Neutralizing whitening agent and preparation method thereof

Abstract

The invention discloses a neutralizing whitening agent and a preparation method thereof. The neutralizing whitening agent comprises the following components in parts by weight: 5-20 parts of citric acid, 1-5 parts of malic acid, 0.5-7 parts of oxalic acid, and 70-80 parts of water. The preparation method comprises the following steps: dissolving oxalic acid, malic acid and citric acid respectivelyby using 10-20 parts of water; mixing the three solutions uniformly; adding the remaining water and stirring the mixture uniformly. The neutralizing whitening agent comprising a plurality of mild organic acids breaks the single status of acid substances in the existing neutralizer products, makes up for the defect that the existing single acid neutralizer products cannot improve the whiteness ofcloth, and can effectively remove gray salt deposited on fabrics, increase the whiteness of cloth and cause the color of the cloth more vivid and bright. The neutralizing whitening agent can effectively neutralize alkaline substances and chlorine remaining in the cloth after washing with water, prevent chemicals from irritating the skin, eliminate the corrosion of residual alkali and bleaching agent on cloth fibers, and prevent the white cloth from yellowing and graying.
