Description

Title of the invention: KERATINOUS MATERIAL CARE KIT technical field

[0001] The present invention relates to a kit, preferably for the treatment of keratinous materials. The present invention also relates to a non-therapeutic method for the treatment of keratinous materials. STATE OF THE ART

[0002] Among all the compositions for the care of keratinous materials, in particular of the skin, masks are known to have a high penetration efficiency on keratinous materials.

[0003] On the market, emulsion-type masks are less popular than gel-type masks. This may be due to the sticky finish on the skin after application.

[0004] Therefore, it will be desirable to reduce the sticky texture of the emulsion of emulsion-type masks.

[0005] It has also been observed that some oily compositions for emulsion-type masks on the market are not very stable, which is not unpleasant.

[0006] Thus, it is also desired to improve the stability of oily compositions for emulsion-type masks.

[0007] Furthermore, the formulation of environmentally friendly cosmetic products, which are designed and developed taking environmental issues into account, is becoming a major objective in an effort to meet global challenges.

[0008] It is therefore essential to offer more sustainable compositions and ingredients to address these environmental concerns.

[0009] 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 materials with a high naturalness index and / or materials of natural origin, and more specifically, materials of plant origin, while reducing the use of petrochemical compounds. Summary of the invention

[0010] An object of the present invention is to propose an emulsion-type mask, which comprises a stable oily composition and / or will provide a less sticky feeling to keratinous materials.

[0011] Another object of the present invention is to propose a non-therapeutic method for the treatment of keratinous materials.

[0012] Thus, according to a first aspect, the present invention proposes a kit, preferably for the care of keratinous materials, comprising: A. a first container comprising at least one substrate and at least one aqueous composition; and B. a second container comprising at least one oily composition, including: i. at least one vegetable oil, ii. at least one polyglyceryl surfactant, and iii. at least one nonionic surfactant other than polyglyceryl surfactants.

[0013] The inventors have discovered that the composition of the present invention is stable.

[0014] The inventors have also discovered that the oily and aqueous compositions in the kit according to the present invention can form an emulsion providing a less sticky feel.

[0015] The kit according to the present invention is suitable for use as a mask, in particular for the care of keratinous materials.

[0016] According to a second aspect, the present invention proposes an oily composition, comprising: I. more than 20% by weight of at least one vegetable oil, relative to the total weight of the composition, It contains at least one polyglyceryl surfactant, and III. at least one non-ionic surfactant other than polyglyceryl surfactants.

[0017] According to a third aspect, the present invention proposes a non-therapeutic method for treating keratinous materials with the kit according to the present invention, comprising: a. the mixing of the oily composition and the aqueous composition to form an emulsion on the substrate; and b. the application of the substrate with the emulsion onto keratinous materials.

[0018] Other subjects and features, aspects and advantages of the present invention will be presented in the following description and will be partly evident from the description, or may be learned through practice of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0121] 1) mixture of water, glycerin, pentylene glycol and propanediol at 80 °C in stirring to obtain an aqueous mixture; and

[0122] 2) introduction of xanthan gum and potassium hydroxide into the mixture aqueous mixture with agitation to obtain the aqueous composition. Inventive examples 3 and 4

[0123] The kits for Inventive Examples (IE) 3 and 4 were prepared by pouring the oily composition of Inventive Example 1 and the aqueous composition of Example 2 in a weight ratio of the oily composition to the aqueous composition (O / W ratio) as indicated in Table 5 into different chambers of a double-layered bag chamber, one chamber containing the oily composition and one chamber containing the fabric made of viscose fibers and the aqueous composition.

[0124] [Tables5] EI.3 EL4 Ratio H / E 1:5 1:10 Assessment of stickiness texture

[0125] The sticky texture provided by each mask in the kits of inventive examples 3 and 4 was evaluated by 10 volunteers in a blind test. The test kit was opened, and the oily and aqueous compositions it contained were mixed. The fabric was then massaged until the composition became milky and uniform to form a mask. The resulting mask was applied to each volunteer's skin for 15 minutes, then removed. The volunteers were asked to rate the sticky texture provided by each mask on a scale of 0 to 10 according to the following standard, and the average of the scores was calculated for each mask.

[0126] 0: means non-sticky,

[0127] 2: means very slightly sticky,

[0128] 4: means slightly sticky,

[0129] 6: means sticky,

[0130] 8: means very sticky,

[0131] 10: means extremely sticky.

[0132] The results of the sticky texture delivered by each mask have been summarized in Table 6.
