Fig. 1: Physical stability of oil-in-water emulsions.

Emulsions were stored at 5 °C, 25 °C, or 40 °C for up to 12 months and monitored by dynamic light scattering to assess emulsion droplet diameter. Data are represented as means with error bars representing standard deviation of the measurement. a Linear terpenoid SE series, b cyclohexene terpenoid SE series, c ether terpenoid SE series, d MF59-like formulations of selected cyclohexene-containing terpenoids.
