Description

  The present invention relates to a cosmetic, and more particularly to a cosmetic suitable for an emulsified cosmetic for removing horn plugs.

  It is widely known that horn plugs become pores of pores, become a hotbed of organisms such as ticks, and this causes various skin troubles and damages the appearance of the skin. It is common knowledge in the industry that the removal of horn plugs is indispensable for keeping skin healthy. Reflecting this situation, various cosmetics for removing horn plugs have been developed and sold. As such cosmetics, for example, a pressure-sensitive adhesive is applied on a support, and this is applied to a site where a square plug such as a nose is present, the pressure-sensitive adhesive is solidified, and then peeled off, What removes (for example, refer to Patent Document 1), what dissolves fatty acids fixing the horn plug to the skin by the solvent effect of the oil component, and removes the horn plug by physical squeezing (for example, Patent Document 2), cosmetics that solubilize fatty acids with alkali, loosen the structure of horn plugs, and remove them by physical rubbing (for example, see Patent Document 3). However, all of these methods have drawbacks such that the stimulation derived from the cosmetics is too strong, and the skin is easily damaged by rubbing or peeling. Among these methods, a technique that reduces the irritation by using an acylated amino acid ester by selecting an acylated amino acid ester for the one that uses the solvent effect has been developed and obtained a remarkable effect (for example, patents). However, in this method, the removal rate of horn plugs remains as one problem. An ester of dimer acid is a viscous oil and fat having excellent moisturizing properties, and is used in cosmetics for the purpose of moisturizing, but its effect on removing plugs is not known at all. (For example, see Patent Document 5, Patent Document 6, and Patent Document 7)

  On the other hand, cosmetics containing 1) one or more selected from esters of dimer acid and 2) two or more selected from esters of acylated amino acids are not known at all, It has not been known at all that a cleansing cosmetic having an excellent ability to remove horn plugs by taking such a configuration.
