Development Technology

Surface treatment is the technology that imparts various properties to powders by coating their surfaces with a chemical component. We offer a broad lineup of surface treated powders to meet various needs.

Key Benefits of Surface Treatment

ー Functional Enhancement ー
- Water repellency (oil affinity)
- Hydrophilicity (oil repellency)
- Surface-activity suppression (Phototolerance)
- Higher SPF performance
ー Improved Feel & Finish ー
- Smoothness
- Spreadability
- Gloss enhancement
- Color development
- Transparency
- Better adhesion
- Longer-lasting makeup
ー Easier Formulation Design ー
- Lower viscosity
- Reduced oil absorption
- Press-moldability
ー Improved Stability ー
- Long-term stability
