ABSTRACT


Abstract
The objective of the present study is to understand the influence of sesame seed oil in soap production; This research presents the results of the physicochemical analysis of soaps produced from blends of tallow (animal fat) and Sesamum indicum seed oil. Nine (9) different blends of sesame seed oil and tallow were employed in soap production. The 50:50 blend gave the best soap judging by the TFM (74.5±0.71%), while 90:10 blend gave a better soap than the former in terms of foam ability (64.00±1.41cm3). The saponification values of the oils 187.92 ± 2.01 mg KOH/g (sesame seed oil) and 196.50±3.50 mg KOH/g (tallow), acid values 42.07 ± 1.60 mg KOH/g (sesame seed oil) and 10.69±0.12 mg KOH/g (tallow), iodine value 102.99±5.66 g I2/100g (sesame seed oil) and 42.20±1.35 gI2/100g (tallow).
Keywords: soap, sesamum indicum seed oil, tallow (animal fat), saponification values, acid values and iodine values
