Ingredients explained
- Gluconolactone
- Multifunctional agent for chelation and permeation; acidic, may irritate at high levels, buffer recommended.
- Lactobionic Acid
- Polyhydroxy acid for pH buffering; gentle, check stability at high levels
- Aqua/Water/Eau
- Water as solvent/base; main ingredient, microbial control needed, paired with preservatives.
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Gluconolactone
- Multifunctional agent for chelation and permeation; acidic, may irritate at high levels, buffer recommended.
- Isocetyl Stearate
- Isocetyl stearate; emollient, low comedogenic risk
- Hydrogenated Polydecene
- Hydrogenated polydecene, light mineral oil alternative, low comedogenic; silky, non-greasy.
- Arginine
- Arginine for moisturizing/conditioning; amino acid, high biocompatibility, often used in blends.
- Glyceryl Stearate
- Emulsifier at 1-3%; may require acid to prevent saponification
- Cetearyl Alcohol
- Fatty alcohol emulsifier at 1-5%; non-ionic surfactant
- PEG-100 Stearate
- Non-ionic emulsifier, requires ionics for stability; check PEG for formaldehyde.
- Lactobionic Acid
- Polyhydroxy acid for pH buffering; gentle, check stability at high levels
- Dimethicone
- Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin
- Magnesium Aluminum Silicate
- Oil-absorbing powder at 5–20%; for pressed/powder makeup, high levels may feel heavy
- Aesculus Hippocastanum Seed Extract
- Horse chestnut seed extract for skin care; soothing, used in circulation products
- Ascophyllum Nodosum Extract
- Ascophyllum nodosum extract, provides hydration and antioxidant protection; usually low concentration as natural functional additive.
- Tocopheryl Acetate
- Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light
- Palmitoyl Tripeptide-8
- Palmitoyl tripeptide-8 signaling peptide; 0.1–1%, aqueous stability watch
- Asparagopsis Armata Extract
- Not decoded yet
- Camellia Sinensis Leaf Extract
- Green tea extract for antioxidant/astringent; contains caffeine, possible irritation in sensitive skin.
- Epilobium Angustifolium Flower/Leaf/Stem Extract
- Botanical extract used as a skin conditioning agent
- Ammonium Glycyrrhizate
- Soothing anti-inflammatory and emulsifier; derived from licorice, minor allergen risk
- Caffeine
- Active ingredient, 0.1–2%; promotes circulation, irritation risk at high concentration.
- Bisabolol
- Soothing and anti-inflammatory agent, 0.01–0.1%; low irritation, good for sensitive skin.
- Zinc Gluconate
- Chelated zinc salt with antimicrobial and deodorizing effects; used in antiperspirants and oral care; has EU concentration limit.
- Sorbitol
- Polyol humectant with strong hygroscopy; tacky at high levels, pair with occlusives; also a solvent or adjuster.
- Mannitol
- Polyol humectant with binding/skin conditioning properties; high levels may cause osmotic irritation
- Ammonium Hydroxide
- Strong alkaline pH adjuster; use in low concentrations to neutralize acids, avoid direct mixing with strong acids.
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Dextran
- Polysaccharide for binding; water-soluble requires preservation.
- Disodium EDTA
- Chelating agent at 0.05–0.5%; sequesters metal ions for stability, boosts preservative efficacy
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
- Isopropyl Titanium Triisostearate
- Titanium isostearate complex for UVB absorption and emulsification aid; photostable, low irritancy, low comedogenicity.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Chlorphenesin
- Phenolic antimicrobial; strict EU limits apply, potential allergen, careful dosing required for leave-on products.
