Redispersible powder polymer is a popular additive in a wide range of construction materials. It is a white, free-flowing powder that can be easily mixed with water to form a stable emulsion. This versatile polymer has many applications in the construction industry, from improving the performance of mortar and cement to enhancing the properties of tile adhesives and grouts. One of the key advantages of redispersible emulsion powder is its ability to improve the performance of cement-based products. When added to mortars, plasters, and other construction materials, this powder enhances their workability, adhesion, and flexibility. This results in a higher quality end product that is more durable and resistant to cracking.

When the formulation is applied to a substrate, the water evaporates, and HPMC forms a continuous film on the surface. This film provides adhesion, cohesion, and improved workability to the construction material. The thickening property of HPMC is a result of its long and flexible polymer chains, which entangle and interact with other particles in the formulation, leading to increased viscosity.

Hydrocolloids, a class of water-soluble polymers, play a significant role in various industries, particularly in pharmaceuticals, food, and cosmetics. Two prominent members of this group are Hydroxyethyl Cellulose (HEC) and Hydroxypropyl Methylcellulose (HPMC). Though they share similarities in their chemical structure and functionality, they exhibit distinct properties that make them suitable for different applications.

Cellulose is the most frequent polysaccharide in nature consisting of (some hundreds up to ten thousands) β-glycosidic linked glucose molecules. It is the main constituent of plant cell walls and vegetable fibre. It occurs mostly associated with hemicelluloses and lignin. It is therefore a common component of plant-based feed for all food producing and companion animals. However, these animals are not capable to digest cellulose enzymatically due to the lack of cellulases. The monomer element of cellulose, glucose, will not be released from cellulose. But gastrointestinal microbes can split cellulose, the main degradation products are short-chain fatty acids. In a simplified view, monogastric animals cannot digest cellulose, small amounts are microbially degraded in the large intestine. Minor amounts of cellulose may be absorbed as such by paracellular transport (passing through the intercellular space) or by transcytosis (transcellular transport of macromolecules captured in vesicles). On the other side, animals with large fermentation chambers in the intestine, such as ruminants, horses and rabbits, utilise large amounts of cellulose as energy source. In summary, cellulose is a natural part of feed and plays a physiological role in nutrition of animals (see Section 3.2.1).

In conclusion, Cellulose ether Hydroxypropyl Methylcellulose (HPMC) is a unique and versatile polymer that offers a wide range of benefits in various industries. Its gel-forming properties, thickening abilities, and compatibility with other ingredients make it an essential ingredient in pharmaceuticals, food, construction, and personal care products. As a non-toxic and biodegradable polymer, HPMC is a sustainable and environmentally friendly choice for formulators looking to enhance the performance of their products. In the pharmaceutical sector, HEC serves as a binder, disintegrant, and viscosity enhancer in tablet formulations degree of substitution (DS) and molecular weight (MW) of HPMC can be tailored
