  • Publication number: 20230227878
    Abstract: A process for the preparation of C4 to C24 alkyl polyglycosides by the use of an enzyme to react C4 to C24 alkyl glycoside with a glycosyl donor containing monosaccharide residues, wherein the C4 to C24 alkyl polyglycosides have a mole-average degree of polymerization (mean DP) of the glycoside chains of greater than 1.5 units. The C4 to C24 alkyl polyglycosides are particularly useful in personal care formulations.

  • Publication number: 20230227877
    Abstract: An enzymatic process for the preparation of C16 alkyl polyglycosides and/or C18 alkyl polyglycosides by reacting C16 alkyl glycoside and/or C18 alkyl glycoside with a glycosyl donor containing monosaccharide residues to form an alkyl polyglycoside intermediate which can be fractionated to form an alkyl polyglycoside product, wherein the mole-average degree of polymerization mean DP) of the glycoside chains is greater than or equal to 3.0 units and the molar concentration of alkyl triglycoside (DP3) is greater than alkyl monoglycoside (DPI). The C16/C18 alkyl polyglycoside product is particularly useful in health care formulations, especially in combination with and/or as a solubilizer for active pharmaceutical ingredients (APIs).

  • Patent number: 10857232
    Abstract: A surfactant composition comprises at least one alkylglycoside having the formula CnGm wherein C is an alkyl group that is unbranched or branched, saturated or unsaturated, derivatised or non-derivatised, and n is the number of carbon atoms in the alkyl group and is 14 to 24. G is a saccharide residue containing 5 to 6 carbon atoms, and m is a number from 4 to 20. The use and application of the surfactant composition in detergents, emulsifying agents, wetting agents, anti-aggregation and stabilising composition and dispersants comprising the same is also disclosed.

  • Patent number: 10037831
    Abstract: A nanowire device and a method of making a nanowire device are provided. The device includes a plurality of nanowires functionalized with different functionalizing compounds. The method includes functionalizing the nanowires with a functionalizing compound, dispersing the nanowires in a polar or semi-polar solvent, aligning the nanowires on a substrate such that longitudinal axes of the nanowires are oriented about perpendicular to a major surface of the substrate, and fixing the nanowires to the substrate.
