Spread monolayers of two new skin permeation enhancers, MacroDerm A and MacroDerm L were investigated at the water/air interface as a function of temperature and of subphase composition. Both components did not seem to be markedly affected by changes in ionic strength and by the presence of metal ions in the subphase. The two-dimensional binary system MacroDerm A - MacroDerm L was also studied at the water/air interface at 298 K on pure water subphase. The behavior of surface areas, surface compressional moduli and collapse pressure as a function of molar ratios of components shows that MacroDerm A and MacroDerm L are miscible.

Abstract

Spread monolayers of two new skin permeation enhancers, MacroDerm A and MacroDerm L were investigated at the water/air interface as a function of temperature and of subphase composition. Both components did not seem to be markedly affected by changes in ionic strength and by the presence of metal ions in the subphase. The two-dimensional binary system MacroDerm A - MacroDerm L was also studied at the water/air interface at 298 K on pure water subphase. The behavior of surface areas, surface compressional moduli and collapse pressure as a function of molar ratios of components shows that MacroDerm A and MacroDerm L are miscible.
