Description

Title of the invention: NON-SOLID COSMETIC COMPOSITION WITH A HYDROCARBON OIL NON-POLAR VOLATILE, A SOLVENT HAVING AN ALCOHOL, ACID, AMINE OR AMIDE FUNCTION AND A SILICONE ELASTOMER HAVING CARBOXYLIC ACID FUNCTIONS. Technical field

[0001] The present invention aims to propose, for the field of care and / or makeup for keratinous materials, in particular the skin, a new non-solid composition comprising a) an oily phase comprising i) at least one volatile apolar oil based on hydrocarbons and ii) at least one liquid hydrocarbon solvent comprising at least one alcohol, acid, amine or amide function and b) at least one silicone elastomer containing carboxylic acid functions.

[0002] Cosmetic makeup compositions are commonly used to provide aesthetic color to keratinous materials such as skin, but also to beautify irregular skin by allowing to conceal spots and dyschromias, to reduce the visibility of relief imperfections such as pores and wrinkles as well as pimples and traces of acne.

[0003] It is also a question of seeking care and / or makeup products for keratinous materials, in particular for the skin, which have a comfortable texture at the sensory level and during application, in particular which are easy to remove and which spread easily over the area of ​​keratinous material to be covered.

[0004] Makeup compositions based on carboxylic acid-functional silicone elastomers with good performance in terms of hold and durability have already been proposed in published documents WO2015066161 (US20160200876), WO2015066165, WO2015066199, WO2015167963, WO20180165434 (US10918587B2), IPCOM000250448D, IPCOM000250657D. However, these polymers generally have a texture that is difficult to pick up and apply and tend to produce makeup compositions whose consistency does not allow the product to be easily picked up and spread on the skin.

[0005] One of the objectives of the present invention is to produce a care and / or makeup composition comprising at least one silicone elastomer with carboxylic acid functions which is stable, and having a suitable, flexible and homogeneous to be taken and easily spread on the keratinous material to be covered, in particular the skin.

[0006] During his research, the applicant unexpectedly discovered that this objective could be achieved with a non-solid composition for the care and / or makeup of keratinous materials, in particular the skin, comprising, preferably in a physiologically acceptable medium:

[0007] a) an oily phase comprising

[0008] i) at least one non-polar volatile hydrocarbon oil Hi and

[0009] ii) at least one liquid hydrocarbon solvent with a molecular mass of less than 600 g / mol comprising at least one alcohol, carboxylic acid, amine or amide function and mixtures thereof; provided that when the liquid hydrocarbon solvent is a primary alcohol, it comprises at least 3 carbon atoms, and

[0010] b) at least one silicone elastomer with a carboxylic acid function;

[0011] the weight ratio between the total quantity of volatile oil(s) and the total quantity of liquid hydrocarbon solvent(s) ii) being less than or equal to 20.0.

[0012] This discovery is the basis of the invention.

[0013] The present invention relates to a non-solid composition for the care and / or makeup of keratinous materials, in particular the skin, comprising, preferably in a physiologically acceptable medium:

[0014] a) an oily phase comprising

[0016] ii) at least one liquid hydrocarbon solvent with a molecular mass of less than 600 g / mol comprising at least one alcohol, carboxylic acid, amine or amide function and mixtures thereof; provided that when the liquid hydrocarbon solvent is a primary alcohol, it comprises at least 3 carbon atoms, and

[0017] b) at least one silicone elastomer with a carboxylic acid function;

[0018] the weight ratio between the total quantity of volatile oil(s) and the total quantity of liquid hydrocarbon solvent(s) ii) being less than or equal to 20.0.

[0024] The hardness measurements are carried out on the formulas obtained after manufacture, as is (finished products without packaging). The hardness of the formulas is measured after 24 hours of waiting at 25°C and 40% humidity. The jars containing the samples are characterized by texturometry using a texturometer such as TA.XTplus Texture Analyzer® marketed by the company Stable Micro Systems, according to the following protocol:

[0025] The hardness corresponds to the force required, in Newtons, for the punch to penetrate the composition by 2 mm. Depending on the shape of the products, the tests are repeated between 2 and 5 times per product. A P / 20 type punch (diameter 20 mm) is brought into contact with the sample at a speed of 1 mm / s. The measuring system detects the interface with the sample with a detection threshold equal to 0.02 Newtons. The probe is inserted 2 mm into the sample at a speed of 1 mm / s. The measuring device records the evolution of the force measured in compression over time, during the penetration phase. The hardness of the sample corresponds to the average of the maximum values ​​of the force detected during penetration, over 2 to 5 measurements. Oily phase

[0446] Operating mode:

[0447] Formulations 1 to 24 were made using a Triblab® or Olsa Minilab® type reactor from VMI. An ice bath was placed under the beaker to maintain the manufacturing temperature below 20°C.

[0448] The silicone elastomer was predispersed under shear. The remaining ingredients were then added to the elastomer little by little until a homogeneous composition was obtained. The formula was then de-bubbled under vacuum.

[0449] Rheological analysis under shear stress

[0450] Rheological measurements were carried out on each of Examples 1-10 in an imposed stress rheometer (RheoStress 600®, Haake). Shear stress and velocity gradient measurements are carried out using a cone sensor (C35 / 2° Ti L; 222-1871; diameter 35 mm, angle 2°), with an air gap of 0.105 mm and a measuring plane (MPC35; 222-1549; diameter 35 mm, sandblasted).

[0451] The air space temperature was regulated using an Eheim Pro 3600 / 2075020 hydraulic circulation pump and a Haake Universal Temperature Controller (UTC) 6001.

[0452] An anti-evaporation bell was positioned above the cone plane and the plane during the measurement.

[0453] The air space temperature was set at 25 ± 0.5 °C. A 120-second isotherm at this temperature was applied before each measurement.

[0454] An ascending oscillation curve with an amplitude sweep was imposed with a stress ramp from 10-3 to 103 Pa, with a frequency set at 1 Hz with 50 steps. Discussion and results

[0455] The rheological behavior of formulas 1 to 24 was analyzed. Measurements of the storage modulus G', the loss or dissipation modulus G” were used to determine the complex modulus G* as well as the phase shift ô between stress and strain. These data were analyzed as a function of shear stress.

[0456] The behavior of the rheological curves revealed that these were materials that only flowed if a sufficiently high stress was applied to them.

[0457] The value of the complex modulus G* at the plateau before the curve breaks gives us an idea of ​​the consistency of the product at rest.

[0458] The rheological data of formulas 1 to 24 are described in the tables below:

[0463] The results showed that Examples 2 to 10 and 19 to 22 of the invention comprising hydrocarbon solvents having an alcohol, carboxylic acid, amine or amide function and a molecular mass of less than 600 g / mol had a sufficiently flexible and homogeneous consistency to be taken and easily spread on the keratinous material to be covered, in particular the skin, unlike Example 1 outside the invention not containing this type of solvent and Examples 11 to 18 outside the invention comprising other types of hydrocarbon solvents having a molecular mass greater than 600 g / mol (castor oil), or comprising an ether, carbonate or ester function.

[0464] As observed in Examples 20-22 according to the invention comprising a primary alcohol comprising at least 3 carbon atoms, the consistency was increased compared to Example 19 comprising a primary alcohol comprising 2 carbon atoms.

[0465] The results also showed that Examples 23 and 24 outside the invention, in which the weight ratio of the total quantity of volatile oil(s) to the total quantity of liquid hydrocarbon solvent(s) ii) was strictly greater than 20.0, had a consistency too weak to be taken and easily spread on the keratinous material to be coated, in particular the skin.
