Abstract: There is disclosed a phthalate-free, epoxidized plasticizer composition comprising a blend of: a) one or more fatty acid esters having less than 10% saturates; and b) one or more bio-based oil having an oxirane value of at least 5.0%. There is also disclosed a method of making a phthalate-free, epoxidized plasticizer composition comprising forming a blend of the fatty acid esters bio-based oils, wherein the one or more fatty acid esters and the bio-based oils are epoxidized either prior to forming the blend or in a single epoxidation step after the blend is formed. Plasticized composition containing the phthalate-free, epoxidized plasticizer composition, as well as articles made from such compositions are also disclosed.

Abstract: There is disclosed a low volatile, epoxidized plasticizer composition comprising a blend of a) one or more epoxidized fatty acid esters having at least 4% saturates; and b) one or more epoxidized bio-based oil, wherein the low volatile plasticizer is at least 80% free of organic volatiles. There is also disclosed a method of making a low volatile, epoxidized plasticizer composition as described herein, the method comprising hydrothermally treating the one or more epoxidized fatty acid esters and one or more epoxidized bio-based oil either before or after the blend is formed at conditions sufficient to remove at least 80% of trace organic volatiles while maintaining at least at least 4% saturates.

Abstract: Epoxidized fatty acid alkyl esters useful as plasticizers are obtained by reacting epoxidized fatty acid triglycerides with alcohol in the presence of an enzyme having transesterification activity.

Abstract: The efficacy of peroxy compounds such as hydrogen peroxide in bleaching compositions and the like may be enhanced by the presence of manganese carboxylates containing branched chain carboxylate and/or tartrate groups. The invention relates to the activation of peroxy compounds using particular types of manganese carboxylates so as to render such compounds more effective in bleaching stains from substrate surfaces and other such applications.
