Description

Title of the invention: Keratinous material cleaning and / or care composition. Technical field

[0001] The present invention relates to a composition for cleaning and / or conditioning keratinous material, preferably hair and scalp. The present invention also relates to a process for cleaning and / or conditioning keratinous material, preferably hair and scalp. STATE OF THE ART

[0002] The scalp is an epidermis that undergoes continuous renewal, like the rest of the skin tissue, and is rich in sebaceous glands. Under normal circumstances, the scalp is renewed by an imperceptible and invisible shedding of superficial skin cells. However, excessive renewal of the cells in the stratum corneum of the scalp, for various reasons, can lead to the formation of large, thick patches of cells visible to the naked eye, known as "dandruff".

[0003] Dandruff is a chronic, frequent, and recurring condition that is socially debilitating due to its clearly unsightly appearance. This dandruff of the scalp results from an alteration of the epidermis' barrier function. Furthermore, these conditions can cause itching or pruritus, leading to scratching behavior that exacerbates the appearance of dandruff.

[0004] Many cosmetic cleansing and / or skincare products for keratinous materials have been developed to include at least one anti-dandruff agent in order to address the aforementioned problems. However, it is often difficult for cosmetic products containing an anti-dandruff agent to rapidly or sufficiently inhibit microorganisms. Furthermore, good foaming properties are desirable to consumers. However, it is often difficult for cosmetic products containing an anti-dandruff agent to provide a desirable foaming property.

[0005] Therefore, there is a need for a keratinous material cleansing and / or care composition, which includes at least one anti-dandruff agent and which can ensure faster and more satisfactory inhibition of microorganisms and thus better anti-dandruff efficacy, and which is also capable of providing a desirable foaming property. Summary of the invention

[0006] The inventors have discovered that such a need can be satisfied by the composition according to the present invention.

[0007] According to a first aspect, the present invention relates to a composition, preferably for cleaning and / or caring for keratinous material, comprising: a. 0.6% by weight to 30% by weight of at least one alpha-hydroxy acid, relative to the total weight of the composition; b. at least one beta-hydroxy acid and / or derivatives thereof; and c. at least one selenium sulfide.

[0008] According to a second aspect, the present invention relates to a process for cleaning and / or caring for keratinous material, preferably hair and scalp, comprising the following steps: a. the application of the composition as described above to a wet keratinous material; b. massaging the keratinous material for 2 seconds to 120 seconds; and c. rinsing the keratinous material with water.

[0009] The inventors discovered that after application of the composition to keratinous material, preferably hair and scalp, the composition can provide improved anti-dandruff efficacy and in addition a desirable foaming property.

[0032] By the term "beta-hydroxyl acid", according to the present invention, we mean a carboxylic acid having a hydroxyl functional group and a carboxylic functional group separated by two carbon atoms.

[0033] Preferably, the "derivative" in the expression "beta-hydroxylated acid and / or derivatives thereof" means that the hydroxyl functional group of the beta-hydroxylated acid, rather than the carboxylic functional group, is modified and preferably acylated.

[0044] Selenium sulfide is a basic commercial product. Selenium sulfide is generally considered to be a compound containing one mole of selenium and two moles of sulfur. However, it can take the form of a cyclic structure, SexSy, in which x + y = 8. Since sulfur and selenium readily form rings and chains, selenium sulfide is not a pure chemical compound, but a mixture, for example, a mixture of eight-membered cyclic compounds where the overall Se:S ratio is 1:2 (often abbreviated as SeS2).

[0045] Selenium sulfide is used to treat dandruff and certain scalp infections (seborrheic dermatitis). It reduces itching, irritation, and redness of the scalp.

[0157] The composition was prepared from a process comprising the following steps: 1. Mix each component of Phase A until homogeneous to form Premix 1; 2. Add each component of Phase B into Premix 1 and mix thoroughly until transparent to form Premix 2; 3. Add each component of Phase C into Premix 2 to form Premix 3; 4. Add the selenium sulfide from Phase D to Premix 3 and mix until homogeneous to form Mixture 1; and 5. Correct the pH value of Mixture 1 to 3.8 by adding sodium hydroxide to form the final composition. Composition evaluation

[0158] The compositions as prepared were evaluated in terms of anti-dandruff efficacy and foaming property. Anti-dandruff efficacy trial

[0159] The anti-dandruff efficacy of each composition of Examples 1 to 6 of the invention and of comparative Examples 1 and 2 was evaluated as follows: 15 ml of each test sample were diluted by a factor of 10 and kept at a temperature of 20 °C for 5 min. The diluted sample was rapidly and immediately mixed with a test solution of Malassezia furfur. After contact for 2 min or 5 min, the surviving microorganisms were tested by a plate counting method.

[0160] The results of the anti-dandruff efficacy of the compositions of examples 1 to 6 of the invention and comparative examples 1 and 2 are presented respectively in the following Table 3.

[0161] [Tables3] Ex. 1 Ex. 2 Ex. 3 Ex. 4 Ex. 5 Ex. 6 EC. 1 EC. 2% inhibition of Malassez ia Furfur (2 min) 99 99 31 99 99 99 20 15% inhibition of Malassez ia Furfur (5 min) 99.9 9 99.9 9 78 99.9 9 99.9 9 99.9 9 35 28

[0162] From the data in Table 3 above, it can be seen that all the compositions of Examples 1 to 6 of the invention, comprising an amount greater than or equal to 0.6% by weight of an alpha-hydroxy acid, relative to the total weight of each composition, of a beta-hydroxy acid and / or derivatives thereof and of a selenium sulfide, can provide a % inhibition greater than or equal to 30% after contact of the microorganism Malassezia Furfur with each composition for 2 min, and a % inhibition greater than or equal to 70 after contact of the microorganism Malassezia Furfur with each composition for 5 min.

[0163] In contrast, each of the compositions in comparative examples 1 and 2, which do not include a beta-hydroxy acid and / or derivatives thereof, or include a quantity less than 0.6% by weight of an alpha-hydroxy acid provides a much lower % of inhibition after contact of the Malassezia Furfur microorganism with each composition for 2 min and / or 5 min. Foaming property test

[0164] For the Foam Volume test protocol: a. prepare water at 10 fH (French hardness) (111 mg of CaCl2 dissolved in 1 L of DI water); b. Weigh out 4 g of each composition from examples 1 to 6 of the invention and place them in a kitchen blender; c. Weigh out 76 g of 10 fH water prepared to dilute each composition by a factor of 20; d. Turn on the kitchen mixer (PHILIPS HR2056) and mix for 1 minute; e. Quickly transfer the foam produced and the liquid into a 500 ml graduated cylinder; and f. Read the entire volume.

[0165] The higher the volume of foam, the greater the quantity of foam, and vice versa.

[0166] The results of the foaming property of the compositions of Examples 1 to 6 of the invention are presented respectively in the following Table 4.

[0167] [Tables4] Ex. 1 Ex. 2 Ex. 3 Ex. 4 Ex. 5 Ex. 6 Foam volume (ml) 200 215 225 215 215 215

[0168] As is known in the field of cleaning products, a foam volume greater than or equal to 200 ml is considered qualified. From the data in Table 4 above, it can be seen that all the compositions of Examples 1 to 6 of the invention, comprising an amount greater than or equal to 0.6% by weight of an alpha-hydroxy acid, relative to the total weight of each composition, of a beta-hydroxy acid and / or derivatives thereof, of a selenium sulfide, can provide a foam volume greater than or equal to 200 ml.

[0169] In summary, the compositions according to the present invention can ensure faster and more satisfactory inhibition of microorganisms and therefore better anti-dandruff efficacy, and in addition provide a desirable foaming property.
