Title:

CATION-MODIFIED ALGINIC ACID DERIVATIVE AND COSMETIC PREPARATION COMPOSITION CONTAINING THE SUBSTANCE

Document Type and Number:

WIPO Patent Application WO/2004/099259

Kind Code:

A1

Abstract:

A cation-modified alginic acid derivative. When incorporated into cosmetic preparation compositions such as a hair treatment composition and a cosmetic preparation composition for the skin, the derivative improves lathering and the feel of the lather as a lather quality. When incorporated into hair treatment compositions, the derivative produces an excellent conditioning effect and gives a satisfactory finish feeling. When incorporated into cosmetic preparation compositions for the skin, such as a body detergent, the derivative gives an improved use feeling due to its conditioning effect. The cation-modified alginic acid derivative is obtained by incorporating a specific quaternary nitrogen-containing group into part of the hydroxy groups contained in an alginic acid derivative which is a natural polysaccharide contained in the form of a calcium salt in the cell walls of a seaweed belonging to brown algae (scientific name: Phaeophyceae), e.g., tangle or wakame seaweed, and is a polymer made up of uronic acid units derived from L-glucuronic acid and D-mannuronic acid and bonded to each other through 1,4-glycoside bonds. Also provided is a cosmetic preparation composition containing the cation-modified alginic acid derivative.
