High-concentration high-efficiency refined detergent

The invention relates to a high-concentration high-efficiency refined detergent which is prepared by mixing the following raw materials in parts by mass: 250 to 300 parts of fatty alcohol-polyoxyethylene ether, 5 to 10 parts of glacial acetic acid, 20 to 25 parts of iso-C10 fatty alcohol-polyoxyethylene ether, 120 to 140 parts of canola oil fatty acid diethanol amide, 150 to 170 parts of sulfoacid, 40 to 50 parts of urea, 50 to 60 parts of refined salt, 150 to 220 parts of water, 20 to 25 parts of NaOH, 5 to 10 parts of sodium benzoate and 30 to 40 parts of polyester. The high-concentration high-efficiency refined detergent does not contain harmful substances such as APEO (alkylphenol ethoxylates), NPEO (nonylphenol polyoxyethylene ether) and the like, is more healthy and environment-friendly, and meanwhile, has a better cleaning effect in the washing process. 种高浓高效精炼洗涤剂，由如下质量份的原料混合制成：250-300份脂肪醇聚氧乙烯醚、5-10份冰醋酸、20-25份异构C10脂肪醇聚氧乙烯醚、120-140份菜籽油脂肪酸二乙醇酰胺、150-170份磺酸、40-50份尿素、50-60份精盐、150-220份水、20-25份NaOH、5-10份苯甲酸钠以
