Abstract: Amino-substituted hydroxybenzophenones (I) are used as photostable UV filters in cosmetic and pharmaceutical compositions for protecting human skin or hair against solar radiation, optionally in combination with other UV absorbers. Amino-substituted hydroxybenzophenones of formula (I) are used as photostable UV filters in cosmetic and pharmaceutical compositions for protecting human skin or hair against solar radiation, optionally in combination with other UV absorbers.
