- 33. Conclusion - From the extraction of oil in pumpkin seeds oil, the oil content is about 30.6 % - From the experiments, the formula 10 has the most foam capacity in compare with all the liquid soap and the formula 9 has the most foam capacity in compare with 9 formulas produced liquid soap. - The formula 5, 11, 12 has the most ability to emulsify paraffin oil. As the paraffin oil is lipid with composed in dirt.
- 34. Conclusion - From the experiment of measuring pH value, the formula 7 has the least pH value in compare with 9 formulas produced liquid soap, which is 9.73. - From the measuring of satisfactions value of using liquid soap, the formula 7 , 8 and 9 satisfied the samples respectively.
