Simethicone oil

The most critical specification is viscosity, typically measured in centistokes (cSt), ranging from 0.65cSt to 1,000,000cSt. For industrial use, focus on flash point and volatile content (should be <1%). For medical or cosmetic grades, ensure the purity level is >99% and check for the absence of heavy metals and residual catalysts.

Grade distinction is based on refinement and certification. Industrial grade is used for lubricants or defoamers. Cosmetic grade must meet INCI standards for skin safety. Food and Pharma grades require strict compliance with USP, EP, or FCC (Food Chemicals Codex) standards and must be produced in GMP-certified facilities to ensure they are non-toxic and safe for ingestion or topical application.

Buyers must verify REACH compliance for the EU market to ensure chemical safety. A comprehensive Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) is mandatory for shipping. For specialized applications, look for ISO 9001 (Quality Management) and ISO 22716 (Cosmetic GMP) certifications.

It is widely used as an anti-foaming agent in chemical processing, a lubricant for plastic and rubber molds, and a base ingredient in personal care products like hair conditioners and skin creams. In the medical field, it serves as an active pharmaceutical ingredient (API) for anti-gas medications.

The primary risk is specification mismatch, where the delivered viscosity does not match the order. Always request a Pre-Shipment Inspection (PSI) and a Certificate of Analysis (COA) for every batch. Another risk is leakage during transit; ensure the supplier uses UN-approved high-density polyethylene (HDPE) drums or steel drums with internal coatings.

Simethicone pricing is sensitive to raw material (silicon metal) fluctuations. Negotiate for formula-based pricing if signing long-term contracts. For MOQs, while standard is 200kg (one drum), many suppliers on Made-in-China.com offer smaller sample sizes (1kg-5kg) for quality validation before bulk commitment.

While Simethicone is generally classified as non-hazardous for transport (unless it has a very low flash point), you must provide the Certification for Safe Transport of Chemical Goods. For sea freight, use FCL (Full Container Load) to prevent cross-contamination with other chemicals, and ensure the HS Code (typically 391000) is correctly declared for customs clearance.

Utilize Secured Trading services provided by platforms like Made-in-China.com to hold payments until shipping documents are verified. Conduct a factory audit (either virtual or third-party like SGS/Intertek) to confirm the supplier is a genuine manufacturer and not a trading company with no quality control.
