  • Particulate metal oxide particles comprising a metal oxide core and a coating layer comprising an inorganic material, a silane coupling agent and/or a hydrophobizing agent
    Patent number: 10869826
    Abstract: A particulate metal oxide has a metal oxide core and a coating layer containing an inorganic material and (i) a quaternary silane coupling agent, and/or (ii) a silane coupling agent and a hydrophobizing agent. Preferred materials are titanium dioxide core particles, an amino organosilane coupling agent and a fatty acid hydrophobizing agent. The particulate metal oxide is suitable for use in forming a dispersion, and the particles and dispersion can be used in an end-use sunscreen composition which is transparent, exhibits effective UV absorption properties, reduced photoactivity, and/or improved skin feel.
    Type: Grant

  • Particulate titanium dioxide
    Patent number: 9682869
    Abstract: A particulate titanium dioxide has a median volume particle diameter of greater than 70 nm. The titanium dioxide can be produced by calcining precursor particles. The titanium dioxide has enhanced UVA efficacy. The particulate titanium dioxide can be used to form dispersions. The particulate titanium dioxide or dispersions can be used to produce sunscreen products having a UV protection which is at least one third of the label SPF value.
