Description

Title of the invention: Eye makeup composition based on trimethylheptane.

[0001] The present application relates to the technical field of cosmetics.

[0002] More specifically, the invention relates to an eye makeup composition comprising a volatile mixture of alkanes.

[0003] Even more specifically, the invention relates to a mascara composition or an eyeliner composition comprising a volatile mixture of alkanes.

[0004] Within the scope of this application, a number of definitions must be given.

[0005] An "alkane" is a saturated hydrocarbon consisting solely of carbon and hydrogen atoms linked together by simple covalent bonds, the general formula of which is CnH2n+2.

[0006] A "linear alkane" is an alkane in which each carbon atom is linked to a maximum of two carbon atoms.

[0007] A "branched alkane" is an alkane in which certain carbon atoms are linked to three or even four carbon atoms.

[0008] A "Cx alkane" is an alkane consisting of x carbon atoms, said alkane being able to be linear or branched. For example, dodecane is an alkane consisting of 12 carbon atoms or C12.

[0009] Commonly, a "volatile mixture of alkanes" is a mixture of alkanes having a flash point less than or equal to 95°C measured according to the ATSM D93 standard.

[0010] For the purposes of the present invention, the term “volatile mixture of alkanes” means a mixture of alkanes having a flash point less than or equal to 55°C measured according to the ATSM D93 standard.

[0011] The flash point measured according to ASTM D93 is called "flash point". The unit of the flash point measured according to ASTM D93 is the degree Celsius (°C). It can also be an average of values, each of the values ​​being obtained by means of a measurement according to ASTM D93.

[0012] The term "mass percentage" refers to the ratio of the mass of a first compound to the total mass of a mixture of compounds or composition, reduced to a percentage. For example, if 10 grams of a compound y are present in a mixture z having a total mass of 100 grams, then the mass percentage of y in z is 10%.

[0013] A “biosourced” compound or organic composition is defined as one in which the organic carbon present in the compound or composition is 100% of organic origin. plant (14C) by radiocarbon analysis according to one of the following standards ASTM D6866, EN 16640 or EN 16785-1.

[0014] The "naturalness index" of an organic composition is the percentage of organic carbon of plant origin (14C) determined by radiocarbon analysis according to one of the following standards: ASTM D6866, EN 16640 or EN 16785-1.

[0015] For the purposes of the present invention, the OECD 301F method makes it possible to assess the biodegradability of a substance by a manometric respirometry test.

[0016] Since the appearance of isododecane in cosmetics in the 1990s, its use has expanded considerably in all areas of cosmetics, from skin care products to makeup products such as mascara compositions, long-lasting lipstick, and hair products such as serums or anti-frizz dry oils.

[0017] In some of these products, isododecane can represent up to 60% by mass of the composition of these cosmetic formulas.

[0018] Long-lasting makeup now represents around 25% of the global makeup market: isododecane is a key component because it allows for long-lasting, transfer-free and water-resistant performance, while maintaining optimal comfort. This market was developed from this essential ingredient, isododecane, derived from petrochemicals

[0019] However, since oil resources are limited and the oil market is fluctuating and polluting, meeting the demand for isododecane or being able to provide at least equivalent properties in cosmetic formulations represents a strategic challenge for the cosmetics industry.

[0020] To address such a challenge, a first approach consists of developing a process for producing isododecane that does not use petroleum raw materials.

[0021] Recently, GLOBAL BIOENERGIES disclosed in its application WO2020188033, the production of isobutene by a biological process using a genetically modified organism such as the modified E. Coli bacterium.

[0022] The isobutene gas obtained is then converted into isododecane by a solvent-phase oligomerization reaction followed by a hydrogenation step according to patent application WO2021228824.

[0023] This reaction, known in the chemical industry, has the disadvantage of forming by-products and offering a low yield, which raises questions about the viability of this approach in the long term in terms of volume and cost.

[0024] Nevertheless, more than €100 million was raised by GLOBAL BIOENERGIES for the development of such a process between 2008 and the beginning of 2021, the date of release of the first batch of cosmetic-grade isododecane.

[0025] This long-term economic investment for the production of isododecane from natural raw materials is remarkable.

[0026] Indeed, a second strategy consisting of reducing the quantity of isododecane present in current cosmetic products or even substituting it is a challenge of a completely different magnitude for the cosmetics industry.

[0027] Furthermore, finding a biodegradable substitute for isododecane would be a major advance from an environmental point of view as mentioned in patent application EP3349720, such a compound being able to represent up to a mass percentage of 60% of the cosmetic composition.

[0028] Research has thus been carried out in order to identify compounds likely to offer a satisfactory alternative to isododecane, these compounds having to possess similar volatility characteristics and similar behavior in a formulation, in particular in terms of sensory properties such as the ability to spread on the skin, the sensation to the touch, or even the “non-greasy” character of the film obtained.

[0029] Thus, there remains a need, from an economic and ecological point of view, to have a cosmetic excipient capable of substituting isododecane, in particular as an excipient to be included in cosmetic formulations.

[0030] Surprisingly, it has been demonstrated by the Applicant that such an excipient could be obtained.

[0031] This excipient is a volatile mixture of alkanes as previously defined.

[0032] Preferably, this volatile mixture of alkanes is obtained from fatty alcohols by a Guerbet alcohol reaction followed by a dehydration and hydrogenation reaction. This synthetic route advantageously makes it possible to obtain a substitute excipient for isododecane, from raw materials of natural origin according to an economically viable industrial process in relation to market needs.

[0033] Furthermore, such an excipient is biodegradable according to the OECD 301F method unlike isododecane (CAS 13475-82-6).

[0034] Advantageously, the excipient according to the present invention has a biodegradability of at least 50% according to the OECD 301F method.

[0035] It has also been demonstrated according to the invention that the incorporation of this cosmetic excipient into cosmetic formulations, in particular those for the eyes such as mascara or eyeliner, has the effect of providing said cosmetic formulation with remarkable cosmetic qualities in addition to excellent stability of these formulations, such as ease of application, water resistance, good hold, and a more intense color.

[0036] Furthermore, the incorporation of this cosmetic excipient has made it possible to obtain cosmetic eye makeup formulations which can have a naturalness index greater than 90%.

From 20 to 100% by mass of a fraction A which comprises at least one branched C<10 alkane; b.

[0044] The eye makeup composition according to the invention is characterized in that it is either a mascara composition or an eyeliner composition.

[0045] Preferably, the eye makeup composition according to the invention is a mascara composition.

[0046] Traditionally, according to the book Conception des produits cosmétiques : la formulation, by Anne-Marie PENSE-LHERITIER published in 2014 by LAVOISIER, there are mainly two types of mascara formulations: - Continuous water-based mascaras are also called “water-based mascara” - Continuous oil-phase mascaras are also called “waterproof mascara”

[0047] In the remainder of this invention, we will be mainly interested in this second category of mascara formulation.

[0048] Continuous oil-phase mascaras are mainly based on the use of wax or continuous oil-phase emulsion. The aim is to form a continuous film on the surface of the eyelash, a film that is perfectly water-resistant.

[0049] To do this, the mascara composition comprises in particular a fatty phase and a pigmentary part and this composition may optionally comprise an aqueous phase.

[0053] The pigmentary part includes water-soluble dyes, fat-soluble dyes, pigments, pearlescent agents and glitter.

[0054] Obtaining a mascara is done by finding a subtle balance between these different ingredients.

[0055] Various additives providing specific properties can be added to these ingredients: polymers, absorbent powders, stabilizing additives such as antioxidants, perfume and active ingredients where appropriate.
