Description

[0001] This application is a divisional application of patent application No. 201880081919.4, filed on December 18, 2018, entitled "A foaming aqueous composition comprising ricinoleic acid, alkyl polysaccharide and polysaccharide".

[0002] This invention relates to an aqueous foaming composition comprising trichomoniatic acid, at least one base, at least one nonionic surfactant selected from alkyl polysaccharides, and at least one polysaccharide, and also to the use of said composition, particularly in the cosmetic field, as a product for cleaning keratin materials such as skin, keratin fibers (eyelashes and hair) or scalp and / or removing cosmetics therefrom, and also for treating oily skin and / or disinfecting skin and / or scalp.

[0003] Skin cleansing is crucial for facial care. It must be as effective as possible because sebum residue, such as excess sebum, and residue from daily beauty and cosmetic products can accumulate in skin folds and potentially clog pores, leading to blemishes.

[0004] One way to satisfactorily cleanse the skin is by using foaming cleansing products. Commercially available foaming cleansing products are in the form of foaming strips, gels, or creams. These products typically contain soap, which has the advantage of producing creamy foam, but can cause tightness due to the excessive cleansing power of soap; or foaming surfactants, such as sulfate surfactants, particularly sodium lauryl sulfate (SLS) or sodium laureth sulfate (SLES), or amphoteric surfactants, such as cocoyl betaine, cocamidopropyl betaine, or sodium coamphodiacetate, which are highly effective in terms of foaming and cleansing power, but are wrongly or rightly questioned due to their ecotoxicity or ecologically unfriendly environmental characteristics.

[0005] As the formulation of environmentally friendly cosmetic products is becoming a major challenge to meet new consumer expectations, especially for eco-designed and / or natural products, it is necessary to develop foaming compositions that are free of sulfate surfactants and amphoteric surfactants, which have good cosmetic qualities, mainly in terms of viscosity and foaming, as well as good cleansing and / or cosmetic removal capabilities.

[0006] The use of spirochete penicillin, an environmentally non-toxic microbial-derived biosurfactant, has been proposed in cosmetic compositions. However, when used alone, its cosmetic removal ability and foaming properties are not entirely satisfactory.

[0007] The use of spirulinamic acid and / or its salts in combination with other foaming surfactants has also been proposed, particularly in patent applications WO 2015 / 067779 and WO 2015 / 067785.

[0008] However, the cosmetic removal ability and foaming properties of the trichomoniatic acid-based compositions described in the prior art are still insufficient.

[0009] In addition, foamed products can be thickened by salts such as sodium chloride, certain surfactants, or by adding alkyl-PEG thickeners such as PEG-150 distearate or PEG-55 propylene glycol oleate, or by adding natural gum gelling agents, especially xanthan gum, dextran gum or carrageenan gum.

[0010] Thickening with salt is a known method, widely used in surfactant systems containing sulfates and amphoteric substances because it is inexpensive and does not compromise foam quality; however, it typically does not significantly thicken systems that do not contain sulfates and / or amphoteric substances. On the other hand, increasing the viscosity of the medium with another thickener or gelling agent is a more common method, but it often has a negative impact on the foam quality of the formulation (foam initiation, foam volume, foam stability, and durability, etc.).

[0011] Therefore, it would be good to have a foaming composition that does not contain sulfate or amphoteric surfactants, which has good viscosity, good cosmetic removal ability and good foam quality.

[0012] It has been unexpectedly discovered that a combination of ricinoleic acid, at least one base, at least one nonionic surfactant selected from alkyl polysaccharides, and at least one polysaccharide enables the preparation of cleaning and / or cosmetic removal compositions with good cosmetic removal capabilities and excellent foam quality.

[0013] Therefore, one subject of the present invention is a composition, particularly a cosmetic composition, and more specifically a foaming aqueous composition for cleaning keratin materials and / or removing cosmetics from keratin materials, comprising cucurbitacinic acid, at least one base, at least one nonionic surfactant selected from alkyl polysaccharides, and at least one polysaccharide, wherein the ratio R1 of the molar number of the base to the molar number of the cucurbitacinic acid is strictly greater than 1.

[0014] The composition according to the invention enables the production of transparent foaming gels with good viscosity levels and good cosmetic quality, primarily good cosmetic removal ability and good foaming properties (initiation, quality, quantity, stability and persistence, etc.), especially when combined with a self-foaming device.

[0015] The resulting foam has good foam initiation, forms in large quantities, and is stable over time, which gives the composition a very satisfactory application time (or duration of action).

[0016] In the context of this invention, the term "action time" or "application time" refers to the time during which the foam remains sufficiently abundant and continuously applied to the keratin material without flowing. Action time is considered satisfactory when the application time is 30 to 75 seconds, preferably 50 to 70 seconds, and even more preferably 55 to 70 seconds.

[0017] Furthermore, the composition according to the invention is stable over time.

[0018] The compositions according to the invention are intended for topical application and therefore contain a physiologically acceptable medium. The term "physiologically acceptable medium" here means a medium compatible with keratin materials.

[0019] In the context of this invention, the term "keratin material" specifically refers to skin, scalp, keratin fibers (such as eyelashes, eyebrows, hair, body hair, nails) and mucous membranes such as lips, and more particularly to skin (body, face, periorbital area, eyelids).

[0133] The following examples are for illustrative purposes only and are not intended to be limiting. Unless otherwise stated, the quantities shown are weight percentages of the starting material (SM).

[0134] Example The examples below were performed on SkinFX-type neutral carriers, which are in vitro carriers that mimic the contours and biomechanical properties of skin. These carriers are typically made of silicone gel with a very thin polyurethane layer superimposed on top. Various colors are available, similar to the diverse skin tones found in the world.

[0135] A scheme for assessing the ability of cosmetics to be removed. The cosmetic removal ability of various test compositions was evaluated in the following manner.

[0136] The test was conducted on a thick layer of white SkinFX (index number SKINFX-SH-H40-BAK-WHI). The foundation used was L'Oréal Paris's "Infaillable 24h Tenue et Confort Teinte 220" foundation.

[0137] Clean and dry the SkinFX surface. Then measure the exposed surface using colorimetry (measure L, a, and b in three areas).

[0138] Then, 14 µl of foundation was applied to the surface from which the cosmetics were to be removed. The foundation was applied using a finger by pressing the finger against the surface for 15 seconds, 15 times each time. The SkinFX was then dried on a hot plate at 32°C for 15 minutes. The cosmetic surface was then measured colorimetrically (measurements were made in three areas: L, a, and b).

[0139] Generate 0.4 g of foam using a self-foaming device and apply it to the surface from which cosmetics will be removed. Clip the foam with your fingers for 20 seconds. Then pass a cotton pad soaked in 2 ml of water over the surface, followed by a second cotton pad also soaked in 2 ml of water. Perform colorimetric measurements on a SkinFX device to determine the amount of foundation remaining (measurements in three areas: L, a, and b).

[0140] The value that allows us to evaluate the cosmetic removal ability of the composition is the cosmetic removal percentage (ΔE / ΔEmax) * 100, calculated as follows.

[0141] Calculation of percentage of cosmetic removal 1) Color difference between made-up skin and bare skin = ΔEmax: ΔE max = (Δa1 2 + Δb1 2 + ΔL1 2 ),in Δa1 = a_naked skin - a_made-up skin Δb1 = b_naked skin - b_made-up skin ΔL1 = L_naked skin - L_made-up skin 2) Color difference between skin with cosmetic removal and skin with makeup = ΔE: ΔE = (Δa2 2 + Δb2 2 + ΔL2 2 ),in Δa2 = a cosmetic skin removal - a makeup skin Δb2 = b cosmetics removing skin - b makeup skin ΔL2 = L_cosmetics_removing_skin - L_cosmetic_skin For a given cosmetic removal product, the average percentage of cosmetic removal corresponds to the average of three (ΔE / ΔEmax)*100 values.

[0142] Scheme for assessing foam properties The texture of the foam was measured according to the following method: Foam is prepared using a self-foaming device containing the formulation to be evaluated by applying four consecutive presses to generate a sufficient amount of foam for measurement. The container is then leveled using a scraper to make its surface as uniform as possible.

[0143] The texture of the foam obtained with the test composition was characterized using a TA. XT. plus texture meter from Stable Micro Systems, equipped with a head capable of detecting a maximum force of 50 N. The geometry used was a polycarbonate A / BE chamber consisting of a cylindrical container (height = 70 mm, diameter = 50 mm) and a disc (height = 5 mm, diameter = 45 mm), connected to the measuring head via a metal handle. Measurements were performed by reverse extrusion, recording the force as a function of time, corresponding to outward circulation (module penetration into the sample) and return circulation (module extraction from the sample). The following parameters were extracted from these curves: maximum outward force or firmness, area under the outward curve or consistency, maximum extraction force or cohesive force, and area under the extraction curve or viscosity index. The recorded parameters for these curves were: a pre-test velocity of 2 mm / s, a test velocity of 1 mm / s, a post-test velocity equal to the test velocity, and a penetration depth into the sample of 8 mm.

[0144] The options for this measurement method are as follows: Test mode: Compression measurement; Test speed: 1.0 mm / s; Temperature 20°C ± 1°C.

[0145] The results given correspond to the average area under the outward curve of two measurements performed on each composition.

[0146] Comparison Examples Produce the following composition.

[0147] Preparation method of the composition: Compositions 1 through 7 were all prepared at room temperature according to the same procedure. Spirodinic acid was weighed and added to water using a Rayneri mixer (300 rpm) with mechanical stirring. A dispersion was obtained. The amount of arginine required to form the spirodinic acid monosalt (preferably 1.1 equivalents) was added, and the mixture was stirred for 10 minutes until both compounds were completely dissolved. Finally, the alkyl polysaccharide glycoside was added with stirring until completely dissolved. At the end of the manufacturing process, the polysaccharide was added with continued stirring. Low-speed stirring was required to prevent foaming of the mixture during manufacturing.

[0148] Compositions 1, 2, 6, and 7 were evaluated for their cosmetic removal properties. The results are as follows: These results indicate that cucurbitacin alone has only a moderate effect on cosmetic removal. When combined with alkyl polysaccharide glycosides, cosmetic removal results are improved at the same concentration of emulsifier. The cosmetic removal ability is significantly improved when the composition also contains polysaccharides.

[0149] Compositions 1 to 7 were evaluated for their foam quality. The results are as follows: These results indicate that the foam quality is significantly better when the composition contains a combination of trichomoniatic acid, alkyl polysaccharides, and polysaccharides.
