Product Description

Medicine Grade Raw Material CAS54-21-7 Sodium Salicylate with Reasonable Price

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 with emulsifying, dispersing, and wetting properties[citation needed]. It is also employed to create synthetic fibers, metal machining fluid, and brighteners in the leather industry, and as an emulsifier in coatings, pesticides, and various applications in the plastics, food and cosmetics industries. Sorbitans are also known as "Spans".
Span 20 is sorbitan Dodecanoate, an amber oily liquid, which can be miscible with organic solvents and oils and form a galactic solution in water.
application
Span 20 can be obtained by the reaction of sorbitan and lauric acid. It can be used as tail reducer, emulsifier and wetting agent of gas chromatography stationary liquid and support.
purpose
1. As a non-ionic food emulsifier, it can be used alone or mixed with tween-60, tween-65 and Tween-80.
2. Used as emulsifier, lubricant, wetting agent, dispersant, thickener, etc
3. Non ionic surfactant, emulsifier, lubricant, desiccant, gas chromatographic stationary liquid, separation and analysis of oxygenated compounds.
Uses: used as emulsifier, lubricant, wetting agent, dispersant, thickener, non-ionic surfactant, emulsifier, lubricant, desiccant, gas chromatography stationary liquid, separation and analysis of oxygenated compounds.
