The oil was extracted from raw materials such as sheep’s tail fat (TF), outer fat (OF), and inner fat (IF), which were analyzed by chemical methods, and the liquid soap was obtained by cold methods. Liquid soap was prepared from three types of raw materials, each of which was mixed with 70% fat oil and 30% liquid oil. The ratio was chosen to dilute the liquid soap to 2% of the product. The most suitable oil for preparing liquid soaps from raw materials such as TFO, OFO, and IFO was the tail fat oil (TFO). The highest unsaturated fatty acid content in crude fats and oils was 41.23%, the highest content of saturated fatty acids was 22.3%, and the highest content of methyl-stearate was 33.65% by the GC-MS analytical method.展开更多

However, soap-based product appears to be not physically stable under certain circumstance. For example, product viscosity decreases with the increase of temperature but goes up when the temperature goes down. More seriously, phase separation may occur for some products with time. Many efforts have been made to improve the stability of soap-based formulations mainly focusing on 1) adjust the fatty acids ratio;2) optimize saponification level;3) addition of thickeners and surfactants. Improvements have been made upon recent reports. However, required stability of the formulations at both high and low temperature is not satisfied yet. In this work, we introduced one type of non-ionic emulsifier to the soap-based formulation, through which to regulate the microstructure. It is seen that the stability is significantly improved at both high and low temperature, and the using performance is enhanced in the meantime.展开更多
