Decorative cosmetic preparations
View Patent ↗Decorative cosmetic preparations that contain water-soluble β-(1,3) glucans, which have intact β-(1,3) side-chains and are free from repetitive β-(1,6) linkages and a method of producing the same are disclosed.
1. A decorative cosmetic preparation comprising a water-soluble β(1–3)-glucan having side chains wherein the side chains exclusively show β-(1,3) linkages as well as additional auxiliary substances and additives.
2. The decorative cosmetic preparation of claim 1 wherein said water-soluble β-glucan is comprised in said preparations in amounts of 0.1 to 5% by weight, based on the total amount of agents in said preparation.
3. The decorative cosmetic preparation of claim 1 wherein said glucans are obtained from yeasts of the family Saccharomyces.
4. The decorative cosmetic preparations of claim 1 wherein said additional auxiliaries and additives are members of the groups comprising oil bodies, emulsifiers, hyperfatting agents, consistency substances, thickening agents, polymers, silicone compounds, fats, waxes, stabilizing agents, biogenic active substances, deodorants, swelling agents, UV light protection agents, antioxidants, organic and inorganic colour pigments, hydrotropes, preservatives, solubilizing agents, perfume oils, colouring agents and other auxiliaries and agents which are typically part of such preparations.
5. A method of producing decorative cosmetic preparations comprising adding a water soluble β-glucan comprising a main chain of β-(1,3)-linked glucose molecules and side-chains being linked to said main chain by β-(1,6) linkages, and where said side chains comprise β-(1,3) linked glucose molecules, to additional auxiliary substances and additives.
6. The method according to claim 5 wherein said water-soluble β-glucan is comprised in said preparations in amounts of 0.1 to 5% by weight, based on the total amount of auxiliary substances and additions in said preparations.
7. A method of treating wrinkles in the skin comprising applying to the skin a preparation comprising a water soluble β(1–3) glucan having side chains wherein the side chains exclusively show (1–3) linkages.
8. The method according to claim 7 wherein the preparation contains additional auxiliary substances and additives.
9. The method according to claim 7 wherein the preparation comprises said water soluble glucan in amounts of 0.1 to 5% by weight based on the weight of the preparation.
10. A method of maintaining moisture in the skin comprising applying to the skin a preparation comprising applying to the skin a water soluble β(1–3) glucan wherein the side chains exclusively show (1–3) linkages.
11. The method according to claim 10 wherein the preparation contains additional auxiliary substances and additives.
12. The method according to claim 10 wherein the preparation comprises said water soluble glucan in amounts of 0.1 to 5% by weight based on the weight of the preparations.
