- Aqua
- Solvent, main base; microbial control is critical
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Methylpropanediol
- Diol solvent and extraction carrier; enhances solubility of actives, low irritation profile.
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- PEG-40 Hydrogenated Castor Oil
- Solubilizer and emulsifier for oil-soluble ingredients; high concentrations may cause contact dermatitis in sensitive skin.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Niacinamide
- Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity
- Inositol
- Humectant at 0.5–2%; gentle moisturizing, suitable for sensitive skin
- Imidazolidinyl Urea
- Formaldehyde releaser in preservative systems; monitor for formaldehyde and urea sensitivity issues.
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Allantoin
- Skin soother at 0.5-2%; promotes cell regeneration
- Panthenol
- Panthenol (vitamin B5) at 1–5%; moisturizing and reparative, supports barrier recovery
- Menthyl Safflowerseedate
- Not decoded yet
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
- Sodium Lactate
- Sodium lactate for moisturizing and exfoliation; pH buffering agent
- Triethanolamine
- Triethanolamine for buffering; restricted, limit concentration to avoid high pH and irritation
- Oryza Sativa Bran
- Rice bran; physical exfoliant, adjust particle roughness to avoid barrier damage.
- Glycyrrhiza Glabra Root Extract
- Liquorice root extract for soothing and brightening; batch variability, watch polyphenol interactions
- Tocopheryl Acetate
- Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light
