Polyether detergents can accumulate peroxides. The ferrous oxidation in Xylenol orange (FOX) assay effectively screens for this, and antioxidants prevent peroxide buildup in detergents.

Area of Science:

  • Chemical analysis
  • Biochemistry

Background:

  • Polyether detergents are prone to peroxide accumulation.
  • The kinetics and conditions of this accumulation are not well understood.

Purpose of the Study:

  • To establish the ferrous oxidation in Xylenol orange (FOX) assay as a method for screening detergent peroxide accumulation.
  • To investigate the mechanisms of peroxide accumulation in detergents.

Main Methods:

  • Utilized the FOX assay to monitor peroxide levels in polyether detergents.
  • Tested the efficacy of a chain-breaking antioxidant and a metal-chelating agent in preventing peroxide accumulation.

Main Results:

  • The FOX assay proved effective for screening detergent peroxide accumulation.

  • A chain-breaking antioxidant successfully blocked peroxide accumulation.
  • A metal-chelating agent did not prevent peroxide accumulation under the tested conditions.

    • Conclusions:

    • The FOX assay is a valuable tool for assessing peroxide accumulation in detergents.
    • Antioxidants can inhibit peroxide formation in polyether detergents stored under light and room temperature conditions.
