Product Description

Product Description

Sorbitan Monooleate (Span 80) 

    Sorbitan Monooleate, commonly known by its commercial name Span 80, is a non-ionic surfactant and lipophilic emulsifier belonging to the sorbitan ester family . It is produced by the esterification of sorbitol (a sugar alcohol derived from renewable sources) with oleic acid (a fatty acid found in various vegetable oils) . Span 80 typically appears as an amber to brown viscous liquid with a characteristic faint fatty odor . Its molecular structure uniquely combines hydrophilic (sorbitan) and hydrophobic (oleic acid) components, giving it an amphiphilic nature . With a hydrophilic-lipophilic balance (HLB) value of approximately 4.3, it is preferentially oil-soluble and exceptionally effective at forming and stabilizing water-in-oil (W/O) emulsions . It is biodegradable, derived from renewable plant-based sources, and aligns with the principles of green chemistry .

Application

Cosmetics and Personal Care Industry

Food Industry

    Span 80 is a cornerstone ingredient in cosmetic formulations requiring stable water-in-oil emulsions . It is extensively used in cold creams, rich moisturizers, barrier creams, and water-resistant sunscreens to create a protective, non-greasy film on the skin . In these products, it ensures even distribution of water droplets within the oil phase, preventing separation during temperature fluctuations and storage . It also finds application in hair oils and leave-in treatments, where it helps distribute active ingredients evenly and enhances product spreadability and texture .

    As an approved food emulsifier (commonly designated as E494), sorbitan monooleate is used to stabilize emulsions in various food products . It is particularly effective in baked goods, confectionery items, dairy products, and sauces, where it improves texture, mouthfeel, and shelf stability . In plant-based protein beverages and hydrogenated vegetable oils, it acts as a stabilizer to prevent phase separation . For fruit and vegetable preservation, it can be used in coating formulations to extend freshness .

Pharmaceutical Applications

Textile and Fiber Processing

    In pharmaceutical formulations, Span 80 serves as a versatile excipient for stabilizing emulsions, suspensions, and oral dosage forms . It enhances the solubility and bioavailability of poorly water-soluble drugs by forming micelles or being incorporated into advanced drug delivery systems such as niosomes, transfersomes, and lipid-coated nanoparticles . Research has demonstrated its utility in transdermal delivery systems, vaccine adjuvants, and controlled-release formulations .

    In the textile industry, sorbitan monooleate functions as an effective emulsifier and lubricant . It is used in nylon and viscose cord oils to provide a smoothing effect on fibers, improving processing efficiency during dyeing and finishing operations . Its emulsifying properties help create stable formulations for textile auxiliaries and finishing agents .
