1.What is Calcium Stearate?

Calcium stearate, the calcium salt of stearic acid derived from animal fats & oils or vegetable oils, with the chemical formula Ca(C18H35O2)2. It is a synthetic ingredient that can be used as an anti-caking agent, release agent, lubricant, binder, emulsifier, and thickener in food with the European food additive number E470a.

2.How is Calcium Stearate Made?

It can be produced as a white precipitate by the reaction between calcium chloride and sodium stearate in aqueous solution. The following is the chemical equation: CaCl2 + 2C17H35COONa → (C17H35COO)2Ca + 2NaCl It can also be made by reacting stearic acid with calcium oxide (2). The following is the chemical equation: 2C17H35COOH + CaO → (C17H35COO)2Ca + H2O

3.Is Calcium Stearate Safe to Eat?

Calcium stearate almost has no side effects when used as a food additive. It is generally recognized as safe (GRAS) in food with no limitation other than current good manufacturing practice by the FDA. It can be used as a flavoring agent & adjuvant, a lubricant & release agent, and a stabilizer and thickener. In Europe, calcium salts of fatty acids (E470a) are approved ingredients and its safety as food additives have been re-evaluated by the EFSA in 2018. The EFSA concluded that no safety concern at the reported uses and use levels, and no need to establish a numerical acceptable daily intake (ADI) of it.

4.What is Ferrous gluconate used for?

Calcium stearate is mainly used as an anti-caking agent in food, cosmetics and pharmaceuticals for its lubricating and water-repelling properties. Food：It can be used as a solid-phase lubricant to prevent ingredients and finished products from sticking caused by absorbing moisture. In bread, it is a dough conditioner that functions as a free-flowing agent, and is commonly used together with other dough softeners such as mono- and diglycerides.Cosmetics It is generally used for its lubricating properties. It maintains emulsions from separating into oil and water phases in cosmetics and personal care products. Pharmaceuticals It is an excipient that can be used as a mold-release agent (to help machines run fast) in the manufacturing of pharmaceutical tablets and capsules. Plastics Calcium stearate is used as a lubricant, release agent and an acid scavenger (to neutralize hydrochloric acid) in the manufacturing of plastics, e.g. vinyl polychloride (PVC) and polyethylene (PE). Other uses It can also be used in coating, paper, rubber, concrete, textile, an antifoaming agent and so on.
