Problems solved by technology

However, such compositions are only partially removable by water and thus exhibit poor water washability
Furthermore, such compositions lack long-lasting cosmetic effects due to their hydrophilic nature

Embodiment approach

[0279] According to a preferred embodiment of the present invention, the composition is prepared according to the following steps:

[0280] 1) Add at least one third surfactant and at least one pigment as defined in the present invention to water, mix at room temperature (25° C.) until uniform, and obtain phase B;

[0281] 2) Mix at least one oil with phase B, mix by stirring for 15 minutes to obtain Emulsion 1, which is an oil-in-water emulsion;

[0282] 3) mixing at least two surfactants selected from:

[0283] i)C 8 -C 22 Alkyl dimethicone copolyols;

[0284] ii) dimethicone copolyols, which are different from i);

[0285] iii) polyoxyalkylene silicone elastomers, which are different from i) or ii);

[0286] iv) or mixtures thereof;

[0287] and / or at least one oil to obtain fatty phase A;

[0288] 4) Add the emulsion 1 obtained in step 2) to the fatty phase A obtained in step 3), and homogenize the mixture by stirring to form an oil-in-water-in-oil emulsion.

[0301]

[0302]

[0303]

[0304] Remark:

[0305] Formulation 1 according to the invention comprises a hydrophilic pigment;

[0306] Inventive formulation 2 comprises a hydrophobic pigment;

[0307] Comparative formulation 1 replaces the third surfactant according to the formulation 2 of the present invention with polyglyceryl caprate (4);

[0308] Compared to formulation 2 according to the invention, comparative formulation 2 does not contain the third surfactant.

[0309] The compositions listed above were prepared according to the following steps:

[0310] 1) At room temperature (25°C), mix the ingredients of phase B until uniform to obtain phase B;

[0311] 2) Add fatty phase A2 to phase B and homogenize by stirring for 15 minutes to obtain emulsion 1, which is an oil-in-water emulsion;

[0312] 3) At room temperature (25°C), mix the phase components until uniform to obtain the fa...

Abstract

A composition in form of an emulsion is provided, which comprising at least one fatty phase, at least one aqueous phase, and a)a combination of at least two surfactants chosen from the group consisting of: i)C 8-C 22 alkyl dimethicone copolyols; ii)dimethicone copolyols, which is different from i); iii) poly oxyalkylenated silicone elastomers, which is different from i) or ii); iv) or a mixture thereof; b)at least one third surfactant, different from the surfactant a),chosen from polydialkyl silicones containing polyglycerol or glycerol side and / or end groups; and c)at least one pigment.

Description

technical field [0001] The present invention relates to a composition, especially a cosmetic composition for the care / make-up of keratinous materials, especially the skin and lips, more especially of the emulsion type, which exhibits an optimized washability effect while maintaining a good make-up Effect. Background technique [0002] Cosmetic compositions for the care / makeup of keratinous materials, especially the skin and lips, more especially the skin, also known as foundations, concealer products or tinted creams, are usually used to impart an aesthetic color to the skin (e.g. the face) in order to conceal the skin Imperfections such as redness and blemishes. [0003] For centuries, consumers all over the world, especially in Asia, have sought novel cosmetic products for improving the appearance of keratinous materials (and especially skin), especially surface appearance (visible and / or tactile unevenness) and and / or skin complexion, which is an external sign of health...
