What each ingredient generally does

Each entry that matched a canonical ingredient, with the function recorded for it. These notes describe the role an ingredient plays in a formulation. They do not assess an ingredient.

  • Avobenzone

    Light stabilizer (protects the formula from light)UV absorber (protects the formula from light, not a sunscreen filter)UV filter (filters UV rays)

    An organic UV filter that absorbs ultraviolet light. It also adds scent to the product.

  • Octisalate

    Light stabilizer (protects the formula from light)UV absorber (protects the formula from light, not a sunscreen filter)UV filter (filters UV rays)

    An organic UV filter that absorbs ultraviolet light, and doubles as a light stabilizer to keep the formula steady in sun. It also appears on labels as Ethylhexyl Salicylate.

  • Octocrylene

    Light stabilizer (protects the formula from light)UV absorber (protects the formula from light, not a sunscreen filter)UV filter (filters UV rays)

    An organic UV filter that absorbs ultraviolet light. It also serves as a light stabilizer, helping keep other filters and the formula intact under sunlight.

  • Water

    Antiplaque (CosIng functional class)otherSkin conditioning (CosIng functional class)Solvent (dissolves other ingredients)

    Silica is a fine mineral powder that soaks up excess moisture and oil, and adjusts how thick the product feels. It keeps powders from clumping, adds bulk, and can make a formula look more opaque. Its chemical name is silicon dioxide.

  • Dimethicone

    Antifoaming (stops the formula foaming)Emollient (softens and smooths skin)Skin conditioning (CosIng functional class)Skin protecting (CosIng functional class)
