Shin-Etsu Silicones Europe B.V. recently introduced SPD-WT1 (INCI: Titanium Dioxide (and) Butylene Glycol (and) Hydrated Silica (and) Polyglyceryl-3 DisiloxaneDimethicone (and) Hydrogen Dimethicone), a high concentration dispersion of hydrophobic treated ultrafine Titanium Dioxide (TiO 2) in water.

SPD-WT1 offers sensorial benefits and SPF properties in addition to its environmentally friendly profile by using water instead of organic or synthetic solvents − notably for sun care applications. The SESE technology provides high transparency and fluidity to formulations and as a low viscosity dispersion, it is also easy to mix into water.
Key features of the ingredient include:
- Aqueous dispersion of hydrophobic treated ultrafine TiO 2 that can be added to the water phase.
- High concentration TiO 2 dispersion making it easy to create high SPF products.
- Achieves both water resistance and washability with soap.
- Low viscosity and easy-to-use.
- ISO 16128 / Natural Origin Index (NOI): 76.5%.
According to SESE’s Head of Sales/Cosmetics, Dr. Martin Kropfgans, “if you have a water-based formulation, you might assume it is not water resistant − but we have data showing that it is. The data was the result of a test, where we applied each dispersion to synthetic leather and water resistance as well as washability were evaluated. As a conclusion, while being water resistant, it’s quite easily removeable if you use soap − whereas other water-based formulations were not water resistant.”
