Applications of Calcium Stearate 1 As a PVC stabilizer in non toxic formulations, when used with other metal soaps, epoxy and chelator ( food packaging, portable water pipes, etc. ) 2 Increase transparency when used with cadmium stearate 3 External and internal lubricant in rigid as well as plasticized compounds 4 In cosmetics 5 In grease 6 In paints and inks 7 Water proofing agent 8 In paper coating PAcking size = 10 kg in PP bags with inner PE liner Calcium stearate is carboxylate of calcium that is found in some lubricants and surfactants. It is a white waxy powder. Production and occurrence Calcium stearate is produced by heating stearic acid, a fatty acid, and calcium oxide: 2 C17H35COOH + CaO → (C17H35COO)2Ca + H2O It is also the main component of soap scum, a white solid that forms when soap is mixed with hard water.[2] Unlike soaps containing sodium and potassium, calcium stearate is insoluble in water and does not lather well.[citation needed] Commercially it is sold as a 50% dispersion in water or as a spray dried powder. As a food additive it is known by the generic E number E470. Applications Calcium stearate is used as a flow agent in powders including some foods (such as Smarties), a surface conditioner in hard candies such as Sprees, a waterproofing agent for fabrics, a lubricant in pencils and crayons. The concrete industry uses calcium stearate for efflorescence control of cementitious products used in the production of concrete masonry units i.e. paver and block, as well as waterproofing. In paper production, calcium stearate is used as a lubricant to provide good gloss, preventing dusting and fold cracking in paper and paperboard making.[4] In plastics, it can act as an acid scavenger or neutralizer at concentrations up to 1000ppm, a lubricant and a release agent. It may be used in plastic colorant concentrates to improve pigment wetting. In rigid PVC, it can accelerate fusion, improve flow, and reduce die swell. Applications in the personal care and pharmaceutical industry include tablet mold release, anti-tack agent, and gelling agent. Calcium stearate is a component in some types of defoamers. Calcium stearate is a non-toxic, white powdery substance. It is a calcium salt derived from stearic acid and is widely used in cosmetics, plastics, and pharmaceuticals. This salt is used as a plasticizer, stabilizer, and surfactant. It is a substance that the U.S. Food and Drug Administration has generally recognized as safe when used as a food additive. When certain types of fatty acids are heated with an alkaline substance, the resulting salt is known as soap. Stearic acid is one of the most widely used components of soaps. Calcium stearate is a synthetic ingredient formed through a reaction when stearic acid and calcium oxide are heated together. It is the most important type of calcium salt, but due to its lack of solubility, it is not commonly used in soap in modern times, having been replaced by synthetic substances that are water soluble. This substance is frequently found in cosmetics, however, especially aerosol hair styling products. It is also found in cosmetic powders, ointments, and packaging. Despite a very low risk for dermal irritation, topical contact may cause redness, itching, and eye irritation. Calcium Stearate is an insoluble salt of calcium, stearic acid and palmatic acid. In hard water, when soap of calcium ions is mixed, the scum that is formed is calcium stearate. Calcium stearate is non-toxic and has many applications as stabilizer and lubricant. Besides water, it is insoluble in water, ether, chloroform, acetone, cold alcohol as well. However, it is slightly soluble when dissolved in hot alcohol, hot vegetable and mineral oil. It shows good solublity in hot pyridine. The use of calcium stearate is seen widely as a stabilizer for PVC resins and lubricant for plastic moulding powders or tablets. Its use is recommended also in emulsions, cements, pencils, construction chemicals, paint flattening agent, resin coated sands and foundry chemicals, decaking agent in food items like onions and cosmetics. Use of calcium stearate is seen as a lubricating agent in paper and paperboard coating compositions, iron wire drawing and leather cloth manufacturing as well. Its use has been extended as a neutralizer, colour stabilizer, reducer of fiber breakage and de-agglomerator in PP and HDPE applications. Calcium stearate is also known as octadecanoic acid calcium salt, stearic acid calcium salt. Also available as Granular powder and Coarse powder. Butyl stearate is used as a flow agent in powders including some foods, a waterproofing agent for fabrics, and a lubricant in pencils and crayons. The concrete industry uses calcium stearate for efflorescence control of cementious products used in the production of concrete masonry units i.e. paver and block, as well as waterproofing. In the paper industry, calcium stearate is used as a lubricant to provide good gloss, preventing dusting and fold cracking in paper and paperboard making. In plastics, it can act as an acid scavenger, a lubricant and a release agent. Applications in the personnal care and pharmaceutical industry include tablet mold release, anti-tack agent and gelling agent. Suggested Application •As a stabilizer & lubricant in rigid PVC processing, PVC compounding & moulding, in Leather cloth manufacturing etc. • As a lubricant in iron wire drawing. • As an anti caking agent in Detergent Cakes. • In cosmetics.
