    Abstract: A high-resiliency polyurethane foam comprises the reaction product of an isocyanate and an isocyanate-reactive component. The isocyanate-reactive component comprises a first polyether polyol in an amount of greater than about 5 parts by weight and a second polyether polyol in an amount of less than about 80 parts by weight, with parts by weight based on the total weight of the isocyanate-reactive component. The high-resiliency polyurethane foam has a resilience of about 45 to about 70% when tested in accordance with ASTM D3574-11. A method of forming a high-resiliency polyurethane foam includes the steps of providing the isocyanate and the isocyanate-reactive component and reacting the isocyanate and the isocyanate-reactive component.

    IPC: C09K3/18

    Abstract: Described herein is an ice melting composition that includes at least one solvent, at least one deicing agent, and at least one additive. Possible additives include ionic liquids, deep eutectic solvents, dispersants and combinations thereof. The composition exhibits an increased saturation point due to the addition of the additives thereby reducing or eliminating precipitation of the deicing agent at low temperatures. Also described herein are methods of melting ice or preventing ice from forming on a surface. The methods include applying the ice melting composition to the surface either before or after ice forms.

    Abstract: An aqueous polymer dispersion with an average particle size of less than 1000 nm comprising a) a polymer carrier prepared by heterophase radical polymerization of at least one ethyleni-cally unsaturated monomer in the presence of b) an oil-soluble organic UV absorber selected from the class of p-aminobenzoic acid derivatives; salicylic acid derivatives; benzophenone derivatives; diphenyl acrylate derivatives; benzofuran derivatives; polymeric UV absorbers, comprising one or more organosilicon radicals; cinnamic acid derivatives; camphor derivatives; s-triazine derivatives; trianilino-striazine derivatives; menthyl anthranilates; and benzotriazole derivatives; wherein the weight ratio of the oil-soluble organic UV absorber (b) to polymer carrier (a) is greater than 50 parts UV absorber per 100 parts of carrier; and c) a surfactant selected from c1) a nonionic surfactant selected from c11) the condensation product of a C6 to C18 fatty alcohol or C6 to C18 fatty acid and a mono- or disaccharide; and c2) an anionic surfactant selected from c21) sulfosuccinates and sulfosuccinamates; c22) fatty alcoholates; and c23) mixtures of phosphoric acid esters and fatty alcohols having from 6 to 18, preferably from 8 to 10, carbon atoms. The aqueous polymer dispersions show unexpectedly high sunscreen effects and a positive skin feeling. They have excellent anti-pollen, ant-dust and anti-oxidant performances in sun screen compositions.
