Glyoxal 40%-HOOCHEMTEC
Glyoxal Application Glyoxal (OCH-CHO) is the simplest dialdehyde. Its high reactivity, primarily due to its two aldehyde functional groups, makes it a valuable crosslinking agent and chemical intermediate across a wide range of industries. Its core function is to form stable bonds with molecules containing hydroxyl (-OH), amino (-NH₂), and other nucleophilic groups, thereby modifying the properties of materials.such as improving durability, anti-wrinkle property, insolubility, hardness, etc. Here are the key application areas, broken down by industry: 1. Textile Industry (Largest Application) Glyoxal's primary use is in the textile finishing sector, specifically for producing Durable Press (DP) or "wash-and-wear" cotton fabrics. Role: It is the key component in the synthesis of Dimethyloldihydroxyethyleneurea (DMDHEU), the most common reactant resin used for permanent press finishing. Mechanism: The glyoxal-based resin crosslinks the cellulose chains of cotton fibers during a curing process. This crosslinking "locks" the fibers in place. Benefits: Wrinkle Resistance: Provides excellent crease recovery and smoothness after washing. Dimensional Stability: Prevents fabric from shrinking. Improved Durability: Enhances the fabric's tensile strength and abrasion resistance. 2. Paper Industry Glyoxal is used as a wet-strength resin and a retention aid. Wet-Strength Agent: Glyoxalated polyacrylamide (GPAM) resins crosslink the cellulose fibers in paper. This creates a network that maintains its strength when wet, which is crucial for products like: Towels and paper napkins Tea bags and coffee filters Map paper and packaging materials Retention and Drainage Aid: It helps bind fine particles and fillers to the paper fibers, improving paper formation, reducing effluent load, and increasing water drainage rates on the paper machine. 3. Personal Care & Cosmetics In this sector, glyoxal acts as a crosslinking agent for modifying polymers. Primary Use: Crosslinking Polyvinyl Alcohol (PVA) to create a gelling agent used as a thickener in toothpaste. This provides the desired rheology and stability. Hair Styling: Used in some hair spray formulations to provide a strong, long-lasting hold by crosslinking polymers that coat the hair. (Note: Its use in cosmetics is highly regulated due to potential sensitization, and concentrations are kept very low). 4. Leather Industry Role: Used as a tanning agent and retanning agent. Mechanism: Its aldehyde groups react with the amino groups in collagen proteins in hide. Benefits: Imparts a soft, full handle to leather. It is particularly valued for producing white leather (as it doesn't cause discoloration) and for enhancing properties like washability, perspiration resistance, and lightfastness. 5. Adhesives and Sealants Role: Functions as a crosslinker for water-based polymers containing hydroxyl groups, such as Polyvinyl Acetate (PVA) and starch-based adhesives. Benefits: Significantly improves water resistance, heat resistance, and initial tack of the adhesive. This is critical for applications in: Woodworking (e.g., plywood manufacturing) Packaging and labeling Construction materials 6. Organic Synthesis & Pharmaceutical Intermediates This is a fundamental and growing application. Glyoxal is a key building block for synthesizing more complex molecules. Pharmaceuticals: It is a crucial intermediate in the production of several important drugs, including: Antibiotics (e.g., Amoxicillin) Sartans (Angiotensin II Receptor Blockers - ARBs) for hypertension (e.g., Valsartan, Irbesartan). Agrochemicals: Used in the synthesis of certain herbicides and insecticides. Other Chemicals: Serves as a precursor for imidazoles, glyoxylic acid, heterocyclic compounds, and various flavors and fragrances. 7. Disinfection and Biocides Role: Glyoxal possesses inherent biocidal properties. Use: It is employed as an active ingredient in disinfectants and sanitizers for hard surfaces in institutional, industrial, and agricultural settings (e.g., animal housing). It is often formulated with other actives like Quaternary Ammonium Compounds (Quats). It is valued for being less volatile and having a less pungent odor than formaldehyde. 8. Oil and Gas Industry Role: Used as a scavenger for hydrogen sulfide (H₂S) in drilling fluids and production streams. It reacts with H₂S to form non-hazardous compounds, mitigating corrosion and safety risks. If you want to know more about the Glyoxal product ,can contact with HOO CHEMTEC freely.Thanks!
