Abstract

The present invention refers to a cosmetic composition which, in particular, enables the perfume component resist wash off by water and sweat and to remain fixed on the skin for a long time watertightly. The cosmetic composition comprises fragrance and a fragrance-fixing complex consisting of 0.01-10% by weight of a hydrophobic, alcohol-soluble, carboxylated acrylates/octylacrylamide copolymer and 0.01-10% by weight of a hydrolyzed jojoba ester. Further the complex is able to significantly reduce the total amount of fragrances while giving the same scent feeling to the consumer.

Claims

1 - 23 . (canceled) 
     
     
         24 . A method of providing water-resistant fragrance, the method comprising:
 applying to skin a cosmetic composition with a watertight fragrance, the composition comprising: a) one or more fragrances, and b) 0.1 to 15% by weight of a fragrance-fixing complex comprising 0.01 to 10% by weight of a hydrophobic, alcohol-soluble, carboxylated acrylates/octylacrylamide copolymer and 0.01 to 10% by weight of a hydrolyzed jojoba ester, such that the one or more fragrances are resistant to wash off by water and sweat and remain fixed on the skin,   wherein all percents are related to the total weight of the cosmetic composition.   
     
     
         25 . The method of  claim 24 , wherein the composition further comprises an alcohol or an alcohol/water mixture. 
     
     
         26 . The method of  claim 24 , wherein the amount of the copolymer is in the range of 0.1 to 5% by weight. 
     
     
         27 . The method of  claim 26 , wherein the amount of the copolymer is in the range of 0.1 to 1% by weight. 
     
     
         28 . The method of  claim 24 , wherein the amount of the jojoba ester is in the range of 0.1 to 5% by weight. 
     
     
         29 . The method of  claim 28 , wherein the amount of the jojoba ester is in the range of 0.1 to 1% by weight. 
     
     
         30 . The method of  claim 24 , wherein said one or more fragrances are present in an amount ranging between 0.01 and 35% by weight. 
     
     
         31 . The method of  claim 30 , wherein said one or more fragrances are present in an amount ranging between 0.1 and 16% by weight. 
     
     
         32 . The method of  claim 31 , wherein said one or more fragrances are present in an amount ranging between 0.1 and 8% by weight. 
     
     
         33 . The method of  claim 24 , wherein said hydrolyzed jojoba ester is derived from the plant  Simmondsia chinensis  and has a saponification value according to the American Oil Chemists Society test procedure ACOS Cd 3-25 of max. 1 mg KOH/g, a iodine value according to the American Oil Chemists Society test procedure ACOS Cd Id-92 of between 14 and 17 g/100 g and a trans isomer value according to the American Oil Chemists Society test procedure ACOS Cd 14-95 of max. 0.1% by weight. 
     
     
         34 . The method of  claim 24 , wherein the complex is provided in a cosmetic product selected from perfumes, Eau de Toilettes, hair products, body care products, sun care products, antiperspirants, deodorants, detergents and products of color cosmetic. 
     
     
         35 . The method of  claim 24 , wherein the amount of the complex in the cosmetic product is in the range of 0.5 to 10% by weight. 
     
     
         36 . The method of  claim 24 , wherein the amount of the complex in the cosmetic product is in the range of 0.5 to 4% by weight. 
     
     
         37 . The method of  claim 24 , wherein the amount of the complex in the cosmetic product is in the range of 0.5 to 1.5% by weight. 
     
     
         38 . The method of  claim 24 , wherein the composition further comprises cosmetic auxiliaries, cosmetic actives, and carrier substances as commonly used in cosmetic compositions. 
     
     
         39 . The method of  claim 24 , wherein the amount of the copolymer is in the range of 0.1 to 5% by weight, the amount of the jojoba ester is in the range of 0.1 to 5% by weight, and said one or more fragrances are present in an amount ranging between 0.01 and 35% by weight. 
     
     
         40 . The method of  claim 24 , wherein the amount of the copolymer is in the range of 0.1 to 1% by weight, the amount of the jojoba ester is in the range of 0.1 to 1% by weight, and said one or more fragrances are present in an amount ranging between 0.1 and 16% by weight. 
     
     
         41 . The method of  claim 24 , wherein said jojoba ester and said copolymer constitute a separately prepared complex in the relation 1:1-4 of jojoba ester: polymer. 
     
     
         42 . The method of  claim 24 , wherein said jojoba ester and said copolymer constitute a separately prepared complex in the relation 1:1.2-2.8 of jojoba ester: polymer.
