Caproate micelle

Fig. 37. With a caproate micelle the layer of water between the polar groups will be much less thick than with an oleate micelle because the oleate micelle is much more flattened.

Fig. 35. With solutions of Na caproate the short spacing will eventually also be observable, in other words, flattened micelles are produced.

The caproate behaves at low concentrations in a manner exactly comparable to the valerate (Fig. 35 a, b, c). Obviously in this case the flattening of the micelle at the high concentrations goes somewhat further (Fig. 35d), as a result of which a short spacing, namely the cross section of the paraffin chains (4.6 A) becomes visible.
