Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Isododecane
- Synthetic hydrocarbon solvent providing dry, silky skin feel; high volatility, non-comedogenic, common in sunscreens and foundations, usage 5-30%.
- Talc
- Inorganic mineral powder for texture and oil absorption; must be asbestos-free; fineness affects skin feel and safety, avoid inhalation.
- Coco-Caprylate
- Coconut/caprylate ester for light emollient finish; balance with humectants.
- Hydrogenated Tetradecenyl/Methylpentadecene
- Not decoded yet
- Lauryl PEG-8 Dimethicone
- Silicone surfactant for cleansing/conditioning; low allergen risk, avoid inhalation.
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Polypropylene
- Not decoded yet
- Trimethylsiloxysilicate
- Silicate powder, oil-absorbing emollient; insoluble, high levels feel powdery.
- Nylon-12
- Not decoded yet
- Hdi/Trimethylol Hexyllactone Crosspolymer
- Hydrophobic wax for anti-caking; improves slip in powders and cushions
- Disteardimonium Hectorite
- Inorganic ionic clay thickener at 0.25-1%; water/oil/solvent systems, rheology control, avoid strong acids, may affect active release.
- Sodium Chloride
- Salt for gel viscosity control; used as precipitant in soaps
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
- Sodium Dehydroacetate
- Sodium dehydroacetate, preservative <0.5%; restricted for eye, children, and lip use.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Methicone
- Volatile silicone offering slip and antistatic properties; inert at high purity, check cyclic isomer limits
- Tocopheryl Acetate
- Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
- Hexylene Glycol
- Polyol solvent and humectant with penetration enhancement; limit concentration to avoid irritation, no specific allergen tag
- Silica
- Silica powder at 1–10%; absorbs oil, thickens, provides matte finish, for oil-control products
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Hydrogen Dimethicone
- Hydrogenated dimethicone for film-forming and slip; low volatility, rich feel for dry skin
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Ci 77891
- Titanium dioxide inorganic pigment and UV filter; assess inhalation risk for nano-forms and EU restrictions
- Ci 77492
- Iron oxide red; stable inorganic pigment, non-toxic; ensure dispersion to prevent sedimentation.
- Ci 77491
- Iron oxides red; physical pigment. Coloring and photo-protective, stable and non-irritating.
- Ci 77499
- Inorganic colorant manganese dioxide used in cosmetics; restricted use component subject to regulatory limits.
