Non-weighing hair preparations

Abstract

An agent for treating keratin-comprising fibers, in particular human hair, which includes in a cosmetic carrier at least one cyclic siloxane, at least one C8 to C30 alkyl PEG/PPG dimethicone, and at least one cationic protein hydrolysate.

What is claimed is: 
     
         1 . A hair treatment agent comprising, based on its weight,
 a) at least 70 wt. % water,   b) 0.1 to 1.5 wt. % of at least one silicone-based water-in-oil emulsifier from the group of C8 to C30 alkyl PEG/PPG dimethicone,   c) 1 to 10 wt. % cyclic siloxane, and   d) at least 0.1 to 5 wt. % of a cationic protein hydrolysate,   wherein the hair treatment agent is characterized to form, within 10 minutes of mixing, a two-phase composition that has a lower aqueous phase and an upper oil phase.   
     
     
         2 . The agent according to  claim 1 , wherein the at least one silicone-based water-in-oil emulsifier from the group of C8 to C30 alkyl PEG/PPG dimethicones is included at a concentration ranging between 0.15 and 1.25 wt. %. 
     
     
         3 . The agent according to  claim 1 , wherein the cyclic siloxane is included at a concentration ranging between 1.5 and 9.5 wt. %. 
     
     
         4 . The agent according to  claim 1 , wherein the silicone-based water-in-oil emulsifier from the group of C8 to C30 alkyl PEG/PPG dimethicones is selected from lauryl, myristyl, cetyl, and/or stearyl PEG/PPG dimethicones. 
     
     
         5 . The agent according to  claim 1 , wherein the cationic protein hydrolysate is a plant-based cationic protein hydrolysate. 
     
     
         6 . The agent according to  claim 5 , wherein the cationic protein hydrolysate is a cationic wheat protein hydrolysate. 
     
     
         7 . The agent according to  claim 1 , wherein the agent comprises, based on its weight, 0.05 to 7.5 wt. % of one or more cationic polymers selected from the group consisting of:
 poly(methacryloyloxyethyltrimethylammonium chloride) (INCI: Polyquaternium-37),   quaternized cellulose derivatives (INCI: Polyquaternium-10),   cationic alkylpolyglycosides, cationized honey,   cationic guar derivatives,   polymeric dimethyldiallylammonium salts and copolymers thereof with esters and amides of acrylic acid and methacrylic acid,   copolymers of vinylpyrrolidone with quaternized derivatives of dialkylaminoalkyl acrylate and methacrylate,   vinylpyrrolidone-vinylimidazolium methochloride copolymers,   quaternized polyvinyl alcohol,   Polyquaternium-2,   Polyquaternium-7,   Polyquatemium-16,   Polyquatemium-17,   Polyquatemium-18,   Polyquaternium-24, and   Polyquaternium-27.   
     
     
         8 . A method for providing care to human hair, comprising:
 applying an agent according to  claim 1  onto the hair;   leaving the agent on the hair for a contact time from 10 to 600 seconds; and   rinsing the hair out.
