Ingredients explained
- Avobenzone
- Organic UV filter for UVB and part of UVA-I; poor photostability, used in synergy with other filters.
- Homosalate
- UVB sunscreen agent, often combined with others; stable but migratory; ensure regulatory compliance.
- Octisalate
- Octyloleate, ester solvent and emollient; used in sunscreens or diluting oils, light texture
- Octocrylene
- UV-B absorber and photostabilizer; has concentration limits, consider potential coral toxicity and allergenicity for specific groups.
- Coco-Caprylate/Caprate
- Lightweight mid-chain ester, quick spreading, suitable for oily skin, non-comedogenic.
- Dimethicone
- Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin
- Triheptanoin
- Triheptanin; 0.5–5% oil phase; non-greasy emollient, low comedogenic, oxidation-resistant, suits light formulas
- Silica
- Silica powder at 1–10%; absorbs oil, thickens, provides matte finish, for oil-control products
- Butyloctyl Salicylate
- Oil-soluble exfoliating emollient; avoid for aspirin-sensitive users and high-concentration leave-on products
- C9-12 Alkane
- C9-12 alkanes; solvent and emollient. Lightweight feel, verify source and refining history.
- Dilinoleic Acid/Butanediol Copolymer
- Polymer forming flexible films and plasticizing; low comedogenic risk
- Silica Silylate
- Silylate silica for anticaking, defoaming, emulsion stabilization, film-forming; improves powder flow/texture
- Tribehenin
- Waxy emollient providing slip; prone to oxidation, needs antioxidant system; good for dry skin.
- Sorbitol/Sebacic Acid Copolymer Behenate
- Polymer conditioning agent; controls viscosity, check compatibility with cationic systems
- C26-28 Alkyl Dimethicone
- Long-chain alkyl dimethicone for film-forming and skin conditioning; delivers lasting slip, non-comedogenic, common in facial care
- Dimethicone/Vinyl Dimethicone Crosspolymer
- Crosslinked silicone thickener at 0.5-2%; silky/matte feel, non-comedogenic, partial oil phase incompatibility, use co-solvent/pre-emulsification.
- Polyphenylsilsesquioxane
- Volatile silicone, film and antistatic; 5–15% typical, low irritation
- Dimethicone Crosspolymer
- Crosslinked silicone polymer providing silkiness and viscosity control; for hair and skin; inert but hard to biodegrade.
- Cellulose
- Plant-derived thickener at 0.1–1%; requires full hydration, poor cationic compatibility
- Ethylcellulose
- Water-insoluble film former and viscosity builder for suspensions; requires dispersion or premixing.
- Water/Aqua/Eau
- Primary aqueous solvent and carrier; no specific incompatibilities, focus on microbial stability.
- Castor Oil/Ipdi Copolymer
- Castor oil/IPDI copolymer; film former. **High risk**: IPDI is a restricted isocyanate. Strict regulatory review required.
- Tocopheryl Acetate
- Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light
- Bisabolol
- Soothing and anti-inflammatory agent, 0.01–0.1%; low irritation, good for sensitive skin.
- Butyrospermum Parkii Butter
- Shea butter for occlusive moisturizing; high melt point, rich texture, caution for oily skin.
