In some soap stabilized liquid paraffin emulsions a correlation has been found between emulsion type and the contact angle of the soap gel (the stabilizing agent) at the o/w interface. Two unrelated series of emulsions have been prepared, one series being stabilized by magnesium oleate gels and the other series by ammonium oleate gels. The soap gels were prepared by double decomposition and suppression of ionization respectively. Unlike the magnesium oleate system no inversion to w/o emulsions occurred with the ammonium oleate series. This dissimilarity is predicted from differences in the contact angles of the soap gels at the o/w interface.
在一些用肥皂稳定的液体石蜡乳液中，已发现乳液类型与肥皂凝胶（稳定剂）在油/水界面的接触角之间存在相关性。制备了两个不相关的乳液系列，一个系列由油酸镁凝胶稳定，另一个系列由油酸铵凝胶稳定。肥皂凝胶分别通过复分解和抑制电离制备。与油酸镁体系不同，油酸铵系列未发生向水包油乳液的转变。这种差异可从肥皂凝胶在油/水界面的接触角差异预测得出。
