Which is better Tween 20 or Tween 80?
Tween-80 (polyoxyethylene sorbitan monooleate) is oleate and Tween-20 (polyoxyethylene sorbitan monolaurate) is laurate. Tween 80 has a longer aliphatic tail and therefore more lipophilic. Tween 20 is the more hydrophilic.
How do you calculate the HLB value of a mixture?
Using the following equation: HLB desired = ( % surfactant A ) × ( HLB Surfactant A ) + ( % surfactant B ) × ( HLB Surfactant B . ) A blend of surfactant A, HLB = 7.8, and surfactant B, HLB = 13.4 produces a combination that is water soluble and contributes other desired properties.
How is HLB number calculated?
What is the HLB value of Tween 80?
What is the HLB value of Tween 80? Commercial Name Chemical Name HLB Value Tween 60 Polyoxyethylene sorbitan monostearate 14.9 Tween 61 Polyoxyethylene sorbitan monostearate 9.6 Tween 65 Polyoxyethylene sorbitan tristearate 10.5 Tween 80 Polyoxyethylene sorbitan monooleate 15.0
What is the difference between Tween 80 and Tween 20?
TWEEN 80 is a polyethylene sorbitol ester, also know as Polysorbate 80, PEG (80) sorbitan monooleate, polyoxyethylenesorbitan monooleate. TWEEN 20 is a polyoxyethylene sorbitol esteris, a frequently used member of the polysorbate family.
How do you find the HLB of a blend?
By drawing a perpendicular line through the intersection of your two previous lines, you can read off the percentage of TWEEN you need, at the top or bottom of the graph. You can enter the HLB values of any emulsifiers you wish along the left and right margins to compute HLB of any desired blend.
What is the difference between HLB 12 and HLB 11?
At 4% concentration, the emulsifier having HLB 12 produces stable emulsions of your ingredients, and greater concen- trations produce no greater stability. By contrast, the emulsifier having HLB 11 might require a concentration of 8% to produce emulsions of equal or less stability than the other emulsifier.
