Summary

Hydroxyethyl cellulose is an ingredient used in formulations to alleviate irritation of the skin.

Generic Name
Hydroxyethyl cellulose
DrugBank Accession Number
DB11602
Background

Hydroxyethyl cellulose is a polysaccharide derivative with gel thickening, emulsifying, bubble-forming, water-retaining and stabilizing properties. It is used as a key ingredient in many household cleaning products, lubricants and cosmetics due to its non-ionic and water-soluble nature. It is often used as an ingredient in ophthalmic pharmaceutical preparations such as artificial tear solutions and adjunct agent in topical drug formulations to facilitate the delivery of drugs with hydrophobic character.

Pharmacodynamics

Hydroxyethyl cellulose acts as a demulcent by relieving inflammation or irritation and dryness of eyes. It acts as one of the key ingredient and viscosity-enhancing agent to prolong corneal contact time and increase intraocular drug levels 4.

Mechanism of action

Interacts with the solid surface through hydrogen bonding to thicken and prolong the formation time of a water-retaining film. Hydroxyethyl cellulose acts as a drug carrier or microsphere to entrap other drug molecules and form a viscous gel-like dispersion, enabling drug diffusion across biological membranes 3.
