Abstract
Lactic acid esters of an .alpha.-branched fatty acid possessing an excellent hair conditioning effect are disclosed. Typical example is sodium 2-heptylundecanoyl acid lactate prepared by the reaction of 2-heptylundecanoic acid and lactic acid in the presence of an alkali such as sodium hydroxide. This compound gives a shampoo composition in conjunction with an anionic surface active agent, and a hair rinse composition when a quaternary ammonium salt is formulated. The compositions have excellent conditioning effects on use such as good slipperiness and hair curling formation or retention performance.
