چکیده
عنوان مقاله [English]
Ethoxylated fatty acids or polyoxyethylene esters of fatty acids possess surface active characteristic depending on ethoxylation degree (glycol type used).They have a wide range of applications and are known by formulated trade names.Fatty acids used as starting materials are obtained by the hydrolysis of fats and oils and thus the final products are fully biodegradable.The objective of this investigation is the use of these compounds (lab scale synthesis-mass production) in the preparation of oil-based emulsifier packages with various applications. Considering the necessity of oil solubility of these compounds, the synthetic esters must have the appropriate HLB.On the other hand, by adding the appropriate ethoxylated surface active component, a stable emulsion in hard water needs to be formed in the preparation of emulsifier packages.
