Regulation (EC) No 1831/20031 establishes the rules governing the Community authorisation of additives for use in animal nutrition. In particular, Article 10(2) of that Regulation also specifies that for existing products within the meaning of Article 10(1), an application shall be submitted in accordance with Article 7, at the latest one year before the expiry date of the authorisation given pursuant to Directive 70/524/EEC for additives with a limited authorisation period, and within a maximum of seven years after the entry into force of this Regulation for additives authorised without a time limit or pursuant to Directive 82/471/EEC.
The hydroxypropyl groups on HPMC allow it to interact with water molecules, forming a protective hydration layer around the polymer chains. This hydration layer prevents the HPMC particles from coalescing, ensuring they remain dispersed.
1. Food Industry In food production, HPMC is often employed as a thickener, stabilizer, and emulsifier. It enhances the texture of baked goods, sauces, dressings, and dairy products. Furthermore, its ability to retain moisture helps improve the shelf life of food items. HPMC is also utilized in gluten-free and low-calorie foods, providing a desirable mouthfeel without adding significant calories.

Overall, the price of hydroxyethyl cellulose is influenced by a complex interplay of factors, including market demand, production costs, and quality. While these factors can cause the price of HEC to fluctuate, it remains a popular choice for a wide range of applications due to its unique properties and versatility. As demand for HEC continues to grow, suppliers will need to carefully balance these factors to ensure a steady supply of high-quality HEC at a competitive price.
Where Can I Buy Hydroxyethyl Cellulose?
HPMC is synthesized from cellulose, a natural polymer derived from plant sources. By modifying cellulose with hydroxypropyl and methyl groups, HPMC comes to exhibit properties that are distinct from its parent compound. The degree of substitution of hydroxypropyl and methyl groups influences its solubility, viscosity, and thermal stability. Generally, HPMC is available in various grades, which differ in their viscosity and solubility levels, allowing for tailored applications across diverse sectors.
