Development of chlorine-containing detergent and disinfectants based on ampholyte surfactant alkyldimethylamine oxide

Abstract

Purpose. Compare the stability of sodium hypochlorite (according to the loss of active chlorine) in the presence of an ampholytic surfactant – alkyldimethylamine oxide (amine oxide) from different manufacturers. Materials and Methods. Determination of the mass fraction of active chlorine in the manufactured samples of detergents and disinfectants was carried out by the method of iodometric titration. Results. Three samples of a hypochlorite detergent-disinfectant using amine oxide from various manufacturers were studied: Aromox 14D-W970 (Nouryon company), Ammonyx LO (Stepan company), alkyl dimethylamine oxide (Monastyrikha Chemical Plant LLC). The initial content of active chlorine in all samples was 1.8% wt. The period of observation of the samples was 14 months. Hypochlorite detergent-disinfectant based on amine oxide produced by Monastyrikha Chemical Plant LLC can have a shelf life of not more than 6 months, based on Aromox 14D-W970 – 12 months, based on Ammonyx LO – 8 months. Conclusion. Thus, the stability of sodium hypochlorite (according to the loss of active chlorine) in the composition of detergents and disinfectants, which includes an ampholytic surfactant - amine oxide from various manufacturers, was studied. Taking into account the above factors, a hypochlorite detergent-disinfectant can be manufactured in two versions: the first is a cheaper product with a 6-month shelf life based on alkyl dimethylamine oxide LLC Monastyrikha Chemical Plant, the second is a product with a 12-month shelf life based on Aromox 14D-W970.
