Fatty Component

From soapstock, which is a waste product of sunflower oil production, the fatty component was isolated using isopropyl alcohol, toluene, fusel oil and a mixture of common salt and nonionic surfactants. With the help of the Langmuir film balance the molecular areas of isolated fats were found and the degree of hydrophobization in comparison with the original soapstock was evaluated. It was found that the strongest compression of the monolayer is observed when using fusel oil. The surface active properties of emulsifiers, synthesized by alkaline hydrolysis method on the basis of the obtained fat extracts and original soapstock, were studied. These results are consistent with measurements on the Langmuir balance.

And Performance

Imidazoline surfactants belong to the category of cationic surfactants. Cationic surfactants are often quaternary nitrogen salts and are widely used both in nonaqueous systems and in applications such as textile softeners, dispersants, and emulsifiers. This study describes the surface-active properties of cationic imidazolinium surfactants synthesized from different fatty acids. Their laundry performance in combination with nonionic surfactants like detergency, foaming property, softening property, rewettability etc., is also emphasized.
