Oily vehicles
Maisine® CC is derived from corn oil and has its good taste. It naturally contains antioxidants contributing to greater stability of the excipient and the formulation.

Peceol™ is obtained by direct esterification between glycerol and oelic acid. With a high content in long chain unsaturated fatty acids it is also in favor of lymphatic uptake. An interesting second choice –)
Labrafac™ lipophile WL 1349 is our third choice oily vehicle as it is derived from short chain fatty acids and is more in favor of portal uptake.
Water dispersible surfactants
Due to their composition they enable instant emulsification of the formulation upon contact with water, which is advantageous for example if drops are take with a glass of water.
Both Labrafil® M 1944 CS and Labrafil® M 2125 CS contains long chain fatty acids in favor of lymphatic transport, the former being derived from apricot kernel oil and the second from corn oil.
