According to the preparation method of the stable low-viscosity organic silicon emulsion, in the emulsion emulsification process, a mixture formed by compatibility of polyethylene glycol and polyethylene glycol fatty acid ester derivatives is introduced through high-speed shearing, the mixture can form a hydrogel state in an aqueous solution, and the thickening and stabilizing effects are excellent; meanwhile, the polyether modified polysiloxane has certain wire drawing and film forming properties, forms good wrapping on organic silicon active matters, and has a synergistic effect with the polyether modified polysiloxane, so that the emulsifying effect of the polyether modified polysiloxane is further improved, the stable and low-viscosity organic silicon emulsion is finally prepared, and the defoaming performance and the dispersing performance of the emulsion are improved; compared with a thickening agent used in the conventional preparation of the organic silicon emulsion, the stabilizing agent used in the
