Polyurethane dispersions for use in personal care products
摘要：
The invention relates to an aqueous polyurethane dispersion suitable for use in personal care products, the dispersed polyurethane comprising the reaction products of: A) a prepolymer according to the formula: wherein R1 represents a bivalent radical of a dihydroxyl functional compound, R2 represents a hydrocarbon radical of an aliphatic or cycloaliphatic polyisocyanate, R3 represents a radical of a low molecular weight diol, optionally substituted with ionic groups, n is from 0 to 5, and m is >1; B) at least one chain extender according to the formula: H2N—R4—NH2 wherein R4 represents an alkylene or alkylene oxide radical not substituted with ionic or potentially ionic groups; and C) at least one chain extender according to the formula: H2N—R5—NH2 wherein R5 represents an alkylene radical substituted with ionic or potentially ionic groups.
