Efficient degreasant special for natural leather

The invention discloses an efficient degreasant special for natural leather, and relates to the technical field of leather processing. The efficient degreasant comprises raw materials, by weight, 15-20 parts of decyl glucoside, 10-15 parts of PEG-60 hydrogenated castor oil, 5-10 parts of lauroyl sodium glutamate, 5-10 parts of water treatment level polyglutamic acid, 1-5 parts of poloxamer 188, 1-5 parts of polyoxyethylene, 1-5 parts of chitosan quaternary ammonium salt, 0.5-3 parts of hydrolytic polymaleic anhydride and 0.1-1 part of ethylenediamine tetraacetic acid disodium salt. The degreasing rate of the prepared degreasant reaches 80% or above, the degreasant belongs to a low foam type degreasant, only a small quantity of foams are generated after the degreasant is dissolved into water, and therefore the follow-up water using quantity is reduced; and meanwhile, the prepared degreasant is mild in chemical property, and the fiber structure of the natural leather cannot be damaged. 本发明公开了种专用于天然皮革的高效脱脂剂，涉及皮革
