Food Grade Silicone Oil 100–1,500 cSt
What Is Food Grade Silicone Oil / Silicone Fluid?
Food grade silicone oil is a high-purity silicone fluid, typically based on polydimethylsiloxane (PDMS), specified for selected food-processing or food-contact applications under defined conditions.
PDMS is widely used because of its:
- Low surface tension
- Chemical inertness
- Thermal stability
- Lubricating properties
- Release performance
- Low reactivity
- Good surface spreading
FDA lists dimethylpolysiloxane for specific uses under several food-related regulations, including 21 CFR 173.340 and 21 CFR 178.3570. The applicable requirements depend on the intended application and conditions of use.
Therefore, food grade status should always be evaluated according to the specific product grade, application, concentration, food type, temperature, and regulatory requirements.

Key Properties
High Chemical Stability
Low Surface Tension
Excellent Thermal Stability
Good Lubricity
Good Release Performance
Main Applications
1. Food Processing Lubricant
- Conveyors
- Valves
- Seals and O-rings
- Filling equipment
- Bottling equipment
- Sliding components
- Food-processing machinery
Viscosity should be selected according to the required lubrication performance and application method.
2. Mold Release Agent
Potential applications include:
- Baking molds
- Food-processing molds
- Baking trays
- Confectionery equipment
- Plastic processing surfaces
- Rubber processing surfaces
Lower-viscosity grades generally provide easier spreading, while higher-viscosity grades can provide greater film retention.
3. Defoamer and Antifoam
Potential applications include:
- Food processing
- Fermentation
- Sugar processing
- Beverage processing
- Edible oil processing
The appropriate silicone format depends on the system. Some applications use PDMS fluid directly, while aqueous systems may require a formulated silicone emulsion.
For direct food applications, permitted use and dosage must be verified for the specific product and market.
4. Food Packaging and Processing Equipment
- Lubricants
- Release agents
- Surface treatment fluids
- Processing aids
How to Choose Food Grade Silicone Oil Viscosity?
| Viscosity | General Characteristics | Typical Application |
|---|---|---|
| 100–200 cSt | High flowability, easy spreading | Thin-film lubrication, surface treatment |
| 350–750 cSt | Balanced flow and film retention | Lubrication, release, processing |
| 1,000–1,500 cSt | Higher viscosity and film persistence | Persistent lubrication, release |
The exact viscosity should be selected according to equipment design, application method, operating temperature, required film thickness, and processing conditions.
350 cSt is an important medium-viscosity grade because it provides a practical balance between flowability and film retention. Silico® currently supplies food-grade PDMS 350 cSt for selected food-processing applications.Packaging and Storage

Frequently Asked Questions
Food grade silicone oil is a high-purity silicone fluid, typically based on PDMS (polydimethylsiloxane), intended for specific food-processing, food-contact, lubrication, mold-release, defoaming, and processing-aid applications where applicable regulatory requirements are met. Its suitability depends on the specific grade and intended use.
Silico® Food Grade Silicone Oil / Silicone Fluid is available in viscosity grades from 100 to 1,500 cSt at 25°C. This range covers applications requiring different levels of flowability, spreading, lubrication, and film retention.
350 cSt food grade silicone oil provides a balance between flowability and film retention. Based on the specific formulation and approved application, it can be used for food-processing lubrication, mold release, foam control, and selected processing-aid applications.
1,000 cSt food grade silicone oil provides higher viscosity and generally greater film retention than lower-viscosity grades. It can be considered for selected lubrication, mold release, surface treatment, and processing applications where a more persistent silicone film is required.
Food grade silicone oil is not automatically approved for every direct food-contact application. Suitability depends on the specific product grade, concentration, food type, temperature, contact conditions, intended use, and applicable regulations in the target market.
Yes, selected PDMS silicone fluids can be used for foam control in certain food-processing applications. The permitted use, concentration, and processing conditions must be confirmed for the specific grade and applicable regulatory requirements.
Lower-viscosity grades such as 100 cSt generally provide easier flow and spreading, while higher-viscosity grades such as 1,000 cSt provide greater film retention. The appropriate viscosity depends on the equipment, application method, operating temperature, required lubrication or release performance, and desired film characteristics.
For commercial evaluation, buyers should request the Technical Data Sheet (TDS), Safety Data Sheet (SDS), Certificate of Analysis (CoA), applicable food-contact or regulatory compliance documentation, and relevant certifications for the exact silicone oil grade and viscosity being supplied.
