Span 20 Food Additive Liquid Emulsifier
Sorbitan Monolaurate Emulsifier for Food and Cosmetics Applications
Product Overview
Sorbitan monolaurate, also known as Span 20, is a type of sorbitan ester derived from the reaction of sorbitol with lauric acid. This versatile emulsifier is part of the larger family of sorbitan fatty acid esters and serves as a surfactant, stabilizer, and emulsifying agent in various applications.
One of the key benefits of sorbitan monolaurate is its ability to reduce the amount of fat needed in some food products while improving overall quality and shelf life. E493 food additives help prevent separation and improve texture in various food products including baked goods, dairy products, and confections.
Sorbitan Monolaurate E493 is generally considered safe for consumption and is approved for use by regulatory agencies worldwide, including the U.S. Food and Drug Administration (FDA).
