Abstract
Description
Title of the invention: Gelled oily association with blurring effect FIELD OF THE INVENTION
[0001] The present invention relates to the cosmetic field, in particular to compositions for the care and / or makeup of keratin materials, and in particular of the skin and / or lips. STATE OF THE ART
[0002] Consumers are constantly looking for high-performance cosmetic products with good sensoriality and composed mainly of ingredients of natural origin. Silicone compounds, which are non-biodegradable, are thus gradually being replaced.
[0003] Silicone elastomers are a category of silicone ingredients widely used in cosmetics, skincare and makeup, because they provide very specific performance upon application and after application, such as particularly high-performance soft focus perfecting optical properties and sensory properties called the "cushion" effect with a very specific glide. We are therefore looking for new ingredients and / or new combinations aimed at replacing them, with equivalent performance.
[0004] We know the use of ingredients (e.g. fillers) with a soft focus / perfecting effect, but they provide a rough and drying effect impacting the sensoriality of the product. And the use of oils, to improve the comfort of applying these products containing fillers, gives a greasy and sticky effect to the application.
[0005] There therefore remains a need to find new ingredients or new combinations that make it possible to reproduce the soft focus effect, the cushion effect and the glide when applying silicone elastomers.
[0006] It is in this context that the Applicant has developed a new gelled oily combination comprising (i) non-volatile oils with a flash point above 130°C, (ii) absorbent fillers having an oil-taking capacity ranging from 120mL / 100g to 400mL / 100g and (iii) organic lipophilic gelling agents. This combination can be used as is or formulated in a final composition, and provides a blurring effect, a cushion effect and glide on application, without a squeaky, greasy or sticky effect.

[0029] By “oil” is meant a fatty substance, insoluble in water, liquid at 25°C and atmospheric pressure.
[0030] Non-volatile oils having a flash point above 130°C
[0031] The flash point of an oil is defined as the lowest temperature at which the vapor above an oil will momentarily ignite or flash if / when an ignition source is passed over or exposed to it.
[0032] The flash point is measured in particular according to ASTM Standard D93-02a
[0033] These non-volatile oils have a dry feel, are not very viscous and have a non-greasy and non-shiny finish.
[0034] The non-volatile oils used according to the invention are advantageously chosen from non-volatile alkanes and non-volatile mixtures of C8-C30 alkanes, preferably non-volatile alkanes and non-volatile mixtures of C10-C25 alkanes, better still C15-C19 alkanes and mixtures of alkanes, hydrogenated polyisobutenes, and mixtures thereof.
[0035] By 'non-volatile C8-C30 alkanes' is meant in particular C15-C30 alkanes.
[0036] Thus, according to a particular embodiment of the invention, the composition of the invention comprises a non-volatile mixture of C8-C30 alkanes, in particular C10-C25, or even C15-C21.
[0037] According to another particular and preferred embodiment, the composition of the invention comprises one or more non-volatile C15-C30 alkanes, in particular C15-C19 alkanes or mixtures of alkanes.
[0038] As non-volatile C15-C19 alkanes, we can notably cite the references following commercial: - VEGELIGHT 1618LC from the company Biosynthis, with INCI name C15-19 ALKANE (and) COCO-CAPRYLATE CAPRATE; - VEGELIGHT 1820 from the company Biosynthis, with INCI name Cl8-21 ALKANE EMOGREEN L19 from the company SEPPIC, with INCI name C15-19 ALKANE.
[0039] As hydrogenated polyisobutenes having a flash point above 130°C, the following commercial references may be mentioned in particular: PARLEAM® LITE (POLYSYNLANE LITE) from NOF Corporation, CAS No. 68937-10-0 and INCI name Hydrogenated Polyisobutene, PARLEAM® (POLYSYNLANE) from NOF Corporation, CAS No. 68937-10-0 and INCI name Hydrogenated Polyisobutene.
[0040] Thus, according to a particular embodiment, the non-volatile oils used according to the invention are chosen from non-volatile alkanes and non-volatile mixtures of C8-C30 alkanes, preferably non-volatile alkanes and non-volatile mixtures of C10-C25 alkanes, more preferably C15-C19 alkanes and mixtures of alkanes, and hydrogenated polyisobutene.
[0041] According to a preferred embodiment, the non-volatile oils used according to the invention are chosen from non-volatile alkanes and non-volatile mixtures of C8-C30 alkanes, preferably non-volatile alkanes and non-volatile mixtures of C10-C25 alkanes, more preferably C15-C19 alkanes and mixtures of alkanes.
[0042] According to a particular embodiment of the invention, the non-volatile oils having a flash point above 130°C will be present in the gelled oily association of the invention in a content ranging from 40 to 80% by weight, preferably 50 to 70% by weight relative to the total weight of the association.
[0043] According to a particular embodiment, the non-volatile oils having a flash point above 130°C will be present in the final composition of the invention in a content ranging from 40 to 80% by weight, preferably 50 to 70% by weight relative to the total weight of the final composition.
[0044] Absorbent fillers with an oil uptake capacity ranging from 120 mL / 100 g to 400 mL / 100 g (otherwise called 'main' fillers according to the invention for the optical blurring effect)
[0045] By "fillers" is meant particles of any shape, colorless or white, mineral or synthetic, insoluble in the medium of the composition. These fillers are used in particular to modify the rheology or texture of the composition and / or to confer a mattifying effect. The fillers can be mineral or organic of any shape: platelet, spherical or oblong.
[0046] Preferably, the fillers are mineral fillers and preferably spherical mineral fillers.
[0047] Preferably, the fillers are spherical particles having a volume median size D50 less than or equal to 25 pm, in particular less than or equal to 20 pm. According to a particular embodiment, the volume median size ranges from 3 to 20 pm, in particular from 5 to 15 pm.
[0048] By “median size in volume” we mean the dimension given by the statistical granulometric distribution to half of the population, called D50 measured with the Malvern-Mastersizer Laser Granulometer.
[0049] The fillers according to the invention are fillers having a capacity to absorb and / or adsorb an oil or a liquid fatty substance, and to confer a blurring effect after application to the skin.
[0050] By blurring or soft-focus effect, it is meant that the fillers used according to the invention are capable of reducing the visibility of skin imperfections, by an immediate optical effect. This blurring effect can be evaluated with the naked eye, after application of the combination according to the invention on the back of the hand by evaluating the level of erasure of the microrelief. The effect can also be evaluated by capturing an image before and after application on the face using a NEXA type device from the Canfield company. Image processing allows a quantitative analysis to be carried out, in particular by visualizing the pores and wrinkles / fine lines.
[0051] Thus, the absorbent fillers according to the invention can be characterized by their oil absorption otherwise called 'oil uptake' or 'oil uptake', expressed in milliliters of oil per gram of filler (ml / g).
[0052] This oil uptake corresponds to the quantity of oil absorbed and / or adsorbed by the load and can be characterized by measuring the oil uptake according to standard methods. In particular, the method for determining the powder oil uptake described in standard NF T 30-022 can be cited, and corresponding to the quantity of oil adsorbed on the available surface of the load, expressed as the volume of oil adsorbed over the mass of the load.
[0053] According to a particular and preferred mode, the following method will be used for taking oil:
[0054] - we pour the artificial sebum (25% Jojoba oil, 15% squalane and 60% miglyol 829 (CAPRYLIC / CAPRIC / SUCCINIC TRIGLYCERIDE) on 1 g of powder (test load);
[0055] - with the spatula, gently mix in the powder, slightly crushing it, the objective being to arrive at a mastic paste which does not crumble and comes off easily;
[0056] - the result is recorded in ml of artificial sebum per 1 g of powder. It is necessary to convert in ml / 100 g by multiplying the reading value by 100;
[0057] - the measurement is to be carried out twice on each sample, if the difference between these 2 measurements are greater than 0.05 ml, a 3rd measurement is taken.
[0058] The absorbent fillers used according to the invention have an oil uptake capacity greater than or equal to 120 mL / 100 g and less than or equal to 400 mL / 100 g.
[0059] According to a particular embodiment of the invention, fillers are used having an oil uptake capacity of between 150 mL / 100 g and 350 mL / 100 g, preferably between 200 mL / 100 g and 300 mL / 100 g.
[0060] Preferably, these will be mineral fillers having an oil uptake capacity greater than or equal to 120 mL / 100 g and less than or equal to 400 mL / 100 g.
[0061] Non-limiting examples of fillers that can be used according to the invention are described in the following table 1:

[0077] These additional fillers will be used in a total content lower than the aforementioned main fillers, in particular in a content 2 to 6 times lower than the total content of the main fillers. Thus, according to the invention, the ratio of the total content of main fillers to the total content of additional fillers will range in particular from 6:1 to 2:1, in particular 5:1 to 3:1, preferably 4:1.
[0078] By way of example and according to a preferred embodiment, for a total filler content (main and additional) of 25% by weight in the gelled oily association (or in the final composition), 20% of main fillers and 5% of additional fillers by weight will be used in the gelled oily association (or in the final composition).

[0082] In the final composition, the total filler content will also range in particular from 15 to 35% by weight, preferably 20 to 30% by weight relative to the total weight of the final composition.
[0083] Thus, according to a particular embodiment, the gelled oily association according to the invention comprises at least: i. 40 to 80% by weight, preferably 50 to 70% by weight of non-volatile oils of alkane or hydrogenated polyisobutene type characterized by a flash point greater than or equal to 130°C, as defined above, relative to the total weight of the gelled oily association, ii. 15 to 35% by weight, preferably 20 to 30% by weight of filler(s) having an oil uptake greater than or equal to 120mL / 100g and less than or equal to 400mL / 100g, as defined above, relative to the total weight of the gelled oily association, and iii. 5 to 30% by weight, preferably 10 to 25% by weight of organic lipophilic gelling agent(s), relative to the total weight of the composition.
[0084] Preferably, we will use: i. 50 to 70% by weight of non-volatile alkanes or non-volatile mixtures of C8-C30 alkanes, more preferably non-volatile alkanes or non-volatile mixtures of C10-C25 alkanes, preferably 15-C19 alkanes or mixtures of alkanes, relative to the total weight of the gelled oily combination, and ii. 20 to 30% by weight of mineral fillers, preferably silica powders, having an oil uptake greater than or equal to 120mL / 100g and less than or equal to 400mL / 100g, relative to the total weight of the gelled oily association and iii. 5 to 30% by weight, preferably 10 to 25% by weight of organic lipophilic gelling agent(s), relative to the total weight of the composition.
[0085] These filler and oil contents respectively thus allow total absorption of said oils by said fillers; we speak of saturation of the fillers by the oils. The mixture of fillers and oils according to the invention forms a homogeneous fluid to viscous mixture, with an optical blurring effect.
[0086] In addition to non-volatile oils with a flash point above 130°C and fillers with an oil uptake capacity ranging from 120mL / 100g to 400mL / 100g, the gelled oily combination will also comprise at least one organic lipophilic gelling agent.

[0208] Example 1: Selection of a mixture of fillers and non-volatile oils
[0209] Different oil / filler blends, in a 75 / 25 ratio, are prepared and evaluated for their texture properties, optical blurring effect and sensoriality upon application.
[0210] As oils, volatile alkanes (C9-C12 alkanes, product VEGELIGHT SILK) and non-volatile alkanes with a flash point greater than or equal to 130°C were used respectively. (C15-C19, product VEGELIGHT 1618). In another experiment, hydrogenated polyisobutenes (product POLYSYNLANE) were also tested, as other non-volatile oils with a flash point greater than or equal to 130°C.
[0211] The mixtures were prepared according to the following protocol: the filler is added in fine rain into the tested oil, with stirring. Slow stirring is carried out and then the stirring is gradually increased until a homogeneous mixture is obtained.
[0212] The criteria evaluated by a panel of formulation experts are as follows: texture of the gel, optical effect, color of the film on the skin and sensoriality after application to the skin.
[0213] Ratings are given for each of the criteria.
[0214] “OK”: homogeneous gel texture / blurring effect / no white film on the skin / soft and powdery touch
[0215] “KO”: release or sedimentation of the charge / no blurring effect / white film on skin / dry and rough feel
[0216] In the following table, 'OK' means that the oil / charge mixture satisfies the 4 evaluated criteria and 'KO' means that at least one of the criteria is not satisfied (noted in the table below).
[0217] The results are presented in the following table:

[0220] These results show that non-volatile oils with a flash point above 130°C, such as C15-C19 alkanes and hydrogenated polyisobutenes, make it possible to obtain, in association with fillers having an oil uptake ranging from 120mL / 100g to 400ml / 100g, a homogeneous gelled texture / blurring effect / no white film on the skin / soft and powdery feel, compared to volatile oils (volatile alkanes) associated with the same fillers.
[0221] Example 2: Optimization of load association
[0222] Several commercial references of silica according to the invention were tested in association with other fillers in a 20 / 5 ratio (20 silica / 5 other filler), in a mixture with the non-volatile oil C15-C19) in the same ratio as that used in example 1 (oil / filler ratio of 75 / 25).

[0224] These results show that it may be advantageous to use at least 2 fillers of different nature to improve the optical and sensory properties of the composition. Example 3: Gelling agents
[0225] Different gelling agents were tested, respectively at a content of 25% by weight in the mixture or a content of 5% by weight in the mixture according to their gelling power.
[0226] These mixtures were prepared according to the following protocol: the fillers and the oil were mixed until the fillers were saturated (complete absorption of the oil) then the mixture was heated to a temperature between 85°C and 110°C and the oily gelling agent was added until a homogeneous gel was obtained.
[0227] The gel can be formulated subsequently, for example an anhydrous composition, or used as is directly, after shaping by casting by adjusting the gelling rate.
