What does Hydroxyethyl Cellulose do for skin?
Hydroxyethyl Cellulose (HEC) functions primarily as a non-ionic thickener, viscosity-increasing agent, film-former, and emulsion stabilizer in cosmetic formulations. It achieves this by forming a polymeric network in aqueous solutions through hydrogen bonding with water molecules, thereby increasing the solution's viscosity and creating a more stable product texture. When applied to the skin or hair, HEC can form a thin, transparent film, which contributes to sensory properties and can help reduce transepidermal water loss (TEWL) and enhance hydration by forming a mild occlusive barrier on the skin surface.
Typical concentration: 0.1-5% (most formulas use 0.5-2%)
Is Hydroxyethyl Cellulose safe?
Hydroxyethyl Cellulose is generally considered safe for use in cosmetics. The CIR Expert Panel has assessed its safety and concluded it is safe for use in cosmetic formulations. It is typically non-irritating and non-sensitizing.
