Bis-aminopropyl diglycol dimaleate

Bis-aminopropyl diglycol dimaleate (CAS 1629579-82-3) is a specialty diamine crosslinker used in personal care formulations to modify and strengthen hair fiber surfaces. By forming covalent bonds with keratin proteins, it improves the structural integrity of chemically treated or damaged hair. It is primarily used in bond-building hair treatments and salon-grade repair systems.

The compound works alongside bleaching or coloring processes to reduce breakage and improve elasticity. In leave-on and rinse-off conditioning formulations, it deposits onto the hair shaft to reinforce weakened disulfide bonds. Retail bond-repair product lines, including pre-treatment boosters and in-salon additives, rely on this ingredient to deliver measurable improvements in tensile strength for various hair types.

It is also incorporated into at-home treatment masks and serums targeting chemically processed or heat-damaged hair. This versatile ingredient ensures long-lasting results for professional hair care applications. Bis-aminopropyl diglycol dimaleate is supplied as a liquid, typically as an aqueous solution. It is available in cosmetic-grade quality suitable for direct incorporation into personal care formulations.

Packaging options generally range from small quantities for R&D use to bulk drums for commercial manufacturing. This ensures flexibility for both boutique laboratories and large-scale production facilities.
