Abstract:
1. A gelled water-in-oil microemulsion for hair treatment comprising: (a) an oil phase comprising: (i) 10 to 95% by wt. based on total weight of the gelled microemulsion of a first oily component which is one or more glyceride fatty esters, and (ii) 5 to 95% by wt. based on total weight of the gelled microemulsion of a second oily component which is one or more hydrocarbon oils of average carbon chain length less than 20 carbon atoms; (b) a hydrophilic phase comprising: (i) about 2 to 10% by wt. based on total weight of the gelled microemulsion of water, (ii) a nonionic emulsifier which is an ethoxylated alcohol having an HLB of at least 6, and (iii) 0.05 to 4% by wt. of a hair styling agent or hair conditioning agent based on total weight of the gelled microemulsion, and (c) 0.1 to 3% by wt. based on total weight of the gelled microemulsion of a gelling agent, wherein said gelling agent is an n-acyl glutmic acid amide corresponding to the following formula: in which R 1 is an aliphatic hydrocarbon radical having from 12 to 22 carbon atoms, and R 2 is an aliphatic hydrocarbon radical having from 4 to 12 carbon atoms.
