  • Publication number: 20150216783
    Abstract: A method of preparing oxidised cellulose and intermediate oxidised cellulose, and compositions or dispersions comprising said oxidised cellulose are disclosed. Cellulose particles with a median volume particle diameter (D(v,0.5)s) in the range from 30 ?m to 70 ?m are reacted in the presence of a nitroxyl radical catalyst, halide co-catalyst, and oxidant, to produce intermediate oxidised cellulose particles. The intermediate oxidised cellulose particles are neutralised, and shear pressure applied to produce oxidised cellulose particles having a median volume particle diameter value (D(v,0.5)p) of less than D(v,0.5)s, a ratio of D(v,0.5)s to D(v,0.5)p from 1.1 to 5.0:1, and an oxidation value in the range from 15% to 30%. The oxidised particles may be formed in to dispersions, with the dispersions particularly used to provide desired skin feel in personal care compositions.

  • Patent number: 9044622
    Abstract: Inverse emulsions made by inverse emulsion polymerization have a disperse aqueous phase comprising a solution or dispersion of at least one water soluble polymer, particularly a polymer that forms a viscous solution or dispersion in water, and a continuous oil phase which is or includes an ester oil including an alkoxylated alcohol group. The inclusion of ester oil including an alkoxylated alcohol group provides these oils in emulsions, particularly personal care emulsions made by inversion of the inverse emulsions on dilution with water.
