Abstract
used cooking oil can be used as base substance To manufactured of
transparent solid soap. This aims of this reseach,,was determine effict of the
addition stearic acid and glycerin with various concentrations of the quality of
transparent solid ,soap and determine the best formulation of transparent solid
soap. This research conducted in the Laboratory Processing and Analysis-of
Agticuttural Technology, Faculty of Agriculture, University of Riau. This
research carried out an experimantelly using a completely randomized design
(RAlL) with 8 treatments and 3 repetition. Data quality of product was analyzed
statistically variance. If it shows F-hit greater than F-tab then do Tukey test. Whereas
organoleptic test carried out in non-parametric. If it shows F hit greater than F tab
then do Friedman test at level 5 %. The results showed that the addition of stearic
acid and glycerin provide effect to the water content, ALB, and pH. Based on
the results of the research best formulation of transparent solid soap is AG6
(stearic acid 12%, glycerin t 11%) with 3,09% water content,. ALB not detected, the
volume of foam144.244cm, pH 10.5, no cause iritation and the result
organoleptic test panelist for colour, flavor, texture and foam showed preference.
