Product Description

 

Span 80, also known as sorbitan monooleate, is a widely used nonionic surfactant that belongs to the family of sorbitan esters. Here's an introduction to Span 80:

Chemical Structure: Span 80 is derived from the esterification of sorbitol with oleic acid. It consists of a hydrophilic polyol (sorbitol) head group and a lipophilic oleic acid tail.

Properties:

• Physical State: Span 80 is typically a yellowish to brownish viscous liquid or semi-solid at room temperature.
• Solubility: It is insoluble in water but soluble in organic solvents such as ethanol, ether, and chloroform.
• Emulsifying Properties: Span 80 acts as an excellent emulsifier, facilitating the formation and stabilization of oil-in-water (O/W) emulsions. It lowers the interfacial tension between immiscible phases, allowing them to mix homogeneously.
• Surface Activity: Span 80 reduces the surface tension of liquids, enhancing wetting and spreading properties. It is often used as a wetting agent in various applications.
• Stability: Span 80 provides emulsions with good stability against phase separation, coalescence, and creaming over time.

Applications:

• Food Industry: Span 80 is used as an emulsifier and stabilizer in food products such as margarine, salad dressings, ice cream, and baked goods. It helps to improve texture, mouthfeel, and shelf life.
• Pharmaceuticals: It is employed in pharmaceutical formulations for emulsification of oils in creams, lotions, and ointments, as well as in oral and topical medications.
• Cosmetics: Span 80 is utilized in cosmetic products including creams, lotions, makeup, and hair care products as an emulsifier, surfactant, and solubilizer.
• Textiles: It is applied in textile processing for emulsifying and lubricating fibers during spinning and weaving processes.
• Personal Care Products: Span 80 is found in various personal care items such as soaps, shampoos, conditioners, and body washes to enhance their stability and performance.
• Industrial Applications: It is used in industrial processes including metalworking fluids, paints, coatings, and adhesives as an emulsifying agent and dispersant.

Safety Considerations: Span 80 is generally regarded as safe for use in food, pharmaceutical, and cosmetic products when used according to regulatory guidelines. However, proper handling and storage procedures should be followed to minimize the risk of exposure.

In summary, Span 80 is a versatile nonionic surfactant with emulsifying, stabilizing, and surface-active properties, making it valuable in a wide range of applications across various industries.
