Ingredients explained
- Benzoyl Peroxide
- Strong decolorizer/antibacterial for acne; medical use only, strictly prohibited in cosmetics.
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Magnesium Aluminum Silicate
- Oil-absorbing powder at 5–20%; for pressed/powder makeup, high levels may feel heavy
- Glyceryl Stearate
- Emulsifier at 1-3%; may require acid to prevent saponification
- PEG-100 Stearate
- Non-ionic emulsifier, requires ionics for stability; check PEG for formaldehyde.
- Sorbitol
- Polyol humectant with strong hygroscopy; tacky at high levels, pair with occlusives; also a solvent or adjuster.
- Dimethyl Isosorbide
- Dimethyl isosorbide as solvent and viscosity control; low toxicity, common use
- Disodium PEG-12 Dimethicone Sulfosuccinate
- Not decoded yet
- Tridecyl Stearate
- Tridecyl stearate emollient; lightweight, moderate comedogenic
- Neopentyl Glycol Dicaprylate/Dicaprate
- Light emollient ester for fast spreadability and a light feel.
- Paraffin
- Paraffin wax for occlusion/viscosity control; inert/safe, may affect breathability
- Cetyl Esters
- Blended cetyl esters used as emollient skin conditioning agents to provide softness and occlusion.
- Anthemis Nobilis Flower Extract
- Chamomile extract used for soothing; check for potential sensitizing allergens.
- Tridecyl Trimellitate
- Ester emollient for skin conditioning; lipophilic nature may increase comedogenicity for acne-prone skin.
- Trisodium Sulfosuccinate
- Trisodium sulfosuccinate, mild amphoteric surfactant; buffering and chelating, low foam and irritancy.
- PEG-12 Dimethicone
- Water-soluble silicone; provides slip and gloss, easily emulsified, common in hair and skin care.
- Sodium Sulfate
- Inorganic salt for viscosity; high concentrations cause osmotic dehydration.
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Sodium PCA
- Sodium PCA, NMF component, 1-10% humectant; salty/tacky at high levels.
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Imidazolidinyl Urea
- Formaldehyde releaser in preservative systems; monitor for formaldehyde and urea sensitivity issues.
- Methylparaben
- Preservative, narrow spectrum; often combined, check allergen risk and regulatory limits.
- Propylparaben
- Medium-chain preservative; restricted use, pH-sensitive efficacy.
- Fragrance
- Fragrance; concentration must control allergen risk, label specific components
