Problems solved by technology

However, the introduction of gelling agents (especially AMPS-based polymers) can lead to the formation of a solid residue on the skin during application to the skin and after evaporation of the volatile compounds of the composition, a phenomenon also known as "peeling", thereby Causes annoying and unsightly effects when applied to the skin

Embodiment approach

[0132] According to one embodiment, the composition according to the invention comprises at least one gelling agent selected from:

[0133] - polymers derived from AMPS and copolymers of AMPS, especially acrylamide / AMPS copolymers, especially crosslinked anionic acrylamide / AMPS copolymers as described above;

[0134] - an acrylate-based copolymer derived from at least one C 3 -C 6 Polymerization of monoethylenically unsaturated carboxylic acid monomers or their anhydrides and at least one fatty chain acrylate monomer, such as described above, and which is optionally crosslinked, in particular acrylate / (C 10 -C 30 ) alkyl acrylate copolymer;

[0135] - and mixtures thereof.

[0136] According to a particular embodiment, the composition according to the invention comprises at least one first gelling agent selected from acrylamide / AMPS copolymers and at least one second gelling agent, in particular Crosslinked anionic acrylamide / AMPS copolymer as described above, said second...

Embodiment 1

[0264] Prepare the following emulsions:

[0265]

[0266]

[0267] operate:

[0268] The components of phase A on the one hand and the components of B on the other hand are mixed and each mixture is heated at 50-75° C. until a homogeneous mixture is obtained. Then, add phase A to phase B while stirring for 15 minutes, then cool to 40°C, add phases C, D and E with stirring, and then allow the mixture to return to room temperature.

[0269] The composition has a viscosity of 608 mPa.s, measured according to the method indicated above.

Embodiment 2 and 3

[0271] Prepare the following emulsions:

[0272]

[0273]

[0274] The composition of Example 2 has a viscosity of 2.07 Pa.s, measured according to the method indicated above (spindle No. 3).

[0275] Each emulsion was evaluated by 6 experts according to the following method:

[0276] Weigh 0.2 g of the composition to be tested and apply the composition by hand with 20 circular movements to the top of the other hand and then visually assess the appearance of the skin before the cream is absorbed.

[0277] Allow to dry for 2 minutes until the cream is absorbed, using circular motions on the hand area until the first flakes appear.

[0278] The composition of example 3 showed peeling at the end of 20 circular movements before being absorbed into the skin, while composition 2 according to the invention showed no peeling at the end of 20 circular movements.

[0279] These examples demonstrate that the presence of the oxyalkylenated derivatives according to the invention ma...

Abstract

The present invention relates to a cosmetic composition containing alkylene oxide derivants, concretely relates to a composition used for localized application containing thickening agents and especial alkylene oxide derivants.

Description

technical field [0001] The present invention relates to a composition comprising a thickener and an oxyalkylenated derivative. Background technique [0002] For various reasons especially related to a more comfortable application (softening, emollient effect, etc.), current cosmetic compositions comprise an aqueous phase and one or more oils and are, for example, of the oil-in-water (O / W) type Emulsions consist of an aqueous dispersed continuous phase and an oily dispersed discontinuous phase together with surfactants. [0003] In cosmetics, these compositions are especially studied due to the fact that they contain an aqueous phase as the external phase, which, when applied to the skin, gives the composition a fresher, less greasy and lighter texture than W / O emulsions. Feel. [0004] In order to thicken these compositions and give them the desired viscosity, thickeners or gelling agents are used. However, the introduction of gelling agents (especially AMPS-based polymer...
