El aceite de pescado argentino y sus posibilidades de utilización en procesos industriales. Parte II. Obtención de derivados sulfatados para la nutrición de cueros

Abstract

Twelve sulfated oils were prepared from Argentine's raw fish oils, and three more from samples previously bleached. The samples were taken montly during a year at a factory in the Mar del Plata (Argentine) zone. Each oil and its sulfated derivative was analyzed in its physico-chemical properties. The hydrophilic and hydrophobic fractions were separated and the fatty acids composition of the latter were determined. From the results obtained, it is possible to conclude that the Argentine's fish oils sulfated will be able to be used in fat-liquoring of leather.
