Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Cetyl Alcohol
- Cetyl alcohol for emulsification/thickening; high concentration >10% may irritate.
- Stearyl Alcohol
- Stearic alcohol; fatty alcohol for emulsion thickening/structure, often blended with soaps, moderate comedogenicity.
- 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.
- Polysorbate 60
- Non-ionic emulsifier and solubilizer for O/W or W/O stability; may cause mild stinging on sensitive skin, typically 1-5%.
- Mineral Oil
- Occlusive emollient preventing water loss; must use high-purity medical grade to avoid impurities.
- Isopropyl Myristate
- Light synthetic ester, fast-drying and non-greasy; high comedogenic risk, limit in acne-prone skin
- Titanium Dioxide
- Physical UV filter and colorant up to 25%; nano form requires attention
- Nicotinamide
- Not decoded yet
- Tocopheryl Acetate
- Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light
- Hamamelis Virginiana Flower Water
- Not decoded yet
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Aloe Barbadensis Extract
- Standardized aloe extract. Soothing and moisturizing; verify anthraquinone (allergen) removal. High purity usually well-tolerated.
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Parfum
- Fragrance for scent; may contain allergens, caution for sensitive skin, full labeling required.
