Emulsification and its Applications in Cosmetic Industry() Macroemulsion Instability and Main Factors Determining Stability

（上接１９９９年第２期第５３页）２．２聚结静电势垒的存在［４，５，９，１０］根据乳化剂是否带电荷（如使用离子型乳化剂），对絮凝作用的处理方法是不同的，可利用胶体稳定性的ＤＬＶＯ理论进行定量计算。ＤＬＶＯ理论是在１９４０年由四位学者（Ｄｅｒｊａｇｕｉｎ...

Macroemulsions are thermodynamically instable systems.The part of this paper describes various phenomenon of macroemulsion instability,including creaming,flocculation,coalescence,breakdown,phase inversion and Ostwald ripening.Main factors determining stability are discussed in detail,for example,physical nature of interfacial film,electrical and steric barrier to coalescence,and stabilization by solid particles etc.
