Hydroxypropyl Methylcellulose, commonly known as HPMC, is a versatile and essential synthetic polymer derived from cellulose. Appearing as a white to off-white granular powder, HPMC is a non-ionic cellulose ether widely recognized for its multi-functional properties across numerous industries. NINGBO INNO PHARMCHEM CO.,LTD. stands as a reliable manufacturer and supplier of high-quality HPMC, offering solutions that meet diverse industrial demands.

HPMC distinguishes itself through a unique combination of characteristics. As a non-ionic compound, it is highly soluble in water, forming colloids that exhibit excellent thickening, binding, and film-forming capabilities. A notable property is its thermal gelation, where aqueous solutions congeal into a semi-flexible mass upon reaching a critical temperature. This unique attribute, combined with its metabolic inertness, enzyme resistance, low odor and taste, and pH stability, makes HPMC an ideal additive. It also functions effectively as a surfactant, protective colloid, lubricant, and emulsifier, alongside its primary role as a water retention agent and suspension aid. Its high tolerance to both salt and alcohol further broadens its application scope.

In the construction industry, HPMC is indispensable, primarily in dry mortar formulations such as tile adhesives, cement renders, and gypsum products. Its excellent water retention properties are critical, effectively preventing mortar from rapid water loss, which can lead to premature drying and cracking. This ensures an extended opening time and adjustment period for the mortar, significantly improving workability. Furthermore, HPMC's thickening effect allows for optimal consistency, enhancing mortar cohesion and providing an anti-sagging effect. This leads to greatly improved construction efficiency and better bonding strength, even in high-temperature environments, by ensuring sufficient moisture for full cement hydration.

HPMC plays a vital role in pharmaceuticals, serving as an excipient in oral tablet and capsule formulations where it acts as a controlled-release agent, delaying the release of medicinal compounds into the digestive tract. It is also used as a binder and a component of tablet coatings. In ophthalmic applications, HPMC solutions are utilized as a semi-synthetic tear-film substitute, aiding visual clarity and extending lubricant presence on the cornea, which helps alleviate eye irritation. As a food additive (E464), HPMC functions as an emulsifier, thickening and suspending agent, and is increasingly adopted as a vegetarian alternative to animal gelatin. Its ability to trap air bubbles, similar to gluten, also makes it a valuable ingredient in creating all-oat and other grain breads.

The cosmetic industry benefits from HPMC's multi-functional profile. It acts as a lubricant, foam enhancer, and stabilizer, contributing to richer, longer-lasting lather in surfactant systems. Moreover, it serves as a thickener, emulsion stabilizer, and film former in various hair and skin care products. Beyond these major sectors, HPMC finds application in paints and coatings, detergents, cleaners, and the manufacturing of contact lenses and Polyvinyl Chloride (PVC).
