  • Water-In-Silicone Oil Emulsion for Use as a Sunscreen Product
    Publication number: 20080226727
    Abstract: A water-in-silicone oil emulsion contains (i) in the range from 0.1 to 25% by weight of particles of metal oxide having a median particle volume diameter in dispersion in the range from 18 to 32 nm, (ii) 5 to 60% by weight of silicone oil, and (iii) greater than 20% by weight of water. The metal oxide particles are preferably incorporated into the emulsion in the form of an aqueous dispersion. The emulsion exhibits good skin feel, effective UV protection, stability and improved transparency.

  • Metal Oxide Dispersion
    Publication number: 20080057008
    Abstract: A dispersion contains particles of metal oxide having a median volume particle diameter in the range from 24 to 42 nm which are dispersed in a medium which includes a mixture of at least one polar material having an interfacial tension of less than 30 mNm?1 and at least one non-polar material having an interfacial tension of greater than 30 mNm?1. The dispersion can be fused in a sunscreen product that exhibits effective UV protection, transparency, and improved skin feel.
