Overview
-
Chemical NatureNon-ionic surfactant derived from sorbitan and lauric acid.
-
Appearance & SpecsViscous amber liquid | HLB Value: 8.6
-
★ Primary Application (Yeast)Industry-Standard Protectant. Preserves cell viability for Instant Dry Yeast during drying and acts as a rehydration aid.
-
Cosmetics UseFunctions as a light, non-greasy emollient.
-
Key FunctionsWetting agent & Rehydration aid.
Molecular Structure
-
Structural ComponentsHydrophilic Backbone: Sorbitan (derived from sorbitol dehydration).Hydrophobic Moiety: Lauric acid (C12 fatty acid) esterified to sorbitan.
-
★ Mechanism of ActionAmphiphilic Nature. The structure allows the compound to align perfectly at oil-water interfaces. This effectively reduces surface tension and stabilizes emulsions.

Applications:
- Dry Yeast Manufacturing: Added to yeast prior to drying to protect cell membranes and facilitate rapid rehydration when used by bakers.
- Cosmetics & Skincare: A low-HLB co-emulsifier used in lightweight lotions and creams to improve spreadability without a greasy feel.
- Food Antifoaming: Acts as an antifoaming agent in sugar processing and milk production.
- Industrial Lubricants: Used as a rust inhibitor and lubricant additive in metalworking fluids due to its surface-active lauric chain.
Yeast Cell Protection
Span 20 forms a protective film around yeast cells, significantly improving their survival rate during the drying process and restoring activity quickly upon rehydration.
Superior Wetting Agent
With its lauric acid backbone, it offers excellent wetting properties, helping powders (like milk powder or cocoa) disperse instantly into water without clumping.
Light Texture (Cosmetics)
Unlike heavier stearate emulsifiers, Monolaurate provides a ‘light’ and dry skin feel, making it ideal for formulating non-greasy lotions and sunscreens.
HLB 8.6 Co-Emulsifier
Functions as a perfect bridge between oil and water phases. When paired with Polysorbate 20 (Tween 20), it creates highly stable, fine-textured emulsions.
