Ingredients explained
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Hexyldecanol
- Lightweight synthetic ester; provides non-greasy feel, fast-drying, low irritation
- Methylpropanediol
- Diol solvent and extraction carrier; enhances solubility of actives, low irritation profile.
- Cetearyl Alcohol
- Fatty alcohol emulsifier at 1-5%; non-ionic surfactant
- Glyceryl Stearate
- Emulsifier at 1-3%; may require acid to prevent saponification
- PEG-100 Stearate
- Non-ionic emulsifier, requires ionics for stability; check PEG for formaldehyde.
- Ceteareth-20
- Not decoded yet
- Cetearyl Glucoside
- Gentle non-ionic sugar-based emulsifier for low-irritation formulas; often co-blended
- Dimethicone
- Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin
- Carbomer
- Gelling thickener requiring neutralization; watch out for ion compatibility
- Tocopheryl Acetate
- Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light
- Allantoin
- Skin soother at 0.5-2%; promotes cell regeneration
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
- Hexylene Glycol
- Polyol solvent and humectant with penetration enhancement; limit concentration to avoid irritation, no specific allergen tag
- Methylisothiazolinone
- Strong preservative; high allergy risk, EU restricted for leave-on products, high formulation risk
