Abstract
An aqueous conditioner formulation for thermally styled hair is provided, including: an aqueous carrier; and a modified carbohydrate polymer, comprising a cellulose ether base material functionalized with (i) trialkyl ammonium moieties of formula (I) wherein R1 is independently a C1-7 alkyl group and wherein the modified carbohydrate polymer has a Kjeldahl nitrogen content, TKN, corrected for ash and volatiles, of 0.75 to 2.5 wt %; and (ii) hydrophobic substituents having 16 carbon atoms; wherein the modified carbohydrate polymer comprises 0.005 to 1.5 wt %, based on weight of the cellulose ether base material, of the hydrophobic substituents; wherein the hydrophobic substituents are randomly distributed across the backbone of the cellulose ether base material; wherein the cellulose ether base material has a weight average molecular weight, MW, of >1,000,000 Daltons; and wherein the modified carbohydrate polymer has <0.001 wt %, based on weight of modified carbohydrate polymer, of crosslinking units.
