An anti-dandruff composition for regulating scalp oil balance

Abstract

A dandruff removing composition, comprising a cosmetically acceptable carrier, a scalp barrier protection agent and a scalp sebum adjusting agent; the scalp barrier protection agent comprises 0.001 wt% to 1.0 wt% of N-palmitoylethanolamine, 0.01 wt% to 20 wt% of N-acetylethanolamine and 0.01 wt% to 2 wt% of tetrahydropyrimidine or hydroxytetrahydropyrimidine, a weight ratio of the N-palmitoylethanolamine and the N-acetylethanolamine being 1:100. The scalp sebum adjusting agent comprises 0.1 wt% to 15 wt% of trimethylglycine salicylate and 0.05 wt% to 3 wt% of vitamin B12.

Description

technical field [0001] The invention belongs to the field of daily chemicals, and in particular relates to a composition for reducing dandruff by regulating scalp sebum balance. Background technique [0002] Dandruff arises from the scalp. It is a large amount of desquamation caused by the excessive proliferation of scalp keratinocytes. About 60% of adults in my country are troubled by dandruff to varying degrees, and 15% of them have very serious symptoms. At present, although personal care products claiming anti-dandruff function emerge in an endless stream, 70% of people who use anti-dandruff products think that the effect is not ideal. [0003] The pathogenesis of dandruff is not yet clear, there are several theories for the cause of dandruff, the most important of which is the mechanism of action of Malassezia. A large number of studies have proved that Malassezia is closely related to the occurrence and severity of dandruff. Malassezia bacteria multiply on the scalp ...

AI Technical Summary

Problems solved by technology

The lack of scalp horny barrier function is easy to stimulate and cause the imbalance of scalp oil secretion, which leads to the invasion of various bacteria and fungi, all of which will make the phenomenon of dandruff and itching capricious and not easy to solve the root cause

[0007] In addition, some studies have reported that on a healthy scalp, Malassezia and humans live in harmony, so the susceptibility of the scalp and the amount of oil secretion in the scalp will maintain a relative balance. aware

Once this balance is broken, Malassezia will multiply abnormally, causing epidermal metabolism to accelerate, and epidermal cells will fall off in groups and large pieces

Conversely, the repeated outbreaks of dandruff severely damage the scalp cell layer, and the thinned scalp cell layer loses its barrier function, making the dandruff phenomenon recurrent and difficult to solve
