What is Glyoxal?
Glyoxal (CAS 107-22-2), also known as oxal, is a dialdehyde compound used industrially as a crosslinking agent, biocide, and chemical intermediate.
Where is Glyoxal used?
- Textile and paper: crosslinks cellulose fibers for wrinkle resistance and wet strength
- Leather processing: tanning auxiliary and fixative that improves fiber structure and dimensional stability in hides
- Water treatment: biocide active controlling microbial growth in industrial cooling systems
- Printing and packaging: binder crosslinker in coatings, improving water resistance and ink adhesion on paper and board
- Its reactivity with hydroxyl, amine, and amide groups insolubilizes and stabilizes substrates in wet and dry processing.
