The invention belongs to the technical field of cosmetics, and particularly discloses a stable one-phase-implementation solubilization method, which comprises the following steps of S1, firstly mixing an oil component with a hydrophilic surfactant, and making the oil component combine with a lipophilic group of the hydrophilic surfactant; S2, dissolving the oil component and the hydrophilic surfactant in polylol, so as to form a non-aqueous phase; S3, carrying out one phase implementation through a little water, and then thinning by using the water, so as to achieve solubilization. The solubilization method provided by the invention is simple and convenient to operate, can be used for realizing the long-time and stable storage of a more difficult oil component and guaranteeing the effect of a system, and is good in application prospect.
