Hydroxyethyl cellulose h e c

Manufactured by Dow

Sourced in China

Hydroxyethyl cellulose (H.E.C.) is a water-soluble polymer derived from cellulose. It is a multifunctional additive used in various industries, including construction, personal care, and pharmaceuticals. H.E.C. acts as a thickening, suspending, and stabilizing agent, enhancing the viscosity and rheological properties of aqueous formulations.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
