Span is a class of nonionic surfactants chemically known as sorbitan fatty acid esters. It is made from sorbitol and fatty acids (such as lauric acid, palmitic acid, stearic acid, oleic acid, etc.) through esterification. Depending on the fatty acid chain, Spectra is divided into various types, such as Spectra 20, 40, 60, 80, etc. The numbers represent the carbon chain length and saturation of fatty acids.
Main Characteristics:
Non-ionic surfactant: non-ionisation in water, high stability, suitable for a wide range of pH environments.
Excellent emulsification performance: able to stabilise oil-water system and form oil-in-water (O/W) or water-in-oil (W/O) emulsion.
Wide range of HLB values: different models of Spectrum have different hydrophilic and lipophilic balance values (HLB values), suitable for a variety of emulsification systems.
Good dispersibility and wettability: widely used in industrial, food, pharmaceutical and cosmetic fields.
Main uses:
Food industry: as emulsifier and stabiliser for ice cream, cream, chocolate and other products.
Cosmetics: used in emulsions, creams, shampoos, etc. to help stabilise oil-water mixtures.
Pharmaceuticals: used as drug excipients in the preparation of emulsions, ointments and injections.
Industrial application: used as lubricant, dispersant and wetting agent for coating, pesticide and other industries.
Common models:
Span 20: Sorbitan monolaurate, high HLB value, strong hydrophilicity.
Disc 40: Sorbitan monopalmitate, medium HLB value.
Disc 60: Sorbitan monostearate, highly lipophilic.
Span 80: Sorbitan monooleate, good flowability, suitable for water-in-oil emulsions.
Summary:
Spiro is a class of multifunctional surfactants with a wide range of applications in food, cosmetic, pharmaceutical and industrial fields due to its excellent emulsifying, stabilising and dispersing properties. Different types of Spiro can be selected according to specific needs to meet the emulsification requirements of different systems.
