Description

Skin cleansing composition {Skin cleansing composition}

The present invention relates to a skin cleanser composition and a method for preparing the skin cleanser composition.

Recently, cosmetics with anti-aging functions aimed at preventing aging are expanding beyond cell regeneration to restoration with more advanced technology. However, in Korea, it is saturated with functional cosmetics for delaying aging and wrinkle improvement, but it is difficult to find a product exclusively for 'old man'.

Beauty and personal health care products for the elderly and those who suffer from the peculiar smell of the elderly caused by aging are constantly in demand, and due to such high demand, the elderly body odor (eg, aging in the sense that it occurs together with aging) Products, which are also suppressed) are being released from many companies one after another.

It is known that the proportion of cis-6-hexadecenoic acid, a fatty acid contained in sebum, decreases relatively with age, and the proportion of cis-9-hexadecenoic acid (palmitoleic acid) increases. In addition, a characteristic old man odor is generated due to a substance generated by oxidative decomposition of palmitoleic acid, which is a substance called nonnal. Due to aging, metabolism is not smooth and more waste products remain on the skin, and more nonnal, a substance produced by the decomposition of unsaturated fatty acids in these sebaceous glands, is created, and a characteristic odor is emitted. Therefore, in order to remove the body odor peculiar to the elderly, it is essential to remove sebum containing palmitoleic acid discharged through the sebaceous glands and nonnal, which is the cause of body odor.

On the other hand, conventionally, skin cleansing agents such as shampoo, soap, cleansing, and face washes are expected to have an effect of removing not only dust and dirt adhering to the skin or hair, but also sebum of the skin such as the scalp, face, and body. Therefore, various surfactants are used in skin cleansing agents in terms of solubility with sebum and feeling of use to remove sebum.

Japanese Patent Publication No. 2005-075797 has a saponification value of 95 mgKOH / g or more, a monoester content of 80% or more, and a composition for removing skin contamination containing a polyglycerin fatty acid ester having water solubility and a composition thereof. Disclosed is a composition for removing skin contamination having high removal property against makeup and sebum contamination by impregnating the support. However, the composition for removing skin contamination is effective for removing makeup and sebum on the face, but has limited effect on removing sebum components secreted from the skin of the elderly.

Japanese Unexamined Patent Publication No. 2014-034560 is made of N-acyl sarcosine salt, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene cured castor oil and at least two kinds selected from monoisostearic acid polyoxyethylene glyceryl and water. As a composition for skin cleansers, a composition for skin cleansers has been disclosed that exerts an excellent cleansing and removal effect on the specific sebum component secreted from a middle aged person, but it has not been sufficiently satisfactory even for the removal effect on nonnal, which is a causative agent for the elderly body odor. .

Japanese Patent Publication No. 2014-034560

Accordingly, the problem to be solved by the present invention is to provide a skin cleanser composition effective for removing aging odor, that is, aging body odor, which occurs in the elderly by exerting excellent cleaning effects on the specific sebum components secreted from the skin of the elderly and substances causing body odor in the elderly. Is to provide.

In order to solve the above problems, the present invention comprises (a) 1 to 30% by weight of the total weight of the composition, (b) 0.1 to 15% by weight of amphoteric surfactant and (c) 0.1 to 18% by weight of polyhydric alcohol. Provided is a skin cleanser composition.

In the present invention, the mass ratio of the soap and amphoteric surfactant may be 1: 1 to 9: 1, 1: 1 to 3: 1, 3: 1 to 5: 1, 1: 1 to 5: 1, 1: 1 to 7: 1, 3: 1 to 9: 1, or 7: 1 to 9: 1. The mass ratio may be preferably 2: 1 to 8: 1. If the ratio is out of the above range, the present invention may not be effective in removing the body odor of the elderly.

As a result of research efforts to overcome the problems of the prior arts, the present inventors include polyhydric alcohol alone or in a skin cleanser composition containing soap in the cleanser composition, and an amphiphilic surfactant as a main cleaning component in a specific ratio with soap. When included as a mixture of two or more, the present invention was found by discovering the surprising fact that the cleaning effect is excellent, and in particular, it exhibits an excellent removal effect on the specific sebum component secreted from the skin of the elderly and substances causing the body odor of the elderly.
