摘要: 合成了胶原基有机硅表面活性剂(CBES),并研究了CBES的表面张力、临界胶束浓度、HLB值、乳化性能以及与非离子表面活性剂异构十三醇聚氧乙烯醚复配后的表面活性和乳化性能。通过吊片法测得CBES可使水的表面张力降低至30.5 mN/m,临界胶束浓度为0.44 g/L;采用乳化法测定CBES的HLB值为14~15,表明CBES为水溶性表面活性剂。此外,CBES乳化大豆油、氨基硅油和聚醚硅油的乳化率分别为10.5%,48.7%和90.0%,且与异构十三醇聚氧乙烯醚复配在乳化效力上具有协同增效作用。

Abstract: The performance of collagen hydrolysate-based silicone surfactant (CBES) was determined through the measurement of surface tension,critical micellization concentration,hydrophilic-lipophilic balance (HLB) and emulsifying performance.The surface activity and emulsifying performance of the blend system of CBES with iso-tridecanol ethoxylates nonionic surfactant were further determined.Results showed that CBES can decrease the surface tension of water to 30.5 mN/m and critical micelle concentration is 0.44 g/L by Wilhelmy method.HLB is 14~15 determined by emulsification method,indicating that it is a water soluble surfactant.In addition,the emulsification ratio of CBES emulsifying soybean oil,amino silicone oil and polyether silicone oil is 10.5%,48.7% and 90.0%,respectively.There is synergistic effect for emulsifying efficacy between CBES and iso-tridecanol ethoxylates.

Key words: silicone surfactant, collagen, surface tension, emulsifying performance
