Surfactant composition and preparation method thereof

The invention relates to a surfactant composition and a preparation method thereof, and mainly solves the technical problem that in the prior art, fatty alcohol-polyoxyethylene ether sulfate or fattyalcohol sulfate is prone to pH reduction, and the surfactant composition comprises the following components: a pH stabilizer; an anionic surfactant, wherein the anionic surfactant comprises fatty alcohol polyoxyethylene ether sulfate and/or fatty alcohol sulfate; the pH stabilizer comprises a stabilizer A and a stabilizer B; the stabilizer A is citric acid or citrate; the molecular structure of the stabilizer B contains an aromatic ring, and carbon forming the aromatic ring comprises carbon connected with phenolic hydroxyl and ortho-position carbon of the carbon connected with the phenolic hydroxyl as follows: the ortho-position carbon is connected with a tertiary carbon group so that the technical problem is better solved, and the surfactant composition can be used for surfactant composition production. 本发明涉及表面活性
