Abstract
Mucilage palm oil (M.P.O.) was obtained from physical refining step for cru de palm oil. The components of M.P.O. were high content of free fatty acids (82.2%) with simple amount of neutral oil (11.9%), while the residual cont ent (unsaponifiable matter and impurities) was 2.1% and in addition to 3.8% water. The results indicated that the colours of M.P.O., tallow and palm k ernel dd improved after bleaching. Eight soap samples (n.(os) 1-8) were pre pared from bleached fatty blends of mucilage palm oil, tallow and palm kern el oil at different ratios. The results showed that the moisture contents o r soap samples n.(os) 2, 7 and 8 were high compared with the standard soap (sample n.(o) 1), subsequently their total fatty matters became tower than that found in the control soap (sample n.(o) 1). The findings marked that t he unsaponifiable matter of soaps n.(os) 2, 7 and 8 were higher compared wi th the other soaps. No high differences were observed in the free alkali of all soaps (range from 0.06 to 0.09%). On the other hand. high differences were found in the free oil of all soap samples (n.(os) 2-8) compared with t he standard soap (sample n.(o) 1), except soap samples n.(os) 2, 7 and 8, w hich record very high. The best soap samples in the colour were in the foll owing increasing order: n.(os) 1 > 3 > 4 > 5 > 6 > 7 > 8 > 2, respectively. The results showed that the better soap samples in the physical properties were in the following increasing order: soap n.(o) 3 > soap n.(o) 4 > soap n.(o) 5 > soap n.(o) 6 compared with the standard soap (sample n.(o) 1), w here from firm structure with high foam, while the other soap samples (n.(o s) 2, 7 and 8) were poor quality (i.e., low lathering properties with deep colours). Therefore, it could be concluded that mucilage palm oil can be used as a ne w fatty material for toilet soap manufacturing at ratio of 40% from the fat ty blend.
