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.

  • Oxybenzone

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

    Oxybenzone is an organic UV filter that absorbs ultraviolet light. It also works as a light stabilizer, helping the formula hold up under sun exposure. On labels it often appears as Benzophenone-3.

  • 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.

  • 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”

  • 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.

  • Cyclopentasiloxane

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

    This is a lightweight silicone used to condition skin and hair and to soften and smooth skin feel. It also acts as a solvent, helping the product spread and dissolve other ingredients.

  • Acrylates/Dimethicone Copolymer

    Anticaking (keeps powder free-flowing)Binder (holds the formula together)Film forming (leaves a thin coating)Skin conditioning (CosIng functional class)

    A silicone-acrylic blend that forms a thin film and conditions skin. It helps the product spread into an even layer, keeps powdery ingredients from clumping, holds the mix together, and softens skin feel.

  • Phenoxyethanol

    Preservative (inhibits microbial growth)

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

  • Propylene Glycol

    Fragrance ingredient (scent)Humectant (holds moisture)Skin conditioning (CosIng functional class)Solvent (dissolves other ingredients)Viscosity control (thickens or thins the formula)

    A multi-tasker that draws in and holds moisture, dissolves other ingredients as a solvent, and adjusts thickness. It also plays a role in fragrance and general skin conditioning. In practice it helps keep the product from drying out and keeps the texture consistent.

  • Caprylyl Glycol

    Deodorant (masks or reduces odour)Emollient (softens and smooths skin)Hair conditioning (CosIng functional class)Preservative (inhibits microbial growth)Skin conditioning (CosIng functional class)

    A multi-tasker that conditions skin and hair and acts as a deodorant. As an emollient it softens and smooths, leaving skin feeling conditioned.

    listed as “capryly glycol”

  • Sodium Polyacrylate

    Absorbent (takes up oil or water)Binder (holds the formula together)Emollient (softens and smooths skin)Emulsion stabiliser (keeps oil and water mixed)Film forming (leaves a thin coating)Hair fixing (holds hair in place)Skin conditioning (CosIng functional class)Viscosity control (thickens or thins the formula)

    Sodium Polyacrylate is a multi-tasking ingredient that adjusts a product's thickness, helps hold ingredients together, and stabilises oil-and-water blends. It forms a thin film on the surface, softens and conditions skin, and can absorb liquid. In hair products it also helps hold a style in place.
