D-limonene is the main composition of the orange peel essential oil and it has strong detergency, natural fragrance and antimicrobial activity. In this paper, the recipe ratios of orange peel essential oil, sodium dodecyl sulfonate, triethanolamine were studied for the preparation of a "green" eco-friendly paste detergent by the single factor experiment in comparing the detergency. The optimum ratio was D-limonene: 5.0 %, sodium dodecyl sulfonate: 13.6 %, ethanol: 4.4 %, triethanolamine: 29.0 %, sodium chloride: 2.2 %, and distilled water: 45.8 %. The detergency of the paste detergent containing orange essential oil was compared with the commercial detergent. The results showed that the detergency of the paste detergent containing orange essential oil was almost same with commercial detergent (detergency ratio was 1 : 1). Also its detergency was more superior for resin dirt than commercial detergent (detergency ratio was 1.2).%橘皮精油的主要成分D-柠檬烯具有较强的去污能力、天然的芳香味及抑菌功效。本论文以去污力为考察指标，通过单因素实验研究了橘皮精油，十二烷基磺酸钠及三乙醇胺的配比，制备出一种去污力较强的“绿色”环保型洗涤膏。其最佳配比为：D-柠檬烯：5．0％，十二烷基磺酸钠：13．6％，乙醇：4．4％，三乙醇胺：29．0％，氯化钠：2．2％，蒸馏水：45．8％。并对含橘皮精油的洗涤膏、市售洗涤剂的洗涤去污效粜进行了比较研究。测试结果表明，所制备的含橘皮精油洗涤膏与市售洗涤剂沈涤效果相当（去污比值约为1），且在洗涤树脂类污垢优于市售洗涤剂（去污比值为1．2）。
