Content: 99% min
Packing: 25kgs per bag

As a strong chemical base, guanidine carbonate is used as an intermediary in a broad range of application fields, including:

  • Chemicals
    • production of guanidine nitrate
    • flame retardant in technical textiles
  • Cosmetics – hair relaxer that straightens hair by chemically uncurling it
  • Detergents – synergistic agent
  • Pharmaceuticals – antibiotics
  • Microencapsulation process – for carbonless paper

Guanidine Carbonate is an alkaline, organic salt utilized primarily as an ingredient in hair straightening and depilatory systems. When combined with calcium hydroxide in (no-lye) hair relaxers it reacts to form a less irritating system than sodium hydroxide-based (lye) systems. It also is used as a buffering agent and a pH adjuster.

Guanidine Carbonate supplied by BariteWorld has a minimum purity of 99.0 percent.
