Products called Kathon cause changes in process color or deposits
Check stabilizers, impurities and the specific formulation.
Separate actives are shown. Composition and ratio are grade-specific.

- Component ratios and total active contentStabilizers and metal saltspH, temperature and existing additivesDestination labels and use categories
- Packaging and delivery
- Confirm original container materials, closed-withdrawal connections and contamination-prevention requirements; packaging documents must match the CMIT/MIT product rather than attach information for one component only.
Identity and physical form identify the product; specific concentration, grade, packaging and uses are governed by mutually confirmed formulated-product documents.
01 / Product and applications
Uses and product form
Chemical identity / Technical type
A specific CMIT and MIT formulation; BIT, OIT and DCOIT are not treated as the same product on this page.
Appearance and delivery form
Public cooling-water information lists liquid formulations; TDS/SDS must confirm actual color, stabilizing salts and solvent system.
Identity note
This page concerns CMIT/MIT formulations and lists two active-component CAS identifiers for searching. No single CAS is assigned to a product with unspecified ratio and stabilization system. BIT, OIT and DCOIT are other compounds; the broad isothiazolinone name cannot replace identification.
02 / Specification selection
Key purchasing parameters
| Items to confirm | Relevance to purchasing and use |
|---|---|
| Component ratios and total active content | Distinguish different specifications sharing a name. |
| Stabilizers and metal salts | Affects process and downstream requirements. |
| pH, temperature and existing additives | Assess stability and compatibility. |
| Destination labels and use categories | Material-preservation and process-water uses cannot be inferred from one another. |
Include parameters, test methods and acceptance checkpoints in purchasing requirements to compare specifications.
03 / Applications and limits
Applications and conditions of use
These are starting points for conditional verification. Specific product suitability still requires joint confirmation through product documents, operating conditions and destination requirements.
Additional checks before use
- The generic isothiazolinone name cannot justify substitution of other chemical types.
- Industrial-water uses cannot be applied to drinking water or bathing pools.
- Product eligibility for different countries and uses requires independent verification.

06 / Frequently asked questions
Purchasing FAQs
Are Kathon-type CMIT/MIT and DCOIT the same substance?
No. Related chemical families do not imply identical components, stability or uses.
Why ask about stabilizing salts?
Stabilization systems may affect processes, deposits and downstream water quality.
Are blends always more effective?
Compare efficacy and compatibility in actual water samples; ingredient count cannot decide this.

CMIT/MIT / Bronopol blends
CMIT/MIT + BP
A non-oxidizing blend type documented in public cooling-water information. Identify both groups of active ingredients and the stabilization system, and confirm the actual water circuit rather than borrowing uses established for coating preservation.

Manufacturers offer specific formulations for industrial water microbial and algae control. Verify the dispersion system and industrial water uses of the formulated product; products for coatings or antifouling materials cannot be substituted directly.

Bronopol
Bronopol
For industrial water microbial control products with defined uses. Check active ingredients, formulation compatibility and actual operating conditions, and distinguish single-active products from formulated blends.

Identity and specifications
Why is one total concentration insufficient when purchasing Kathon-type products?
Isothiazolinone is a chemical category, and Kathon may refer in commercial communication to different CMIT/MIT products. Purchasing requirements must identify the specific active combination, formulation and use, not just an abbreviation and percentage.

Process compatibility
Process problems after CMIT/MIT use in paper white water: how should compatibility investigation be arranged?
Biocidal efficacy and stable paper-machine operation must both be achieved. If foam, deposits or quality changes follow an isothiazolinone product change, investigate the formulation and white-water additive system together rather than focus only on microbial counts.

Purchasing Documents
How much should buyers ask about an isothiazolinone formulation's stabilization system?
Stabilization may affect shelf life and process suitability, but buyers do not need the full proprietary formulation to compare effectively. Clarify use-related restrictions, validation conditions and quality parameters.
