Methylisothiazolinone price

When sourcing MIT, the price is heavily influenced by the active ingredient concentration, typically ranging from 10% to 99% (pure grade). Buyers must verify the pH stability range (usually 2.0–12.0) and ensure the product is formaldehyde-free and low-VOC. For industrial applications, check the color APHA index; a lower value indicates higher purity, which prevents yellowing in end-products like paints or cosmetics.

Compliance is a critical cost driver. For cosmetic applications, MIT is strictly regulated; for instance, the EU Annex V restricts its use to rinse-off products only at a maximum concentration of 0.0015% (15 ppm). If purchasing for the US market, ensure the supplier adheres to CIR (Cosmetic Ingredient Review) guidelines. For biocidal use in industrial cooling or coatings, the product must comply with the BPR (Biocidal Products Regulation) or EPA registration, which may increase the premium on the unit price.

To optimize costs, evaluate the Total Cost of Ownership (TCO) beyond the sticker price. MIT is often sold as a water-based solution; therefore, shipping costs are high relative to the active material. Sourcing high-concentration concentrates (e.g., 50%) and diluting locally can reduce logistics expenses by up to 40%. Additionally, look for suppliers on Made-in-China.com who offer tiered pricing where the price per kg drops significantly for orders exceeding 1,000kg (1 Metric Ton).

MIT is a broad-spectrum biocide used to inhibit the growth of bacteria, fungi, and algae. Key scenarios include personal care products (shampoos, conditioners), water treatment systems, and polymer emulsions. Functional requirements include excellent water solubility, compatibility with surfactants and emulsifiers, and maintaining efficacy across a wide temperature range (up to 60°C).

The primary risks include chemical leakage during transit and customs seizure due to improper labeling. MIT is classified as a corrosive substance (UN 3265, Class 8) for shipping. Ensure the supplier provides a valid SDS (Safety Data Sheet) in the destination country's language and uses UN-approved packaging (HDPE drums) to prevent environmental hazards and legal penalties.

Utilize the Secured Trading services provided by Made-in-China.com to protect your payments. To ensure quality consistency, request a COA (Certificate of Analysis) for every batch and mandate a third-party pre-shipment inspection (such as SGS or Intertek) to verify that the active content matches the technical data sheet before the final balance is paid.

Focus on volume-based contracts rather than spot-buying to hedge against raw material price volatility. Negotiate for free samples (50g-100g) for lab testing before committing to bulk. Ask for transparency in the raw material supply chain (e.g., the cost of isocyanates) to better understand the supplier's pricing logic during annual contract renewals.

Since MIT is a hazardous chemical, it requires specialized dangerous goods (DG) forwarding. Confirm that the supplier has a 'Dangerous Goods Declaration' and that the shipping line accepts Class 8 chemicals. For sea freight, ensure the containers are stored away from heat sources to prevent chemical degradation, and always include marine insurance covering chemical spills.
