over time".

Example

[0118] Example: C on the Influence on Color Fidelity and Stability over Time 8-22 Selection of Alkyl Dimethicone

[0119] Preparation of Composition Prepare a water droplet type emulsion in silicone with the following composition:

[0120] [Table 1]

[0121] The above composition is obtained by the following preparation method: Mix Component A1, then add Component A2 which has been pre - pulverized, and then add Component A3; Mix Components B1, B2 and B3; Mix Phase B into Phase A while stirring until a homogeneous emulsion is obtained.

[0122] Evaluation of the Effect of Dispersants on Color Fidelity and Stability The following two dispersants were tested: Cetyl dimethicone (ABIL® Wax9840) and Lauryl PEG - 10 tris(trimethylsiloxy)silylethyldimethicone (Dowsil ES5300), each tested at 0.5% by mass based on the total weight of the composition, and the evaluation of the two formulations was compared with a control formulation (without adding a dispersant, replaced with 0.5% of methyltrimicone). Composition 1 (invention example): Use 0.5% cetyl dimethicone (ABIL® Wax9840) Composition 2 (reference example): Without cetyl dimethicone Composition 3 (comparative example): Use 0.5% lauryl PEG - 10 tris(trimethylsiloxy)silylethyldimethicone

[0123] For the above three compositions, they were evaluated and compared in pairs of two on half of the face according to the following protocol by a panel of color experts. The application of the products was done on half of the face by a cosmetics expert using a brush, and the following observations were made: · Observation of the color of the bulk under the slide (corresponding to the color at the pump outlet) · Observation of the color after application to the facial skin (after 5 to 30 minutes) · Observation of the color change over time (after 2 hours and 6 hours)

[0124] The above tests were carried out on the absolute values of skin based on a moisturizing cream and without powder. The evaluation was carried out using VISIA-CR from the front and the left side face of the face in the visualization mode (with eyes closed). Photos were taken at the time of application (5 minutes later, immediately after application), 15 minutes later, 2 hours later, and 6 hours later.

[0125] The panel of experts evaluated two criteria: · Compared the "color placement" at the time of application with the makeup result (color) after application. Clear results are generally obtained between 5 and 30 minutes (here, evaluated at 5 minutes and 15 minutes after application). The color after application is required to be as faithful as possible to the color at the pump outlet (color of the bulk). Refer to the "color fidelity" at the time of application. Compared the "color change" over time corresponding to the color change in one day (here, evaluated at 2 hours and 6 hours later). The color after 6 hours is required to be as faithful as possible to the color after application, in other words, the color change over time is small. Also referred to as "color fidelity" or "color stability over time".

[0126] The results are shown in the following table:

[0127]

Table 2

[0128] These results show that the cetyl dimethicone in Composition 1 according to the present disclosure (C 8-22By (alkyl dimethicone), it has been shown that better performance can be obtained in terms of color fidelity after application and color stability over time compared to Composition 2 (reference) without a dispersant (the color fades after application and over time) or Composition 3 (comparative example) containing another dispersant (the color becomes more yellow after application and over time).

[0129] That is, the use of cetyl dimethicone in the composition according to the present disclosure enables better dispersion of pigments surface-treated with a hydrophobic treatment agent, and by combining two silicone acrylate polymers, high color fidelity and stable makeup results (color) over time can be achieved while maintaining non-transferability of the composition.
