Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Sodium Laureth Sulfate
- Common anionic surfactant, strong foam but drying; check cationic compatibility, high eye irritation
- Laureth-2
- Not decoded yet
- Disodium Laureth Sulfosuccinate
- Mild anionic surfactant, boosts foam/cleaning; low irritancy, common in wash formulations
- Sodium Lauroyl Glutamate
- Amino acid surfactant, gentle and suitable for sensitive skin; moderate cleansing power.
- Sodium Chloride
- Salt for gel viscosity control; used as precipitant in soaps
- Caffeine
- Active ingredient, 0.1–2%; promotes circulation, irritation risk at high concentration.
- Panthenol
- Panthenol (vitamin B5) at 1–5%; moisturizing and reparative, supports barrier recovery
- Parfum
- Fragrance for scent; may contain allergens, caution for sensitive skin, full labeling required.
- PEG-120 Methyl Glucose Dioleate
- PEG-modified emulsifier; mild, low-foam. For O/W and anhydrous systems, check compatibility and viscosity.
- Hydrolyzed Wheat Protein
- Hydrolyzed protein for hair and skin conditioning; potential allergen, use low levels in sensitive products
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- Sodium Citrate
- Sodium citrate for buffering and chelating; adjust pH, careful with strong acid reactions.
- Menthol
- Cooling and soothing agent at 0.5–2%; high levels may cause sensitivity or irritation, use caution around eyes and mucous membranes
- PEG-40 Hydrogenated Castor Oil
- Solubilizer and emulsifier for oil-soluble ingredients; high concentrations may cause contact dermatitis in sensitive skin.
- Potassium Sorbate
- Preservative effective below pH 6; combinable with sodium benzoate
- Polyquaternium-7
- Not decoded yet
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
- Sodium Benzoate
- Preservative booster, effective below pH 4.5; combinable with sorbates
- Zinc Pca
- Zinc salt for sebum control and antimicrobial; often paired with PCA sodium, high levels may cause sensitization
- Niacinamide
- Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity
- Limonene
- Natural fragrance solvent, EU allergen; poor photostability
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- 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.
- Propylparaben
- Medium-chain preservative; restricted use, pH-sensitive efficacy.
- Ci 42090
- Acid Blue 9 lake; for coloring and brow tints. Non-permanent hair dye, watch for lake precipitation and batch shade variance.
- Ci 60730
- Synthetic colorant for yellow-green tones; use subject to regulatory limits
