Description

Skin cleanser composition

The present invention relates to a cleaning composition for protecting the skin, and in particular, it is a skin cleanser composition which can remove powders and oily soil of makeup make-up while relatively less degreasing of the skin.

In recent years, as the industry develops and the living environment improves, the hygiene concept, especially the hygiene concept for the skin, has increased, so there has been an increasing interest in skin protection cleaners used to clean the skin, and the amount of usage is also increasing day by day. As such skin protection cleaners, soaps mainly prepared using fatty acid alkali metal salts, cleaners containing ionic and nonionic surfactants, and cleansing creams containing a large amount of oily components are already widely used.

However, the soap as described above is used to the skin to cause strong skin degreasing phenomenon damage to the skin, so in order to remove these disadvantages, cream-type soap containing a skin protection agent, etc. has recently been developed. However, soaps prepared using the fatty acid alkali metal salts described above, or detergents such as foam cleansing containing a surfactant, contain an aqueous component that can remove dust, etc. Since powders and oily soils are not easily removed, there is a problem in that an expensive cream-type cleansing cream containing oily ingredients is used twice.

Therefore, the present invention is to solve the disadvantages of the conventional skin cleansers as described above, while fully exhibiting the action of the water-based ingredients to remove dust, such as the degreasing phenomenon of the skin is relatively small and at the same time powder and oil of makeup cosmetics It is an object of the present invention to provide a cleansing composition for protecting skin to remove dirt.

Hereinafter, the present invention will be described in detail.

The present invention adds 5.0-7.0 parts by weight of polyhydric alcohol, 7.0-10.0 parts by weight of anionic surfactant and 5.0-6.0 parts by weight of alkali metal salt to 30.0-50.0 parts by weight of water and heat it to a temperature of 50-60 ° C. A) was preliminarily prepared, 10.0-13.0 parts by weight of surfactant, 14.0-17.0 parts by weight of oil, and 15.0-20.0 parts by weight of lauric acid were mixed and heated to a temperature of 50-60 ° C. to prepare an oily component (B). Next, the oily component (B) and the aqueous component (A) are a transparent skin cleanser composition obtained by stirring and mixing.

As the polyhydric alcohol used in the present invention, one or more of glycerin, propylene glycol, sorbitol, dipropylene glycol, 1, 3-butylene glycol, and mannitol may be selected. Among them, propylene glycol and 1, 3- Butylene glycol is most preferred.

The anionic surfactants used in the present invention include one of sodium lauryl sulfate and triethanolamine lauryl sulfate, ammonium lauryl sulfate, sodium laurate sulfate, cocamido propylbetaine, triethanolamine laurate sulfate, ammonium laurate sulfate or More may be chosen, the most preferred of which are sodium lauryl sulfate and triethanolamine lauryl sulfate. In addition, as the alkali metal salt according to the present invention, sodium hydroxide or potassium hydroxide or a mixture thereof may be used.

As the nonionic surfactant of the present invention, polyoxyethylene (20) ranolate, polyoxyethylene (40) ranolate, polyoxyethylene (3) oleate, choles-24, polyoxyethylene (5) ol One or more of the rate and polyoxyethylene (10) oleate may be selected, with polyoxyethylene (20) ranolate and polyoxyethylene (40) ranolate being most suitable.

In addition, the oil used in the present invention is one or more selected from isopropyl myristic acid, isopropyl palmitic acid, octyl palmitate, octyldodecanol or liquid paraffin, of which octyl palmitate is most suitable.

In the skin cleanser composition prepared as described above, the other component of the soap and the aqueous component (A) according to the neutralization reaction of lauryl acid, which is one of the oil component (B), and the alkali metal salt, which is one of the aqueous component (A), is used. The synergistic effect of the anionic surfactants not only improves the cleansing effect, but also the general cleaning effect is excellent due to the moisturizing effect of the polyhydric alcohol and the addition of oils to remove oily dirt and soften the skin. At the same time, it plays a role in removing powder and oily soil of makeup cosmetics.

In addition, the nonionic surfactant used in the present invention can make the skin cleanser composition as a microemulsion, such a microemulsion is significantly less particles than a conventional emulsion so that the composition penetrates deep into the skin deep into the skin. It will remove the remaining waste.

In addition, in the present invention, in order to enhance the effect of the skin cleaner composition, a perfume or a pigment for skin cleaner may be added.
