Cosmetic preparations
The invention relates to cosmetic preparations containing (a) water-soluble β-(1,3) glucans, substantially devoid of β-(1,6) links, and (b) chitosans. The agents are suitable for hair care and personal hygiene and can also be used for sun protection.
1 . A cosmetic preparation, comprising:
(a) water soluble β-(1,3) glucans, with naturally intact β-(1,3) side chains, wherein the side chains comprise β-(1,3) linkages or 0-4 consecutive β-(1,6) linkages, and (b) chitosans.
2 . The preparation of claim 1 , wherein the chitosans have a molecular weight of around 50,000 to 500,000 Daltons.
3 . The preparation of claim 1 , wherein the chitosans have a molecular weight of around 800,000 to 1,200,000 Daltons.
4 . The preparation of claim 1 , wherein said preparation comprises carboxylated chitosans.
5 . The preparation of claim 1 , wherein said preparation comprises succinilated chitosans.
6 . The preparation of claim 1 , wherein said preparation comprises
(a) 0.01 to 25% by weight of said β-(1,3) glucans, and
(b) 0.01 to 5% by weight of chitosans,
provided that the stated amounts are supplemented with water as well as optionally other auxiliaries and additional agents up to 100% by weight.
7 . A method of treating aging of the skin of a patient in need thereof comprising applying to the skin a preparation comprising:
(a) water soluble β-(1,3) glucans with naturally intact β-(1,3) linked side chains comprising β-(1,3) linkages or 0-4 consecutive β-(1,6) linkages, and
(b) chitosans.
8 . The method of claim 7 , wherein the chitosans have a molecular weight of around 50,000 to 500,000 Daltons.
9 . The method of claim 7 , wherein the chitosans have a molecular weight of around 800,000 to 1,200,000 Daltons.
10 . The method of claim 7 , wherein said method comprises carboxylated chitosans.
11 . The method of claim 7 , wherein said method comprises succinilated chitosans.
12 . The method of claim 7 , wherein said method comprises
(a) 0.01 to 25% by weight of said β-(1,3) glucans, and
(b) 0.01 to 5% by weight of chitons,
provided that the stated amounts are supplemented with water as well as optionally other auxiliaries and additional agents up to 100% by weight.
13 . A method of treating rough skin on a patient in need thereof, comprising applying to the skin a composition comprising:
(a) water soluble β-(1,3)-glucans, with naturally intact β-(1,3) linked side chains comprising β-(1,3) linkages or consecutive β-(1,6) linkages, and
(b) chitosans.
14 . The method of claim 13 , wherein the chitosans have a molecular weight of around 50,000 to 500,000 Daltons.
15 . The method of claim 13 , wherein the chitosans have a molecular weight of around 800,000 to 1,200,000 Daltons.
16 . The method of claim 13 , wherein said method comprises carboxylated chitosans.
17 . The method of claim 13 , wherein said method comprises succinilated chitosans.
18 . The method of claim 13 , wherein said method comprises
(a) 0.01 to 25% by weight of said β-(1,3) glucans, and
(b) 0.01 to 5% by weight of chitosans,
provided that the stated amounts are supplemented with water as well as optionally other auxiliaries and additional agents up to 100% by weight.
