Oct 18, 2013· Magnesium stearate is a salt that is produced when a magnesium ion bonds with two stearate molecules. Stearate is just the anion form of stearic acid, which you've most likely heard of before. Stearic acid is a long-chain saturated fat that is abundant in beef, cocoa butter, coconut oil, and other natural foods.

Sep 04, 2019· Magnesium stearate is a magnesium salt of stearic acid. Essentially, it's a compound containing two stearic acids and magnesium. Stearic acid is a saturated fatty acid found in many foods, including animal and vegetable fats and oils. Cocoa and flaxseeds are examples of foods that contain substantial amounts of stearic acid.
Ingredients -- Sorbitan monostearate Chemical Formula: Sorbitan monostearate. Synonyms. SPAN 60 Description. Wax-like creamy white powder. Sorbitan monostearate is an ester of sorbitol and stearic acid. The sorbitol end of the molecule is very soluble in water. The stearic acid end is soluble in fats.

sorbitol is first dehydrated to sorbitan and then esterified with acid or alkaline catalysis . Sorbitol for use may be D-sorbitol in the form of white powder. The fatty acid for use may be any fatty acid, Specific example stearic acid. The esterification of sorbitol condensate with fatty acid …
These methods include transesterification of sorbitol with methyl, ethyl or glycerol fatty acid esters (U.S. Pat. Nos. 5,458,910 and 5,612,080), enzyme catalyzed direct esterification of sorbitol with fatty acids (U.S. Pat. No. 4,614,718), and acylation of sorbitol with a fatty acid chloride or anhydride.

21 CFR 173.310 - Boiler water additives. Sorbitol anhydride esters: A mixture consisting of sorbitan monostearate as defined in § 172.842 of this chapter; polysorbate 60 ((polyoxyethylene (20) sorbitan monostearate)) as defined in § 172.836 of this chapter; and polysorbate 20 ((polyoxyethylene (20) sorbitan monolaurate)),.
Sorbitan monostearate. Sorbitan monostearate is an ester of sorbitan (a sorbitol derivative) and stearic acid and is sometimes referred to as a synthetic wax. It is primarily used as an emulsifier to keep water and oils mixed. Sorbitan monostearate is used in the manufacture of food and healthcare products and is a non-ionic surfactant.
PRODUCT NAME : Sorbitan Monostearate (E491) SYNONYMOUS: SMS; Sorbitan Esters CLASS : Emulsifier DESCRIPTION AND INGREDIENTS : They are partial products of stearic acid and sorbitol and anhydrides. It may have sorbitol esters and free fatty acids.
Apr 01, 2019· Sorbitol anhydride esters: A mixture consisting of sorbitan monostearate as defined in 172.842 of this chapter; polysorbate 60 ((polyoxyethylene (20) sorbitan monostearate)) as defined in 172.836 of this chapter; and polysorbate 20 ((polyoxyethylene (20) sorbitan monolaurate)), meeting the specifications of the Food Chemicals Codex, pp. 825-827.
The Food and Drug Administration (FDA) is amending the food additive regulations to provide for the safe use of sorbitol anhydride esters, an emulsifier blend of sorbitan monostearate, polyoxyethylene (20) sorbitan monostearate (polysorbate 60) and polyoxyethylene (20) sorbitan monolaurate (polysorbate 20) as an anticorrosive agent in boilers where steam may contact food.
Synthesis. Sorbitan is produced by the dehydration of sorbitol and is an intermediate in the conversion of sorbitol to isosorbide. The dehydration reaction usually produces sorbitan as a mixture of five- and six-membered cyclic ethers (1,4-anhydrosorbitol, 1,5-anhydrosorbitol and 1,4,3,6-dianhydrosorbitol) with the five-membered 1,4-anhydrosorbitol.
Apr 01, 2019· Sec. 172.842 Sorbitan monostearate. The food additive sorbitan monostearate, which is a mixture of partial stearic and palmitic acid esters of sorbitol anhydrides, may be safely used in or on food in accordance with the following prescribed conditions:
DEFINITION Polyoxyethylene (20) sorbitan monostearate consists of a mixture of the partial esters of sorbitol and its mono- and dianhydrides (which have an acid value below 10 and a water content below 0.2%) with the food-grade stearic acid and condensed with approximately 20 moles of ethylene oxide per mole of sorbitol and its anhydrides.

Scheme 1. Polymerization reaction of citric acid and sorbitol through an anhydride intermediate. Citric acid can then undergo further condensation, and the resulting crosslinking can give an insoluble material under certain conditions. Under most con-ditions, D-sorbitol can also lose water to also form an anhydride. (The terminal hydroxy group on the sorbitol is shown to react for clarity. A reaction at the …
