Once purified cellulose has been obtained, it undergoes an etherification process to introduce hydroxyethyl groups. This is primarily achieved through the reaction of cellulose with ethylene oxide in the presence of a catalyst, often a base such as sodium hydroxide. The reaction typically occurs in a controlled environment to ensure that the etherification is uniform and efficient.
Hydroxyethyl cellulose can dissolve in both cold water and hot water, but hot water can accelerate the dissolution process. Generally speaking, it is more appropriate to adjust the water temperature between 40 ° C and 70 ° C. Excessive water temperature may lead to HEC degradation, while excessively low water temperature may slow down the dissolution rate.
Before diving into the buying process, it’s crucial to understand what HPMC is and why it is used. HPMC is derived from natural cellulose, making it non-toxic and biodegradable. Its chemical structure allows it to absorb water, swell, and form a gel-like consistency, which is why it is favored in various applications. In the construction industry, for instance, HPMC is used in cement-based materials to improve workability and enhance adhesion. In pharmaceuticals, it serves as a binder and film-coating agent, and in the food industry, it is utilized as a thickener in sauces and dressings.
