Description

[0001] Skin cleansing composition [0002]

The present invention relates to a skin cleanser composition and a method of making a skin cleanser composition.

In recent years, anti-aging cosmetics for anti-aging purposes have been expanding their scope beyond cell regeneration to more advanced technologies. However, in Korea, functional cosmetics for delaying aging and wrinkles are saturated, but it is hard to find products for the elderly only.

The beauty and personal health care products for the elderly and the people suffering from the aging-specific odor of the elderly are constantly being demanded. Due to this high demand, the elderly body odor (for example, ) Is a product that is being released continuously by many companies.

It is known that the proportion of cis-6-hexadecenoic acid, which is a fatty acid contained in sebum, is relatively decreased and the proportion of cis-9-hexadecenoic acid (palmitoleic acid) is increased with aging. In addition, due to the oxidation and decomposition of palmitoleic acid, a specific odor of the elderly people is generated, which is called Nonenal. Due to the aging process, the metabolism is not smooth and much waste material is left on the skin, and the nonenal, which is generated by the decomposition of the unsaturated fatty acid in these sebaceous glands, is made more and the unique smell is emitted. Therefore, it is essential to remove sebum containing palmitoleic acid and nonenal which are the cause of the body odor of the elderly, which are discharged through the sebaceous glands, in order to remove the odor of the elderly person.

On the other hand, conventionally, a skin cleanser such as shampoo, soap, cleansing, and a cleanser is expected not only to remove dust and dirt adhered to skin or hair, but also to remove sebum of skin such as scalp, face, body. Therefore, in order to remove sebum from the skin cleanser, a variety of surfactants have been used in view of the solubility with sebum and feeling of use.

Japanese Patent Application Laid-Open No. 2005-075797 discloses a skin decontamination composition comprising a polyglycerin fatty acid ester having a saponification value of 95 mgKOH / g or more, a monoester content of 80% or more, and a solubility in water, There is disclosed a composition for removing skin decontamination which has a high removal property against makeup and sebum contamination by impregnating a support. However, the composition for removing skin contaminants is effective for removing makeup and sebum from the face, but the effect is limited for removing a specific sebum component secreted from the elderly skin.

Japanese Laid-Open Patent Application No. 2014-034560 discloses a cosmetic composition comprising at least two selected from N-acyl sarcosinate, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene hydrogenated castor oil, and polyoxyethylene glyceryl monoisostearate and water A composition for a skin cleanser that exhibits an excellent cleaning and removing effect on a specific sebum component secreted from a man of middle age by using a composition for a skin cleanser has been disclosed, but the removal effect on nonenal, which is a substance causing the body odor of the elderly, .

Japanese Laid-Open Patent Application No. 2014-034560

Therefore, a problem to be solved by the present invention is to provide a skin cleansing composition which is effective for removing odor, which is generated in the elderly, that is, the elderly body, by exerting an excellent cleansing effect on a specific sebum component secreted from the elderly skin and a cause- .

The present invention provides a composition comprising (a) from 1 to 30% by weight of a soap, (b) from 0.1 to 15% by weight of an amphoteric surfactant, and (c) from 0.1 to 18% by weight of a polyhydric alcohol, A skin cleanser composition is provided.
