Potassium cinnamate

Potassium Cinnamate is a natural-identical preservative primarily used for its broad-spectrum antimicrobial properties. In the food industry, it is an effective antifungal agent used in beverages, sauces, and pickled products, often serving as a clean-label alternative to sodium benzoate. In cosmetics, it functions as a fragrance stabilizer and skin-conditioning agent, providing protection against yeast and mold in formulations with a pH range of 3.0 to 6.0.

Buyers must ensure the product meets a purity level of ≥99% to minimize impurities that could affect the final formulation's stability. Key specifications include loss on drying (≤1.0%) and heavy metal content (Pb ≤2mg/kg, As ≤2mg/kg). It is critical to verify the solubility in water, as high-quality Potassium Cinnamate should be completely soluble to ensure uniform distribution in liquid applications.

For food-grade applications, the product must comply with FCC (Food Chemicals Codex) or USP (United States Pharmacopeia) standards. Suppliers should provide ISO 22000 or HACCP certifications for food safety management. If exporting to the EU, ensure the supplier provides a REACH registration or pre-registration number, and for the US market, FDA registration of the manufacturing facility is highly recommended.

Request a Stability Test Report from the supplier, which should demonstrate that the product maintains its potency for at least 24 months when stored in a cool, dry, and dark environment. Because Potassium Cinnamate is light-sensitive, ensure the packaging consists of UV-protected containers or double-layered black PE bags inside fiber drums.

The primary risks include purity fluctuations between batches and moisture absorption during maritime transit. To mitigate this, buyers should use Made-in-China.com's Secured Trading services and mandate a Pre-shipment Inspection (PSI) by third parties like SGS or Intertek to verify the Certificate of Analysis (COA) against the actual cargo.

For specialized chemical additives, tiered pricing is standard. Negotiate a lower MOQ for the initial trial order (e.g., 25kg/1 drum) to conduct lab testing. For bulk orders exceeding 500kg, aim for a 10-15% discount. Always clarify if the quoted price is FOB (Free On Board) or CIF (Cost, Insurance, and Freight) to avoid hidden logistics surcharges.

Potassium Cinnamate is generally classified as non-hazardous for transport, but you must obtain a Material Safety Data Sheet (MSDS) and a Non-Hazardous Chemical Declaration to prevent customs delays. Ensure the HS Code (typically 291639) is correctly declared to align with the specific import tariffs of your destination country.

Avoid direct wire transfers to unverified accounts. Utilize Escrow-based payment systems provided by reputable platforms like Made-in-China.com, where funds are only released to the supplier upon confirmation of receipt and quality validation. This protects the buyer against non-delivery or sub-standard goods.
