Alkyl β‐D‐maltosides are an important class of sugar‐based nonionic surfactants and have been widely studied. Nevertheless, it is still necessary to investigate further their amphiphilic structure‐surface property relationships. In this article, we reported a series of properties of synthetic alkyl β‐D‐maltosides (6a–6i, n = 6–18) including their hydrophilic–lipophilic balance (HLB) number, water solubility
烷基β-D-麦芽糖苷是一类重要的基于糖的非离子表面活性剂,已得到广泛研究。然而,仍然有必要进一步研究它们的两亲结构-表面性质关系。在本文中,我们报告了合成烷基β-D-麦芽糖苷(6a - 6i,n = 6-18),包括其亲水亲脂平衡(HLB)值,水溶性,吸湿性,保湿能力,起泡能力,表面张力,热致变相行为和皮肤刺激性。它们的HLB值和水溶性随着烷基链长度的增加而降低。己基β-D-麦芽糖苷表现出最强的吸湿性和保湿能力。癸基β-D-麦芽糖苷和十二烷基β-D-麦芽糖苷具有出色的发泡能力和发泡稳定性。此外,烷基β - D-麦芽糖苷的临界胶束浓度(CMC)(6a - 6g,n = 6-14)及其在CMC处的表面张力随着烷基链长度的增加而降低。最后,烷基β-D-麦芽糖苷(6a– 6g)在皮肤刺激性评估中应被视为安全的表面活性剂。
