    摘要： A process for producing hydroxytyrosol (HTS) by enzymatic conversion of tyrosol to HTS is provided. The process includes a reaction mixture comprising tyrosol, a compound selected from the group consisting of erythorbic acid and erythorbate, and an oxidase with an amino acid sequence selected from the group consisting of SEQ ID NO: 2 and an amino acid sequence homologous with SEQ ID NO: 2. HTS is isolated from the reaction mixture.

    摘要： Aqueous dispersions and uses for the same. The aqueous dispersion includes a component (a) of one or more ethylene-vinyl ester copolymers and a component (b) of one or more protective colloids. The aqueous dispersion may optionally a component (c1) of one or more nonionic surfactants and/or a component (c2) of one or more ionic surfactants. Where a total amount of the component (b) is less than or equal to 2.2 pphm, preferably between 1-2.2 pphm, or more preferably 1.8 pphm. Additionally, where a total amount of the component (c1) and the component (c2) is less than 0.1 pphm, preferably less than or equal to 0.01 pphm.

    摘要： A siloxane composition, includes: (a) at least one organopolysiloxane containing two alkenyl groups bonded to silicon atoms at both ends of the chain per molecule, (b) at least one organopolysiloxane containing at least three alkenyl groups bonded to silicon atoms per molecule, (c) at least one organopolysiloxane containing two hydrogen atoms bonded to silicon atoms at both ends of the chain per molecule, and (d) at least one hydrosilylation catalyst, with the proviso that component (c) is in an amount of greater than or equal to 30 wt % based on the total weight of the composition, and component (e) at least one organopolysiloxane containing at least three hydrogen atoms bonded to silicon atoms per molecule is in an amount of less than or equal to 0.01 wt % based on the total weight of the composition.
