Soybean Methyl Ester (SME) & Canola Methyl Ester (CME)

We’re here to answer your questions and provide assistance

Characteristics and Properties of SME and CME

Soybean Methyl Ester (SME) and Canola Methyl Ester (CME) are renewable, biodegradable methyl esters derived from the transesterification of soybean and canola oils. These eco-friendly solvents offer numerous advantages over synthetic alternatives. Key properties include:

  • Biodegradability: SME and CME break down naturally, making them environmentally safe and reducing ecological impact.
  • Low Toxicity: Non-hazardous to humans and animals, suitable for use in sensitive applications like personal care and food processing.
  • High Solvency: Both esters exhibit excellent solvency, effectively dissolving a wide range of resins, oils, and greases.
  • Thermal Stability: With high flash points and low volatility, SME and CME offer safety and performance in industrial settings.
  • Compatibility: They are compatible with a broad spectrum of other ingredients, facilitating their incorporation into diverse formulations.

Industrial Applications of SME and CME

SME and CME are gaining widespread adoption across industries due to their versatility and sustainability:

1. Coatings and Paints

  • Serve as effective solvents and coalescing agents in waterborne and solvent-based coatings.
  • Enhance film-forming properties and improve the durability of paints, varnishes, and lacquers.
  • Reduce VOC emissions, making them compliant with strict environmental regulations.

2. Personal Care Products

  • Act as emollients and carriers in formulations for lotions, creams, and cleansers.
  • Provide mild and non-irritating solvent properties for makeup removers and other skin-friendly products.
  • Offer a plant-based alternative to petroleum-derived solvents in sustainable beauty products.

3. Cleaning and Degreasing

  • Used as green solvents in industrial and household cleaning products, including degreasers and stain removers.
  • Effective in removing heavy oils, adhesives, and residues from surfaces and equipment.
  • Provide a safer alternative to harsh chemical solvents in cleaning applications.

4. Adhesives and Sealants

  • SME and CME are used as processing aids in adhesive and sealant production, improving consistency and workability.
  • Enhance adhesive properties without compromising environmental safety.

5. Lubricants and Metalworking Fluids

  • Function as base oils or additives in biodegradable lubricants and cutting fluids.
  • Improve lubrication, reduce friction, and ensure biodegradability in metalworking applications.

6. Agriculture

  • Used as carriers in pesticide formulations and as adjuvants to enhance the efficacy of agrochemicals.
  • Biodegradable and safe for use in environmentally sensitive areas.

Packaging and Supply Options

SME and CME are available in a variety of packaging formats to meet different operational needs:

  • Bulk Supply: Cost-efficient options for high-volume industrial use.
  • ISO Tanks: Suitable for large-scale transportation and storage of methyl esters.
  • Intermediate Bulk Containers (IBCs): Convenient for medium-scale operations, offering secure and efficient handling.
  • Barrels: Ideal for smaller-scale applications or remote locations.

Environmental and Sustainability Benefits

SME and CME align with global sustainability goals, offering several environmental advantages:

  • Renewable Origin: Produced from plant oils, SME and CME reduce reliance on fossil fuels and promote circular economy practices.
  • Low Carbon Footprint: Their production and use generate significantly fewer greenhouse gas emissions compared to petroleum-based solvents.
  • Biodegradability: Quickly break down in natural environments, minimizing risks of soil and water contamination.
  • Reduced VOC Emissions: Help industries comply with stringent regulations by lowering volatile organic compound emissions.
