A process comprising the steps of continuously adding a catalase enzyme to a process stream, wherein the process stream comprises an amine oxide surfactant and hydrogen peroxide; and mixing the process stream and catalase enzyme.

Catalase decomposition of hydrogen peroxide in surfactants

A process for preparing an ether-capped poly(oxyalkylated) alcohol surfactant which results in the absence of metallic catalyst component residues from the ether-capped poly(oxyalkylated) alcohol surfactant.

Process for preparing ether-capped poly(oxyalkylated) alcohol surfactants

N-alkyl polyhydroxy alkyl amines such as N-methyl glucamine having a Gardner Color of less than 1 are reacted with sources of fatty acyl groups such as methyl esters, anhydrides, and/or fatty acids that have greater than 98% transmittance at 460 nm in organic hydroxy solvents such as methanol to prepare N-alkyl polyhydroxy amine amides with good color. The N-alkyl polyhydroxyamines can be purified by crystallization, and/or subjected to reductive bleaching, to provide superior color. The reaction is preferably carried out at low temperature for short periods of time and with low catalyst levels to minimize formation of cyclic products. The resulting amide product can be further purified by treatment with anionic and cationic exchange resins to remove soap and amine impurities. The anionic ion exchange resin can be readily regenerated by acidifying it followed by washing with an organic solvent.
