Sustainable detergents

衣物和织物的洗涤是一项常规活动，其原因有多种，其中最重要的是保持卫生、社会礼仪、外观和织物的使用寿命。在工业化国家，洗衣是用洗涤剂使用器具，如隧道洗衣机或家用洗衣机，在远高于室温的温度下使用处理/净化水。在发展中国家，通常是用当地的水和某种形式的洗涤剂洗手。在这两种情况下，洗涤剂废物最终暴露于环境。洗涤受四个因素影响，通常称为Sinner因素：（a）化学品/洗涤剂（B）温度（c）时间/持续时间（d）机械。这是一个高耗能、高耗水的过程，而且表面活性剂往往对生态系统造成污染。通过设计具有一种以上协同作用的表面活性剂的洗涤剂，可以（a）通过降低洗涤温度来降低能耗，（B）使用更少量的水，以及（c）使用更少量的洗涤剂-所有这三个都是可持续性的关键。

Laundering of clothing and fabric is a regular activity required for multitude of reasons, not least of which are maintaining hygiene, social decorum, appearance, and life time of the fabric. In industrialised countries, laundry is done with detergents using appliances such as tunnel washers or domestic washing machines, at temperatures well above room temperature using treated/purified water. In developing countries, often it is done by hand washing with water from local sources and some form of detergents. In both the cases, the detergent wastes are finally exposed to environment. Laundering is affected by four factors, often called Sinner's factors: (a) chemicals/detergents (b) temperature (c) time/duration (d) mechanical. It is an energy intensive and water consuming process, and the surfactants are often contaminative to ecosystem. By designing detergents with more than one surfactants, which acts synergistically, it is possible to (a) reduce the energy consumption by reducing washing temperature, (b) use less amount of water and (c) use less amount of detergent- all three are key for sustainability.
