- UV Titan M 212 (Kemira) was used as the hydrophilically coated titanium dioxide
- UV Titan M 262 (Kemira) as the hydrophobically coated titanium dioxide.
- a dispersion was accessible which contained 40% by weight of titanium dioxide in 60% by weight of polyethylene glycol monomethyl ether (7 EO).
- the dispersion had a better particle size distribution than commercially available dispersions.
- the particle size distribution was determined by laser light scattering (Fraunhofer diffraction). .100% of the particles had a diameter of less than 1 ⁇ m, the mean particle diameter being 350 nm.
- Both dispersions could be dispersed in water in any ratio, the mean particle diameter remaining the same.
- both dispersions could be introduced in any ratio in C 12 -C 5 alcohol benzoate, the average particle size also remaining the same.
- the dispersion could be fully integrated into C 12 - C 15 alcohol benzoate.
