We coordinate supply by matching grade, documentation, and logistics lane to your formulation and destination requirements.
Industrial-use note: Bronopol is supplied for industrial formulation use where permitted by applicable laws and regulations. Always validate performance and compliance for your specific end-use, region, and labeling obligations before commercial launch.
Product overview
Bronopol is widely used as an antimicrobial preservative for water-based products where microbial contamination can degrade performance and shelf life. It is typically applied as an “in-can” preservative in formulations such as emulsions, dispersions, and cleaning products.
Targets
Broad activity against bacteria and many fungi/yeasts in compatible systems (program dependent). Target spectrum should be confirmed by challenge testing.
Where it fits
Water-based industrial formulations where controlled preservation is required, especially in products that experience repeated opening, warm storage, or long distribution chains.
Commercial value
Supports shelf-life targets and reduces scrap, rework, and returns caused by microbial spoilage—often lowering the total cost of quality.
How we supply
We align grade, active content, documentation pack, and logistics lane to your destination and operating model (spot vs. repeat supply).
Technical alignment
We collect your matrix, process, and constraints (pH, temperature, additives, micro-risk) to avoid misfit and minimize trial-and-error.
Note: Performance depends on formulation matrix, pH, temperature, contamination load, and compatibility with other raw materials. Always validate via lab/pilot testing and local regulatory requirements.
Typical applications
Commonly requested in water-based systems where product spoilage can cause quality claims, downtime, or customer returns. Share your formulation type and operating conditions and we’ll align a suitable grade and supply option.
- Water-based paints, coatings, and polymer dispersions (in-can preservation)
- Adhesives, sealants, and construction chemistry emulsions (microbial control during storage)
- Metalworking fluids and compatible process fluids (preservation programs)
- Industrial & institutional cleaners (water-based concentrates and ready-to-use products)
- Latex, slurries, and other water-based intermediates in production
- Paper & pulp additives and selected aqueous process formulations (program dependent)
Formulation reality check: Microbial control is not only chemistry—sanitation, water quality, packaging, and process hygiene strongly influence outcomes. Share your operating environment so we can account for contamination pressure and storage conditions.
Technical alignment
What technical teams typically confirm before approving a preservative biocide for production.
Compatibility screening
Confirm compatibility with your resin/emulsion system, surfactants, salts, fragrances, and other additives. Share any known “no-go” chemistries so we can pre-screen grade fit.
Process & addition point
Identify the best addition stage (often during cool-down or at a stable process point), mixing intensity, and hold times. Good dispersion reduces localized overconcentration and performance variability.
Micro-risk profile
Define contamination pressure (water quality, ambient temperature, repeated opening, storage duration, and hygiene controls). Higher risk environments may require program-based preservation rather than a single-active approach.
Performance verification
Preserve-by-design: validate using your internal protocol (e.g., storage stability, challenge testing, and in-use simulation). Confirm that product appearance, odor, viscosity, and stability remain within spec.
Quality & release checks
Typical checks include identity, assay/active content (grade-dependent), appearance, and moisture (powder grades). Final confirmation should rely on the batch COA supplied with your shipment.
Regulatory & labeling
Requirements vary by region and end-use. We can support your review with available SDS, COA, and origin documents, and help align the offer to your compliance constraints (where applicable).
Dose & program notes
Dose selection is formulation-specific. For many in-can preservation programs, dosages are determined by contamination pressure, matrix compatibility, and target shelf life rather than a single universal number.
- Start with lab screening; confirm with storage stability and in-use exposure conditions
- Consider water quality, sanitation, packaging, and headspace exposure
- If needed, evaluate a blended program approach (multi-active) with your technical team
We can help you structure the information needed for a faster technical review (matrix, constraints, and acceptance criteria).
Safety note: Use only in industrial applications aligned with applicable laws and regulations. Follow SDS guidance for handling, PPE, storage, and disposal.
Performance & use guidance
Practical formulation notes for procurement and technical alignment.
Typical dose range
Often applied in the low hundreds of ppm (active) depending on contamination pressure and matrix. Exact dosage must be confirmed via lab/pilot testing and local regulations.
Where to add
Typically added during cool-down or at temperatures aligned with formulation stability. Ensure good dispersion and avoid localized overconcentration.
Compatibility
Performance is influenced by pH, amines, reducing agents, and certain reactive components. Share your full recipe constraints for a compatibility check.
Program approach
Can be used as a standalone preservative or within multi-active programs depending on micro-spectrum needs, water quality, and in-use contamination exposure.
Micro-risk drivers
High organic load, warm storage, repeated container opening, and poor sanitation increase spoilage risk. Address hygiene and packaging alongside preservative selection.
Quality control
Typical procurement checks include assay/active content, appearance, moisture (for powder grades), and identification per supplier method.
Documentation & traceability (what you can request)
SDS
Safety, handling, transport classification (if applicable), exposure controls, and disposal guidance.
COA
Batch-specific test results (assay/active, appearance, and other grade-dependent parameters).
TDS
Typical properties, recommended handling, and grade description (availability varies by origin).
