Abstract

This research was intended to formulate solid bentonite soap using combination of palm oil and
virgin coconut oil used for cleansing najs mughalladzah (extreme najs). Five formula of soap designated with AE
applying bentonite and combination of VCO and PO with different concentrations. The assessment of soap
quality was based on soap hardness, foam stability, water content, total fatty acid, free fatty acid and free alkali.
Evaluation results were analyzed using simplex lattice design (SLD) to obtain optimum formula. Verification of
optimum formula was analyzed using one sample t-test with level of significance of 0.05. The results showed
that optimum concentration of bentonite was 4.06% with percentages of VCO 89.6% and PO of 10.4%. Based on
one sample t-test, there is no significant difference (pH > 0.05) from foam stability and total fatty acid between
the predicted optimum formula as analyzed using SLD and verified result.
