Ingredients explained
- Aqua/Water
- Solvent, formulation base; requires preservation, pure water is microbially prone.
- Homosalate
- UVB sunscreen agent, often combined with others; stable but migratory; ensure regulatory compliance.
- Octocrylene
- UV-B absorber and photostabilizer; has concentration limits, consider potential coral toxicity and allergenicity for specific groups.
- Ethylhexyl Salicylate
- Ethylhexyl salicylate, UVB absorber; volatile, requires combination with UVA filters for broad spectrum.
- Butyl Methoxydibenzoylmethane
- High-potency UVA filter (Parsol MXX); requires stabilizers and UVB blockers.
- Alcohol Denat
- Denatured ethanol; solvent, penetration enhancer, and quick-dry agent; high % may compromise barrier in dry skin.
- Titanium Dioxide/Titanium Dioxide
- Titanium dioxide for UV protection, whitening, or pigment; non-nano forms are safe, nano forms debated.
- Ethylhexyl Triazone
- UVB absorber with good photostability; formulated with other filters, typical concentration 3-5%, check compatibility with other ingredients.
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Potassium Cetyl Phosphate
- Cetyl phosphate potassium, O/W emulsifier; pH-sensitive, often requires buffering.
- Talc
- Inorganic mineral powder for texture and oil absorption; must be asbestos-free; fineness affects skin feel and safety, avoid inhalation.
- Glyceryl Isostearate
- Glyceride emulsifier, oil-soluble; used in creams and ointments, 0.5–3%.
- Cyclohexasiloxane
- Volatile cyclic silicone evaporating without residue; ensure compliance with EU limits on cyclic polydimethylsiloxanes, use octamer
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Synthetic Wax
- Waxy solidifier for hardness and gloss; complex mixture, not a single molecule.
- Acrylates/C10-30 Alkyl Acrylate Crosspolymer
- Crosspolymer for thickening/film; needs neutralization to pH 7-8 to hydrate, check ion strength.
- Aluminum Hydroxide
- Aluminum hydroxide for emollient/thickening; opacifier, used in antiperspirants, particulate risk.
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
- Glyceryl Stearate
- Emulsifier at 1-3%; may require acid to prevent saponification
- Myristic Acid
- Saturated fatty acid, saponification feedstock; insoluble alone, pairs with stearic acid.
- Palmitic Acid
- Palmitic acid for emulsification/emollient; solid fat, high melting point, occlusive.
- PEG-100 Stearate
- Non-ionic emulsifier, requires ionics for stability; check PEG for formaldehyde.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Stearic Acid
- Fatty acid emulsifier, white waxy solid; adds slip feel
- Stearyl Alcohol
- Stearic alcohol; fatty alcohol for emulsion thickening/structure, often blended with soaps, moderate comedogenicity.
- Terephthalylidene Dicamphor Sulfonic Acid
- UV absorber and light stabilizer; EU regulated, check max levels and formulation stability
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Triethanolamine
- Triethanolamine for buffering; restricted, limit concentration to avoid high pH and irritation
