Description

Description Title of the invention: Anhydrous cosmetic composition with a volatile hydrocarbon oil, dodecapentamethylsiloxane and a silicone elastomer with carboxylic acid functions. Technical field

[0001] = The present invention aims to propose for the field of care and / or makeup keratin materials, particularly skin, a new anhydrous composition comprising a) an oily phase comprising i) at least one hydro- volatile oil carbonaceous and ii) dodecapentamethylsiloxane and b) at least one silicone elastomer with carboxylic acid functions.

[0002] — Cosmetic makeup compositions are commonly used for bring an aesthetic color to keratin materials such as skin, but also to beautify uneven skin by hiding spots and dys- chromics, to reduce the visibility of relicf imperfections such as pores and wrinkles as well as pimples and acne marks.

[0003] = The application of a makeup composition such as a foundation is the most effective approach to beautify skin and reduce the visibility of imper- relief imperfections. In this respect, coverage is one of the main properties re- sought. In general, large quantities of these compositions are used pigments based on metal oxides such as iron oxides and titanium oxides associated with particles called charges having a blurring or soft focus effect. However, these compositions tend to accumulate in reliefs such as pores and wrinkles, leading to an uneven deposit on the skin by marking the im- perfections and giving a matte finish perceived as unnatural on the skin.

[0004] They also look for skincare and / or makeup products made from materials Keratins, especially skin which have a comfortable texture at the level sensory and application in particular which are easily sampled and spread easily on the area of ​​keratin material to be covered.

[0005] It has already been proposed, in published documents WO2015066161 (US20160200876), WO2015066165, WO2015066199, WO2015167963, WO20180165434 (US10918587B2), IPCOM000250448D, IPCOM000250657D, compositions of makeup based on silicone elastomers with carboxylic acid functions exhibiting good performance in terms of hold and durability. However, these polymers generally have a texture that is difficult to pick up and apply and have tendency to produce makeup compositions with insufficient consistency fluid, flexible and homogeneous does not allow the product to be easily taken and spread on the skin. One of the objectives of this invention is to produce a care and / or makeup composition comprising at least one silicone elastomer with carboxylic acid functions having a sufficiently fluid, smooth, flexible and homogeneous consistency to be taken and easily spread on the skin. During its research, the applicant unexpectedly discovered that these objectives could be achieved with an anhydrous composition for the care and / or makeup of keratin materials, in particular the skin, comprising, preferably in a physiologically acceptable medium: a) an oily phase comprising 1) at least one volatile hydrocarbon oil H, and 11) dodecamethylpentasiloxane; and b) at least one silicone elastomer with carboxylic acid functions. This discovery is the basis of the invention. The present invention relates to an anhydrous composition for the care and / or makeup of keratin materials, in particular the skin, comprising, preferably in a physiologically acceptable medium: a) an oily phase comprising 1) at least one volatile hydrocarbon oil H, and 11) dodecamethylpentasiloxane; and b) at least one silicone elastomer with carboxylic acid functions. The invention also relates to a process for coating keratin materials, more particularly for making up and / or caring for keratin materials, such as the skin, characterized in that it comprises the application to the keratin materials of an emulsion as defined above. The invention relates more particularly to a process for making up and / or caring for the skin, characterized in that it comprises the application to the skin of a composition as defined above. Definitions In the context of the present invention, by “keratin materials” is meant the skin and more particularly areas such as the face, cheeks, hands, body, legs and thighs, the eye contour, the eyelids. By "physiologically acceptable" we mean compatible with the skin and / or its appendages, which has a pleasant color, odor and feel and which does not generate unacceptable discomfort (tingling, tightness) likely to discourage the consumer from using this composition. For the purposes of the present invention, the term "anhydrous" means a composition comprising a content of less than or equal to 2% by weight of water, preferably in- less than or equal to 1%, more preferably less than 0.5% by weight relative to the total weight of said composition or even free of water.

An ice bath was placed under the beaker to maintain a manufacturing temperature below 20°C. The silicone elastomer was pre-dispersed under shear. The remaining ingredients were then gradually added to the elastomer until a homogeneous composition was obtained. The formula was then de-bubbled under a vacuum bell. Rheological analyses Rheological measurements were carried out on each of examples 1 to 7 in an imposed stress rheometer (RheoStress 600®, Haake). Stress measurements Shear and velocity gradient measurements were performed using a cone sensor (C35 / 2° Ti L; 222-1871; 35 mm diameter, 2° angle), with a 0.105 mm air gap and a measuring plane (MPC 35; 222-1549; 35 mm diameter, sandblasted). The air gap temperature was controlled using an Eheim Pro 3600 / 2075020 hydraulic circulation pump and a Haake Universal Temperature Controller System (UTC) 6001. An anti-evaporation bell was positioned above the cone plane and the plane during measurement. The air gap temperature is set at 25+0.5°C. A 120-second isotherm at this temperature is applied before each measurement. An ascending oscillation curve with an amplitude sweep was imposed with a stress ramp ranging from 10 to 10° Pa, with a frequency fixed at 1 Hz with 50 steps. The rheological data of the 7 formulas are described in the table below: [Tables2] Ex2 Ex3 Ex4 outside outside outside invention invention invention 20 20 20 5 0 60 [50 bone ps bone 280 250 200 0 = 0 jo jus po pe The 25 25 00 Jos 0.48 0.44 Since viscosity is not constant regardless of the value of the velocity gradient, the compositions of examples | to 4 are non-Newtonian (non-ideal) fluids. A Herschel-Bulkley rheological modeling of equation: [Math 1] T=T9+k(y}" was applied to the rheological curves of the formulas] at 4 studied: this resulted in a correlation 12 > 0.995. For non-ideal fluids, certain parameters have been identified: - the shape of the curve showed a more or less rheofluidifying character (characterized by the index n obtained by modeling) - the flow threshold tÔ (point from which the formulation has flowed and its viscosity has decreased) - the consistency factor k - viscosity as a function of the velocity gradient. The values ​​of the flow threshold Ty, of the consistency factor k as well as the viscosity values ​​obtained with example 1 of the invention comprising dodecamethylpentasiloxane are significantly lower than those obtained with example 2 outside the invention without volatile silicone oil, example 3 outside the invention comprising the cyclic silicone oil cyclopentasiloxane and example 4 comprising a 6-est dimethicone. These results showed that example 1 of the invention has a more fluid texture allowing it to be easily picked up and spread on the skin.
