Abstract:

Through the tests of water solubility, freezing point, wetting, emulsification, decontamination and foam properties, the performance of the binary blend system of non-ionic surfactant modified SOE-N-60 with peregal O-25 and peregal O-20 respectively were estimated. The results show that the binary compound system of SOE-N-60 with a total mass fraction of 70% and peregal at 25 ℃ is uniform and transparent and the freezing points of the products are all below 10 ℃, when the mass ratio of SOE-N-60 to peregal O-25 is greater than 5:5 and the mass ratio of SOE-N-60 to peregal O-20 is greater than 4:6. The decontamination performance and liquid paraffin emulsifying performance of the compound products exhibit a certain synergistic effect. The foaming properties of the compound products are slightly higher than the single SOE-N-60. Therefore, the compound products are suitable for the development of low temperature and low foam concentrated liquid detergent.
