Once the cellulose is activated, the hydroxyethylation reaction can take place. Ethylene oxide is added to the activated cellulose under controlled conditions, typically in a closed reactor system. The reaction occurs at elevated temperatures and pressures to ensure that the ethylene oxide effectively reacts with the hydroxyl groups of cellulose, resulting in the substitution of hydroxyethyl groups into the cellulose backbone. The reaction time, temperature, and ratio of reagents are meticulously controlled to achieve the desired degree of substitution, which influences the solubility and viscosity of the final product.

Hydroxyethylcellulose is used as a thickening agent for spray emulsions or suspensions in pesticide emulsion and suspension formulations. It can reduce the drift of pesticides and make them firmly adhere to the leaves of plants, thereby increasing the effect of foliar spraying. Hydroxyethyl cellulose can also be used as a film-forming agent in seed coatings and coating agents; as a binder and film-forming agent in tobacco leaf recycling.
One of the primary drivers of HPMC pricing is the cost of raw materials. HPMC is derived from cellulose, which is predominantly sourced from wood pulp or cotton. The pricing of cellulose can be impacted by factors such as deforestation regulations, changes in agricultural policies, and fluctuations in cotton prices. As demand for sustainable sourcing increases, the costs associated with environmentally friendly practices may also rise, leading to higher production costs for HPMC. This necessity for sustainable practices may, in turn, translate into increased prices for end-users.
HPMC viscosity tables categorize the polymer based on its viscosity in aqueous solutions, often measured at a specific concentration (commonly 2% w/v) and temperature (typically 20°C). The table includes grades of HPMC, such as low, medium, and high viscosity, with corresponding viscosity values. These grades allow formulators to select the appropriate type of HPMC for their specific needs.
