Ingredients explained
- Aqua/Water/Eau
- Water as solvent/base; main ingredient, microbial control needed, paired with preservatives.
- Cetearyl Alcohol
- Fatty alcohol emulsifier at 1-5%; non-ionic surfactant
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Maleic Acid
- Not decoded yet
- Ethanolamine
- pH adjuster; restricted in cosmetics, potential sensitizer and irritant.
- Behentrimonium Methosulfate
- Cationic surfactant for conditioning and antistatic; be careful with anionic actives compatibility.
- Parfum/Fragrance
- Blended fragrance for odor; contains 26 restricted allergens, use caution in sensitive/child/eye products, verify compliance.
- Stearamidopropyl Dimethylamine
- Cationic quaternary amine; antistatic/emulsifier; mild conditioning, affinity for keratin, no pub data
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Hydroxyethylcellulose
- Water-soluble cellulose ether for thickening and suspension stabilization; sensitive to ions, electrolytes reduce viscosity, use at pH 7-8.
- Ricinus Communis Seed Oil/Castor Seed Oil
- Castor oil; high viscosity, strong occlusion and hydration. Prone to oxidation; use antioxidants. Caution for castor allergy.
- Quaternium-91
- Not decoded yet
- Polyquaternium-37
- Not decoded yet
- Benzoic Acid
- Preservative and pH adjuster at 0.1–0.5%; low water solubility, best in acidic media, irritant at high levels.
- Paraffinum Liquidum/Mineral Oil/Huile Minerale
- Mineral oil; inert occlusive, low allergen risk; comedogenicity depends on purity grade.
- Cetrimonium Chloride
- Cationic surfactant/preservative for conditioning; irritating at high levels, restricted use
- Cetrimonium Methosulfate
- Not decoded yet
- PPG-1 Trideceth-6
- Not decoded yet
- Benzyl Benzoate
- Chelating agent for stability; restricted substance, not permitted as single component or in mixtures at ≥0.1%.
- Biotin
- Vitamin B7 nutrient claimant; topical effect limited, use at 1-20 ppm.
- Limonene
- Natural fragrance solvent, EU allergen; poor photostability
- Benzyl Alcohol
- Mild preservative/solvent at 0.5-1.0%; EU allergen (labeling required), irritation risk if concentrated, avoid in infant/highly sensitive skin.
- Acrylates Copolymer
- Acrylate synthetic polymer for film forming and antistatic; breathable film, control dosage carefully
- Linalool
- Natural fragrance component at ≤0.05%; one of EU 26 allergens, caution for sensitive skin
- 2-Oleamido-1,3-Octadecanediol
- Lipid-based emollient for barrier repair; lipophilic.
- Sorbitan Oleate
- Non-ionic emulsifier for oil-in-water systems; plant-derived, check oxidative stability
