Abstract: Embodiments of the present disclosure are directed towards formulated polyol compositions that include a first polyether polyol having an average hydroxyl number from 112 to 280 mg KOH/g, a second polyether polyol having an average hydroxyl number from 18.5 to 51 mg KOH/g, a third polyether polyol having an average hydroxyl number from 20 to 70 mg KOH/g, and at least one of: fourth polyether polyol having an average hydroxyl number from 112 to 280 mg KOH/g; and a methoxypolyethylene glycol having an average hydroxyl number from 56 to 190 mg KOH/g.

Abstract: The present invention provides cooling, substantially formaldehyde and alkylphenylethoxylate (APEO) free aqueous coating compositions of a soft acrylic or vinyl copolymer binder comprising from 1.8 to 5 wt.%, based on the total weight of monomers used to make the copolymer, of an ethylenically unsaturated acid functional group containing monomer, in copolymerized form, and, in copolymerized form, an adhesion promoting ethylenically unsaturated monomer; an aqueous encapsulated PCM (phase change material) having a crosslinked acrylic shell; a nonionic associative thickener, such as a polyurethane associative thickener; and a softener. The aqueous coating compositions have a pH ranging from 7 to 8 and a solids content as high as 70 wt.% and provide soft coatings for viscoelastic polyurethane foams.

Abstract: Very soft, launderable polyurethane foams for pillow and other bedding applications are made using a quasi-prepolymer of diphenylmethane diisocyanate and a polyether polyol having a high oxyethylene content. The quasi-prepolymer is reacted with isocyanate-reactive components that include a certain monoalcohol but is devoid of or nearly devoid of a polyether polyol having a high oxyethylene content.
