HPC Hydroxypropyl Cellulose
product introduction
Hydroxypropyl Cellulose (Hydroxypropyl cellulose) is a non-ionic cellulose ether that appears as a white or white-like powder.
product characteristics
Excellent water solubility: it can be quickly dissolved in cold water to form a transparent and stable solution.
Good thermal stability: it can still maintain its stable performance at higher temperatures.
Surface activity: Has a certain surface activity, can improve the interface performance.
Good film formation: The film formed is tough, transparent and has good air permeability.
Wide compatibility: compatible with a variety of organic and inorganic compounds.
product use
Pharmaceutical industry: As an adhesive and film coating material for tablets, it can also be used to manufacture slow-release preparations.
For example, in some sustained-release tablets, the release speed of the drug is controlled to improve the efficacy.
Cosmetics: Used in lotions, creams and other products to increase consistency and stability.
Food industry: as a thickening agent, emulsifier and stabilizer, improve the texture and taste of food.
As in ice cream, to make it more delicate and smooth.
Building materials: can improve the adhesion and construction performance of mortar, putty, etc.
Production process
It is usually made from cellulose and propylene oxide by etherification under alkaline conditions.
Market prospects
With the rising demand for high-quality raw materials in various industries, Hydroxypropyl Cellulose has a promising market. Driven by strict standards in the pharmaceutical sector and innovative developments in the cosmetics and food industries, its market demand continues to grow.
use precautions
Storage should be placed in a dry, well-ventilated environment, avoid moisture and high temperature.
When dissolved, it should be gradually added and stirred to ensure full dissolution and avoid agglomeration.
According to different application scenarios and formulations, reasonable adjustment of the addition amount to achieve the best effect.
In short, Hydroxypropyl Cellulose plays an important role in many fields due to its excellent properties, providing strong support for the quality improvement and performance optimization of related products.
