Overview

Description

Hydroxyethyl cellulose is a gelling and thickening agent derived from cellulose. It is widely used in cosmetics, cleaning solutions, and other household products. Hydroxyethyl cellulose and methyl cellulose are frequently used with hydrophobic drugs in capsule formulations, to improve the drugs’ dissolution in the gastrointestinal fluids. This process is known as hydrophilization.Hydroxyethyl cellulose is one of the main ingredients in the lubricant KY Jelly. It is also a key ingredient in the formation of big bubbles as it possesses the ability to dissolve in water but also provide structural strength to the soap bubble.

Features

Fast hydration; Strong water-based adhesion; Insensitive to ions and pH; High salt tolerance; Surfactant Compatibility

Application

Used as adhesives, bonding aids, filling cement admixtures;Used as coatings and optical brightener additives, coating polymers, filter control additives;Used as wet strength enhancer, protective colloid, rebound and slip reducing agent, rheology control modifier;Used as a gelling and thickening agent in the development of biological structures for hydrophobic drugs
