Problems solved by technology

However, due to the high melting point and easy crystallization of protective bases such as ceramide or glyceryl ceramide, it cannot be added in large amounts
Moreover, the small amount of protective base added is difficult to penetrate into the hair, so there is no way to supply sufficient protective base to the hair
Therefore, existing hair cleansers have the problem of not being able to give full play to the performance of the added protective base agent

Abstract

Provided is a hair cleansing composition containing (A) an amphipathic amide lipid, (B) an anionic surfactant and (C) an organic or inorganic acid, or a salt thereof, and having a pH of from 1 to 4.5 when diluted with water to 20 times the weight. The hair cleansing composition of the present invention has advantages including protecting hair from physical or chemical stimulation and preventing split ends or breakage of hair without impairing the cleansing ability and feeling upon use, imparting hair with a pleasant feeling to the touch and moisture retention properties such as natural smoothness, moist feeling, and suppleness which healthy hair inherently possesses, and has excellent stability.

Description

technical field [0001] The present invention relates to acidic hair cleansers containing amphiphilic amide lipids. Background technique [0002] Since hair is often subjected to physical stimulation caused by daily hair care such as heat from a hair dryer and hair combing, and chemical stimulation caused by shampooing, perming, hair dyeing, bleaching, etc., there may be parts of ingredients and structures The state of damage such as defects. On the other hand, changes in hair texture that occur with age are the main cause of this accelerated damage and loss of original softness in healthy hair. [0003] The protection and repair of damaged hair is usually carried out in the form of supplementing the damaged components, structures and the like. It is generally considered that the interaction (affinity) of the protective base and the hair is important for the discovery of protective and repairing functions. Now, a method in which sphingolipids or protein derivatives are use...
