Abstract

A cationized glycerolated cellulose which, when blended in a hair cosmetic, is able to impart excellent smoothness and its long-lasting feeling at the time of rinsing and to impart a moist feeling and softness to the hair after drying and, when blended in a skin cleanser, is able to impart an excellent moisturizing feeling after drying; a surfactant composition containing the same; and a hair cosmetic composition and a skin cleanser composition each containing the surfactant composition, are provided. [1] A cationized glycerolated cellulose having a specified structure, which has a main chain derived from an anhydroglucose, wherein a degree of substitution of a cationized alkylene oxy group per the anhydroglucose unit is from 0.01 to 0.18, and a degree of substitution of a glycerol group per the anhydroglucose unit is from 0.5. to 5.0; [2] a surfactant composition containing the above-described cationized glycerolated cellulose, a surfactant, and water; [3] a use of the above-described surfactant composition as a hair cosmetic composition and a skin cleanser composition; and [4] a hair cosmetic composition and a skin cleanser composition each containing the above-described cationized glycerolated cellulose, a surfactant, and water, are disclosed.
