Shampoo preparations
The invention relates to aqueous compositions comprising an anionic surfactant and a hyperbranched polyesteramide having at least one quaternized amine endgroup. 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. A method of treating hair to increase the volume thereof comprising applying a composition to said hair, the composition comprising an anionic surfactant, an amphoteric or zwitterionic surfactant and an effective amount of a hyperbranched polyesteramide having at least one quaternized amine end-group, wherein the hyperbranched polyesteramide having at least one quaternized 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 optionally also contain oxygen groups, a dicarboxylic acid or a cyclic anhydride thereof and diisopropanolamine followed by quaternization of the amino groups.
2. The method of claim 1 , wherein the aqueous composition is a volumizing shampoo preparation.
3. The method of 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. The method of 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. The method of 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. The method of claim 1 , wherein the ratio of the anionic surfactant to the hyperbranched polyesteramide having at least one quaternized amine end-group is in the range of 10 to 1 to 5 to 1.
7. The method of claim 1 , wherein the quaternized amine end-groups are selected from quaternized di(m)ethylaminoethyl, di(m)ethylaminopropyl, di(m)ethylaminohexyl and/or N-methylpiperazinyl groups.
8. The method of claim 1 , wherein the degree of quaternization of the amine end-groups is in the range of about 80 to 100%.
9. The method of claim 1 , wherein the amount of the hyperbranched polyesteramide having at least one quaternized amine end-group is in the range of 0.05-10 wt % based on the total weight of the composition.
10. The method of claim 1 , wherein the amphoteric or zwitterionic co-surfactant is cocamidopropyl betaine.
11. The method of claim 1 , wherein an additional amount of a hydrotrope is present.
12. The method of claim 11 , wherein the hydrotrope is sodium xylene sulfonate.
