AakoSun BTZ is a UV B absorber. Very small concentrations are required to achieve a high SPF value. AakoSun BTZ is very soluble in cosmetic emollients and can readily be incorporated in the oily phase of emulsions. Because of its hydrophobic nature it is particularly suitable for water-repellent and water-resistant formulations. AakoSun BTZ can be used in combination with other organic and inorganic UV filters.
