Abstract A study of the interaction between a model skin surface lipid (SSL) and an oil base skin softener (G2) was made by comparing the phase behavior of these substances in combination with the water/triethanolamine: oleic acid (1:1 wt ratio) system. A principle feature of the water/G2/triethanolamine:oleic acid (TEA:OL) system was the formation of a lamellar liquid crystal region that incorporated an average of 40% G2 over the 10–45% water range. The phase behavior of the water/SSL/TEA:OL system demonstrated only over a 4–9% water range. At greater than 5% SSL, there is the complete absence of single phase regions above 10’% water. From comparison of the phase regions and the small angle X‐ray diffraction results, it is found that for G2/SSL mixtures the phase behavior of the lamellar liquid crystal is dominated by the SSL and the interlayer spacing of the lamellar liquid crystal is dominated by G2.
