Description

Technical Field

[0001] The present invention aims to provide a novel anhydrous composition for the care and / or makeup of keratin materials, in particular the skin, comprising a) an oily phase comprising i) at least one volatile hydrocarbon oil and ii) dodecamethylpentasiloxane, and b) at least one silicone elastomer having carboxylic acid functional groups.

[0002] Cosmetic compositions are generally used to impart an aesthetically pleasing color to keratin materials such as the skin, but also to enhance the beauty of irregular skin by being able to hide marks and dyschromias, and to reduce the visibility of relief imperfections such as pores and wrinkles, and also spots and acne scars.

[0003] Applying cosmetic compositions such as foundations is the most effective way to enhance the beauty of the skin and reduce the visibility of uneven imperfections. In this regard, coverage is one of the main properties sought. In these compositions, pigments based on metal oxides such as iron oxide and titanium oxide are generally used in large quantities (combined with particles known as fillers that have a blurring or soft-focus effect). However, these compositions have a tendency to accumulate in uneven areas such as pores and wrinkles, resulting in uneven deposits on the skin, highlighting imperfections and creating a matte appearance on the skin that is considered unnatural.

[0004] Consumers seek products for caring for and / or making up keratin materials, in particular the skin, which exhibit a texture that is pleasant both at the sensory level and upon application, and in particular are easy to take and spread over the area of keratin material to be covered.

[0005] Cosmetic compositions based on silicone elastomers with carboxylic acid functional groups have been proposed in publications WO 2015066161 (US 20160200876), WO 2015066165, WO 2015066199, WO 2015167963, WO 20180165434 (US 10918587 B2), IPCOM000250448D, and IPCOM000250657D, which exhibit good performance qualities in terms of wear characteristics and durability. However, these polymers often exhibit a texture that is difficult to handle and apply, and tend to produce cosmetic compositions that lack fluidity, suppleness, and uniform consistency, preventing the product from being easily absorbed and spreadable on the skin.

[0006] One of the objects of the present invention is to produce a care and / or cosmetic composition comprising at least one silicone elastomer having carboxylic acid functional groups, which composition has sufficient fluidity, smoothness, flexibility and uniform consistency to be taken up and spread easily on the skin.

[0007] In the course of its investigations, the Applicant Company has surprisingly discovered that these aims can be achieved by an anhydrous composition for caring for and / or making up keratin materials, in particular the skin, comprising, preferably in a physiologically acceptable medium:

[0008] a) an oily phase comprising

[0009] i) at least one volatile hydrocarbon oil H1, and

[0010] ii) dodecamethylpentasiloxane; and

[0011] b) at least one silicone elastomer having carboxylic acid functional groups.

[0012] This discovery forms the basis of the present invention.

[0016] ii) dodecamethylpentasiloxane; and

[0223] Example 1 (present invention) and Examples 2 to 4 (outside the present invention)

[0224] The following compositions were prepared.

[0225] [Table 1]

[0226]

[0227] program

[0228] Use from VMI or Olsa A 400 nm reactor was used to produce Formulations 1 to 10. An ice bath was placed under the beaker to maintain the manufacturing temperature below 20°C.

[0229] The silicone elastomer is pre-dispersed under shear. The remaining ingredients are then gradually added to the elastomer until a homogeneous composition is obtained. The formulation is then freed from air bubbles under a vacuum hood.

[0230] Rheological analysis

[0231] In the controlled stress rheometer (RheoStress Rheological measurements were performed on each of Examples 1 to 7 at a Haake company. The shear stress and rate gradient measurements were performed using a conical sensor (C35 / 2° Ti L; 222-1871; 35 mm diameter, 2° angle) with a gap of 0.105 mm and a measuring plate (MPC 35; 222-1549; 35 mm diameter, sandblasted).

[0232] The gap temperature was controlled using an Eheim Pro 3600 / 2075020 hydraulic circulation pump and a Haake Universal Temperature Controler System (UTC) 6001 temperature control system.

[0233] During the measurement, an evaporation bell jar was placed above the cone and plate plane.

[0234] The gap temperature was set to 25° C. ± 0.5° C. Before each measurement, a 120-second constant temperature was applied at this temperature.

[0235] An upward oscillatory curve with amplitude sweep was applied, with a stress rise range of 10 -3to 10 3 Pa, the frequency is set to 1 Hz with a fixed phase of 50.

[0236] The rheological data of the seven formulations are described in the table below.

[0237] [Table 2]

[0238]

[0239]

[0240] Since the viscosity is not constant regardless of the value of the rate gradient, the compositions of Examples 1 to 4 are non-Newtonian (non-ideal) fluids. Rheological Herschel-Bulkley modeling of the equation:

[0241] [Mathematical formula 1]

[0242] T=T0+k(γ) n

[0243] Applied to the rheological curves of the investigated formulations 1 to 4: this leads to the correlation r 2 >0.995.

[0244] For non-ideal fluids, certain parameters are determined:

[0245] - The shape of the curve shows more or less shear-thinning properties (characterized by the exponent n obtained by modeling)

[0246] - Yield point T0 (from which the formulation begins to flow and its viscosity decreases)

[0247] -Coefficient of consistency k

[0248] -Viscosity changes with rate gradient.

[0249] The values of yield point T0, consistency coefficient k, and viscosity obtained with Example 1 of the present invention containing dodecamethylpentasiloxane are significantly lower than those obtained with Example 2 outside the present invention without volatile silicone oil, Example 3 outside the present invention containing cyclic silicone oil cyclopentasiloxane, and Example 4 containing dimethylpolysiloxane 6 cSt. These results show that Example 1 of the present invention exhibits a more fluid texture, making it easy to pick up and spread on the skin.
