Ingredients explained
- Aqua (Water
- Primary solvent; requires preservatives at high concentration; adjust viscosity with thickeners
- Eau)
- Pure water, solvent and diluent; drinking water standard, no known allergens or irritation
- Cetearyl Alcohol
- Fatty alcohol emulsifier at 1-5%; non-ionic surfactant
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Brassicamidopropyl Dimethylamine
- Canola-derived cationic conditioner for hair/skin; water-soluble, watch anionic surfactant compatibility.
- Behentrimonium Chloride
- Cationic conditioner and preservative; used within restricted limits, high doses may irritate.
- Isopropyl Myristate
- Light synthetic ester, fast-drying and non-greasy; high comedogenic risk, limit in acne-prone skin
- Orbignya Speciosa Kernel Oil
- Not decoded yet
- Aspergillus Ferment
- Aspergillus ferment extract; skin conditioner rich in polysaccharides; potential allergen, buffer formulation
- Hydrolyzed Wheat Protein
- Hydrolyzed protein for hair and skin conditioning; potential allergen, use low levels in sensitive products
- Hippophae Rhamnoides Fruit Extract
- Sea buckthorn fruit extract for skin conditioning; stable at low levels, check phototoxicity at high doses.
- Arginine
- Arginine for moisturizing/conditioning; amino acid, high biocompatibility, often used in blends.
- Ximenia Americana Seed Oil
- Cupuacu seed oil for moisturizing and antioxidant effects; rich in unsaturated fats, needs stabilizers
- Hydrogenated Soybean Oil
- Hydrogenated soybean oil for emollience; slightly higher allergen risk than refined.
- Oryza Sativa Bran Extract
- Rice bran extract rich in vitamins; moisturizing and soothing, generally well-tolerated.
- Cocos Nucifera Oil
- Occlusive moisturizing oil at 1–10%; highly comedogenic, use with caution for oily skin.
- Linum Usitatissimum Seed Oil
- Flaxseed oil; high oleic, emollient; prone to oxidation.
- Helianthus Annuus Extract
- Sunflower extract; oleic/vit E rich; emollient, low irrit, good for dry skin, no pub comed data
- Rosmarinus Officinalis Extract
- Rosemary extract; antimicrobial; photo-toxic and allergen risks.
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Lactic Acid
- AHA pH adjuster at 0.5-5%; exfoliation/humectancy, mild at low conc., irritating at high, avoid conflict with alkaline preservatives.
- Tartaric Acid
- Small-molecule organic acid used as buffer and antioxidant; highly irritating at high levels, caution for sensitive skin
- Guar Hydroxypropyltrimonium Chloride
- Cationic guar derivative for antistatic, film-forming, viscosity control; common in hair/skin conditioning
- Hydroxypropylammonium Gluconate
- Cationic humectant and hair conditioner; anti-static, compatible with other cationic agents
- Polyquaternium-73
- Not decoded yet
- Hydroxypropylgluconamide
- Water-soluble humectant for hair and skin; supports internal hydration
- Isopropyl Alcohol
- Alcohol solvent at 1–10%; fast-evaporating, high levels may cause dryness/irritation
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Tetrasodium Glutamate Diacetate
- Gluconate diacetate tetrasodium chelator; replaces EDTA, improves stability against metals
- Sodium Benzoate
- Preservative booster, effective below pH 4.5; combinable with sorbates
- Potassium Sorbate
- Preservative effective below pH 6; combinable with sodium benzoate
- Benzyl Alcohol
- Mild preservative/solvent at 0.5-1.0%; EU allergen (labeling required), irritation risk if concentrated, avoid in infant/highly sensitive skin.
