Ingredients explained
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Niacinamide
- Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity
- Dipropylene Glycol
- Solvent for essential oils; better humectancy than PEG
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- 1,2-Hexanediol
- Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives
- Betaine
- Betaine for mild moisturizing/surfactant; low concentration 1-2% common, high may irritate.
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Hydrogenated Lecithin
- Emulsifier from lecithin; stable, used in powder emulsions
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Sorbitan Isostearate
- Non-ionic emulsifier (low HLB); typically used in blends, low comedogenicity, soft skin feel.
- Diphenyl Dimethicone
- Silicone for emollience and antistatic; used in hair and skin care, check compatibility with other silicones
- Triethylhexanoin
- Light ester for non-greasy feel and fragrance; low allergenicity, high levels can act as solvent
- Polyglyceryl-10 Oleate
- Mild emulsifier and emollient; 1-3%, suitable for sensitive skin formulations
- Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer
- High-molecular-weight thickener and emulsion stabilizer; requires electrolytes or acid adjustment near isoelectric point for optimal performance.
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
- Polysorbate 60
- Non-ionic emulsifier and solubilizer for O/W or W/O stability; may cause mild stinging on sensitive skin, typically 1-5%.
