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 stabiliser (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 acts as a light stabilizer, helping the formula hold up under sun exposure. On labels it also appears as Butyl Methoxydibenzoylmethane.

  • Homosalate

    Fragrance ingredient (scent)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 stabiliser (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 stabiliser (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)

    The base liquid that most of the other ingredients dissolve or spread into. It carries the formula and helps condition the skin surface.

  • Dimethicone

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

    A silicone that softens and smooths skin feel and forms a protective layer on the surface. It also cuts down foam during production, keeping the formula settled.

  • Alcohol Denat.

    Antifoaming (stops the formula foaming)Astringent (CosIng functional class)Fragrance ingredient (scent)otherPreservative (inhibits microbial growth)Solvent (dissolves other ingredients)Viscosity control (thickens or thins the formula)

    Alcohol Denat. is ethyl alcohol with additives that make it undrinkable, used as a solvent to dissolve ingredients and thin the formula. It also cuts foam, tightens skin as an astringent, and adjusts thickness. Denat. simply means it has been denatured.

    listed as “alcohol denat

  • Silica

    Abrasive (physically scrubs)Absorbent (takes up oil or water)Anticaking (keeps powder free-flowing)Bulking agent (adds volume)Opacifier (makes the formula less see-through)otherViscosity control (thickens or thins the formula)

    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.

  • Styrene/Acrylates Copolymer

    Film forming (leaves a thin coating)Opacifier (makes the formula less see-through)

    Styrene/Acrylates Copolymer forms a film and makes the product look opaque. In practice it leaves a thin layer on the skin and gives the formula a non-transparent appearance.

  • Butyloctyl Salicylate

    Emollient (softens and smooths skin)Hair conditioning (CosIng functional class)Skin conditioning (CosIng functional class)Solvent (dissolves other ingredients)

    A liquid that conditions skin and hair and acts as a solvent. It softens skin feel and helps dissolve and spread other ingredients in the mix.

  • PEG-30 Dipolyhydroxystearate

    Surfactant (cleanses or mixes oil and water)

    An emulsifier. It keeps the oil and water parts blended together so the formula stays even.

  • Polymethylsilsesquioxane

    Opacifier (makes the formula less see-through)

    This is an opacifier, meaning it makes the product look less see-through. It gives the formula a more solid, opaque appearance.

  • Tocopherol

    Antioxidant (slows the formula oxidising)Fragrance ingredient (scent)Occlusive (CosIng functional class)otherSkin conditioning (CosIng functional class)

    Tocopherol is a form of vitamin E used as an antioxidant, which helps keep the formula from going off. It also conditions skin and forms a thin surface layer that slows moisture loss. You may see it listed simply as vitamin E.

  • Phenoxyethanol

    This is a preservative that fights microbes. It helps keep the product from spoiling over time.

  • PEG-8 Laurate

    Surfactant (cleanses or mixes oil and water)

    A cleansing agent that also helps oil and water mix. It keeps the water and oil parts blended and helps lift away residue.
