- Light, low-viscosity ester emollient; excellent spreadability, good for gels and light lotions
- Sodium Lactate Methylsilanol
- Not decoded yet
- PEG-6 Stearate
- Nonionic emulsifier; may cloud at low temp; match HLB; avoid cationic surfactants.
- Hordeum Distichon Extract
- Not decoded yet
- Imperata Cylindrica Root Extract
- Imperata root extract; traditional TCM ingredient for skin conditioning. No public data on irritancy or comedogenicity.
- PEG-32 Stearate
- Not decoded yet
- Aloe Barbadensis Leaf Juice
- Natural humectant and soother with high water activity; requires preservative system, generally well-tolerated
- Phellodendron Amurense Bark Extract
- Amur cork tree bark, alkaloid rich; mild irritant, control dosage, avoid strong acids.
- Santalum Album Extract
- Sandalwood extract; soothing claims, high risk for fragrance-allergic consumers

- Ascorbyl Tetraisopalmitate
- Vitamin C ester antioxidant; more stable than ascorbic acid but still light-sensitive.
- Tocopheryl Acetate
- Vitamin E derivative antioxidant at 0.1–1%; more stable than tocopherol, store protected from light
- Panthenol
- Panthenol (vitamin B5) at 1–5%; moisturizing and reparative, supports barrier recovery

- Soothing and anti-inflammatory agent, 0.01–0.1%; low irritation, good for sensitive skin.
- Sodium Acrylate/Acryloyldimethyl Taurate Copolymer
- Not decoded yet
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Carbomer
- Gelling thickener requiring neutralization; watch out for ion compatibility
- Isohexadecane
- Lightweight mineral-oil-derived emollient and solvent; low viscosity, non-comedogenic, improves texture
- Caprylyl Glycol
- Polyol conditioner and preservative booster at 0.5–3%; emollient feel, often paired with 1,2-hexanediol
- Sclerotium Gum
- Non-ionic gum for gels; neutral pH, requires dissolution via heating or fine milling
- Chlorphenesin
- Phenolic antimicrobial; strict EU limits apply, potential allergen, careful dosing required for leave-on products.
- Polysorbate 80
- Non-ionic emulsifier and solubilizer; watch for interaction with parabens
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Hydroxyethylcellulose
- Water-soluble cellulose ether for thickening and suspension stabilization; sensitive to ions, electrolytes reduce viscosity, use at pH 7-8.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Chlorhexidine Digluconate
- Antimicrobial agent often in oral care or antiseptics; residual odor noted; long-term use may cause resistance or sensitivity.
