Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- C12-15 Alkyl Benzoate
- C12-15 alkyl benzoate; emollient, emulsifier, and antistatic; aids stability and smoothness, moderate low comedogenicity.
- Diethylamino Hydroxybenzoyl Hexyl Benzoate
- Novel UVB absorber at 0.2-1.5%; narrow band, requires combination, high photostability, verify regional limits, low irritation.
- Butyl Methoxydibenzoylmethane
- High-potency UVA filter (Parsol MXX); requires stabilizers and UVB blockers.
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Dicaprylyl Ether
- Lightweight diester solvent and emollient, non-greasy feel; common oil phase carrier; low irritation.
- Ethylhexyl Salicylate
- Ethylhexyl salicylate, UVB absorber; volatile, requires combination with UVA filters for broad spectrum.
- Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine
- UV-B absorber, photostable; high purity and low bioaccumulation, check for impurities.
- Hexylene Glycol
- Polyol solvent and humectant with penetration enhancement; limit concentration to avoid irritation, no specific allergen tag
- Diethylhexyl Butamido Triazone
- Tinosorb S UV filter for UVA; low skin irritancy, photostable, use in sun care formulations.
- Ethylhexyl Triazone
- UVB absorber with good photostability; formulated with other filters, typical concentration 3-5%, check compatibility with other ingredients.
- Sodium Stearoyl Glutamate
- Mild amino-acid surfactant, poor solubility, pairs with fatty alcohols, fine foam.
- Phenylbenzimidazole Sulfonic Acid
- UV absorber and light stabilizer; compliant use required, common in sunscreens
- Microcrystalline Cellulose
- Cellulose derivative for anti-caking, oil absorption, and physical sunscreen carrier; water-insoluble, affects texture at high levels.
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Decylene Glycol
- Multi-functional thickener and preservative booster, 0.1–0.5%; low viscosity, good compatibility
- Cetearyl Alcohol
- Fatty alcohol emulsifier at 1-5%; non-ionic surfactant
- Glyceryl Stearate
- Emulsifier at 1-3%; may require acid to prevent saponification
- Tocopheryl Acetate
- Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light
- Cellulose Gum
- Cellulose gum, water-soluble thickener/stabilizer; may destabilize with cationics, hydrate first.
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
