Summary Suggested is a ginger extract, comprising (a) 25 to 30 % b.w. [6]-gingerol (b) 5 to 10 % b.w. [8]-gingerol (c) 5 to 10 % b.w. [10]-gingerol (d) 1.5 to 4 % b.w. [6]-shogaol (e) 0.3 to 1.3 % b.w. [8]-shogaol; (f) 0.03 to 1 % b.w. [10]-shogaol; (g) 0.01 to 1 % b.w. zingerone, on condition that the amount of gingerols sums up to 35 to 50 % b.w. and the amount of shogaols sums up to 1.5 to 6 % b.w.

Description

technical field

[0001] The present invention belongs to the field of cosmetics, in particular, the present invention relates to new ginger extracts for use in skin care and hair care products. Background technique

[0002] Stem cells located near the hair follicles cause the skin renewal system to gradually slow down with age. As a result, the complexion changes from bright and lustrous to dull, the skin surface changes from smooth to wrinkled, and the skin changes from dense to thin (Grove et al., J Gerontol 1983, 38(2):137-42). Hair, which is an appendage of the skin, is also affected by stem cell aging: the hair color changes from gray to white, the hair structure changes to a thin and brittle structure, and hair renewal gradually decreases, leading to hair loss and baldness. The mapping of specific stem cell niches follows years of research to identify mechanisms that lead to stem cell decline and, for the first time, to protect these progenitor cells from proliferation...
