Abstract
Description
[0001] Composition comprising spiculisporic acid or its salts, an oil and a filler
[0002] The present invention relates to a composition, in particular a cosmetic composition, specifically for the care of keratinous materials, comprising, in a physiologically acceptable medium:
[0003] a) at least one compound of formula (I) and / or (I’), and / or their stereoisomers, and / or their salts, and / or their solvates, such as hydrates:
[0004]
[0005] in which R’ represents a linear or branched, cyclic or acyclic, saturated or unsaturated group, comprising 1 to 20 carbon atoms, and M+represents a cationic counter-ion, b) at least one oil, and
[0006] c) at least one filler.
[0007] Emulsions, specifically oil-in-water (O / W), are well known in the field of cosmetics, particularly for the preparation of products such as milks, creams, tonics and serums.
[0008] In this type of composition, it is common to use fillers, specifically to improve the sensoriality of these compositions or to give them a care aspect. For example, acne products often comprise fillers to reduce seborrhea by absorbing sebum.
[0009] Fillers can also add desired optical properties to this type of composition, such as mattness (i.e. reducing the glossy aspect of the skin) and / or a blurring effect (i.e. masking skin imperfections by diffusing light homogeneously).
[0010] However, the presence of filler results in decreased hydration provided by these compositions. A solution to remedy this hydration decrease is to increase the humectant content, but this then entails an undesirable sticky sensation.
[0011] There is therefore a need for compositions that are moisturizing in the presence of fillers, while remaining cosmetically pleasant to use, that is, in particular, which do not produce a sticky effect.
[0012] The inventors have now discovered that the mixing of a compound of formula (I) and / or (I’), specifically spiculisporic acid, with at least one oil makes it possible to obtain acomposition which, although comprising fillers, is moisturizing and non-sticky upon application.
[0013] Moreover, the formulation of environmentally friendly cosmetic products, that is, those whose design and development take into account environmental issues, is becoming a major concern, to help address global challenges.
[0014] It is therefore essential to propose more sustainable compositions and / or preparation processes and / or ingredients, thus making it possible to respond to these environmental issues.
[0015] In this context, it is important to develop new cosmetic compositions with a better carbon footprint, specifically by promoting the use of renewable raw materials and / or with a good naturalness index and / or of natural origin and, more particularly, of plant origin, while reducing and / or eliminating the use of petrochemical compounds.
[0016] Thus, the present invention aims at a composition, in particular a cosmetic composition, specifically for the care of keratinous materials, comprising, in a physiologically acceptable medium:
[0017] a) at least one compound of formula (I) and / or (I’), and / or their stereoisomers, and / or their salts, and / or their solvates, such as hydrates:
[0018]
[0019] wherein R’ represents a linear or branched, cyclic or acyclic, saturated or unsaturated group, comprising 1 to 20 carbon atoms, and M+represents a cationic counter-ion, b) at least one oil, and
[0020] c) at least one filler.
[0021] "Physiologically acceptable" means a medium compatible with keratinous materials.
[0022] It also aims at a cosmetic process for the care of keratinous materials, preferably the skin, wherein the composition according to the invention is applied to said keratinous materials.The invention also aims at the use of the composition according to the invention to moisturize keratinous materials on which the composition is applied.

[0139] EXAMPLES
[0140] Example 1 :
[0141] The composition C3 according to the invention and the comparative compositions C1*, C2*, and C4* of Tables 1 and 2 below are prepared according to the following protocol:- Dissolve spiculisporic acid in the organic base in the presence of water at room temperature, with a magnetic stirrer;
[0142] - Add glyceryl caprylate or glyceryl stearate and citrate to the previous mixture under magnetic stirrer agitation at room temperature or solubilization temperature of the surfactant;
[0143] - Add glycols under magnetic stirrer agitation at room temperature;
[0144] - Add oils to the previous mixture under rotor-stator agitation at 2000 rpm for 10 minutes at room temperature;
[0145] - Add the gelling agent to the emulsion under rotor-stator agitation at 2000 rpm at room temperature;
[0146] - Add the remaining water with solubilized actives and preservatives, then fillers and ethanol under rotor-stator agitation at 2500 rpm at room temperature.
[0147] [Table 1]
[0148]
[0149] [Table 2]
[0150]
[0151]
[0152] These compositions were tested by corneometry, which makes it possible to evaluate their effect on the hydration level of the upper layers of the skin by repeated measurements of its dielectric capacitance, after single or repeated skin application, with an untreated area serving as a control.
[0153] The hydration rate measurements are carried out using a CORNEOMETER® CM 825 PC CORNEOMETER (COURAGE + KHAZAKA).
[0154] The 2mg / cm2application is done with a finger cot, then massaged with the fingertip until complete penetration. Complete penetration is considered to be when a drag sensation appears. The waiting time before measurement is 1 hour, and 3 wipes are performed before measurement.
[0155] The test was conducted on 4 volunteers.
[0156] The C4* formula serves as a positive reference for this test, and a bare skin area serves as a negative reference.
[0157] The results obtained are as follows:
[0158] [Table 3]
[0159]
[0160] These results show that the combination of spiculisporic acid with one or more oils (preferably isopropyl stearate, caprylic / capric triglycerides and dicaprylyl ether) in the presence of a low glycerin content (5%) makes possible a hydration level significantly higher than the hydration reference C4* that contains 7% glycerin. The addition of 1.5% fillers to the mixture (composition C3) makes it possible to maintain a hydration level higher than the hydration reference C4* that contains 7% glycerin.
[0161] Example 2:
[0162] The compositions C5 and C6 according to the invention and the comparative compositions 07* and C8* of Tables 4 and 5 below are prepared using a similar protocol to example 1.
[0163] [Table 4]
[0164]
[0165] [Table 5]
[0166]
[0167] These compositions were tested by the following protocols.
[0168] To measure gloss at 60°, a 30 pm thick film of each composition was formed on an uncoated contrast card using a film applicator, then oven-dried at 37°C for24h. Three gloss measurements are then taken using a glossmeter.
[0169] To measure Haze, a 25.4pm thick film was formed on a transparent plastic film (Byk) using a film spreader, then oven-dried at 37°C for 5 minutes. Three haze measurements are then taken using a Hazegard.The results obtained are as follows:
[0170] [Table 6]
[0171]
[0172] As can be seen from these results, the combination of spiculisporic acid with fillers of various types (combination of silica and starch or starch alone) leads to an improvement of the mattness (or a reduction of the gloss) of the composition, as well as an improvement of the blurring properties (quantified by the haze).
