Hemiesters and Hemiamides of maleic and succinic acid viz. sodium lauryl succinate (C₁₂SE), sodium lauryl maleate (C₁₂ME), sodium lauryl succinamide (C₁₂SA), sodium lauryl maleamide (C₁₂MA), sodium hexadecyl succinate (C₁₆SE) and sodium hexadecyl maleate (C₁₆ME) were synthesized and investigated as surfactants in the pure water and aqueous hydrotrope [sodium p-toluene sulfonate (NaPTs)] solution. The chemical structures of the prepared surfactants were established by FTIR and ¹H NMR spectroscopy. The surface tension measurements depicted low CMC and a high adsorption efficiency (pC₂₀) which is highly beneficial for creating personal care formulations. The dynamic light scattering (DLS) technique indicated the formation of larger micelles which was important for skin care as larger micelles cannot penetrate the skin layer. Moreover, these surfactants depicted good foamability and stability attributed to faster monomer adsorption and small bubble size which was preferred for cleansing application. Additionally, low protein/lipid solubilization by these surfactants indicated its mild behaviour on skin as compared to other commonly used conventional anionic [sodium lauryl sulfate (SLS)], zwitterionic [cocamidopropyl betaine (CAPB)] and nonionic [decyl glucoside (DG)] surfactants. Viscosity measurements suggested decent thickening ability of surfactants in the presence of co-surfactant like lauramine oxide. Basis of all the properties discussed, these novel hemiesters and hemiamides seem promising as surfactants for improving various characteristics in potential personal care formulations.

马来酸和琥珀酸的半酯和半酰胺即。十二烷基琥珀酸钠 (C ₁₂ SE)、十二烷基马来酸钠 (C ₁₂ ME)、十二烷基琥珀酰胺钠 (C ₁₂ SA)、十二烷基马来酰胺钠 (C ₁₂ MA)、十六烷基琥珀酸钠 (C ₁₆ SE) 和十六烷基马来酸钠 (C ₁₆ ME) 作为表面活性剂在纯水和水溶助长剂 [对甲苯磺酸钠 (NaPTs)] 溶液中被合成和研究。通过FTIR和¹ H NMR光谱确定了制备的表面活性剂的化学结构。表面张力测量显示低 CMC 和高吸附效率 (p C₂₀) 这对创建个人护理配方非常有益。动态光散射 (DLS) 技术表明形成较大的胶束，这对于皮肤护理很重要，因为较大的胶束不能穿透皮肤层。此外，这些表面活性剂表现出良好的起泡性和稳定性，这归因于更快的单体吸附和小气泡尺寸，这是清洁应用的首选。此外，与其他常用的传统阴离子 [十二烷基硫酸钠 (SLS)]、两性离子 [椰油酰胺丙基甜菜碱 (CAPB)] 和非离子 [癸基葡糖苷 (DG)] 相比，这些表面活性剂的低蛋白质/脂质增溶作用表明其在皮肤上的表现温和表面活性剂。粘度测量表明表面活性剂在辅助表面活性剂如氧化月桂胺存在下具有良好的增稠能力。
