磺化合成鲸蜡油/脂肪醇聚氧乙烯醚复合乳液体系的性能研究
China Surfactant Detergent & Cosmetics（2012）
Abstract
以磺化合成鲸蜡油(SSW)为对象,考察脂肪醇聚氧乙烯醚类(AEO)表面活性剂对SSW复合乳液体系的影响,主要研究了SSW/AEO复合表面活性剂的临界胶束浓度(cmc)以及SSW/AEO/CNO/水复合乳液体系的表面张力、动态润湿角、粒度分布和Zeta电位等。结果表明:SSW与AEO复配后cmc增大,其中SSW/AEO9复合表面活性剂的cmc为0.485 g·L-1;复合乳液体系的表面张力降低,润湿能力增强,其中SSW/AEO9/CNO/水复合乳液体系的表面张力为25.05 mN·m-1,平均粒径为72 nm,具有更好的耐酸稳定性。
