Introduction: Why Are Polyquaternium-42 and Polixetonium Chloride Confusing Buyers?
When sourcing specialty chemicals, buyers often encounter different names for what appears to be the same product.
One common example is Polyquaternium-42 and Polixetonium Chloride.
A buyer may search for:
“Polyquaternium-42 supplier”
but receive results showing:
“Polixetonium Chloride 60% solution”
This naturally raises a question:
Are Polyquaternium-42 and Polixetonium Chloride the same chemical, or are they different products?
The short answer is:
Yes. In most industrial applications, Polyquaternium-42 and Polixetonium Chloride refer to the same polymeric quaternary ammonium compound with CAS No. 31512-74-0.
The difference mainly comes from naming systems used by different industries.
What Is Polyquaternium-42?
Polyquaternium-42 is a cationic polymer belonging to the Polyquaternium family.
The name “Polyquaternium” is commonly used in ingredient naming systems, especially in industries where polymer functionality and composition need to be identified.
The number after Polyquaternium is an identification number.
For example:
- Polyquaternium-7
- Polyquaternium-10
- Polyquaternium-37
- Polyquaternium-42
The number does not represent:
- concentration
- purity
- molecular weight
- active percentage
Polyquaternium-42 contains quaternary ammonium groups, giving the polymer a positive charge.
This cationic structure is responsible for many of its important properties, including:
- adsorption ability
- interaction with negatively charged surfaces
- antimicrobial activity
- polymeric film-forming characteristics
What Is Polixetonium Chloride?
Polixetonium Chloride is the chemical name more commonly used in industrial water treatment and biocide markets.
Its chemical description is:
Poly[oxyethylene(dimethyliminio)ethylene(dimethyliminio)ethylene dichloride]
The main identification:
CAS No.: 31512-74-0
Commercial Polixetonium Chloride is usually supplied as a concentrated liquid solution, commonly:
60% active solution
Typical characteristics:
- Amber clear viscous liquid
- Cationic polymer
- Non-oxidizing biocide
- Non-foaming
- Compatible with many water treatment systems

What Is Polixetonium Chloride?
Are Polyquaternium-42 and Polixetonium Chloride the Same Chemical?
Yes, in most commercial and industrial contexts.
Polyquaternium-42 is generally considered the naming identity of the same polymer that is commercially known as Polixetonium Chloride.
The relationship can be understood like this:
| Name | Purpose |
|---|---|
| Polyquaternium-42 | Polymer identification name |
| Polixetonium Chloride | Chemical / industrial name |
| WSCP | Water treatment industry name |
| Polyquat 60 | Pool chemical market name |
Why so many names?
Because chemicals often receive different names based on:
- industry
- region
- application
- historical usage
A swimming pool professional may ask for “Polyquat 60”.
A water treatment engineer may request “Polixetonium Chloride”.
A technical document may mention “Polyquaternium-42”.
They may all be referring to the same chemistry.
Why Do Different Industries Use Different Names?
This is where many international buyers become confused.
Chemical naming is not always universal in commercial communication.
Water Treatment Industry
The preferred term is usually:
Polixetonium Chloride
because buyers focus on:
- active ingredient
- CAS number
- biocide performance
- technical specifications
Swimming Pool Industry
The common terms are:
- Polyquat 60
- Non-foaming polymeric algaecide
because these names are easier for distributors and pool professionals to understand.
Polymer and Ingredient Discussions
The term:
Polyquaternium-42
may appear because it describes the polymer identity.
So, the same material may appear under different names depending on who is using it.
CAS Number: How to Confirm Chemical Identity
When chemical names become confusing, CAS numbers provide the most reliable reference.
For Polyquaternium-42 / Polixetonium Chloride:
CAS No.: 31512-74-0
When contacting suppliers, buyers should confirm:
- CAS number
- Active content
- Appearance
- pH
- Density
- Viscosity
For example, a typical 60% Polixetonium Chloride solution may have:
| Property | Typical Range |
|---|---|
| Active Content | 58–61% |
| Appearance | Amber clear viscous liquid |
| pH | 6.0–8.0 |
| Density | Around 1.15 g/cm³ |
A product name alone is not enough.
Two suppliers may use similar names but offer products with different specifications.
Common Names and Trade Names of Polyquaternium-42
During sourcing, buyers may encounter several names.
Polixetonium Chloride
The preferred industrial chemical name.
Polyquaternium-42
The polymer identification name.
WSCP
Commonly used in water treatment and pool applications.
Polyquat 60
A popular pool industry description referring to polymeric quaternary ammonium algaecide products.
A commercial product name associated with Polixetonium Chloride chemistry.
Busan 77
These names may look different, but buyers should always check the CAS number and technical specifications.
Commercial Grades and Supply Forms
Polyquaternium-42 / Polixetonium Chloride is generally supplied as an aqueous liquid solution.
The most common commercial form is:
60% solution
Why?
Because higher concentration products may become difficult to handle due to:
- increased viscosity
- transportation challenges
- mixing difficulties
The 60% solution provides a practical balance between:
- active ingredient content
- storage stability
- handling convenience
