Title:
多糖誘導体
Document Type and Number:
Japanese Patent JP3973904
Kind Code:
B2
Abstract:
Polysaccharide derivatives derived from a polysaccharide or a derivative thereof by substituting a part or all of the hydrogen atoms of the hydroxyl groups of the polysaccharide or the derivative thereof with the groups represented by the following formula (1): -E<1>-(OA)n-E<2>-R wherein E<1> represents a divalent saturated C1-6 hydrocarbon group which may be substituted with one or more hydroxyl groups or oxo groups, n stands for a number of from 8 to 300, n numbers of As may be the same or different and each independently represent a divalent saturated C1-6 hydrocarbon group, E<2> represents an ether bond or an oxycarbonyl group, and R represents a C4-30 alkyl group which may be substituted with one or more hydroxyl groups, in which the H(s) of one or more hydroxy groups in each of said groups (1) may be further substituted with the groups (1); thickeners and emulsifiers comprising these polysaccharide derivatives; as well as aqueous compositions containing said polysaccharide derivatives. The polysaccharide derivatives of the present invention are excellent in water solubility and have such a rheological characteristic that the viscosity thereof increases at high temperatures, whereby they are very useful as a thickener exhibiting an excellent handling property at low temperatures and a sufficient thickening effect at high temperatures, as an emulsifier exhibiting an excellent emulsifying action allowing hydrophobic compounds to exist very stably in water, and also as a thickening and stabilizing agent for various toiletry products such as viscous bath preparations, massaging cosmetic preparations, shower preparations, skin care preparations, hair washing preparations, body washing preparations, garment detergents, garment finishing agents and hard surface cleaning agents.
