SOLID PARTICLES OF PARAFFIN AND STEARIC ACID STABILIZED BY SPAN 80 AND TWEEN 80
In this paper paraffin and stearic acid particles obtained by temperature phase-inversion method and stabilized by mixture of surfactant: sorbitan monooleate Span 80 and polyethylene glycol sorbitan monooleate Tween 80 were investigated. The average size of paraffin particles decreased from 110 to 40 nm in the range of total Span 80/Tween 80 concentrations of 5 - 12.5 vol.%. The sizes of stearic acid particles decreased from 160 to 50 nm in the range of total surfactant concentrations of 5 - 12.5 vol %.
