Abstract :Local black soap, produced from coconut oil and plantain peel biochar insert ignore into journalissuearticles values(alkaline source); was presented in this study since the agricultural raw materials gain significance in environmentally benign feedstocks for saponification reactions. The physicochemical analysis of the coconut oil and plantain peel biochar shows remarkable free fatty acid insert ignore into journalissuearticles values(FFA); and alkalinity contents respectively suitable for soap making. The physicochemical properties of the as-prepared local black soap demonstrated a good moisture content insert ignore into journalissuearticles values(15.1 %); showing that it can be stored for long periods without any water-associated deteriorations. The percentage of matter insoluble in water insert ignore into journalissuearticles values(4.4 %);, matter insoluble in alcohol insert ignore into journalissuearticles values(12.3 %);, FFA content insert ignore into journalissuearticles values(2.1 %);, and pH insert ignore into journalissuearticles values(9); were found to be higher than the acceptable limit according to the Nigerian Industry Standards insert ignore into journalissuearticles values(NIS);. Also, the total fatty matter insert ignore into journalissuearticles values(TFM); was higher insert ignore into journalissuearticles values(67.6 %); than the minimum acceptable level with a good foam height of 2.5 cm. The overall results show good soap properties and are suitable for domestic purposes.
