Volume up shampoos

Abstract

The invention relates to aqueous compositions comprising an anionic surfactant and a hyperbranched polyesteramide having at least one quarternized amine end-group. The compositions, in particular in the form of shampoo preparations are suited for increasing the volume of hair treated therewith. Furthermore, such compositions provide styling attributes and increase the wet-combability of hair.

1 . An aqueous composition comprising an anionic surfactant and an effective amount of a hyperbranched polyesteramide having at least one quarternized amine end-group. 
     
     
         2 . A composition according to  claim 1 , wherein the aqueous composition is a volumizing shampoo preparation. 
     
     
         3 . A composition according to  claim 1 , wherein the anionic surfactant is selected from sodium lauryl sulfate, ammonium lauryl sulfate, sodium lauryl ethersulfate, ammonium lauryl ethersulfate, sodium lauroyl sarconisate, sodium oleylsuccinate, ammonium lauryl sulfosuccinate, sodium dodecylbenzol sulfonate and/or triethanolamido decylbenzol sulfonate. 
     
     
         4 . A composition according to  claim 3 , wherein the anionic surfactant is selected from sodium lauryl sulfate, ammonium lauryl sulfate, sodium lauryl ether sulfate and/or ammonium lauryl ether sulfate. 
     
     
         5 . A composition according to  claim 1 , wherein the amount of the anionic surfactant is in the range of 7 to 25 wt.-% based on the total weight of the composition. 
     
     
         6 . A composition according to  claim 1 , wherein the ratio of the anionic surfactant to the hyperbranched polyesteramide having at least one quarternized amine end-group is in the range of 10 to 1 to 5 to 1. 
     
     
         7 . A composition according to  claim 1 , wherein the hyperbranched polyesteramide having at least one quarternized amine end-group is obtainable by condensation of a dialkylamine of the general formula HN(R 1 R 2 ) and/or an alcohol functional amines of the general formula HO—R 3 —N(R 1 R 2 ), wherein R 1  and R 2  are di-(C 1-20 -alkyl)amino-C 1-20 -alkyl groups or R 1  and R 2  together form a N-heterocyclic ring and R 3  is C 1-20 -alkyl which might also contain oxygen groups, a dicarboxylic acid or a cyclic anhydride thereof and diisopropanolamine followed by quaternization of the amino groups. 
     
     
         8 . A composition according to  claim 1 , wherein the quarternized amine end-groups are selected from quaternized di(m)ethylaminoethyl, di(m)ethylaminopropyl, di(m)ethylaminohexyl and/or N-methylpiperazinyl groups. 
     
     
         9 . A composition according to  claim 1 , wherein the degree of quaternization of the amine end-groups is in the range of about 80 to 100%. 
     
     
         10 . A composition according to  claim 1 , wherein the amount of the hyperbranched polyesteramide having at least one quarternized amine end-group is in the range of 0.05-10 wt. % based on the total weight of the composition. 
     
     
         11 . A composition according to  claim 1 , wherein an additional amount of an amphoteric or zwitterionic co-surfactant is present. 
     
     
         12 . A composition according to  claim 11 , wherein the amphoteric or zwitterionic co-surfactant is cocamidopropyl betaine. 
     
     
         13 . A composition according to  claim 1 , wherein an additional amount of a hydrotrope is present. 
     
     
         14 . A composition according to  claim 13 , wherein the hydrotrope is sodium xylene sulfonate. 
     
     
         15 . A method of treating hair in which a composition as described in  claim 1 , is applied to the hair. 
     
     
         16 . Use of a composition according to  claim 1 , for increasing the volume of hair.
