Palm oil-based polymeric surfactants of anionic and non-ionic charges, AS1 and NS1, were successfully synthesized via polyesterification reaction. Both AS1 and NS1 demonstrated limited solubility in aqueous medium. Surfactant solutions were prepared before adding into the partially de-ammoniated HA latex. The efficiency of these surfactants as latex stabilizers was evaluated in a 2-week short-term-stability study. AS1 showed greater potential in stabilizing the partially de-ammoniated HA latex compared to NS1. Further study was conducted to investigate the minimum amount of AS1 needed for stabilizing latex concentrate up to 6-month long-term storage. AS1 of 0.6 wt% showed higher latex stabilization ability by maintaining VFA no. < 0.035, MST at 1800s, alkalinity ≤ 0.2, pH at 11, viscosity < 70 cps and particle size < 0.7 μm for up to 6-month storage. It was postulated that AS1 could induce both steric and electrostatic stabilization mechanisms to stabilize latex particles in its aqueous medium. These results provide a useful reference to understand the performance of non-cytotoxic palm-based surfactant in latex stabilization system.

通过聚酯化反应成功合成了具有阴离子和非离子电荷的棕榈油基聚合物表面活性剂AS1和NS1。AS1 和 NS1 在水性介质中的溶解度有限。在加入部分脱氨的 HA 胶乳之前制备表面活性剂溶液。在为期 2 周的短期稳定性研究中评估了这些表面活性剂作为乳胶稳定剂的效率。与 NS1 相比，AS1 在稳定部分脱氨的 HA 乳胶方面表现出更大的潜力。进行了进一步研究以调查稳定乳胶浓缩物长达 6 个月的长期储存所需的最小 AS1 量。0.6 重量％的 AS1 通过保持 VFA 没有显示出更高的胶乳稳定能力。< 0.035，MST 在 1800 秒，碱度 ≤ 0.2，pH 值为 11，粘度 < 70 cps 和粒度 < 0。7 μm 最多可存放 6 个月。据推测，AS1 可以诱导空间和静电稳定机制，以稳定其水性介质中的乳胶颗粒。这些结果为了解非细胞毒性棕榈基表面活性剂在乳胶稳定体系中的性能提供了有用的参考。
