Water-free cosmetic composition containing plant oils

Description

TECHNICAL FIELD

[0001] The present invention relates to the field of compositions for the care of keratin materials comprising vegetable oils. CONTEXT

[0002] In recent years, cosmetic manufacturers have faced growing consumer demand for more natural and skin-friendly cosmetic products. A multitude of cosmetic compositions based on vegetable oils have been launched to meet this demand. Vegetable oils are renowned for their nourishing properties and are particularly appreciated by consumers due to their naturalness and multifunctionality. Indeed, these oils can be used on the face, body, and hair. There are many varieties of vegetable oils, each with different properties. However, a major drawback to using these oils is that they can sometimes feel too greasy and absorb too slowly when applied to the skin.Likewise, some of these oils may have too strong an odor for some users.

[0003] In order to overcome these various problems, the applicant tried to add alcohol to the vegetable oils in order to obtain a more fluid and lighter oily composition, with a dry feel, i.e. capable of penetrating quickly into the skin without leaving a greasy film, and having a limited olfactory impact. However, the oily compositions obtained after adding alcohol may be cloudy due to the immiscibility of the vegetable oils and the alcohol, which, in addition to being visually unattractive, may result in the oil not being distributed evenly on the skin or hair when applied.

[0004] Therefore, there is still a need for clear, fluid, light and dry-touch oil compositions.

[0005] Furthermore, there is a need for simple oily compositions with a limited number of ingredients, limited olfactory impact and respect for the environment. FR 1 271 011 discloses methods for solubilizing oils in low molecular weight alcohols and the use of these compositions in the field of cosmetics.

[0006] The applicant has unexpectedly and surprisingly discovered that all of these problems can be solved by the composition according to the present invention. SUMMARY

[0007] According to one aspect, the present invention relates to an anhydrous cosmetic composition comprising: (a) at least one vegetable oil in a total content by weight x between 10% and 40% relative to the total weight of the composition; and b) at least one C2-C4 monoalcohol, in a total content by weight ybetween 5% and 21% relative to the total weight of the composition; and c) at least one compound C different from the compounds constituting the vegetable oil, in a total content by weight z relative to the total weight of the composition, compound C having a calculated logP value less than or equal to 8.6, wherein: compound C is selected from the group consisting of liquid fatty acid esters, liquid fatty alcohol esters, liquid fatty alcohols and mixtures thereof; and the composition does not include fillers; and 90 % ≤ x + y + z ≤ 100 % ; And z ≥ 0,21 y − 0,56 x .

[0028] The expression "comprising" includes the expression "consisting of".

[0029] The expression "between ... and ..." must be understood inclusively. Anhydrous cosmetic composition

[0030] The subject of the present invention is an anhydrous cosmetic composition as defined above.

[0031] As explained above, the applicant added alcohol to the vegetable oils in order to obtain a more fluid and lighter oily composition, with a dry feel, i.e. capable of penetrating quickly into the skin without leaving a greasy film. However, since vegetable oils are poorly or not at all miscible in alcohol, the compositions obtained are cloudy, which, in addition to being visually unattractive, can result in non-uniform application of the oil to the skin or hair. The applicant surprisingly discovered that in order to obtain a transparent oily composition, it is necessary to add compound(s) C to the composition while respecting specific proportions between the content of vegetable oil(s), the content of C2-C4 monoalcohol(s) and the content of compound(s) C.

[0032] Such a composition is particularly interesting because it is very simple to prepare due to the small number of ingredients included in the composition.

[0033] The composition does not include fillers because fillers are not easily dispersible in an oily composition and do not allow a transparent composition to be obtained.

[0034] Preferably, 95% ≤ x + y + z ≤ 100%. More preferably, 97% ≤ x + y + z ≤ 100%.

[0035] Preferably, the composition may not comprise compounds selected from the group consisting of ether oxides, lipophilic gelling agents and mixtures thereof. Lipophilic gelling agents can in fact provide thickness to the composition, which is counterproductive to obtaining an oily composition with a dry feel.

[0036] An ether oxide is an organic compound of formula RO-R', where R and R' are alkyl groups. An example of an ether oxide is dicaprylyl ether.

[0037] Preferably, the composition may not comprise liquid fatty acid esters or liquid fatty alcohol esters other than compound C or liquid fatty acid esters other than those constituting the vegetable oil.

[0038] The calculated logP value of compound C may preferably be between 4.0 and 8.6, more preferably between 4.0 and 7.7.

[0039] Compound C can preferably be of plant origin. The addition of a compound C of plant origin makes it possible to obtain an oil composition that is even more environmentally friendly.

[0044] A liquid fatty alcohol ester of plant origin can, for example, be obtained by esterification of an acid and a fatty alcohol, the acid and / or the fatty alcohol being of plant origin. Liquid fatty acid monoesters and liquid fatty alcohol monoesters

[0045] Compound C may be selected from the group consisting of liquid fatty acid monoesters, liquid fatty alcohol monoesters and mixtures thereof.

R 1 may preferably represent a linear or branched alkyl radical comprising from 3 to 9 carbon atoms, more preferably from 5 to 9 carbon atoms.

[0047] The total number of carbon atoms included in the radicals R 1 and R 1 ' may preferably be between 8 and 22, more preferably between 9 and 18. Diesters and triesters

[0073] For each of the compositions, the vegetable oil is mixed with compound C (if present) in a syrup bottle using a magnetic stirrer at a temperature of 20 ± 5°C. Ethanol is then added to the bottle and the bottle is closed. Stirring is continued until a clear mixture is obtained. If after 10 min, a clear mixture is not obtained, stirring is stopped. Observations

[0074] In the table above, the symbol (-) indicates a visually cloudy mixture obtained during the preparation of the composition. The compositions for which a clear mixture is obtained are checked on D+1 (24 hours after the preparation of the composition) to ensure that the compositions are still stable and that no cloudiness appears in the composition. The symbol (+) indicates a visually clear mixture obtained during the preparation of the composition, which remains stable on D+1. The symbol (+ / -) indicates a visually clear mixture obtained during the preparation of the composition but not stable on D+1, with cloudiness beginning to form within the mixture. Conclusions

[0075] It has been found that the oily compositions according to the present invention (Examples 5 to 7, 9 to 22, 29, 31 to 33, 37 to 39) are clear. In addition, these compositions are fresh, fluid / light and have a weak oil odor.

[0076] It has also been found that the oily compositions having characteristics different from those according to the present invention (Examples 1 to 4, 8, 23 to 28, 30, 34 to 36, 40 to 43) are visually cloudy either during their preparation or on D+1.

[0077] The compositions of Examples 1 to 4, 27, 28, 30 and 34 to 36 are compositions whose total content by weight of compound C is lower than that of the present invention.

[0078] The compositions of Examples 40 to 43 comprise only vegetable oil and alcohol and do not comprise Compound C as defined in accordance with the present invention. The compositions of Examples 8, 23 and 24 comprise esters having a calculated logP that is different from that of Compound C as defined in accordance with the present invention. The composition of Example 25 comprises an ether oxide that is not Compound C as defined in accordance with the present invention. The composition of Example 26 comprises an alkane that is not Compound C as defined in accordance with the present invention.

[0079] Thus, when a composition does not comprise compound C as defined according to the present invention or in a content different from that defined according to the present invention, a visually cloudy mixture is obtained either immediately during the preparation of the composition or on D+1. Such a mixture may have the consequence that the oil may not be distributed uniformly on the skin or hair, during application of the composition.
