重垢液体洗涤剂——液体洗涤剂的诱惑(英)

Heavy Duty Liquid

介绍了三种形式的液体洗涤剂即：均质型、结构型和无水型。重垢液洗具有洗衣粉所不具备的功能，它在冷水中比洗衣粉易溶，也易分散，不像洗衣粉在贮藏时因为受潮而结块。高浓缩均质液洗生产工艺难，并限制了表面活性剂和助剂的使用范围。结构型液洗，表面活性剂盐析出溶液，形成层状相液滴，最终形成不透明的液体，它非常稳定且可以悬浮大量固体物。无水液洗能包含所有最好的组分而对水的相容性没有影响。尽管近几年液洗有了很大的改变，但目前还在变化中，要抓住机会改变洗涤剂配方。

Three forms of liquid detergent are introduced.That is:isotropic,structured,and nonaqueous.The heavy-duty liquid detergents(HDLs)could do some things powdered detergents could not.HDLs are more soluble in cold water than powder detergents are,more easily dispensed from their packaging,and not subject to the caking that can plague powders when moisture is absorbed during storage.A highly concentrated isotropic liquid may cause difficulties in processing and may restrict the range of usable surfactants and builders.In a structured liquid detergent,surfactants are salted out of solution to form lamellar-phase droplets,the resulting opaque liquid becomes very stable and can suspend high levels of solids.Nonaqueous liquids can include all the best ingredients without causing concerns obout compatibility with water.Although much has changed in liquid laundry detergents over the last few years,more change is on the way ,take the chance to change the detergent formulation.
