N2 - A new method for rapid evaluation of emulsion stability has been developed. The technique is based on electrical conductivity measurements during non-destructive short heating-cooling-heating cycles carried out on cosmetic viscous emulsions. The conductivity curve obtained during the second heating cycle is lower and almost parallel to the first curve. The bigger the conductivity difference between the two heating curves, the lower in the stability of the emulsion. A relative stability index, Δ/h, indicating relative change in conductivity between two cycles was elaborated allowing easy comparison of emulsion stabilities having different initial conductivity. The method was compared to standard stability tests with good correlation.
