I just did some tests:
DMSO, ethanol, propylene glycol, and water are all mixible at all ratios in each other. octyl salicylate is as soluble in ethanol as sugar is in water. Although large amounts of oleic acid are not mixible in smaller amounts of water, a little oleic acid in ethanol dissolved the octyl salicylate.
