Abstract
ABSTRACTStabilization mechanism of salt, as a dissolved electrolyte, in oil‐in‐water emulsions in the presence of stabilizers and/or emulsifiers, propylene glycol alginate, xanthan gum and/or polysorbate‐60 has been studied using rheological techniques, particle size analysis and surface tension measurements. Salt affected the stability of the ternary system, propylene glycol alginate/xanthan gum/polysorbate‐60, depending on the emulsifier/stabilizer ratio. Creep measurements indicated that low salt concentrations were particularly effective when PGA:X ratios were used in the presence of PS‐60. In both PGA:X and PGA:X/PS‐60 systems salt did not affect the particle size distribution during aging. Surface tension measurements were in agreement both with particle size distribution and high shear rate experiments.
