 Abstract:

The study attempts the synthesis of green detergent from soya bean (Glycine max) oil. The objective of the study was to produce phosphate free green detergent from soyabean oil, and to produce detergent which is environment friendly and more biodegradable than the synthetic detergents. Soya bean seeds were dried in the sun until the casting split and further dried in the oven to reduce the moisture content. The oil, Soxhlet was extracted from the soya bean seed using n-hexane. The soya bean oil was alkali refined and then boiled with lemon peels for clarification. The refined oil was separated using a separating funnel. Further procedures for detergent production were carried out. Green detergent was created by combining concentrated sulphuric acid, sodium hydroxide, and hydrogen peroxide. The green detergent's properties, such as pH and foamability, were tested and compared to those of a local detergent as a control. The moisture content and oil content were calculated on a dry matter basis as 6.92% and 36.8%, respectively. The saponification value of the oil was found to be 158.48meq/kg with a golden color, a pleasant smell, and a viscous nature. The efficiency of the liquid detergent produced from soya bean oil was not satisfactory. Synthetic liquid detergent, but continued use of synthetic detergents can cause an increase in phosphate in rivers and water bodies, which leads to eutrophication and the death of fish. As an alternative, detergent can be produced from natural vegetable oils like soya bean oil and used as a solution to the problem.
