Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Dimethicone
- Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin
- Alcohol Denat
- Denatured ethanol; solvent, penetration enhancer, and quick-dry agent; high % may compromise barrier in dry skin.
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Isocetyl Stearate
- Isocetyl stearate; emollient, low comedogenic risk
- Polyglyceryl-2 Stearate
- Polyglyceryl ester emulsifier; mild, non-ionic, suitable for O/W emulsions with good stability.
- Isononyl Isononanoate
- Light, low-viscosity ester emollient; excellent spreadability, good for gels and light lotions
- Pentylene Glycol
- Polyol humectant at 1-3%; low irritancy, suitable for sensitive skin
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Stearyl Heptanoate
- Lipophilic emollient and skin-conditioning agent; improves texture and reduces dryness; high levels may increase greasiness.
- PEG-8 Stearate
- Not decoded yet
- Mannose
- Monosaccharide humectant that binds glycosaminoglycans to enhance hydration; extremely low allergenicity
- Cetyl Alcohol
- Cetyl alcohol for emulsification/thickening; high concentration >10% may irritate.
- Hydroxypropyl Starch Phosphate
- Thickener and bulking agent for creams; 1-5%, avoid cationic systems
- Disodium Stearoyl Glutamate
- Amino acid-based mild cleanser with fine foam; water-soluble.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Stearyl Caprylate
- Light emollient ester; fast-spreading, non-tacky; improves texture and slip in most bases
- Sodium Polyacrylate
- Superabsorbent resin, <1%; gels with electrolytes, ionic strength control required.
- Stearic Acid
- Fatty acid emulsifier, white waxy solid; adds slip feel
- Palmitic Acid
- Palmitic acid for emulsification/emollient; solid fat, high melting point, occlusive.
- Limonene
- Natural fragrance solvent, EU allergen; poor photostability
- Vitreoscilla Ferment
- Vitroscilla ferment, natural humectant; microbe-derived, aseptic process, low allergen risk
- Glycine Soja Oil
- Soybean oil emollient; prone to oxidation, needs antioxidants; suitable for dry skin
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Stearyl Alcohol
- Stearic alcohol; fatty alcohol for emulsion thickening/structure, often blended with soaps, moderate comedogenicity.
- Myristyl Alcohol
- Long-chain fatty alcohol for emulsion stability and conditioning; slippery feel, low sensitization, common in creams.
- Myristic Acid
- Saturated fatty acid, saponification feedstock; insoluble alone, pairs with stearic acid.
- Benzyl Salicylate
- UV absorber/light stabilizer, restricted in EU; potential sensitizer, risk assessment needed.
- Linalool
- Natural fragrance component at ≤0.05%; one of EU 26 allergens, caution for sensitive skin
- Benzyl Alcohol
- Mild preservative/solvent at 0.5-1.0%; EU allergen (labeling required), irritation risk if concentrated, avoid in infant/highly sensitive skin.
- Alteromonas Ferment Extract
- Ferment filtrate with peptides/polysaccharides; skin conditioning, 1–3% typical; check preservative system.
- Hydroxypalmitoyl Sphinganine
- Not decoded yet
- Citral
- Citral; citrus fragrance component, listed EU allergen, high phototoxicity risk, strict concentration limits apply.
- Geraniol
- Geraniol for fragrance; EU 26 allergen, labeling required above 0.001%.
- Parfum
- Fragrance for scent; may contain allergens, caution for sensitive skin, full labeling required.
- Ci 42090
- Acid Blue 9 lake; for coloring and brow tints. Non-permanent hair dye, watch for lake precipitation and batch shade variance.
- Ci 19140
- Acid Yellow 23 lake; for coloring and hair dyeing. High water solubility and precipitation risk, pH control required.
- Ci 60730
- Synthetic colorant for yellow-green tones; use subject to regulatory limits
