Calcium Stearate

Typical Product Characteristics

  • Ash content: 9.2 – 10.2 %
  • Free fatty acid: Max. 1.0 %
  • Moisture: Max. 3.0 %
  • Melting range: 150 – 160 °C

Calcium stearate is recognized as physiologically safe, and is insoluble in most solvents. Compared to waxes, it has a relatively high softening point, and, consequently, do not become greasy at higher temperatures.

Calcium stearate is primarily used as an acid scavenger, release agent and lubricant in the plastics industry, for waterproofing in construction, and as an anti-caking additive in pharmaceuticals and cosmetics. In addition, Baerlocher has developed special thermostable calcium stearate products designed to withstand exceptionally high temperatures.
