Abstract:

Ease of formation and stability of oil (D-limonene) in water emulsions were studied and detd. by measuring the spectral adsorption of dild. emulsions at 2 wavelengths (800 nm and 400 nm). Stability indexes were derived from measurements carried out 24 h after prepn. at room temp. and after an addnl. 8 h of incubation at 75°. Various factors affecting emulsion stability, such as type of emulsifier and required HLB, oil concn., and amt. of emulsifier and the method of prepn. were tested by using this method.
