| advantage | soap powder has the characteristics of natural, strong decontamination, ultra-low foam, easy rinsing, etc. Its active substances are mainly fatty acids, and more than 90% of the raw materials come from renewable vegetable oils and fats, and do not contain polyphosphate. Soap powder has low irritation to the skin and protects the fabric. The washed clothes are fluffy and soft without using softener, thus solving the problems of dirt accumulation, hardening and static electricity of the fabric after repeated washing. Because the special calcium soap dispersant is added to the soap powder, the detergency is stronger, which is 1.3 to 1.5 times that of ordinary washing powder; it does not require water like soap, even in low temperature and high hardness water It still shows excellent washing performance. |
| preparation | 1, using 500g of waste oil, 200g of purified water, 71g of caustic soda, 100g of refined salt and 750g of hot water as raw materials, it is prepared by salting-out method. First mix the caustic soda with purified water and cool it slightly. 2. Heat the waste grease to about 80°C. When the temperature of the caustic soda solution and the grease are the same, mix and stir them. 3. During the stirring process, the soap will begin to change while heating and continuously stirring. Stirring at a high temperature of about 80°C allows the soap to undergo a rapid saponification reaction. 4. When stirring to become a grain with a little transparent soap particles, you can stop stirring, but the temperature cannot change. 5. Dissolve the refined salt with 750g of boiled water prepared in advance, and then add the hot brine to the soap particles just prepared. 6. After the brine is mixed in, while continuing to heat to maintain the previous high temperature, while stirring well, you will find that soap and water begin to separate. Salting out will separate glycerin, pigment, protein and other impurities in soap, and can obtain soap with high purity. 7, keep turning and stirring, let the salt water and soap better mix evenly into every corner of the soap. Stir for about ten minutes, then set them aside to cool naturally. Note that the action should be light when stirring to avoid splashing out of hot water. 8. Let the mixed solution stand overnight. It can be seen that soap will float on the upper layer, and the lower layer is salt water mixed with impurities such as glycerin. 9. Take out the soap on the upper layer, dry it, and break it with a crusher to make soap powder, which can also be used directly. |
