- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Glyceryl Polyacrylate
- Water-soluble film former at 1–5%; light feel, soluble in polyols, non-occlusive
- Silk Amino Acids
- Silk amino acids for humectancy and hair/skin care; low molecular weight, easily absorbed
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Chondrus Crispus
- Crisp chondrus seaweed extract; often used as thickener or skin conditioner; labeled as fragrance or conditioner, check formulation context.
- Glucose
- Low-MW humectant and buffer; high hygroscopicity requires careful preservation and humidity control.
- Squalane
- Emollient from plants or synthetic; light texture
- Propylene Glycol
- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Phospholipids
- Biomimetic repair and emollient, mimics skin lipids; typically processed at low temps, may be sticky at high levels
- Lactis Proteinum
- Not decoded yet
- Glyceryl Linoleate
- Glyceryl linoleate; emulsifier and emollient; oxidation-prone, requires antioxidants
- Parfum
- Fragrance for scent; may contain allergens, caution for sensitive skin, full labeling required.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Methylparaben
- Preservative, narrow spectrum; often combined, check allergen risk and regulatory limits.
- Butylparaben
- Butylparaben preservative; low concentrations; potential endocrine concerns, regulatory limits apply.
- Ethylparaben
- Paraben preservative; EU restricted, watch total load and sensitive skin reactions
- Propylparaben
- Medium-chain preservative; restricted use, pH-sensitive efficacy.
- Isobutylparaben
- Paraben preservative; used in combination, restricted usage
