Calcium Stearate Cas1592-23-0 | E470a | Anti-Caking Agent & Tableting Lubricant

Product Overview

Calcium Stearate (E470a) is a fine white powder serving as anti-caking agent and tableting lubricant for food and dietary supplement manufacturing. It optimizes powder flowability, prevents sticking during tablet compression, and reduces tablet capping and chipping. It is commonly used in mineral premixes, dietary supplement tablets and pressed candies.

Character

1.Fine white powder, odorless, insoluble in water.

2.Excellent lubricating performance for tableting process, effectively lowering friction between powder and tablet die.

3.Good anti-caking property, helping free-flow of blended vitamin and mineral powders.

4.High thermal stability, remains stable under normal tableting and drying temperature.

5.Low addition dosage, does not affect the color, flavor or nutritional value of finished products.

6.Compatible with most vitamin and mineral raw materials in powder blends.

7.Food grade and pharmaceutical grade comply with global standards for food additives.

Main Functions

1.Tablet Lubricating Function: Acts as tableting lubricant to reduce friction between powder and die, prevent sticking during tablet pressing, deliver smooth tablet surface.

2.Anti-Caking & Flow-promoting Function: Improves powder flowability and prevents powder agglomeration in vitamin and mineral premixes.

3.Mold Release Function: Provides good mold release property, reduces chipping and capping of finished tablets.

4.Stabilizing Function: Maintains physical stability of powder blends during storage, protects powder mixture texture.

Applications

1.Food & Dietary Supplement Industry 

Calcium Stearate is widely used in dietary supplement tablets, multivitamin mineral premixes and pressed candies. During tablet compression, it works as lubricant to avoid material sticking to punches and dies, minimizing tablet defects such as capping, chipping and surface marks. It also improves the flow characteristics of mixed powders, ensuring uniform feeding and consistent weight during tableting and powder filling.

2.Confectionery & Functional Solid Food 

Suitable for pressed candies, functional fortified solid food and nutritional granule formulations. It improves powder handling performance during production without altering the original taste and color of finished products.

3.Pharmaceutical Industry 

Pharma-grade Calcium Stearate is used as lubricant for oral tablet formulations, with limited consumption and not our primary business scope.
