Cationized glycerolated cellulose

摘要

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.

1. A surfactant composition comprising: a cationized glycerolated cellulose having a main chain derived from an anhydroglucose represented by the following general formula (1), 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, and a viscosity of a 1% by mass aqueous solution at 25° C. is from 10 to 10,000 mPa·s; a surfactant; water; and an oil, wherein the content of the oil is from 0.01 to 30% by mass, and the oil contains a silicone oil,wherein
each of R1, R2, and R3 independently indicates a substituent composed of one or more repeating units selected among the following formulae (2) to (5), or a hydrogen atom, provided that all of R1, R2, and R3 in the molecule are not a hydrogen atom at the same time; and n indicates an average polymerization degree of the main chain derived from an anhydroglucose and is a number of from 100 to 12,000,wherein
a repeating unit structure represented by the formula (2) or (3) indicates a cationized alkylene oxy group; a repeating unit structure represented by the formula (4) or (5) indicates a glycerol group; each of R4 to R9 independently indicates a linear or branched alkyl group having a carbon number of from 1 to 3; X− and Y− indicate an anion; r and s indicate any integer of from 0 to 3; and in the repeating unit structures represented by the formulae (2) to (5), the oxygen atom is bound to a hydrogen atom or a carbon atom of other repeating unit.
