ABSTRACTCTS-9985580Eric W. Kaler, U of DelawareObjectives/Hypothesis: Concern for the natural environment drives a need for surfactant-based formulations that are biodegradable or that can be synthesized from renewable resources. Mixtures containing alkylpolyglucoside surfactants succeed on both counts. A fundamental study is proposed of mixtures containing alkyl polyglucosides surfactant to enable their use as potential replacements for other types of surfactants (in particular ethoxylated alcohols) in a large number of industrially important formulations and applications. Objective 1 is to study water-alkyl polyglucoside mixtures in terms of phase behavior and the corresponding microstructure, including exploration of the effects of additives such as salt, alcohol, or other surfactants on the phase behavior and microstructure. Objective 2 is to examine mixtures containing nonpolar solvents and the subsequent formation of microemulsions. Adding materials such as salt, alcohol, or other surfactants to water/oil/alkyl polyglucoside microemulsions may effect the phase behavior and microstructure beneficially and allow tailoring of formulations to specific applications. It is proposed to examine the feasibility of employing other environmentally compatible materials, as solvents and additives to alkylpolygucosides microemulsions. Examples of these types of materials include limonene (derived from orange processing), rape seed oil, other naturally-derived oils, and also the use of alkanediols as substitutes for alkanols. Objective 3 is to extend the utility of alkyl polyglucoside-based mixtures by modifying their rheological properties and microstructure through addition of naturally occurring polymers (e. g., gelatin and gums). Several classes of industrially important gums with different functionality and thickening mechanisms will be examined.Approach: The experimental approach involves determination of surfactant phase behavior using visual a microscopic observation of mixtures as a function of chemical type, concentration, and temperature. Microstructure will be determined and quantified using fluorescence spectroscopy and light and small angle x-ray and neutron scattering methods.Expected Results: The work will provide a scientific basis for the use of alkyl polyglucoside surfactants as replacements for other nonionic formulations in a variety of applications including surface cleaners, personal care products, and industrial lubricants. The work will also likely uncover features of these new materials that will be superior to conventional formulations, particularly in the areas of temperature sensitivity, rheological properties, and cost. Completion of work reduces environmental risk because it leads directly to the development of formulations, which have a reduced impact on the environment via improved biodegradability, and the use of renewable resources.Supplement Keywords: Waste minimization, environmental chemistry, and surfactants

摘要-9985580 Eric W. Kaler，特拉华大学目标/假设：对自然环境的关注推动了对可生物降解或可由可再生资源合成的表面活性剂配方的需求。 含有烷基聚葡糖苷表面活性剂的混合物在这两个方面都取得了成功。 提出了对含有烷基多葡糖苷表面活性剂的混合物的基础研究，以使它们能够在大量工业上重要的制剂和应用中用作其他类型的表面活性剂（特别是乙氧基化醇）的潜在替代品。 目的一是研究水-烷基糖苷混合物的相行为和相应的微观结构，包括探索添加剂如作为盐、醇或其它表面活性剂对相行为和微观结构的影响。 目的2是研究含有非极性溶剂的混合物和随后形成的微乳液。 向水/油/烷基聚葡糖苷微乳液中添加材料如盐作为盐、醇或其它表面活性剂可有益地影响相行为和微结构，并允许针对特定应用定制制剂。 建议研究采用其他环境相容性材料作为烷基葡糖苷微乳液的溶剂和添加剂的可行性。 这些类型的材料的实例包括柠檬烯（衍生自橙子加工）、菜籽油、其它天然衍生的油，以及使用烷二醇作为烷醇的替代物。 目的3是通过添加天然存在的聚合物（例如，聚葡萄糖苷）来改变其流变学性质和微观结构，从而扩展烷基聚葡萄糖苷基混合物的实用性。例如，在一个实施例中，明胶和树胶）。 几类工业上重要的胶具有不同的功能和增稠机制将examined.Approach：实验方法涉及到确定表面活性剂的相行为使用视觉显微镜观察的混合物作为一个功能的化学类型，浓度和温度。 微观结构将被确定和量化使用荧光光谱和光和小角度X射线和中子散射methods.Expected结果：这项工作将提供一个科学依据，烷基聚葡萄糖苷表面活性剂作为替代品，其他非离子配方在各种应用，包括表面清洁剂，个人护理产品，和工业润滑油。 这项工作还可能揭示这些新材料的特性，这些特性将上级传统配方，特别是在温度敏感性，流变性能和成本方面。 工作的完成降低了环境风险，因为它直接导致配方的开发，通过改善生物降解性和使用可再生资源来减少对环境的影响。补充关键词：废物最小化，环境化学和表面活性剂
