Abstract
The invention discloses a compound preservative containing dimethyl 1,3-bis(hydroxymethyl)-5,5-dimethylimidazolidine-2,4-dione. The compound preservative is composed of the following components in mass percent: 10.0%-50.0% of dimethyl 1,3-bis(hydroxymethyl)-5,5-dimethylimidazolidine-2,4-dione, 0.1%-2.0% of chloromethyisothiazolinone or methylisothiazolinone, 0.1%-1.0% of a synergist and the balance of de-ionized water or purified water. A preparation method comprises the following steps: adding a quantitative amount of the synergist into the de-ionized water or the purified water; agitating and dissolving until the solution is clarified; then adding dimethyl 1,3-bis(hydroxymethyl)-5,5-dimethylimidazolidine-2,4-dione into the solution and uniformly agitating and mixing; and finally, adding chloromethyisothiazolinone or methylisothiazolinone and uniformly agitating and mixing to obtain the compound preservative. The compound preservative has the advantages of broad-spectrum antibacterial property, low irritation and no resistance.
