Polysorbate 80 (Tween 80) is a non-ionic surfactant and emulsifier (w+x+y+z=19). A typical application is in ice cream, where it hinders the milk proteins from completely coating the fat droplets. This allows for a firmer texture, which is associated with high quality ice cream. Which of the following statements is true? I) Polysorbate 80 is an ester.
II) Polysorbate 80 has a hydrophilic component.
III) Polysorbate 80 has a hydrophobic component.
IV) Polysorbate 80 forms micelles above its critical micellar concentration.
