The Simplex Centroid Mixture design of the response surface
methodology (RSM) was used to determine the optimum proportions of bleached
palm oil, palm kernel oil and groundnut oil in composite oil that would produce
laundry soap with the optimum cleansing efficiency. Optimization analysis of the
data showed that 0.200, 0.169, and 0.631 proportions of palm oil, palm kernel oil,
and groundnut oil respectively, produced 44.491, 0.149, 2.209, and 7.726 of lather
stability, acid free alkali, chloride and pH respectively at 68.70% desirability.
Based on the results, less of the palm kernel oil should be present in the composite
oil to produce the model soap.
