Need a water-treatment chemistry we don't list?
Custom quats and surfactants to specification for biocide, corrosion, deposit-control, and cleaning programs, from molecular design through pilot-scale production.
- Corrosion inhibitors matched to your water chemistry, conductivity, and dosing method
- Low-foam surfactant packages tuned to membrane compatibility and rinse-out
- Biofilm-penetrant blends built around the bis-quat base
- Registered-active grades and end-use registrations under the regulatory platform
- Concentrated and pumpable grades at the activity you dose
Frequently asked
Which actives can be used as water-treatment biocides?
The registered grades: 2D 50e (DDAC), 2OD 80e (dialkyl blend), CB 80e (ADBAC), and MBEB 80e (dual quat), with 2D 80e and CB 50e in review. Your biocide product is registered on ours under the formulator’s exemption or as a supplemental registration. The unregistered quats on this page are for corrosion inhibition, separation, and formulation.
Are the biofilm penetrants biocides?
No. They are surfactant packages that disperse biofilm and deposits so that a registered biocide or a cleaner can reach the surface; they carry no antimicrobial claim.
Which surfactants are safe on polyamide RO membranes?
The low-foam amphoterics and hydrotroping grades: decylamine oxide, capryl/capramidopropyl betaine, sodium caprylyl sulfonate, disodium cocoamphodiacetate, and sodium cocoamphoacetate. Cationic quats should be kept away from polyamide membranes except as a validated sanitizer.
Can the registered actives be used in pool and spa algaecides?
Yes. Quaternary algaecides for swimming pools, spas, fountains, and ponds are end-use products registered on ADBAC and DDAC manufacturing-use actives; CB 80e and 2D 50e are the registered grades, and the algaecide claims are made on your end-use registration.
Which corrosion inhibitor for hard or high-conductivity water?
The ethoxylated quats (EQ C15, EQ T15) and the bis-quats (DCE 1214, DCE 810) remain soluble and film-forming where conventional quats precipitate; the sarcosinate suits closed loops and aqueous fluids.
