Description
A waxy white powder first isolated for commercial use in 1924. Calcium stearate is used industrially as a Flatting agent in paints, a waterproofing agent in cements, and as a solid-phase Lubricant for plastics. For foods, calcium stearate is used as a bread dough conditioner, an Emulsifier, an anti-dusting agent, a thickener, and as a Release agent.
