Choline carboxylates, ChCm, with m = 2-10 and choline oleate are known as biocompatible substances, yet their influence on biol. membranes is not well-known, and the effect on human skin has not previously been investigated. The short chain choline carboxylates ChCm with m = 2, 4, 6 act as hydrotropes, solubilizing hydrophobic compds. in aq. soln., while the longer chain choline carboxylates ChCm with m = 8, 10 and oleate are able to form micelles.In the present study, the cytotoxicity of choline carboxylates was tested using HeLa and SK-MEL-28 cells. The influence of these substances on liposomes prepd. from dipalmitoylphosphatidylcholine (DPPC) was also evaluated to provide insights on membrane interactions. It was obsd. that the choline carboxylates with a chain length of m > 8 distinctly influence the bilayer, while the shorter ones had minimal interaction with the liposomes.
