摘要

全球对过渡到更具可持续性的表面活性剂技术的需求日益增长。为了实现这一愿景,人们正在探索生物基表面活性剂和生物表面活性剂作为传统石化表面活性剂的替代品。然而,向这些技术的过渡预计将是渐进的,因此亟需将新型生物表面活性剂与烷氧基化物、硫酸盐和胺氧化物等传统表面活性剂结合使用,以实现性能、成本和可持续性之间的平衡。为此,我们报告了一项关于槐脂类生物表面活性剂对醇聚氧乙烯醚浊点以及烷基硫酸盐/胺氧化物混合物表面张力和发泡的影响的研究。我们惊人地发现,高酸槐脂类生物表面活性剂可以充当高效的加氢剂,提高醇聚氧乙烯醚的浊点。在硫酸盐/胺-氧化物混合物中,实验数据模型表明,高酸性和高内酯槐脂均可取代 40-50% 的主表面活性剂,而不会对表面张力或发泡性能产生显著变化。这些发现将有助于实现下一代高性能可持续清洁配方。

The interfacial properties of biosurfactant mixtures

There is growing global demand to transition to more sustainable surfactant technologies. Towards this vision, bio-based surfactants and biosurfactants are being explored as alternatives to traditional petrochemical surfactants. However, the transition towards these technologies is expected to be gradual, therefore there is a critical need to formulate new biosurfactants in combination with traditional surfactant classes such as alkoxylates, sulfates and amine-oxides to achieve a balance of performance, cost, and sustainability. To this end, we report a study of the impact of sophorolipid biosurfactants on the cloud point of alcohol ethoxylates, and on the surface tension and foaming of alkyl sulfate/amine-oxide mixtures. We make the surprising finding that high-acid sophorolipids can act as highly efficient hydrotropes and increase the cloud point of alcohol ethoxylates. In sulfate/amine-oxide mixtures, models of experimental data suggest that both high-acid and high-lactone sophorolipids can replace 40–50% of the primary surfactants without significant changes to the surface tension or foaming performance. These findings will enable the next-generation of high performing sustainable cleaning formulations to be realized.
