1. Safe and Non - toxic
HPMC is derived from cellulose, a natural compound. It is non - irritating to skin, eyes, and mucous membranes, making it a safe ingredient in a variety of products, such as in food, cosmetics, and pharmaceuticals.
2. Highly Water - soluble
It has excellent water - solubility, making it suitable for products that require water retention and adhesion. In the food and pharmaceutical industries, it is commonly used as a binder and disintegrant.
3. Excellent Film - forming Ability
HPMC can form tough, smooth, and aesthetically pleasing films. In the pharmaceutical industry, it is used for coating tablets and capsules, which can increase the stability of drugs against light, heat, and moisture.
4. Good Viscosity and Thickening Properties
It can give products a thick and smooth texture. In the food industry, it is used to thicken sauces; in the cosmetic industry, it is used to thicken lotions.
5. Water - retention Capacity
In construction, especially in cement - based materials, HPMC can improve water - retention. This helps to ensure optimal curing and bonding strength, preventing issues like poor solidification and cracking caused by excessive drying.
6. Viscosity Regulability
Different viscosity derivatives of HPMC can be blended in different proportions, and its viscosity can change according to certain rules, which allows for flexi
ble selection according to specific requirements.
