Ingredients explained
- Fermented Cane Sugar Extract
- Not decoded yet
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- BG
- Butylene glycol; humectant and solvent. Low irritancy, common in water-in-oil and oil-in-water formulas.
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Ethanol
- Fast-evaporating solvent and enhancer; drying feel, high concentrations require irritation assessment.
- Glycereth-26
- Glycereth-26, humectant/viscosity modifier at 1–5%; non-ionic water-soluble, boosts stability and feel.
- Artichoke Leaf Extract
- Not decoded yet
- Hyaluronic Acid
- High-water-binding humectant at 0.1-1%; high-MW for surface film, low-MW for dermal potential, check cationic compatibility.
- Rice Bran
- Rice bran; exfoliant or lipid source, grainy, process for texture
- Black Rice Germ Oil
- Not decoded yet
- Safflower Oil
- Not decoded yet
- Perilla Seed Oil
- Not decoded yet
- Ceramides
- Not decoded yet
- Camellia Oil
- Camellia oil as emollient carrier; oleic-rich profile improves feel; assess oxidative stability and pair with antioxidants.
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Witch Hazel Extract
- Witch hazel extract; natural astringent for oil control, 1-5% use, high doses may dry skin.
- Magnesium Ascorbyl Phosphate
- Water-soluble Vitamin C derivative for antioxidant and brightening; more stable than ascorbic acid
- EDTA 2Na
- Chelating agent that enhances preservative efficacy and stabilizes formulations; usage must be controlled to prevent metal ion interference.
- Vinyl Dimethicone/Methicone Silsesquioxane Crosspolymer
- Rheology-modifying silicone polymer for suspension and feel; requires silicone-compatible system
- Isohexadecane
- Lightweight mineral-oil-derived emollient and solvent; low viscosity, non-comedogenic, improves texture
- Oleic Acid
- Oleic acid for emolliency/emulsification; high levels may increase skin penetration
- Sorbitan Oleate
- Non-ionic emulsifier for oil-in-water systems; plant-derived, check oxidative stability
- Carbomer
- Gelling thickener requiring neutralization; watch out for ion compatibility
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Methylparaben
- Preservative, narrow spectrum; often combined, check allergen risk and regulatory limits.
- Perfume
- Perfume/Fragrance blend. Opaque composition, a leading cause of contact dermatitis. Must list specific EU 26 allergens if present. Patch test required.
