Alkyl polyglycosides (APGs), based on renewable glucose and fatty alcohols, are recognized for their performance and biodegradability. Hydrotropic/solubilizing effect properties have already been identified on short-chain variants such as hexyl and ethylhexyl, but these ingredients were not fully bio-based. This study investigated the hydrotropic/solubilizing properties of eco-designed 100% bio-based heptyl glucoside, under various conditions, compared to industrial and personal care benchmarks and other short chain APGs. Foaming power was firstly evaluated at different temperatures with two static methods. Hydrotropic performance was assessed with a commonly used surfactant in the presence of high electrolyte, acid and alkali concentrations. Further trials were done using ethoxylated rapeseed oil as an oil lubricant model in electrolyte-charged aqueous solution. The solubilizing effect of hydrophobic additives such as fragrances, essential oils and vitamin E was quantified. Finally, effects on formulation preservation were screened with two natural personal care preservatives. Heptyl glucoside was found to be an effective and versatile hydrotrope for industrial applications, with additional intrinsic lubrication properties. It was also revealed as an efficient solubilizer for personal care products with the additional benefit of reducing the preservative dosage required in natural formulations. Its unusual non-foaming nature, while not disrupting the foaming capacity of surfactants, makes it suitable for all types of cleansers. The calculated carbon footprint has a low value, making heptyl glucoside a valuable ingredient combining both performance and low environmental impact.

用于清洁剂和洗涤剂的可持续糖脂水溶助长剂增溶剂

烷基多​​糖苷 (APG) 基于可再生葡萄糖和脂肪醇，因其性能和生物降解性而受到认可。已经在己基和乙基己基等短链变体上确定了水溶/增溶效应特性，但这些成分并非完全生物基的。本研究调查了生态设计的 100% 生物基庚基葡萄糖苷在各种条件下的水溶助长/增溶特性，并与工业和个人护理基准以及其他短链 APG 进行了比较。首先用两种静态方法评估不同温度下的发泡能力。在高电解质、酸和碱浓度存在下，使用常用的表面活性剂评估水溶助长性能。使用乙氧基化菜籽油作为带电解质的水溶液中的油润滑剂模型进行了进一步的试验。对芳香剂、精油和维生素 E 等疏水性添加剂的增溶作用进行了量化。最后，筛选了两种天然个人护理防腐剂对配方保存的影响。庚基葡萄糖苷被发现是一种适用于工业应用的有效且多功能的水溶助长剂，具有额外的固有润滑特性。它还被证明是个人护理产品的有效增溶剂，具有减少天然配方中所需防腐剂剂量的额外好处。其不寻常的不起泡特性，同时不会破坏表面活性剂的起泡能力，使其适用于所有类型的清洁剂。计算出的碳足迹值较低，使得庚基葡萄糖苷成为一种兼具性能和低环境影响的有价值成分。
