Cocamidopropyl betaine is a coconut oil-based surfactant that is widely used in cosmetics and personal care products due to its milder and less irritating properties compared to conventional petroleum-based surfactants. Palm kernel oil can be used for the synthesis of betaine (palm kernel amidopropyl betaine), following the same route as for the synthesis with coconut oil via two reaction steps. However, there was little information on the optimal operating conditions for each process. The method for the production of betaine and its operating conditions were studied in order to obtain a compatible betaine product with better properties than those of the commercial product. The studied method and operating conditions allowed the production of low viscosity betaine with a higher surfactant content (31.55 wt%) than that of the commercial betaine products (25.10 wt%). In addition, other feedstocks such as coconut oil, split palm kernel oil and coconut oil-based fatty acid methyl ester were used in this study to produce betaine from low-cost production.

工艺变量对棕榈仁酰胺丙基甜菜碱生产的影响研究

椰油酰胺丙基甜菜碱是一种椰子油基表面活性剂，与传统的石油基表面活性剂相比，其性质更温和、刺激性更小，因此广泛用于化妆品和个人护理产品。棕榈仁油可用于合成甜菜碱（棕榈仁酰胺丙基甜菜碱），其路线与椰子油合成相同，经过两个反应步骤。然而，关于每个过程的最佳操作条件的信息很少。对甜菜碱的生产方法及其操作条件进行了研究，以获得性能优于市售产品的相容性甜菜碱产品。研究的方法和操作条件允许生产具有较高表面活性剂含量的低粘度甜菜碱（31. 55 wt%）比商业甜菜碱产品（25.10 wt%）高。此外，本研究还使用其他原料，如椰子油、裂开棕榈仁油和椰子油基脂肪酸甲酯，以低成本生产甜菜碱。
