This invention relates to hydrophilic, odorant-containing foam compositions having improved release ability of the odorant abetted by incorporating the odorant into a non-volatile, water insoluble oil or wax medium which is added to an aqueous reactant prior to reacting the aqueous reactant with a hydrophilic, isocyanate-terminated prepolymer to form a polyurethane foam.
