There Are 3 Types of “Food-Grade” Silicone Oil — Which One Does Your Application Actually Require?
“We need food-grade silicone oil.”
This is one of the most common statements in procurement discussions.
But once the supplier clarifies the intended application, it often becomes clear that the requested “food-grade” material may not match the actual regulatory framework required. In the worst-case scenario, choosing the wrong compliance standard can lead to shipment rejection — or even product recalls.
In reality, “food-grade silicone oil” is not a single concept. It corresponds to three major regulatory systems, each tied to entirely different application scenarios:
1️⃣ FDA 21 CFR 178.3570 (United States)
✅ Application: Lubrication points in food-processing equipment (e.g., conveyor bearings, filling pumps)
✅ Core requirement: Base oils and additives must be on the approved substance list; incidental contact limit typically ≤10 ppm
✅ Common certification: NSF International H1 registration (not mandatory, but widely recognized)
⚠️ Important: Not intended for direct food contact — only for incidental contact situations.
2️⃣ EU No 10/2011 (European Union)
✅ Application: Additives in plastic or silicone materials that directly contact food (e.g., silicone nipples, baking mats)
✅ Core requirement: Silicone oil as a polymer component must meet Specific Migration Limits (SML) and overall material compliance
✅ Key tests: Overall Migration Limit (OML), specific migration (e.g., D4/D5), heavy metals
⚠️ Important: FDA compliance alone does not guarantee eligibility for the EU market.
3️⃣ GB 4806.11-2016 (China)
✅ Application: Rubber/silicone food-contact products sold domestically (e.g., rice cooker sealing rings, baby pacifiers)
✅ Core requirement: Silicone oil must be permitted polydimethylsiloxane (PDMS); volatile content ≤0.5%; heavy metals compliant
✅ Related standard: GB 9685 for permitted additives
“Many clients assume that having an FDA certificate automatically means universal food-grade compliance,” a regulatory consultant explained. “But the three systems differ significantly in testing methods, migration limits, and permitted substance lists.”
Before purchasing, customers should clearly answer three key questions:
-
What is the final application? (Equipment lubrication / silicone raw material / defoamer?)
-
What is the target market? (China / U.S. / EU / Global?)
-
Will the material directly contact food? (Yes / No / Incidental only?)
Only by clarifying these points can the correct compliance pathway be selected.
As a professional silicone oil supplier, we provide:
-
Regulatory Declarations of Compliance (DoC)
-
Third-party test reports (e.g., SGS, CTI)
-
Application-specific product recommendations
“Food-grade” is not a marketing slogan —
It is a precise regulatory language that must match your application.
