Technical Field
The invention relates to the technical field of daily chemical products, in particular to a nonionic surfactant and a cleaning agent.
Background
At the in-process of wasing the kitchen, a lot of people can feel very vexed, because produce a large amount of greasy dirt when culinary art food, through high temperature oxidation attach at kitchen ceramic tile, on various electrical apparatus in kitchen such as gas-cooker and smoke ventilator electromagnetism stove, not only difficult washing just breed the bacterium in a large number easily, produce the peculiar smell, so can select better product, not only let the washing become easier more, can also prolong the life of the various products in the kitchen.
For heavy oil polluted areas such as kitchens, there are currently roughly three cleaning methods, (1) strong alkaline type, which has strong decontamination capability but also strong corrosivity, and the type is basically eliminated. (2) The solvent type uses the good oil stain solubility of the solvent to achieve the decontamination effect, but has the defects of flammability, explosiveness and toxicity. (3) The surfactant is the most widely studied detergent, and has mild operation, low cost, weak emulsifying capacity and incomplete cleaning.
