Ingredients explained
- 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
- Sodium Chloride
- Salt for gel viscosity control; used as precipitant in soaps
- Cocamidopropyl Betaine
- Cocamidopropyl betaine; zwitterionic co-surfactant reducing irritation and boosting foam, common in mild cleansers.
- Fragrance
- Fragrance; concentration must control allergen risk, label specific components
- Polysorbate 20
- Non-ionic emulsifier and cleansing surfactant; contains PEG, control microbial load.
- PEG-80 Sorbitan Laurate
- Non-ionic solubilizer for fragrances and oils; high concentrations can compromise preservative efficacy.
- Tetrasodium EDTA
- Chelator removing metal ions to enhance antioxidant and preservative efficacy; very low usage, typically 0.05-0.1%, no direct skincare function.
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- DMDM Hydantoin
- Formaldehyde-releasing preservative (V/33 limit); monitor cumulative formaldehyde with fragrances.
- Yellow 5
- Synthetic dye for color; known allergen, may irritate sensitive skin.
- Red 40
- Common water-soluble synthetic dye; azo-based, potential sensitizer; check local prohibited colorant lists
- Blue 1
- Synthetic water-soluble dye for color; use within regulatory limits
