The SPD series is a UV-shielding dispersion that disperses fine titanium dioxide or zinc oxide particles in volatile silicone fluids.
Despite containing a high concentration of finely dispersed particles, it is a product with extremely low viscosity that is easy to handle.
It can be applied not only to sunscreens but also to makeup products such as makeup primers and liquid foundations.

(Not specified values)
The SPD series utilizes dispersants with high dispersing performance, enabling stable dispersion of high-concentration fine-particle powders. All products achieve low-viscosity dispersions.
Furthermore, they exhibit minimal tackiness from the dispersants, resulting in a smooth application feel.
Transmission Spectrum of SPD-T5, SPD-T7, SPD-Z5
A formulation containing 30% of each SPD series product was applied at a thickness of 6µm and measured.
SPD-T5
SPD-T5
- A dispersion of fine titanium oxide in cyclopentasiloxane.
- Thanks to a high-performance dispersant, this product is a high-concentration dispersion of titanium oxide (solid content: 40%) with extremely low viscosity and excellent dispersion stability.

SPD-T7
SPD-T7
- A dispersion of fine titanium oxide in cyclopentasiloxane.
- Using a high-performance dispersant, this product is a high-concentration dispersion of titanium oxide (solid content: 45%) with extremely low viscosity and excellent dispersion stability.
- It provides a smooth, non-sticky feel and high water resistance, enabling the creation of high SPF products.
SPD-Z5
SPD-Z5
- A dispersion of fine zinc oxide in cyclopentasiloxane.
- Thanks to a high-performance dispersant, this product is a high-concentration dispersion of zinc oxide with extremely low viscosity and excellent dispersion stability.
- It provides a smooth, non-sticky feel and high water resistance, enabling the production of high PA products.
SPD-T5L
SPD-T5L
- A volatile dimethicone dispersion of finely divided titanium oxide.
- Thanks to a high-performance dispersant, this product is a high-concentration dispersion of titanium oxide with extremely low viscosity and excellent dispersion stability.
- It provides a smooth, non-sticky feel and high water resistance, enabling the creation of high SPF products.
