Query: Influence of Creaming and Ripening on the Aggregation Rate of Non-Ionic
  Dodecane-in-Water Nanoemulsions   The possible influence of creaming during the measurement of the aggregation
rate of dodecane-in-water nanoemul- sions stabilized with Brij 30 is explored.
For this purpose additional emulsions made with a neutral-buoyancy oil (bro-
mo-dodecane) and mixtures of dodecane and Br-dodecane with squalene were
synthesized. It is concluded that when the effect of ripening is suppressed,
the influence of buoyancy on the evaluation of the flocculation rate is
negligible. In the absence of squalene, ripening is present, and a sizeable
difference in the flocculation rate of dodecane and bro- mo-dodecane is
observed. However, this difference is not caused by the effect of gravity.
