Ingredients explained
- Water
- Primary solvent and base; requires preservative system to prevent microbial growth
- Inulin
- Plant fiber/prebiotic for moisturizing; fully dissolve to avoid crystallization
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Isoamyl Laurate
- Lightweight ester emollient; fast-drying, non-greasy feel, suitable for oily skin or summer formulations
- Propanediol
- Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative
- Squalane
- Emollient from plants or synthetic; light texture
- Cetearyl Olivate
- Natural emulsifier pairing with glucosides; skin-like feel, biodegradable, prone to oxidation requiring light protection
- Sorbitan Olivate
- O/W emulsifier, HLB ~15, requires ionic co-surfactant, potential sensitizer.
- Avena Sativa Kernel Oil
- Oat kernel oil for skin conditioning; moisturizing, sensitive skin friendly
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Yogurt Powder
- Not decoded yet
- Sodium Caproyl Prolinate
- Not decoded yet
- Citronellyl Methylcrotonate
- Used for floral fragrance notes; listed as one of the 26 EU allergens, must be declared in labeling.
- Isoamyl Cocoate
- Light ester with high comedogenic risk; prone to oxidation, requires antioxidants
- Carbomer
- Gelling thickener requiring neutralization; watch out for ion compatibility
- Benzyl Alcohol
- Mild preservative/solvent at 0.5-1.0%; EU allergen (labeling required), irritation risk if concentrated, avoid in infant/highly sensitive skin.
- Camellia Sinensis Leaf Extract
- Green tea extract for antioxidant/astringent; contains caffeine, possible irritation in sensitive skin.
- Lactobacillus Ferment Lysate
- Lactobacillus ferment lysate for skin conditioning; provides soothing and hydration, low sensitization risk if sterile.
- Punica Granatum Extract
- Pomegranate extract containing polyphenols; offers antioxidant and skin-protecting properties, often used in brightening formulas.
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Sodium Hydroxide
- Strong base neutralizer for pH adjustment; handle with extreme care
- Ethylhexylglycerin
- Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel
- Sodium Stearoyl Glutamate
- Mild amino-acid surfactant, poor solubility, pairs with fatty alcohols, fine foam.
- Diglucosyl Gallic Acid
- Diglucosyl gallic acid from tea, hair antioxidant; water-soluble, gentle on scalp
- Lactobacillus Ferment
- Probiotic ferment filtrate for conditioning; complex mix, check allergens and preservative residues
- Trisodium Ethylenediamine Disuccinate
- Mild chelator replacing EDTA; water-soluble, very low irritation, stabilizes metal ions
- Dehydroacetic Acid
- Broad-spectrum preservative for acidic and oil-based systems; has concentration limits, requires challenge testing.
- Caffeine
- Active ingredient, 0.1–2%; promotes circulation, irritation risk at high concentration.
