Sodium glucoheptonate (H-Quest A300)

  • CAS No.- 13007-85-7
  • INCI.- Sodium Gluceptate

Sodium Gluceptate (H-Quest A300) is a natural chelating agent produced from high purity sugar and is inherently biodegradable. Sodium Gluceptate is a replacement for traditional chelate such as EDTA and exhibit excellent natural sequestration power over a broad range of di- and tri-valent metal ions, (Ca2+, Mg2+, Fe2+, Fe3+, Zn2+, Al3+).

Sodium Gluceptate is highly compatible with strong alkali solutions (pH 8.00-10.00), which can prevent the bacterial and fungal degradation of the solution. Unlike EDTA and NTA based chelating agents, Sodium Gluceptate is a non-toxic, non-hazardous, non-corrosive product and therefore a much safer compound. Typically, a dosage level of 0.1% to 0.3% is used as a starting point

Sodium gluceptate is a high-performance chelating agent. Its superior performance in the pH range between 12 and 14 is due to its efficiency in forming stable chelates with di- and tri-valent metal ions such as Ca2+, Mg2+, Fe2+, Fe3+, Zn2+, Mn2+, etc. In the chart below comparative data is reported at different pH levels with the most common chelating agents present on the market:

• Can be used in ECOCERT/COSMOS formulations
• Easy to handle
• Good efficacy against molds and bacteria
• Safe profile
• approved for use in leave-on and rinse-off products
• efficacy at low concentration
