Abstract: Embodiments of the present invention provide a foaming alcohol-based hand sanitizer having good foaming and virucidal characteristics by combining a linear siloxane polyether having a siloxane backbone with between 20 and 40 repeating siloxane units, two polyethylene glycol backbones each having between 10 and 20 repeating ethylene oxide units, and two polypropylene glycol backbones each having between 0 and 10 propylene oxide units, an alcohol such as ethanol or isopropanol, and water, where the hand sanitizer comprises between 0.01% and 5% linear siloxane polyether, more than 85% alcohol, and the balance is water.

Abstract: An epoxy-functionalized polyorganosiloxane toughener providing toughening properties for thermosetting resins is described. The epoxy-functionalized polyorganosiloxane toughener is an epoxy-functionalized siloxane polyether with a siloxane backbone, at least one epoxy-containing alkyl chain, and at least one alkoxyl polyether chain, each said at least one epoxy-containing alkyl chain and at least one alkoxyl polyether chain grafted to the siloxane backbone. Also disclosed is a thermosetting resin-based composition comprising the epoxy-functionalized polyorganosiloxane toughener of claim 1 and at least one of an epoxy resin, a hardener, and an accelerator.

Abstract: A novel phosphate polyol formulation is described, comprising a polyester polyol, a flame retardant comprising a phosphate polyol, a blowing agent, a catalyst, a surfactant, and a fire-retardant aromatic isocyanate. A further embodiment includes a phosphorus compound, such as a phosphate, a phosphate ester, or an alkyl phosphate such as triethyl phosphate.
