Hand Sanitizer Testing and Analysis


Due to the public health emergency caused by the Coronavirus Pandemic, the FDA is allowing companies to manufacture alcohol-based hand sanitizers for consumer use and for use as health care personnel hand rubs for the duration of the public health emergency.

However, the based on GLP Guidelines, hand sanitizers must be manufactured using only United States Pharmacopeia (USP) grade ingredients that are consistent with World Health Organization (WHO) recommendations. The USP ingredients include:

  • Alcohol (ethanol) (USP or Food Chemical Codex (FCC) grade) (80%,volume/volume (v/v)
    • In an aqueous solution or Isopropyl Alcohol (75%,v/v) in an aqueous solution.
  • Glycerol (1.45% v/v)
  • Hydrogen peroxide (0.125% v/v)
  • Sterile distilled water or boiled cold water

Hand sanitizer is a critical aspect in our fight against the spread of the Coronavirus. Clark Laboratories offers testing and analytical services to verify the ingredients and purity of hand sanitizer products.


It is widely accepted that contaminated anti-bacterial products can undermine the sterilizing effects of hand sanitizers. Clark’s Analytical Chemistry lab can provide the critical analysis of the hand sanitizer ingredients and will affirm that the manufacturers ingredients are within the USP guidelines and meet the intended anti-bacterial functions.
