Abstract
A composition containing a cooling-sensation imparting substance and a cationic surfactant results in an excellent cooling sensation effect. A composition additionally containing vanilylalkyl ether, wherein the alkyl group has 1 to 6 carbon atoms, is also effective as a composition for improving cooling sensation effect. The present composition for improving cooling sensation effect improves cooling sensation effect while also sustaining that effect. In particular, the present invention provides a composition for improving cooling sensation effect that is able to impart a cooling sensation effect and sustain that effect when used after washing the hair using a shampoo containing no cooling sensation substance or a shampoo containing only a small amount of cooling sensation substance.
