The additive sorbitan monolaurate consists of sorbitol (and its anhydrides) esterified with fatty acids derived from coconut oil. It is intended to be used as a technological additive, functional .
name the carboxylic acid and replace word 'acid' with word 'anhydride'; e.g. ethanoic acid becomes ethanoic anhydride (aka acetic acid becomes acetic anhydride) anhydride reaction: hydrolysis react readily with water to give two carboxylic acids.
Sorbitan monostearate 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 with emulsifying, dispersing, and wetting properties .
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.
Before a company can use EWG VERIFIEDTM on such products, the company must show that it fully discloses the products' ingredients on their labels or packaging, they do not contain EWG ingredients of concern, and are made with good manufacturing practices, among other criteria.
