Vegetable Oil Methyl Esters (VOME) or Fatty Acid Methyl Esters (FAME) are fatty acid esters produced by transesterification of vegetable oils with methanol. The reaction by-product is glycerin. The main sources of vegetable oils are castor oil, rapeseed, soybean, and sunflower. They are considered bio-based alternatives to petroleum solvents (agro-solvents) with good solvent power (KB>65). The different grades of vegetable oil methyl esters differ in the chain length distribution of the fatty acids in the vegetable oils. They are fluid, oily, low-volatility products, not classified as hazardous, and readily biodegradable.
This grade of bio-based methyl esters is based on a majority of C18 fatty acids (methyl stearate, oleate, linoleate, ricinoleate>75%) and is derived from sustainable, non-GMO castor oil production.
Applications include:
- Biofuel
- Concrete release agent
- Solvent for agrochemical preparations
- Bio-based plasticizer for coatings and adhesives
- Sustainable alternative to mineral oils for numerous industrial applications
- Lubricant additive for metalworking (cutting/neat oils)
- Wetting agent in metalworking fluids
- Leather treatment agent
- Degreasing agent, tar remover
- Bitumen fluxing (flux agent, lowers bitumen working temperature)
- Printing (offset ink formulation agent)
Advantages:
- Used as a 95% bio-based, sustainable, and carbon-neutral fluid
- High solvent power (Kauri-Butanol index KB>65)
- Readily biodegradable
- High flash point, high boiling point
- Free of heavy metals and PAHs
- Good lubrication properties
- Sustainable alternative to mineral oils for numerous industrial applications
- HLB = approx. 11
- Not classified as hazardous
