Span 80 (Sorbitan Monooleate) | High-Purity Non-Ionic Emulsifier for Laboratory, Pharmaceutical, Cosmetic & Industrial Applications

Product Description

Span 80, chemically known as Sorbitan Monooleate, is a premium-quality non-ionic surfactant and emulsifying agent manufactured through the esterification of sorbitol with oleic acid. It is widely recognized for its exceptional emulsifying, dispersing, and stabilizing properties, making it an essential ingredient in pharmaceutical, cosmetic, food, laboratory, and industrial formulations.

Span 80 appears as an amber to yellow viscous liquid with a mild characteristic fatty odor. Due to its low Hydrophilic-Lipophilic Balance (HLB) value of approximately 4.3, it is highly effective in producing stable water-in-oil (W/O) emulsions. It is also commonly used together with Tween 80 (Polysorbate 80) to achieve balanced emulsification systems for specialized formulations requiring enhanced stability and consistency.

Its excellent lubricating properties, low toxicity, biodegradability, and chemical stability make Span 80 a preferred emulsifier across multiple industries. It is suitable for research laboratories, educational institutions, pharmaceutical manufacturers, cosmetic companies, food processing industries, paint manufacturers, textile industries, and chemical production facilities.

Whether you are developing pharmaceutical ointments, cosmetic creams, laboratory formulations, food emulsions, agricultural chemicals, or industrial lubricants, Span 80 provides reliable performance, excellent compatibility, and long-term formulation stability.
