Hydroxypropylmethylcellulose is a commonly used additive and has wide application in many industries. This article will introduce in detail the usage and dosage of hydroxypropyl methylcellulose to help readers better understand and master the use of it.

1. Introduction to Hydroxypropylmethylcellulose


Hydroxypropylmethylcellulose (HPMC) is a nonionic cellulose ether with excellent thickening, suspension, dispersion, emulsification, adhesion and other properties, and is relatively stable to heat and acid-base. Commonly used in pharmaceutical, food, cosmetics and other industries.


2. Usage of hydroxypropyl methylcellulose

1. Pharmaceutical industry: In the pharmaceutical industry, hydroxypropyl methylcellulose is mainly used to prepare capsules, tablets, pharmaceutical dosage forms, etc. Its excellent adhesive properties can improve the stability and release properties of drugs. The preparation method is to mix the drug evenly with hydroxypropyl methylcellulose and other auxiliary materials, and then dry it and press it into a tablet or make a capsule. When using it, you should pay attention to the nature and content of the drug and its compatibility with hydroxypropyl methylcellulose to avoid affecting the efficacy of the drug.

2. Food industry: In the food industry, hydroxypropyl methylcellulose is mainly used to improve the taste, texture and stability of food. For example, adding an appropriate amount of hydroxypropyl methylcellulose to ice cream, dairy products, beverages, etc. can play a role in thickening, stabilizing and emulsifying. When using it, you should pay attention to the formula and processing technology of the food, as well as the amount of HPMC added, so as not to affect the nutritional composition and taste of the food.

3. Cosmetics industry: In cosmetics, hydroxypropyl methylcellulose is mainly used in the production of lotions, creams, facial masks and other products. Its thickening, dispersing and stable properties can improve product quality and stability. When using it, you should pay attention to the compatibility and compatibility with other ingredients of cosmetics, as well as the impact of the amount added on product performance.


3. Dosage of hydroxypropylmethylcellulose

When using hydroxypropylmethylcellulose, the dosage should be determined according to the specific application scenario and requirements. Generally speaking, according to product formulation and process requirements, the optimal amount of addition can be selected through experiments. The following are the reference dosages in general:

1. Pharmaceutical industry: According to the properties and dosage form requirements, the general added amount is 0.5%~10%. The specific dosage should be determined based on actual conditions.

2. Food industry: According to the type of food and processing technology, the general addition is 0.1%~2%. The specific dosage should be determined based on actual conditions.

3. Cosmetics industry: According to product formula and requirements, the general amount of addition is 0.5%~5%. The specific dosage should be determined based on actual conditions.
