There is provided a composition comprising covalently linked segments of for example, polycaprolactone and polyethylene glycol that are linked by a cross-linker. Such a composition foams in the presence of a catalyst and a solution containing an oxygen forming chemical like hydrogen peroxide. The foamed composition retains oxygen for delivery to, for example, a wound, where it aids in healing.

Foams for oxygen delivery to wounds

Self-assembly is defined as the ability of an active ingredient (AI), when mixed with a polymer or polymers (solid or liquid state), to form either a complex or a strong attraction with the polymer/polymers, which influences the controlled release of the total system. This AI-polymer interaction or strong attraction can form in the solid state or in solution. The AI-polymer interaction also can form when applied to a filter paper, soil, seeds, or plant vegetation substrates, where the AI and polymer self-assembles into an AI-polymer-substrate matrix or complex that influences how the AI releases from the complex or matrix in a controlled manner.

A deicing/anti-icing fluid includes at least 20% by weight of a freeze point depressant selected from short chain polyols having 2 to 5 carbon atoms. The fluid further includes at least 10% by weight of water, a thickener, and a surfactant. The fluid meets the requirements of SAE/AMS 1428 or its revisions for a non-Newtonian, Type II, III, or IV aircraft deicing/anti-icing fluid.

Compositions for deicing/anti-icing

A non-toxic deicing/anti-icing fluid includes at least 20% by weight of a freeze point depressant selected from short chain polyols having 3 to 5 carbon atoms. The fluid further includes at least 10% by weight of water, a thickener, a surfactant, and a pH moderator. The fluid meets the requirements of SAE/AMS 1428 or its revisions for a non-Newtonian, Type II, III, or IV aircraft deicing/anti-icing fluid.
