Hydroxyethyl Methylcellulose - HEMC/MHEC

Hydroxyethyl methyl cellulose (HEMC), also known as methyl hydroxyethyl cellulose (MHEC), is a non-ionic cellulose ether derived from natural, renewable sources such as wood pulp or refined cotton. It is produced by introducing ethylene oxide to methylcellulose.

Hydroxyethyl Methylcellulose - HEMC/MHEC

Landercoll® hydroxyethyl methyl cellulose (HEMC) is a non-ionic cellulose ether polymer based on cellulose, a natural polymer derived from refine cotton linter.
The degree of substitution and modification of substituent, allows the different chemical properties and benefits after alkalization and etherification reactions with Sodium hydroxide,Cholromethane,and ethylene oxide. HEMC is better performance in terms of higher gel temperature and hydrophilicity rely on ethyl substituent groups.
