Ingredients explained
- Water/Aqua/Eau
- Primary aqueous solvent and carrier; no specific incompatibilities, focus on microbial stability.
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Dimethicone
- Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin
- Sorbitol
- Polyol humectant with strong hygroscopy; tacky at high levels, pair with occlusives; also a solvent or adjuster.
- Behenyl Alcohol
- Fat alcohol emulsifier/thickener at 1-3%; low comedogenic risk, check solubility in strong acid/base systems, add antioxidants.
- Behentrimonium Chloride
- Cationic conditioner and preservative; used within restricted limits, high doses may irritate.
- Stearyl Alcohol
- Stearic alcohol; fatty alcohol for emulsion thickening/structure, often blended with soaps, moderate comedogenicity.
- Cetyl Alcohol
- Cetyl alcohol for emulsification/thickening; high concentration >10% may irritate.
- Glyceryl Oleate
- Glyceride-based emulsifier and emolient with mild perfuming properties.
- Schinziophyton Rautanenii Kernel Oil

- Tetrapeptide-29 Argininamide
- Not decoded yet
- Tetrapeptide-28 Argininamide
- Not decoded yet
- Keratin
- Keratin for hair/skin conditioning; verify animal source and allergen status
- Hydrolyzed Keratin
- Hydrolyzed keratin; small peptides; barrier repair, humectant, no pub comed data
- Cocodimonium Hydroxypropyl Hydrolyzed Keratin
- Not decoded yet
- Aleurites Moluccana Seed Oil
- Kukui nut oil rich in oleic and linoleic acids; provides moisture and conditioning, no clear comedogenic data.
- Arginine Hcl
- Amphoteric amino acid salt, moisturizer and buffer; high levels may irritate sensitive skin.
- Hydrogenated Castor Oil/Sebacic Acid Copolymer
- Emollient and emulsifier copolymer derived from castor oil
- Argania Spinosa Kernel Oil
- Jojoba oil rich in unsaturated fats; good penetration, non-comedogenic, prone to oxidation requiring antioxidants
- Psidium Guajava Fruit Extract
- Botanical extract with astringent and skin conditioning properties
- Thioctic Acid
- Alpha-lipoic acid; potent antioxidant; poor water solubility, often used as ester derivatives
- Oenothera Biennis Oil
- Natural oil rich in GLA; supports barrier, prone to oxidation, needs antioxidants
- 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
- Aminopropyl Dimethicone
- Aminomodified silicone; emulsifies well, adds slip and anti-static at 1–5%
- Hydrolyzed Keratin Pg-Propyl Methylsilanediol
- Not decoded yet
- Allantoin
- Skin soother at 0.5-2%; promotes cell regeneration
- Glycolipids
- Cell membrane lipids mimicking skin barrier structure; used in repair formulations and biomimetic membranes

- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- PEG-6 Methyl Ether Dimethicone
- Not decoded yet
- PEG-90M
- Polyethylene glycol-based emulsifier and thickener at 0.1–0.5%; highly hydrophilic, may contain trace PEG impurities, caution for sensitive skin
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Hyaluronic Acid
- High-water-binding humectant at 0.1-1%; high-MW for surface film, low-MW for dermal potential, check cationic compatibility.
- Polyquaternium-55
- Not decoded yet
- Polysilicone-19
- Not decoded yet
- Dipropylene Glycol
- Solvent for essential oils; better humectancy than PEG
- Butyl Methoxydibenzoylmethane
- High-potency UVA filter (Parsol MXX); requires stabilizers and UVB blockers.
- Isopropyl Alcohol
- Alcohol solvent at 1–10%; fast-evaporating, high levels may cause dryness/irritation
- Sodium Ascorbyl Phosphate
- Vitamin C derivative antioxidant at 0.5–2%; light-sensitive, requires opaque packaging
