Product Description
Span emulsifiers, a series of sorbitan fatty acid esters, are nonionic surfactants widely used as water-in-oil (W/O) emulsifiers due to their hydrophobic-lipophilic balance (HLB) values ranging from 1.8 to 8.6, depending on the fatty acid chain length and esterification degree. These compounds are derived from sorbitol and fatty acids (e.g., lauric, palmitic, stearic, or oleic acids), forming products such as Span 20, Span 40, Span 60, Span 80, and Span 85. They are characterized by excellent thermal stability, hydrolysis resistance, and compatibility with other surfactants.
Key Features of Span Emulsifiers
Versatile HLB Range:
Span 20 (HLB 8.6): Higher hydrophilicity, suitable for dispersing agents and mild emulsification.
Span 60 (HLB 4.7) and Span 80 (HLB 4.3): Ideal for W/O emulsions, with strong emulsifying and stabilizing properties.
Span 85 (HLB 1.8): Extremely lipophilic, used in specialized industrial applications.
Physical Properties:
Appearance varies from amber oils (e.g., Span 80) to waxy solids (e.g., Span 60), depending on the fatty acid component.
Soluble in organic solvents (e.g., ethanol, mineral oil) but insoluble in water.
Safety & Compliance:
Generally recognized as safe (GRAS) for food use, with low toxicity (e.g., Span 60 and 80 are approved under GB standards in China). LD50 in mice is 10 g/kg, and ADI is 0-25 mg/kg body weight.

Food Industry
Bakery & Confectionery:
Improve dough elasticity, prevent starch retrogradation, and extend shelf life in bread and cakes (usage: 0.5-10% of flour weight).
Stabilize cocoa butter in chocolate to prevent fat bloom (usage: 0.1-0.3%).
Dairy & Ice Cream:
Enhance emulsification and aeration in ice cream, ensuring smooth texture and heat stability (usage: 0.2-0.5%).
Stabilize plant-based milk substitutes (e.g., soy milk) to prevent oil-water separation.
Edible Coatings:
Used as fruit and vegetable coatings to retain freshness and reduce moisture loss.
