It also appears on labels as Ethylhexyl Salicylate.
Zinc Oxide
Bulking agent (adds volume)Colorant (adds colour)Light stabiliser (protects the formula from light)Oral care (CosIng functional class)Preservative (inhibits microbial growth)Skin protecting (CosIng functional class)UV absorber (protects the formula from light, not a sunscreen filter)UV filter (filters UV rays)A mineral UV filter that absorbs ultraviolet light, the core sun-protection job in this product. It also helps protect the skin surface and can add whiteness or opacity. On some labels it appears as CI 77947 when used for colour.
