Active ingredient that is obtained from Candida saitoana and cosmetic use for detoxifying skin cells
View Patent ↗The object of the invention is the use of Candida saitoana or an active ingredient that is obtained from Candida saitoana as a cosmetic active ingredient, in particular for the detoxification of skin cells. The invention also relates to an active ingredient that is obtained from Candida saitoana , to a production process, as well as to cosmetic compositions that contain this active ingredient, and to a cosmetic personal care process for improving the surface condition of dull and intoxicated skin.
1. A cosmetic method for activating the autophagy of skin cells, comprising applying to the skin an effective amount of a cosmetic active ingredient, the active ingredient being an enzymatic hydrolysate of Candida saitoana comprising carbohydrate compounds, at least a portion of the carbohydrates being alpha-glucan oligosaccharides having a molecular weight between 180 Da to 1500 Da.
2. The cosmetic method according to claim 1 , wherein activating the autophagy of the skin cells comprises stimulating LC3 protein synthesis in said skin cells.
3. The cosmetic method according to claim 1 , wherein the method comprises detoxification of said skin cells.
4. The cosmetic method according to claim 1 , wherein the method comprises improving the complexion brightness and/or smoothing the skin microrelief.
5. A cosmetic process for personal care of human skin, comprising topically applying to the skin a composition comprising an effective amount of an active ingredient, the active ingredient being an enzymatic hydrolysate of Candida saitoana comprising carbohydrate compounds, at least a portion of the carbohydrates being alpha-glucan oligosaccharides having a molecular weight between 180 Da to 1500 Da,
wherein the effective amount improves the surface condition of dull and/or intoxicated skin.
6. A cosmetic process for personal care of the human skin, comprising topically applying to the skin a composition comprising an effective amount of an active ingredient, the active ingredient being an enzymatic hydrolysate of Candida saitoana comprising carbohydrate compounds, at least a portion of the carbohydrates being alpha-glucan oligosaccharides having a molecular weight between 150 Da to 1800 Da,
wherein the effective amount smoothes the microrelief of the skin and/or to improves complexion brightness.
7. The cosmetic method according to claim 1 , wherein at least 20% of the carbohydrates are alpha-glucan oligosaccharides having a molecular weight of between 180 Da to 1500 Da.
8. The cosmetic method according to claim 1 , wherein the carbohydrate compounds comprise:
50-60% monosaccharides in the form of glucose, mannose and N-acetyl glucosamine, and
40-50% oligosaccharides having a mean degree of polymerization of 5, of which 60-70% are α-glucan oligosaccharides and 30-40% are β-glucan oligosaccharides (β-1,3 and β-1,6).
