- One of the key advantages of hydroxyethylcellulose is that it is safe and non-toxic, making it suitable for use in a wide range of products. It is considered a gentle ingredient that is unlikely to cause irritation or allergic reactions, making it ideal for sensitive skin types. Its compatibility with other ingredients also makes it a popular choice for formulators looking to create high-quality and effective products.
- This modification results in a more hydrophilic polymer compared to unmodified cellulose, which significantly enhances its solubility in water. The hydroxyethyl substituents disrupt the strong hydrogen bonding between cellulose chains, reducing the overall crystallinity and making the polymer more accessible to water molecules. As a result, HEC readily dissolves in cold water, forming viscous solutions that exhibit pseudoplastic behavior—they flow easily when stirred but become thicker when left to stand.
- In the construction industry, HPMC is used as an additive in concrete and plaster products. It helps to improve workability, reduces cracking, and increases water resistance. HPMC can also be used as a coating on the surface of concrete, providing a protective layer that prevents moisture penetration and enhances durability.
What do I do if I miss a dose?
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.
HPMC is used as a thickening, emulsifying, and film-forming agent in creams, lotions, and shampoos. It is also used as a suspending agent in toothpaste and as a lubricant in makeup products.
