Ingredients explained
- Aqua/Water/Eau
- Water as solvent/base; main ingredient, microbial control needed, paired with preservatives.
- Amodimethicone
- Amino silicone for hair conditioning/antistatic; cationic, conflicts with anionic surfactants
- Cetearyl Alcohol
- Fatty alcohol emulsifier at 1-5%; non-ionic surfactant
- Trideceth-5
- Not decoded yet
- Polyquaternium-37
- Not decoded yet
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Propylene Glycol Dicaprylate/Dicaprate
- Lightweight emollient, low viscosity, refreshes skin feel, high compatibility.
- Steareth-20
- Not decoded yet
- Parfum/Fragrance
- Blended fragrance for odor; contains 26 restricted allergens, use caution in sensitive/child/eye products, verify compliance.
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Phenyl Trimethicone
- Aromatic modified silicone for high gloss and occlusion; inert, non-volatile, may leave surface residue
- Cetyl Hydroxyethylcellulose
- Water-soluble cellulose derivative; viscosity booster and emulsion stabilizer; pH sensitive.
- Trideceth-10
- Not decoded yet
- Cetyl Alcohol
- Cetyl alcohol for emulsification/thickening; high concentration >10% may irritate.
- PPG-1 Trideceth-6
- Not decoded yet
- Prunus Amygdalus Dulcis Oil/Sweet Almond Oil
- Not decoded yet
- Biotin
- Vitamin B7 nutrient claimant; topical effect limited, use at 1-20 ppm.
- Polyquaternium-67
- Not decoded yet
- Arginine
- Arginine for moisturizing/conditioning; amino acid, high biocompatibility, often used in blends.
- Behentrimonium Methosulfate
- Cationic surfactant for conditioning and antistatic; be careful with anionic actives compatibility.
- Chlorhexidine Digluconate
- Antimicrobial agent often in oral care or antiseptics; residual odor noted; long-term use may cause resistance or sensitivity.
- Quaternium-33
- Not decoded yet
- Sodium Nitrate
- Milding agent mainly in oral care (mouthwash/toothpaste); rare in cosmetics.
- Benzyl Benzoate
- Chelating agent for stability; restricted substance, not permitted as single component or in mixtures at ≥0.1%.
- 2-Oleamido-1,3- Octadecanediol
- Not decoded yet
- Hydrolyzed Soy Protein
- Hydrolyzed soy protein for hydration and antistatic effect; soy is a common allergen requiring labeling, low comedogenicity.
- 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.
- Linalool
- Natural fragrance component at ≤0.05%; one of EU 26 allergens, caution for sensitive skin
- Silica
- Silica powder at 1–10%; absorbs oil, thickens, provides matte finish, for oil-control products
- Sodium Acetate
- Sodium acetate buffer for pH adjustment; sometimes acts as mild fragrance, common in lotions and washes
- Polysorbate 60
- Non-ionic emulsifier and solubilizer for O/W or W/O stability; may cause mild stinging on sensitive skin, typically 1-5%.
- Hydrolyzed Vegetable Protein Pg-Propyl Silanetriol
- Silane-modified polymer for smoothness and wet combing; pair with cationic conditioning agents
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
