Soaps are the oldest and perhaps most natural surfactants. Carotenoic acids and –salts have outstanding qualities by combining visibility and traceability with biological activity. Revisiting previously synthesized glycol-, glycerol- and phospholipids with carotenoic acids.īased on the presented results (alkalicarotenoates have similar surface properties to alkalicarboxylates, carotenoic acids react like carboxylic acids to lipids), we argue for inclusion of conjugated carotenoic acids in fatty acid inventories and organic chemistry textbooks. Ĭomparing these data with Na-, K- and Cs-carboxylates,.Presenting new data on surface tension and critical micelle concentration of Na-, K- and Cs-carotenoates, We endeavor to extricate conjugated polyenoic acids from oblivion by However, colored conjugated polyunsaturated fatty acids do exist, occurring abundantly in nature or manufactured at large scale. The prevalence of colorless fats and unadulterated white soaps has ensured that fatty acids are not associated with color. Fatty acids in edible fats or in cleaning soaps have one thing in common: they are colorless.
In contrast, the term “fatty acid” gives no hint of being associated with “soap” (Na and K salts of fatty acids). The term “fatty acids” is conceptually well defined with regard to fats, whose extent of saturation or unsaturation is precisely indicated in the content description of foodstuff.
