Tetrakis(hydroxymethyl)phosphonium Sulfate (THPS)
Tetrakis(hydroxymethyl)phosphonium Sulfate (THPS) is a phosphonium-based industrial biocide used where sulphate-reducing bacteria, biofilm and the microbially influenced corrosion that follows them are the problem. Its commercial distinction is that it degrades quickly in the environment after use and also carries iron-sulphide dissolving character, so it is used both as a microbial control agent and as part of iron-sulphide scale management in oilfield water systems. Allzone quotes this material per enquiry: grade, packing, origin, documentation and Incoterm are decided in your quotation, not fixed by this page.

Technical & procurement detail
What THPS does in a water system+
It acts against planktonic and sessile bacteria, including the sulphate-reducing populations behind souring and microbially influenced corrosion, and it helps disperse and dissolve iron sulphide deposits that shelter those populations. It is dosed as part of a treatment programme, and the dosing regime — continuous or slug — is a programme design decision for your treatment provider.
What decides the grade you actually need+
The organism population, the system and the discharge constraint decide the biocide. State the water system, the microbial problem you are treating, the existing biocide programme, any compatibility constraint with corrosion inhibitors already dosed, and the regulatory or discharge requirement that applies. Product registration status for a given use in Canada is confirmed for the specific material and intended application before supply — it is never assumed from this page.
THPS against other microbial control chemistries+
Glutaraldehyde, isothiazolinone biocides and benzalkonium chloride each have their own canonical pages on this catalogue and are different chemistries with different spectra, compatibilities and handling requirements. THPS is a phosphonium chemistry, not a grade of any of them. Solution strengths, blended biocide programmes and packaging formats are handled inside this record and never published as separate pages.
Specification conventions and how to state yours+
Suppliers report active content, solution strength, particle presentation and impurity limits in different conventions, and the numbers are not interchangeable between them. State the convention your specification uses along with the property window you actually need, and comparison is made like for like against producer data for the grade offered.
What this page does not state+
This page asserts no purity, assay, active content, concentration, moisture, pH, density, dosage rate, performance figure, approval, registration, certification, origin, packing, minimum quantity, availability, lead time or price. Every commercially meaningful value is taken from producer documentation for the exact grade offered and confirmed in writing before order.
Sourcing and origin+
Allzone sources this material through producer channels and quotes it per enquiry. Origin, production route and shipping point are selected against your technical requirement, quantity, documentation need and destination, and are stated in the offer rather than fixed by this page. Freight, discharge point and packaging format move landed cost, so quotations are compared delivered to your plant.
Documentation supplied with an offer+
Technical data sheet, safety data sheet and certificate of analysis for the exact grade offered are requested from the producer and shared with the quotation. Handling, storage, incompatibility and personal-protection requirements are treated as SDS questions for the specific grade rather than figures published here. Where a declaration matters to your application — food contact, cosmetic, potable water, feed or regulatory — it is confirmed for that grade and intended use rather than assumed from this page.
How Allzone quotes this+
Send the process it goes into, the function you need it to perform, the property window your specification calls for in your own convention, the annual and per-shipment quantity, the packaging format your intake can receive, the documentation required per shipment and the delivery province or port. Several materials can be listed in one enquiry and reviewed together rather than split into separate requests.
Frequently asked questions
Does Allzone publish a price for tetrakis(hydroxymethyl)phosphonium sulfate (thps)?+
No. Price, minimum quantity, origin, packing and lead time depend on the grade, the volume and the destination, and are confirmed at quotation. Nothing on this page is an offer.
Which grades or presentations can be quoted?+
Aqueous solution presentations, Blended biocide programmes, Regulatory status for the intended use are handled inside this single product record. Grades, concentrations and applications of one material are not published as separate pages; the grade offered and its published data are confirmed in the quotation.
What documentation is available for tetrakis(hydroxymethyl)phosphonium sulfate (thps)?+
Technical data sheet, safety data sheet and certificate of analysis for the exact grade offered are requested from the producer and shared with the quotation. Handling, storage, incompatibility and personal-protection requirements are treated as SDS questions for the specific grade rather than figures published here. Where a declaration matters to your application — food contact, cosmetic, potable water, feed or regulatory — it is confirmed for that grade and intended use rather than assumed from this page.
