Calcium Stearate#1592-23-0 Application
Calcium stearate has a wide range of applications, covering various fields such as food, daily necessities, textiles, and building materials. Its specific uses can be classified into the following categories:
1. In the food and candy industry: It is used as a powder flow agent and surface conditioner. For example, in products like Smarties chocolate beans and Sprees hard candies, it can improve the powder flowability and optimize the surface condition of the food.
2. In the daily necessities industry: It can act as a lubricant and is used in the production of pencils and crayons; it is also a waterproofing agent for fabrics, enhancing the waterproof performance of the fabric.
3. In the concrete industry: It has two main functions. One is to control the performance of the cementitious products used in the production of concrete masonry (such as spreaders, blocks), and the other is to provide waterproofing effects for related concrete products.
