SUNSIL-TIN50AS is an alkyl silane surface treated inorganic UV filter that provides broad spectrum protection from UV rays. As a white fine powder, SUNSIL-TIN50AS has a median particle size of 2.0-7.0 microns and is hydrophobic, making it well-suited for applications that require long-lasting UV protection without visible residue. SUNSIL-TIN50AS contains 39-43% titanium dioxide and has a pH range of 5-9, allowing it to be easily formulated into products without affecting the feel or appearance. Its high UV protection and stability make SUNSIL-TIN50AS an ideal active ingredient for formulations where extended sun exposure is expected.
