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

Abstractcts-9985580 W. Kaler，《特拉华州立大学/假设：自然环境的关注》推动了对可生物降解或可以从可再生资源合成的基于表面活性剂的配方的需求。 含有烷基聚葡萄糖苷表面活性剂的混合物在这两项方面都成功。 提出了一项基本研究，该研究是针对含有烷基聚葡萄糖苷表面活性剂的混合物，以使其在大量重要的制剂和应用中用作其他类型的表面活性剂（尤其是乙氧基化醇）的潜在替代。 目标1是根据相行为和相应的微观结构来研究水烷基聚葡萄糖苷的混合物，包括探索添加剂，例如盐，酒精或其他表面活性剂对相行为和微观结构的影响。 目标2是检查含有非极性溶剂的混合物以及随后的微乳液形成。 将盐，酒精或其他表面活性剂等材料添加到水/油/烷基聚葡萄糖苷的微乳液中可能会对相行为和微观结构进行有益地影响，并允许对特定应用定制配方。 有人建议检查使用其他环境兼容材料的可行性，作为烷基聚糖糖苷微乳液的溶剂和添加剂。 这些类型的材料的例子包括柠檬烯（源自橙色加工），强奸种子油，其他天然衍生的油，以及使用烷烃作为烷醇的替代品。 目标3是通过添加天然存在的聚合物（例如，明胶和牙龈）来修饰其流变学性质和微观结构来扩展基于烷基聚葡萄糖苷的混合物的实用性。 将检查几类具有不同功能和增厚机制的工业重要牙龈。采取：实验方法涉及使用视觉上的微观观察结果确定表面活性剂相行为，这是化学类型，浓度和温度的函数。 将使用荧光光谱以及光和小角度X射线和中子散射方法来确定和定量微观结构。预期的结果：该工作将为使用烷基多葡萄糖表面表面活性剂作为替代在包括表面清洁剂，个人护理产品，个人护理产品，工业润滑剂在内的各种应用中的其他应用中的甲基烷基多葡萄糖表面表面。 这项工作还可能会发现这些新材料的特征，这些特征将优于常规配方，尤其是在温度敏感性，流变特性和成本的领域。 完成工作会降低环境风险，因为它直接导致配方的发展，这通过改善生物降解性和使用可再生资源对环境的影响降低了。Suppremprement关键词：废物最小化，环境化学和表面活性剂
