Ingredients explained
- Pyrithione Zinc
- Anti-malassezia agent for dandruff control; 0.1–1% (shampoo) or 0.5–2% (body), slightly higher irritation
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Sodium Laureth Sulfate
- Common anionic surfactant, strong foam but drying; check cationic compatibility, high eye irritation
- Cocamidopropyl Betaine
- Cocamidopropyl betaine; zwitterionic co-surfactant reducing irritation and boosting foam, common in mild cleansers.
- Ammonium Lauryl Sulfate
- Strong anionic surfactant; high foaming and stripping power. Can be irritating to eyes and damaged skin
- Sodium Methyl Cocoyl Taurate
- Amino acid based mild surfactant, soft lather; cleaning power increases with salt but may dry out.
- Divinyldimethicone/Dimethicone Copolymer
- Silicone copolymer for slip and film; occlusive with smooth texture
- C12-13 Pareth-3
- Not decoded yet
- C12-13 Pareth-23
- Not decoded yet
- Guar Hydroxypropyltrimonium Chloride
- Cationic guar derivative for antistatic, film-forming, viscosity control; common in hair/skin conditioning
- Hydrolyzed Wheat Protein Pg-Propyl Silanetriol
- Hydrolyzed wheat protein and silane derivative; provides conditioning, assess wheat allergy
- Tocopheryl Acetate
- Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light
- Amodimethicone
- Amino silicone for hair conditioning/antistatic; cationic, conflicts with anionic surfactants
- Cetearyl Alcohol
- Fatty alcohol emulsifier at 1-5%; non-ionic surfactant
- Ceteareth-20
- Not decoded yet
- Castor Isostearate Succinate
- Castor derivative emulsifier giving slip; biodegradable, comedogenicity not public.
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Sodium Chloride
- Salt for gel viscosity control; used as precipitant in soaps
- Acrylates Copolymer
- Acrylate synthetic polymer for film forming and antistatic; breathable film, control dosage carefully
- DMDM Hydantoin
- Formaldehyde-releasing preservative (V/33 limit); monitor cumulative formaldehyde with fragrances.
- Blue 1
- Synthetic water-soluble dye for color; use within regulatory limits
- Fragrance
- Fragrance; concentration must control allergen risk, label specific components
