Emulsifying agents linoleic acid

Lipids also can be beneficial for cells in culture, since some substances absorbed by the cells need to be solubilized in lipids, or in some cases the toxicity of compounds may be reduced by complexation with lipids. The absence of essential lipids such as linoleic acid, lecithin, cholesterol, ethanolamine, or phosphorylcholine can result in the decrease of cloning efficiency and in reduction in the size of colonies, as shown for insect cells by Echalier (1997). However, one of the difficulties in supplying lipids at reasonable concentrations is their low solubility. To circumvent this limitation, lipids can be emulsified with complexing agents such as Pluronic F68 or cyclodextrin (Maiorella et al., 1998). 

Linoleic acid is used in topical transdermal formulations, in oral formulations as an absorption enhancer, and in topical cosmetic formulations as an emulsifying agent. It is also administered in parenteral emulsions as a dietary supplement. 

Ammonium soaps n. Soaps formed by reaction of ammonia with the higher molecular weight fatty acids, such as ammonium ole-ate, linoleate, stearate, etc., used as wetting or emulsifying agents.

Industrially produced lard is rendered from a mixture of high and low quality fat sources from throughout the pig. It is typically hydrogenated, and often treated with bleaching and deodorizing agents, emulsifiers, and antioxidants. Such treatments make the lard shelf stable. The available quantities of lard are about 6 million tonnes a year. The fat contains palmitic (20%-32%), stearic (5%-24%), oleic (35%-62%), and linoleic (3%-16%) acids as major components. It is unusual in that 70% of the palmitic acid is in the sn-2 position. It also contains cholesterol (0.37%-0.42%). ...
