Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Dimethicone
- Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Bis-PEG-12 Dimethicone
- Not decoded yet
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Polymethylsilsesquioxane
- Silicone polymer for emolliency, matte effect, and suspension; used in foundations or powder suspensions, typical usage 1-5%, smooth skin feel.
- Polysilicone-11
- Not decoded yet
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Polyglutamic Acid
- Natural-derived polypeptide for hydration and skin conditioning; often used for long-lasting moisture
- Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer
- Acrylate copolymer for film/thickening; water-soluble, compatible, monitor residual monomers.
- Isohexadecane
- Lightweight mineral-oil-derived emollient and solvent; low viscosity, non-comedogenic, improves texture
- Propanediol
- Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative
- Coco-Glucoside
- Mild non-ionic surfactant for cleansing and foaming; rich foam, low irritation, suitable for sensitive and children's products
- Sodium Benzoate
- Preservative booster, effective below pH 4.5; combinable with sorbates
- Hydroxyethylcellulose
- Water-soluble cellulose ether for thickening and suspension stabilization; sensitive to ions, electrolytes reduce viscosity, use at pH 7-8.
- Polysorbate 80
- Non-ionic emulsifier and solubilizer; watch for interaction with parabens
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
- Potassium Sorbate
- Preservative effective below pH 6; combinable with sodium benzoate
- Decyl Glucoside
- Mild alkyl glucoside, biodegradable; foam stabilizer, thickens with fatty alcohols, low allergenicity.
- Dimethylacrylamide/Acrylic Acid/Polystyrene Ethyl Methacrylate Copolymer
- Water-soluble film-forming polymer for thickening; potential trace monomer release, monitor sensitization for sensitive skin.
- Sorbitan Oleate
- Non-ionic emulsifier for oil-in-water systems; plant-derived, check oxidative stability
- Trisodium Ethylenediamine Disuccinate
- Mild chelator replacing EDTA; water-soluble, very low irritation, stabilizes metal ions
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
- Hexylene Glycol
- Polyol solvent and humectant with penetration enhancement; limit concentration to avoid irritation, no specific allergen tag
- Oryza Sativa Bran Extract
- Rice bran extract rich in vitamins; moisturizing and soothing, generally well-tolerated.
