Span 20 is a 100% bio-based, non-ionic surfactant, easy to handle, for use as a versatile co-emulsifier for W/O and O/W emulsions, pigment dispersant and carrier liquid. The surfactant can be used for particle morphology control in S-PVC. The main application is in decorative coatings.
What is the difference between span 20 and span 80?
Since Span 80 is more hydrophobic (HLB = 4.3) than Span 20 (HLB = 8.6), it produced two phases of proniosomal liquids at cholesterol concentrations below 30%. The formed proniosomal gels were found to be thermo-reversible.
Is span 20 soluble in water?
Span 20 Properties Practically insoluble, but dispersible in water, miscible with alcohol. Soluble in 2-ethoxyethanol, ethanol and methanol.
What is sorbitan laurate?
Sorbitan Laurate is a monoester of lauric acid and hexitol anhydrides derived from sorbitol.
What's the difference between polysorbate 20 and 80?
From the molecule, the only difference between polysorbate 20 and 80 is the fatty acid attached to the polyoxyethylene sorbitan part of the molecule, lauric acid in 20 while oleic acid in 80.Apr 23, 2020
What is the difference between Tween 20 and 80?
One common question regarding the Tween family detergents is the difference between Tween 20 and Tween 80, the two most commonly used members. Tween 20 has lauric acid, while Tween 80 has oleic acid (Figure 3).
What is the difference between Span 80 and Tween 80?
Span 80 has an HLB value of 4.3, which falls within the usual range of HLB 4–6 for water-in-oil (W/O) emulsifiers. Tween 80 has an HLB value of 15, within the range of HLB 8–18 for oil-in-water (O/W) emulsifiers.
