Hydroxypropyl Methyl Cellulose (HPMC), with the CAS number 9004 - 65 - 3, is a non - ionic cellulose ether derived from natural cellulose. Our factory supplies high - quality HPMC at the best price.
Physical and chemical properties: It is a white to off - white powder, odorless and tasteless. The viscosity range can vary from low to high, typically from 5 to 200,000 mPa·s. The methoxyl content is around 19% - 30%, and the hydroxypropyl content is about 4% - 12%. It has good solubility in cold water, forming a clear and viscous solution, but is insoluble in hot water, ethanol, ether, and chloroform.
In the construction industry, HPMC is widely used in cement - based products such as tile adhesives, plaster, and mortar. It can improve the workability, water retention, and adhesion of these materials, reducing cracking and enhancing durability.
In the pharmaceutical field, it serves as a film - coating agent for tablets, a thickener in suspensions, and a binder in capsules. Its excellent film - forming properties and biocompatibility make it a popular choice.
In the food industry, it is used as a stabilizer, thickener, and emulsifier. It can improve the texture of food products, prevent oil - water separation, and extend the shelf - life.
In the personal care industry, HPMC can be found in products like shampoos, conditioners, and lotions. It provides a smooth and creamy texture, enhances the stability of formulations, and improves the sensory experience of the products.
When using HPMC in construction materials, first add the required amount of water to the mixing container. Then, slowly add HPMC powder under continuous stirring to prevent clumping. Continue stirring for at least 10 - 15 minutes until a homogeneous solution is formed. Let the solution stand for a few minutes to allow the viscosity to develop fully before use.
In pharmaceutical applications, for film - coating, dissolve HPMC in a suitable solvent such as water or a mixture of water and alcohol. Adjust the viscosity of the solution according to the coating equipment requirements. Apply the coating solution onto the tablets using a coating machine.
In food and personal care products, HPMC should be dispersed in the liquid phase under high - speed agitation. Heat may be applied to facilitate dissolution in some cases. After dissolution, the solution can be further processed with other ingredients to form the final product.
Case 1: Construction - Tile Adhesive
A construction company was facing issues with poor adhesion and high water loss in their tile adhesives. They decided to use our HPMC. After adding the appropriate amount of HPMC to their formulation, the workability of the tile adhesive improved significantly. The tiles could be easily positioned, and the adhesion strength increased by 30%. Moreover, the water retention property of the adhesive was enhanced, reducing the drying time and preventing cracking.
Case 2: Pharmaceutical - Tablet Coating
A pharmaceutical manufacturer was looking for a reliable film - coating agent for their new tablet product. They chose our HPMC. The HPMC - based coating solution was easy to prepare and had excellent film - forming properties. The coated tablets had a smooth and uniform appearance, with good resistance to moisture and light. The dissolution rate of the tablets met the quality standards, ensuring the effectiveness of the medication.
Case 3: Food - Salad Dressing
A food company wanted to improve the stability and texture of their salad dressing. By incorporating our HPMC as an emulsifier and stabilizer, they were able to prevent oil - water separation. The salad dressing had a creamy and smooth texture, which enhanced the consumer experience. The shelf - life of the product was also extended, reducing spoilage and waste.
