- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- PEG-40 Hydrogenated Castor Oil
- Solubilizer and emulsifier for oil-soluble ingredients; high concentrations may cause contact dermatitis in sensitive skin.
- Polysorbate 20
- Non-ionic emulsifier and cleansing surfactant; contains PEG, control microbial load.
