Contain breathable polyurethane vertical moisture permeability is about 500 grams / m 2/24 hours The polyurethane, the amount of poly (alkylene oxide comprises from about 12% to about 80% by weight of (a) the polyurethane ) Side chain unit, (i) the alkylene oxide group in the poly (alkylene oxide) side chain unit has 2 to 10 carbon atoms and is unsubstituted, substituted, or unsubstituted and substituted. And (ii) at least about 50% by weight of the alkylene oxide group is ethylene oxide, and (iii) the amount of the side chain unit is a poly (alkylene oxide) side chain unit depending on the molecular weight of the side chain unit And (b) a hair fixative composition comprising poly (ethylene oxide) backbone units in an amount comprising less than about 25% by weight of the polyurethane. |
