Ingredients explained
- Coconut Alkanes
- Coconut alkanes as solvents/emollients with medium volatility; check oxidation stability.
- Ascorbic Acid
- Vitamin C, potent antioxidant requiring acidic environment for stability; oxidizes and discolors easily, needs light and air protection, concentration 1-10%, pure L-ascorbic acid is more irritating.
- Coco-Caprylate/ Caprate
- Not decoded yet
- Silica
- Silica powder at 1–10%; absorbs oil, thickens, provides matte finish, for oil-control products
- Sodium Cocoyl Glutamate
- Amino acid surfactant, gentle cleansing; rich foam, may sting eyes, good compatibility.
- Mannitol
- Polyol humectant with binding/skin conditioning properties; high levels may cause osmotic irritation
- Citrus Aurantium Dulcis Flower Oil
- Essential oil for fragrance and astringency; contains allergens like linalool, limited by III/350
- Yeast Extract
- Yeast extract for skin care and protection; common, low allergy risk
- Copper Pca
- Copper PCA chelating agent and humectant; added in trace amounts (0.01-0.1%) to stabilize formulation and supply copper ions.
- Boswellia Carterii Oil
- Frankincense essential oil; penetrant; high-concentration allergen risk.
- Boswellia Serrata Extract
- Anti-inflammatory and soothing extract, 0.1–0.5%; contains boswellic acids, check compatibility with fragrances
- Glycogen
- Animal-derived polysaccharide humectant; 1–5% for skin feel and softness, verify source and purity, low allergy risk.
- Magnesium Ascorbyl Phosphate
- Water-soluble Vitamin C derivative for antioxidant and brightening; more stable than ascorbic acid
- Limonene
- Natural fragrance solvent, EU allergen; poor photostability
