Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Caffeine
- Active ingredient, 0.1–2%; promotes circulation, irritation risk at high concentration.
- Maltodextrin
- High-MW multifunctional excipient for thickening, binding, and emulsion stability; inert, non-penetrating conditioning.
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Propanediol
- Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative
- Epigallocatechin Gallatyl Glucoside
- Tea polyphenol analog; antioxidant & skin conditioning
- Gallyl Glucoside
- Gallate-derived glucoside as antioxidant and skin conditioner; use at low levels, avoid acidic matrix incompatibility.
- Hyaluronic Acid
- High-water-binding humectant at 0.1-1%; high-MW for surface film, low-MW for dermal potential, check cationic compatibility.
- Oxidized Glutathione
- Oxidized glutathione for skin conditioning; low stability requires light and oxygen protection
- Melanin
- Melanin as pigment or UV absorber; natural colorant, shade depends on purity, used in dark concealers.
- Glycine Soja Seed Extract
- Soybean extract for skin conditioning; low allergen risk, monitor batch protein variability.
- Pentylene Glycol
- Polyol humectant at 1-3%; low irritancy, suitable for sensitive skin
- Hydroxyethylcellulose
- Water-soluble cellulose ether for thickening and suspension stabilization; sensitive to ions, electrolytes reduce viscosity, use at pH 7-8.
- Polyacrylate Crosspolymer-6
- Water-soluble thickener; requires neutralizer, performs best at pH 5–7
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Lactic Acid
- AHA pH adjuster at 0.5-5%; exfoliation/humectancy, mild at low conc., irritating at high, avoid conflict with alkaline preservatives.
- Dehydroacetic Acid
- Broad-spectrum preservative for acidic and oil-based systems; has concentration limits, requires challenge testing.
- Trisodium Ethylenediamine Disuccinate
- Mild chelator replacing EDTA; water-soluble, very low irritation, stabilizes metal ions
- Propyl Gallate
- Oil-soluble antioxidant for oil stability; mild skin irritant.
- Dimethyl Isosorbide
- Dimethyl isosorbide as solvent and viscosity control; low toxicity, common use
- Benzyl Alcohol
- Mild preservative/solvent at 0.5-1.0%; EU allergen (labeling required), irritation risk if concentrated, avoid in infant/highly sensitive skin.
- 1,2-Hexanediol
- Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
