Abstract:

The surface activity, antistatic performance, salt resistance, acid and alkali resistance, metal corrosion, antimicrobial properties and biodegradability of cetrimonium formate (HTAF), cetrimonium acetate (HTAA) and cetrimonium butyrate (HTAE) were investigated, and the antibacterial properties and detergency of binary mixed systems of HTAF mixed with sodium alkylpolyoxyethylene sulphate (AES), sodium polyoxyethylene alkyl ether carboxylate (AEC-9Na) and alkyl glucoside (APG1214) were measured. The results are as follows: the critical micelle concentration (cmc) and the surface tension at cmc (γcmc) of HTAE are lower than that of HTAF and HTAA; the antistatic performance of HTAF and HTAA is basically at the same order of magnitude as traditional antistatic agent octadecyl dimethyl hydroxyethyl ammonium nitrate (SN), while the antistatic performance of HTAE is poor; three cetrimonium salts with organic counterions have exhibited strong salt resistance (>200 g/L) against either monovalent Na+or divalent Ca2+ and Mg2+, and have good acid and alkali resistance; their corrosiveness to metals is significantly lower than that of cetrimonium chloride (HTAC) ; the primary biodegradability after 7 days for three surfactants is greater than 98%; HTAF shows good antibacterial activity against Staphylococcus aureusS. aureus) and Escherichia coli E. coli) (>95%) even at a content of 20 mg/kg. The results of binary mixed systems show that, AES/HTAF mixed system has better detergency than that of standard laundry detergent, but has no antibacterial activity; AEC-9Na/HTAF mixed system has both excellent antibacterial performance and detergency; APG1214/HTAF mixed system has good antibacterial activity but poor detergency.

Key words: cetrimonium salts with organic counterions, antistatic property, metal corrosiveness, bacteriostasis, mixed system
