The creep compliance‐time responses at constant pressure of W/O emulsions containing microcrystalline wax were determined by subjecting them to air pressure in a glass U‐tube and measuring the resultant volume deformations. The constant stress at the tube wall was 2.52 times 10 2 dyn cm ‐2 . Sample slippage along the tube was avoided by blowing protuberances in the wall. Owing to the dynamic nature of the emulsions data reproducibility on a single sample could not be ascertained; with 4.0% gelatine gels reproducibility of the data was very satisfactory.
