Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Coco-Caprylate/Caprate
- Lightweight mid-chain ester, quick spreading, suitable for oily skin, non-comedogenic.
- Dicaprylyl Carbonate
- Light emollient solvent at 5–15%; mineral oil-free, refreshing feel, low sensitization.
- Dicaprylyl Ether
- Lightweight diester solvent and emollient, non-greasy feel; common oil phase carrier; low irritation.
- Octocrylene
- UV-B absorber and photostabilizer; has concentration limits, consider potential coral toxicity and allergenicity for specific groups.
- Propanediol
- Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative
- Butyl Methoxydibenzoylmethane
- High-potency UVA filter (Parsol MXX); requires stabilizers and UVB blockers.
- Ethylhexyl Salicylate
- Ethylhexyl salicylate, UVB absorber; volatile, requires combination with UVA filters for broad spectrum.
- Diethylamino Hydroxybenzoyl Hexyl Benzoate
- Novel UVB absorber at 0.2-1.5%; narrow band, requires combination, high photostability, verify regional limits, low irritation.
- Ethylhexyl Triazone
- UVB absorber with good photostability; formulated with other filters, typical concentration 3-5%, check compatibility with other ingredients.
- Phenylbenzimidazole Sulfonic Acid
- UV absorber and light stabilizer; compliant use required, common in sunscreens
- Trimethylpentanediol/Adipic Acid/Glycerin Crosspolymer
- Water-soluble polymer solubility/skin conditioning 0.1-1%; improves spread
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Tromethamine
- pH adjuster, alkaline; precise dosing required
- Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine
- UV-B absorber, photostable; high purity and low bioaccumulation, check for impurities.
- Sodium Chloride
- Salt for gel viscosity control; used as precipitant in soaps
- Phenylpropanol
- Phenylpropanol for fragrance and solvent; allergen risk, requires assessment
- Parfum
- Fragrance for scent; may contain allergens, caution for sensitive skin, full labeling required.
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
- 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
- Chlorella Vulgaris Extract
- Algae extract for skin conditioning and antioxidant; typically 1-5%, monitor stability
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Linalool
- Natural fragrance component at ≤0.05%; one of EU 26 allergens, caution for sensitive skin
- Alpha-Isomethyl Ionone
- Vanilla-like fragrance ingredient; one of EU 26 allergens, caution advised for sensitive skin.
- Ci 42090
- Acid Blue 9 lake; for coloring and brow tints. Non-permanent hair dye, watch for lake precipitation and batch shade variance.
