Abstract: Encapsulated peroxide particles inhibit skin inflammation. A method of encapsulating a solid peroxide comprises dispersing solid peroxide particles (e.g., benzoyl peroxide) in an aqueous dispersion of fatty acid salt to form a peroxide/fatty acid salt dispersion, wherein the peroxide particles have a mean particle size (D50) of 10 μm or less; and subsequently encapsulating the solid peroxide particles by reacting the one or more monovalent fatty acid salts with one or more multivalent salts of calcium, magnesium, aluminum, silver, and/or zinc, thereby forming encapsulated peroxide particles.

Abstract: An organic peroxide formulation includes at least one organic peroxide and at least one cellulose compound. Embodiments of the organic peroxide formulations significant improvements in surface tackiness (often including but not limited to tack-free surfaces) when curing elastomers in the presence of oxygen. Embodiments of the present invention relate to organic peroxide formulations that can cure solid elastomers in the full or partial presence of oxygen using, for example, a hot air oven or tunnel, molten salt bath, or steam autoclave. Embodiments of the invention also relate to crosslinkable elastomer compositions, processes for curing the elastomers, and products made by such processes.

Abstract: Embodiments of organic peroxide formulations provide significant improvements in surface tackiness (often including tack-free surfaces) when curing elastomers in the presence of oxygen. The peroxide formulations may include, for example, one or more compounds selected from sulfur-containing compounds, organophosphite compounds, HALS (Hindered Amine Light Stabilizer) compounds, aliphatic allyl urethane compounds, and blends comprising nitroxides (e.g., 4-hydroxy-TEMPO) and quinones (e.g., mono-tert-butylhydroquinone).

Abstract: An organic peroxide composition is provided which is liquid or near liquid at 25° C. or a low melting solid and which includes at least one ethylenically unsaturated organic peroxide (i.e., an organic peroxide containing at least one carbon-carbon double bond) and at least one saturated organic peroxide. The organic peroxide composition may further include at least one mono- and/or poly-unsaturated compound and at least one free-radical trap. The organic peroxide can be blended into a polymer such as a powdered or granular polyethylene resin. This peroxide-containing polymer can be used in rotational molding, wherein the polymer is added to a mold which is heated in an oven with rotation, thereby melting the polymer and coating the inside of the mold.

Abstract: Formulations for producing modified bio-based polymers, especially bio-based polyesters like PLA and/or biodegradable polymers like PBAT, include at least one organic peroxide and at least one bio-based reactive additive. The at least one organic peroxide and/or the at least one bio-based reacted additive are capable of reacting with a bio-based polymer and/or biodegradable polymer to produce the modified bio-based and/or modified biodegradable polymer. The modified bio-based and/or modified biodegradable polymers have improved properties compared to non-modified bio-based and/or biodegradable polymers. The improved properties may related to processability, especially improved melt strength which results in easier processing while producing foamed polymers, thin films, such as blown film, cast film, tentered film and the like. The improved properties may be related to physical properties such as improved stiffness, toughness or tensile strength.
