Description

Composition for waving and straightening hair containing a compound TECHNICAL FIELD

The present specification relates to a composition for permanent wave and straightening containing a specific compound.

The principle of permanent wave and straightening on the hair is closely related to the structure and properties of the hair. Hair is composed of the epidermis, cortex, and medulla from the outermost layer. The keratin of hair is linked by a polypeptide made up of various amino acids, and between the polypeptide and the polypeptide is a high molecular substance with side chains such as cystine bonds, salt bonds, and hydrogen bonds, and the content of sulfur is higher than that of other proteins. .

Since hair is composed of keratin with this structure, it has elasticity and thus has the property of returning to its original state even when bent. The principle of permanent wave and permanent straightening is to form a desired wave or straighten it by temporarily losing the elasticity of the hair by cutting the side chain and then recombination to a new position.

According to this principle, the products of the permanent wavy and straightening agents composed of the first agent and the second agent are most widely used. In general, cystine bonds in hair are reduced with a reducing agent comprising thioglycolic acid, its salts, its esters, cysteine, its salts, or its acetyl derivatives. Here, by the reducing action of the first agent with an oxidizing second agent containing hydrogen peroxide or sodium bromate, the once cleaved side chain bonds are recombined to a new site to form wavy and straight hair. Alkaline agents, penetrants, stabilizers, wetting agents, wool agents, colorants, emulsifiers, fragrances, etc. are used to increase their effectiveness and usability.

These permanent waving and straightener formulations are carried out in harsh environments such as reducing cleavage of keratin bonds of hair by reducing agents and oxidizing agents, oxidizing agent binding, high-temperature heating under strong alkali, and double exposure by reducing agents and oxidizing agents. will entail damage.

In addition, there is irritation of the scalp due to pH and chemical action, and a stench due to material residue remains after the procedure.
