Ingredients explained
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Bis-Aminopropyl Diglycol Dimaleate
- Bis-aminopropyl diglycol dimaleate, hair conditioner; cationic conditioner for post-perm care, control concentration.
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Cetearyl Alcohol
- Fatty alcohol emulsifier at 1-5%; non-ionic surfactant
- Behentrimonium Methosulfate
- Cationic surfactant for conditioning and antistatic; be careful with anionic actives compatibility.
- Cetyl Alcohol
- Cetyl alcohol for emulsification/thickening; high concentration >10% may irritate.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Hydroxyethyl Ethylcellulose
- Cellulose derivative for thickening and film-forming; use at low levels to avoid tackiness.
- Stearamidopropyl Dimethylamine
- Cationic quaternary amine; antistatic/emulsifier; mild conditioning, affinity for keratin, no pub data
- Quaternium-91
- Not decoded yet
- Sodium Benzoate
- Preservative booster, effective below pH 4.5; combinable with sorbates
- Cetrimonium Methosulfate
- Not decoded yet
- Cetrimonium Chloride
- Cationic surfactant/preservative for conditioning; irritating at high levels, restricted use
- Fragrance
- Fragrance; concentration must control allergen risk, label specific components
- Polyquaternium-37
- Not decoded yet
- Tetrasodium EDTA
- Chelator removing metal ions to enhance antioxidant and preservative efficacy; very low usage, typically 0.05-0.1%, no direct skincare function.
- Butylphenyl Methylpropional
- Synthetic fragrance with floral notes; EU regulations limit usage, strict monitoring required.
- Etidronic Acid
- Etidronic acid chelator, restriction III/53 (<0.01%); binds metal ions to prevent oxidative discoloration.
- 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.
- Phytantriol
- Botanical-derived humectant from phytane derivatives; enhances skin water retention
- Prunus Amygdalus Dulcis Oil
- Sweet almond oil, light emollient; suitable for sensitive skin, caution for nut allergies.
- Tocopheryl Acetate
- Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light
- Aloe Barbadensis Leaf Juice
- Natural humectant and soother with high water activity; requires preservative system, generally well-tolerated
- Panthenol
- Panthenol (vitamin B5) at 1–5%; moisturizing and reparative, supports barrier recovery
- Simmondsia Chinensis Seed Oil
- Common in dry/damaged hair; superior penetration vs mineral oils, low comedogenic risk, poor oxidative stability.
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- Potassium Sorbate
- Preservative effective below pH 6; combinable with sodium benzoate
