Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Niacinamide
- Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity
- Cyclopentasiloxane
- Cyclopentasiloxane for emollient/solvent; volatile silicone, smooth feel, check VOC regulations.
- Dimethicone Crosspolymer
- Crosslinked silicone polymer providing silkiness and viscosity control; for hair and skin; inert but hard to biodegrade.
- Acrylates/Beheneth-25 Methacrylate Copolymer
- Acrylate copolymer thickener at 0.5–2%; incompatible with cationics, dilute first, PEG-modified
- Dimethicone
- Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin
- Silanetriol
- Basic silanetriol for hair anti-static and smoothness; must be complexed with polymers for stability
- Hyaluronic Acid
- High-water-binding humectant at 0.1-1%; high-MW for surface film, low-MW for dermal potential, check cationic compatibility.
- Triticum Vulgare Germ Oil
- Nutrient-rich emollient with Vit E; low irritancy but relevant for gluten-sensitive; prone to oxidation, needs antioxidants
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Methylisothiazolinone
- Strong preservative; high allergy risk, EU restricted for leave-on products, high formulation risk
- Zinc Pca
- Zinc salt for sebum control and antimicrobial; often paired with PCA sodium, high levels may cause sensitization
- Punica Granatum Fruit Extract
- Pomegranate extract for antioxidant conditioning; polyphenols may stain, need stabilizers.
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Hydroxyethyl Cellulose
- Water-soluble cellulose thickener; foaming risk, often paired with polyols.
- Tocopheryl Acetate
- Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light
- D-Panthenol
- Not decoded yet
- Perfume
- Perfume/Fragrance blend. Opaque composition, a leading cause of contact dermatitis. Must list specific EU 26 allergens if present. Patch test required.
- Glycyrrhiza Glabra Extract
- Glutinous licorice extract for brightening and calming; glycyrrhizic acid content varies
- Helianthus Annuus Seed Oil
- Sunflower seed oil for emollient/occlusive; high linoleic acid, low comedogenicity.
