Calcium stearate, also known as calcium stearate, calcium stearate, Calcium stearate or Calcium Distearate, is a white to pale yellow powdery substance that is made up of stearic acid and calcium ions. It is insoluble in water but soluble in ethanol, ether and fatty materials. Calcium stearate is characterised by its important properties, which include high chemical stability, resistance to oxidation and the ability to reduce friction.

Calcium stearate is found in a wide range of products that we commonly use in our daily lives. In particular, it is used in the food industry as an anti-caking additive that improves the consistency and texture of food. Calcium stearate is primarily used in the baking and confectionery industry, as well as in the dairy industry. Calcium stearate is also often used in the cosmetics industry, specifically as a stabiliser in emulsions, where it acts as an emulsifier to improve the consistency of cosmetic products. Its uses also include the plastics and rubber industries, where it acts as a lubricant and prevents the bonding of products made from these materials.
