The Importance of Solubility

Cosmetic Uses

Hydroxyethyl cellulose (HEC) is a water-soluble polymer derived from cellulose. It is commonly used in various industries, including pharmaceuticals, cosmetics, and construction, due to its rheological properties, film-forming capabilities, and ability to retain moisture. The Safety Data Sheet (SDS) for Hydroxyethyl Cellulose provides critical information regarding its properties, handling, safety precautions, and potential hazards associated with its use.

The heart of the HEC manufacturing process is the etherification reaction. In this step, the purified cellulose is reacted with ethylene oxide, a reactive ether compound. The reaction takes place in an alkaline medium, which typically involves sodium hydroxide (NaOH). The cellulose is first treated with a basic solution to produce alkali cellulose, which enhances its reactivity.

Chemical names Hydroxypropyl methyl cellulose, 2-hydroxypropyl ether of methyl cellulose
