1. What is HPMC?
（1）HPMC stands for Hydroxypropyl Methyl Cellulose,Hypromellose. It is a non-ionic water-soluble methyl cellulose ether polymer that is derived from natural polymer cellulose. HPMC is an odorless, non-toxic,tasteless white powder that can be dissolved in hot and cold water to form a transparent viscous solution.HPMC has the properties of thickening, binding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, surface active, water retention and protecting colloid that is commonly used in a variety of industries, including construction, pharmaceuticals, cosmetics, and food.

（3）HPMC Features :
①. Solubility: It is almost insoluble in absolute ethanol, ether, and acetone, but dissolves into a clear or slightly turbid colloidal solution in cold water. Soluble in some organic solvents, also soluble in water-organic solvent mixed solvents.
②. Salt resistance: in the presence of metal salts or organic electrolytes, it is relatively stable in aqueous solution.
③. Surface activity: it can be used as colloidal protective agent, emulsifier and dispersant.PH value is relatively stable in the range of 3.0~11.0. The viscosity of aqueous solution is hardly affected by acid or alkali.
2. What is HPMC used for?
HPMC is a versatile polymer with a wide range of applications. Its unique properties make it a valuable ingredient in various industries, contributing to the development of innovative products that meet the needs of consumers.
(1) Construction: One of the main applications of HPMC is in the construction industry. HPMC is used as a thickener, binder, and water retention agent in cement-based materials, mortar, and tile adhesives. It helps to improve workability, adhesion, and durability of these materials. HPMC also enhances the cohesiveness of dry mortars and increases the water retention properties of the materials, which helps to prevent cracking and improve the performance of the final product.
(2) Pharmaceuticals: HPMC is widely used in the pharmaceutical industry as a coating agent for tablets and capsules. It helps to protect the active ingredients from moisture and light, as well as improve their dissolution rate. HPMC is also used as a binder in tablet formulations, which helps to ensure that the tablet remains intact until it reaches the intended site of action. HPMC is also used as a suspending agent in liquid dosage forms and as a lubricant in capsules and tablets.
(3) Personal care products: HPMC is used in personal care products, such as shampoos, lotions, and creams, as a thickener and emulsifier to improve their texture and stability. HPMC helps to improve the viscosity of the products, which makes them easier to apply and provides a better sensory experience for the user. HPMC is also used as a film-forming agent in hair styling products and as a stabilizer in skin creams and lotions.
(4) Food: HPMC is used as a food additive to improve the texture and consistency of products such as sauces, dressings, and baked goods. It is also used as a fat replacer in low-fat and reduced-calorie foods. HPMC is a safe and non-toxic additive that is approved by regulatory authorities around the world. It helps to improve the mouthfeel of the products and provides a better sensory experience for the consumer.
(5) Paints and coatings: HPMC is used as a rheology modifier in paints and coatings to control the viscosity and improve their performance. It helps to improve the flow and leveling of the products and provides better film-forming properties. HPMC is also used as a thickener and stabilizer in water-based paints, which helps to improve their shelf life and prevent the settling of pigments.
(6) Oil and gas drilling: HPMC is used as a viscosifier and fluid loss control agent in oil and gas drilling fluids. It helps to improve the rheological properties of the drilling fluids, which enables better drilling performance and wellbore stability. HPMC also helps to prevent fluid loss in porous formations, which helps to reduce the risk of formation damage and wellbore instability.
