What is the difference between span 80 and Tween 80?
Wikipedia
Sorbitan monooleate (from Span 80)
CAS Number 1338-43-8
Chemical Formula: C24H44O6[2]
HLB Value: 4.3; suitable for water-in-oil (W/O) emulsions. Soluble in warm water and has good dispersibility in organic solvents such as ethanol and ethyl acetate.[3]
Physical Form: Amber liquid[3]
Fatty acid composition: Oleic acid (C18:1) ≤ 60%; balance primarily linoleic (C18:2), linolenic (C18:3) and palmitic (C16:0) acids.
---------------------------
Polysorbate 80 (Tween 80)
CAS Number 9005-65-6 check
Polysorbate 80 is used as an emulsifier in foods. For example, in ice cream, polysorbate is added up to 0.5% (v/v) concentration to make the ice cream smoother and easier to handle, as well as increasing its resistance to melting.

Wikipedia: Hydrophilic-lipophilic balance
Griffin's method for non-ionic surfactants as described in 1954 works as follows:
where is the molecular mass of the hydrophilic portion of the molecule, and M is the molecular mass of the whole molecule, giving a result on a scale of 0 to 20. An HLB value of 0 corresponds to a completely lipophilic/hydrophobic molecule, and a value of 20 corresponds to a completely hydrophilic/lipophobic molecule.
