Ingredients explained
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Diphenylsiloxy Phenyl Trimethicone
- Phenyl trimethicone for anti-foaming and slip; silicone-based, silky feel
- Pentaerythrityl Tetraethylhexanoate
- Esther emollient for a light, silky feel; heavy at high concentrations.
- 1,2-Hexanediol
- Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives
- Behenyl Alcohol
- Fat alcohol emulsifier/thickener at 1-3%; low comedogenic risk, check solubility in strong acid/base systems, add antioxidants.
- Dimethicone
- Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin
- Haberlea Rhodopensis Leaf Extract
- Haberlea leaf extract for skin conditioning; limited data, patch test recommended.
- Sodium Chondroitin Sulfate
- Humectant and antistatic agent for skin and hair; biocompatible and low irritation. Large molecular weight limits deep penetration.
- Adenosine Triphosphate
- ATP for skin conditioning, repair concept; stability in aqueous phase is a concern.
- Astragalus Membranaceus Root Extract
- Astragalus root extract for antioxidant and barrier-support conditioning
- Cordyceps Sinensis Extract
- Cordyceps sinensis extract, medicinal herb; antioxidant, humectant, skin protector, control concentration.
- Dioscorea Opposita Root Extract
- Yam root extract; polysaccharide-rich, traditional moisturizer and soother
- Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer
- High-molecular-weight thickener and emulsion stabilizer; requires electrolytes or acid adjustment near isoelectric point for optimal performance.
- Glyceryl Stearate
- Emulsifier at 1-3%; may require acid to prevent saponification
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
- Sodium Stearoyl Glutamate
- Mild amino-acid surfactant, poor solubility, pairs with fatty alcohols, fine foam.
- Squalane
- Emollient from plants or synthetic; light texture
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
- 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
- Peptide conditioning agent; control pH to prevent degradation, used in hair and skin care.
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Sorbitan Isostearate
- Non-ionic emulsifier (low HLB); typically used in blends, low comedogenicity, soft skin feel.
- PVP
- Polyvinylpyrrolidone for film forming and thickening; used in styling and adhesion, occasional eye irritation reported.
- Benzyl Alcohol
- Mild preservative/solvent at 0.5-1.0%; EU allergen (labeling required), irritation risk if concentrated, avoid in infant/highly sensitive skin.
- Dehydroacetic Acid
- Broad-spectrum preservative for acidic and oil-based systems; has concentration limits, requires challenge testing.
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Potassium Sorbate
- Preservative effective below pH 6; combinable with sodium benzoate
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Fragrance (Parfum
