Description

Title of the invention: Cosmetic composition comprising a polar oil, an alkanol, a polyol, azelaic acid, and a low water content.

[0001] The invention relates to a composition, in particular a cosmetic composition, comprising:

[0002] - i) one or more polar oil(s) in an amount greater than 0.1% and less than or equal to 92% by weight relative to the total weight of the composition; - ii) one or more polyol(s) having from 2 to 20 carbon atoms; - iii) azelaic acid, one of its salts of organic or mineral bases, and its solvates or mixtures thereof; - iv) one or more alkanol(s) R-OH with R representing a linear or branched C2-C6 alkyl group; and it being understood that the composition comprises a quantity of water less than 8% by weight of water relative to the total weight of the composition.

[0003] The invention also relates to a method for treating keratin materials, in particular the skin of the face and / or body, comprising the application of said composition to said keratin materials.

[0004] The invention finally relates to the use of such a composition for the treatment of keratin materials, in particular for the care of the skin of the body and / or face.

[0005] In the cosmetic field of care, cosmetic compositions making it possible to obtain both good sensory properties and a care effect are increasingly sought after by users.

[0006] By “care effect” we mean, for example, an effect against the drying out or aging of keratin materials and in particular the skin, this care effect being provided by at least one active agent.

[0007] In this respect, azelaic acid proves to be interesting, in particular this compound is effective in treating skin care problems and in particular in combating skin irregularities such as acne, rosacea and / or wrinkles.

[0008] In addition, oily galenics are also increasingly sought after in the cosmetic field and more particularly in the field of skin care, in particular because they provide nutrition and a silky finish after application.

[0009] This type of galenic has notably been described in patent applications WO2018114850 A1 and WO2018114787 A1

[0010] However, azelaic acid has particular physicochemical properties which make it difficult to dissolve in composition and in particular in oily medium. It is therefore difficult to obtain stable cosmetic compositions, in particular oily galenics, containing azelaic acid.

[0011] Consequently, there remains a need for oily cosmetic compositions, in particular comprising oil(s) of natural or renewable origin, which are stable and which have good sensory properties such as feel after application and little change in odor over time.

[0012] Furthermore, the formulation of environmentally friendly cosmetic products, i.e. those whose design and development take environmental issues into account, is becoming a major concern to help meet global challenges.

[0013] It is therefore essential to offer more sustainable compositions that can respond to these environmental challenges.

[0014] In this context, it is important to develop new cosmetic compositions with a better carbon footprint, in particular by promoting the use of renewable raw materials and / or with a good index of naturalness and / or of natural origin and more particularly of plant origin while reducing the use of compounds of petrochemical origin.

[0015] We have surprisingly found that a composition, in particular a cosmetic composition, comprising: i) one or more polar oil(s) in a particular quantity, in particular greater than 0.1% by weight relative to the total weight of the composition; (ii) one or more polyol(s) having from 2 to 20 carbon atoms; (iii) azelaic acid, one of its salts of organic or inorganic bases and its solvates or mixtures thereof; iv) one or more alkanol(s) and a low water content, allows good stability properties to be obtained.

[0016] The oily composition according to the invention is preferably single-phase and transparent.

[0017] The composition according to the invention is stable. A composition is said to be stable when its macroscopic appearance (clarity and homogeneity) does not change after at least 24 hours (h) after preparation or manufacture.

[0018] Thus, the subject of the present invention is a cosmetic composition comprising: - i) one or more polar oil(s) in an amount greater than 0.1% and less than or equal to 92% by weight relative to the total weight of the composition; - ii) one or more polyol(s) having from 2 to 20 carbon atoms; - iii) azelaic acid, one of its organic or mineral base salts, and its solvated or their mixtures; - iv) one or more alkanol(s) R-OH with R representing a linear or branched C2-C6 alkyl group; and it being understood that the composition comprises a quantity of water less than 8% by weight of water relative to the total weight of the composition.

[0019] The composition according to the invention is in a particular mode intended for topical application, in particular on keratin materials, in particular the skin.

[0020] It comprises in particular a “cosmetically acceptable” medium also called a “physiologically acceptable” medium, that is to say a medium compatible with all keratin materials, in particular the skin.

[0021] For the purposes of the present invention, the term “keratin materials” means the skin and its appendages.

[0022] By “skin” we mean human skin, in particular of the face and / or body, the scalp.

[0023] By “annexes” is meant human keratin fibers, in particular eyelashes, eyebrows, nails, and hair, in particular eyelashes and hair.

[0024] The present invention also relates to a process for the cosmetic treatment of materials, characterized in that a composition in accordance with the present invention is applied to said keratin materials.

[0025] Furthermore, the invention also relates to the use of said composition in the cosmetic field, in particular for the care of the skin of the body or face.

[0026] Optionally, the composition according to the invention comprises an amount less than or equal to 7% by weight of one or more surfactants, preferably an amount less than or equal to 5% by weight of one or more surfactants, more preferably, an amount less than or equal to 3% by weight of one or more surfactants relative to the total weight of the composition. In a particular embodiment, the composition according to the invention comprises less than 1% by weight of one or more surfactants relative to the total weight of the composition, or even the composition is free of surfactants.

[0027] For the purposes of the present invention, the term "surfactant" means an amphiphilic molecule, that is to say that it has two parts of different polarity, in general one is lipophilic (soluble dispersible in an oily phase), the other is hydrophilic (soluble or dispersible in water).

[0028] Surfactants are characterized by their HLB (Hydrophilic Lipophilic Balance) value, HLB being the ratio between the hydrophilic part and the lipophilic part in the molecule. The term HLB is well known to those skilled in the art and is described for example in “The HLB System. A time-saving guide to Emulsifier Selection” (published by ICI Americas Inc; 1984). For emulsifying surfactants, the HLB generally ranges from 3 to 8 for the preparation of W / O emulsions and from 8 to 18 for the preparation of O / W emulsions. The HLB of the surfactant(s) used according to the invention can be determined by the GRIFFIN method or the DA VIES method.

[0029] Preferably, the composition according to the invention does not comprise emulsifying surfactants such as polyoxyethylenated castor oil, oxyethylenated or non-oxyethylenated sorbitol and / or sorbitan fatty acid esters such as polysorbates, phospholipids, polyethylene glycol and fatty acid esters such as PEG-15 stearate, as well as lecithin.

[0030] According to another preferred embodiment, the composition according to the invention does not comprise hydroxyethyl urea (hydroxyethyl urea), more preferably the composition does not comprise urea N-substituted on one or both nitrogen atoms, by one or two groups in particular chosen from (Cl-C6)alkyl optionally substituted by a hydroxy, better still the composition does not comprise N-substituted urea or unsubstituted urea.

[0032] In a first particular embodiment, the composition according to the invention comprises from 3% to 4% by weight of water relative to the total weight of the composition.

[0033] In a second particular embodiment, the composition according to the invention comprises from 0% to 1% by weight of water relative to the total weight of the composition, or even the composition is free of water.

[0034] The composition according to the invention is distinguished in particular from emulsions in that it is not in the form of a dispersion of two liquids which are immiscible with each other at room temperature (20°C-25°C). Indeed, the composition according to the invention does not have a dispersed phase (also called a discontinuous phase) in the form of droplets in a dispersing phase (also called a continuous phase). Macroscopic analysis (with the naked eye) of the composition according to the invention shows a clear, transparent and homogeneous appearance. In particular, the composition according to the invention has a clear and homogeneous appearance.

[0035] For the purposes of the present invention, the term “clear” means a composition presenting a “transparent” appearance and vice versa.

[0036] For the purposes of the present invention, the term “homogeneous” means a composition consisting of a single phase, in other words monophasic.

[0037] The transparency of the composition can be characterized visually and macroscopically using a conventional commercial test tube made of transparent, untinted glass, borosilicate, soda-lime or neutral glass such as Pyrex® or Duran® glass, 16 cm high and 1.6 cm in diameter, which is filled up to 14 cm of said tube (the bottom of the meniscus of the composition in the tube is 14 cm from the bottom of the tube). A published international application page (in A4 format) is placed behind at a distance of 1 cm; and by placing one's eyes at a distance (reading focal length relative to the test tube) of between 20 cm and 40 cm, such as 30 cm, and perpendicular to the middle of the composition of said tube (approximately 7 cm from the bottom of said tube), it is assessed whether one can clearly read through the composition in said tube, said page of the published international patent application, in particular the first page.It is understood that the tester sees correctly, or that he equips himself with glasses, lenses or any other optical devices that he normally uses to read. For example, we can use the application WO 2018 / 104428 and evaluate the sharpness, i.e. manage to read the 31 lines of page 13 to carry out the test or better do the reading test on the first page.

[0038] The transparency of the composition can also be characterized by measuring its transmittance. In the context of the present invention, the transmittance measurements are carried out at 25°C and at atmospheric pressure (1 atm) with a UV-Visible spectrophotometer, CARY Type 100 scan.

[0039] For the purposes of the present invention, the term “transparent composition” means a composition having a turbidity value of less than 200 NTU, preferably less than 150 NTU, preferably less than 100 NTU. Preferably, the turbidity of the compositions is at least equal to 1 NTU.

[0040] NTU (nephelometric turbidity units) are the units of measurement for the turbidity of a composition. The measurement of turbidity is carried out, for example, with a turbidimeter model 2100P from Hach Company, the tubes used for the measurement being referenced AR397A cat 24347-06. The measurements are carried out at room temperature (from 20°C to 25°C).

[0041] Preferably, the composition is transparent and has a turbidity value of between 1 and 200 NTU, preferably between 1 and 150 NTU, preferably less than 100 NTU.

[0042] According to a particular embodiment of the invention, the appearance of the composition (transparency) is evaluated visually and macroscopically.

[0043] The composition according to the invention is therefore neither opalescent, nor cloudy, nor opaque nor biphasic.

[0044] The macroscopic visual analysis of the composition according to the invention shows a transparent and single-phase appearance stable over time at room temperature, 4°C and 45°C.

[0045] In what follows, and unless otherwise indicated, the limits of a domain of values ​​are included in this domain, in particular in the expressions “between” and “ranging from ... to ...”.

[0046] Furthermore, the expression “at least one” used in the present description is equivalent to the expression “one or more”. i) Polar oil(s)
