Emulsified Fatty Acids and Antimicrobial Activity

Stable aqueous emulsions were prepared consisting of vegetable oils and fatty acids, nonionic surfactants and deionized water, and prehomogenized with the Fisher Sonic Dismembrator and completed with the Silverson Flomogenizer (emulsifier turbine). 

Three fatty acids comprise an oil and are usually referred to as just acids. Caprylic acid (octanoic acid or 1-heptanecarboxylic acid) is the most antimicrobial emulsified fatty acid compared to capric and oleic (higher in molecular weight compared to caprylic acid). Oleic acid (d.v-9-octadcccnoic) and caprylic acid are natural fatty acids found in vegetable and marine oils. The oleic acid or similar low 

Any factor that stabilizes the anion more than it stabilizes the acid should increase the acidity any factor that makes the anion less stable should decrease acidity. The chain of CH2 groups and single CH3 group donates electrons and make
