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.

  • Octinoxate

    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 when exposed to sunlight. You'll often see it listed as Ethylhexyl Methoxycinnamate.

  • 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.

  • Butylparaben

    A preservative that also carries a scent role. It helps keep the product from spoiling over time.

  • Cetearyl Alcohol

    Emollient (softens and smooths skin)Emulsion stabiliser (keeps oil and water mixed)Foam boosting (increases foam from other ingredients)Opacifier (makes the formula less see-through)Skin conditioning (CosIng functional class)Surfactant (cleanses or mixes oil and water)Viscosity control (thickens or thins the formula)

    A workhorse ingredient that softens skin feel, adjusts thickness, helps oil and water mix, and keeps the blend stable. In practice it thickens the product, keeps it from separating, gives a smooth feel, and can make the product look opaque. Despite its name, it behaves like a waxy solid, not a drying alcohol.

  • Citric Acid

    Buffering (holds the formula at a set acidity)Chelating (binds metal ions in the formula)Fragrance ingredient (scent)other

    Citric Acid is a mild acid used to fine-tune a formula's pH. It keeps the acidity steady (buffering), binds trace metals that would spoil the formula (chelating), and can add a scent note.

  • C13-14 Isoparaffin

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

    This is a light oily fluid that softens and smooths the skin's feel. It also works as a solvent, helping other ingredients dissolve and spread.

  • DEA-Cetyl Phosphate

    Surfactant (cleanses or mixes oil and water)

    A helper that lets oil and water mix into one smooth blend and also lifts away dirt and oil. In practice it keeps the formula from separating and gives it cleansing power.

  • Disodium EDTA

    Chelating (binds metal ions in the formula)otherViscosity control (thickens or thins the formula)

    An ingredient that binds trace metals that would otherwise spoil the formula, and helps adjust its thickness. This keeps the product stable over time.

  • Ethylhexyl Stearate

    Emollient (softens and smooths skin)Skin conditioning (CosIng functional class)

    An oil-like ingredient that softens and smooths the skin feel. It leaves a light, spreadable finish on the skin.

  • Ethylparaben

    A preservative that keeps the product from spoiling over time. It also adds a bit of fragrance. It belongs to the paraben group of preservatives.

  • Isobutylparaben

    Preservative (inhibits microbial growth)

    An antimicrobial that curbs the growth of microbes in the product. This helps keep the formula from spoiling.

  • Isopropyl Palmitate

    Binder (holds the formula together)Emollient (softens and smooths skin)Fragrance ingredient (scent)Skin conditioning (CosIng functional class)

    An emollient that softens and smooths skin feel while helping hold the formula together. It also can carry fragrance and lends a smooth, spreadable texture.

  • Laureth-7

    Surfactant (cleanses or mixes oil and water)
