Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If petroleum-based release agents >70% oil
High petroleum content penetrants/releasers go to the petroleum lubricant subheading.
If organic composite solvents with release properties
Solvent-based releasers without primary lubricant function classify as organic composites.
If spray-form metal cleaners with release additives
Cleaner/polish formulations with incidental release properties fall under scouring preparations.
