The same applies to achieve the needed high viscosity together with an unobstructed (bubble-free) view through the media of the eye and an easy and simple injectability.

- 2. Bathroom and Kitchen Tiling In areas with high humidity and harsh conditions, HPMC maintains the tiles' adhesion and prevents mold growth.
- viscous solution helps to suspend the active ingredient and prevent sedimentation
- Hydroxyethylcellulose (HEC), a semi-synthetic polymer derived from cellulose, is a versatile material with an array of uses across various industries due to its unique properties. Its chemical structure, characterized by the substitution of hydroxyethyl groups onto the cellulose backbone, imparts it with water solubility, non-toxicity, and the ability to form thick gels. This article explores the diverse applications of HEC in detail.

Pharmaceuticals:
- One of the main advantages of HPMC is its ability to dissolve in cold water. This solubility makes HPMC easy to work with and versatile in formulations where cold water is preferred. The solubility of HPMC in cold water also allows for the preparation of suspensions, solutions, and gels without the need for heating. This can be beneficial in applications where heat-sensitive ingredients are present, as cold water solubility helps maintain the stability and integrity of the final product.
- HEC is also widely used in the food industry as a thickening agent and stabilizer
What is Hydroxypropyl Methylcellulose Used For?

Die Größe des Makromoleküls wird üblicherweise durch dessen Viskosität in 2-prozentiger wässriger Lösung charakterisiert; handelsüblich sind die HPMC-Typen 4M (für ca. 4.000 mPa·s), 15M (für ca. 15.000 mPa·s) und 100M (für ca. 100.000 mPa·s).[11]



The European Commission received a request from Association Management & Regulatory Services Ltd2 for re-evaluation of the product hydroxypropyl methyl cellulose, when used as a feed additive for all animal species (category: technological additives; functional groups: emulsifier, stabilizer, thickener, gelling agent or binder).
