Observation of the stability of compound didecyl dimethyl ammonium chloride disinfectant
Objective To observe the stability of compound didecyl dimethyl ammonium chloride disinfectant.Methods Though influencing factor test,accelerated test and long-term test,the solution properties,chloride identification,clarity and effective content of the compound didecyl dimethyl ammonium chloride disinfectant were evaluated.Results The disinfectant was stored at(4 500±500)lx under strong light conditions for 10 days,light had an effect on the disinfectant,and the storage conditions should be shading and sealed storage.Stored at 60℃for 10 days,there was no significant change in the indicators.Stored for 6 months at(40±2)℃with relative humidity of(75±5)%,there was no significant change in the indicators.Stored for 6 months at(25±2)℃with relative humidity(60±5)%,there was no significant change in the indicators.Conclusion The compound didecyl dimethyl ammonium chloride disinfectant is recommended to be stored under shading,sealed storage,and the validity period is at least 12 months.
