Abstract :Local black soap, produced from coconut oil and plantain peel biochar (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 (FFA) and alkalinity contents respectively suitable for soap making. The physicochemical properties of the as-prepared local black soap demonstrated a good moisture content (15.1 %) showing that it can be stored for long periods without any water-associated deteriorations. The percentage of matter insoluble in water (4.4 %), matter insoluble in alcohol (12.3 %), FFA content (2.1 %), and pH (9) were found to be higher than the acceptable limit according to the Nigerian Industry Standards (NIS). Also, the total fatty matter (TFM) was higher (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.Keywords : Local black soap, plantain peel, coconut oil, Agricultural feedstocks
