Development and Application of Compound Bactericidal Foam Agents
A series of compound bactericidal foam agents have been prepared.Through the selection and optimization of surfactants,the products have excellent foaming properties and the foams are rich and delicate.Using PCMX and ClO2 complex as bactericide,through ratio design and preparation process optimization,the obtained foam agent still has high bactericidal performance at a dilution concentration of 3.3 ‰.The foam properties of the foam agent were measured on the toilet,the bactericidal properties of the foam agent were evaluated by suspension quantitative method,and the stability of the foam agent was evaluated by cold and heat tests.The results showed that the PCMX and ClO2 composite bactericide system could be miscible with the aqueous solution of AES.The composition of the surfactant was simple,but the foam performance was excellent.The measured thickness of the foam layer containing 25 wt%AES on the toilet was greater than 4 cm.When AEO-9 was used as solubilizer,PCMX content was 4.5 wt%,concentration of ClO2 was 150 mg/L,the sterilization rate of diluent was 100%.The foam agent has good stability.After the heat storage,cold storage and freeze-thaw tests,all products have no stratification,no flocculation.And their foaming ability is almost not affected after being placed for 30 days.The sterilization rates of the dilution maintain above 95%.The prepared foam agent has a good application prospect and is suitable for the foam shield of smart toilet to play the functions of splash prevention,odor separation and sterilization.
