ASTM Standard to measure effectiveness of hand sanitizers.
Press Release Summary:
With outbreaks of H1N1 influenza this year, ASTM International Committee E35 on Pesticides and Alternative Control Agents is developing proposed standard that will measure antibacterial activity of hand sanitizers on people's hands. According to David Macinga, microbiology principal scientist, GOJO Industries Inc., ASTM WK23789 accurately reflects typical use pattern for hand sanitizers and produces results that are reflective of real-world efficacy of these products.
Original Press Release:
Proposed New ASTM Standard to Measure Effectiveness of Hand Sanitizers
W. CONSHOHOCKEN, Pa., 3 June 2009-Outbreaks of the H1N1 influenza this year have increased the public's awareness and use of leave-on hand antiseptics, popularly known as hand sanitizers. ASTM International Committee E35 on Pesticides and Alternative Control Agents is now developing a proposed new standard that will measure the antibacterial activity of hand sanitizers on people's hands. ASTM WK23789, Test Method for Evaluation of the Effectiveness of Leave-On Health Care Personnel Handwash Formulations, is under the jurisdiction of Subcommittee E35.15 on Antimicrobial Agents.
David Macinga, microbiology principal scientist, GOJO Industries Inc., and leader of the ASTM WK23789 task group, notes that hand sanitizers are currently evaluated using ASTM E1174, Test Method for Evaluation of the Effectiveness of Health Care Personnel Handwash Formulations. However, ASTM E1174 was designed to evaluate rinse-off antimicrobial soaps.
"ASTM WK23789 is useful in that it more accurately reflects the typical use pattern for hand sanitizers and is simpler to perform than the test in ASTM E1174," says Macinga. "The proposed new standard also produces results that are reflective of the real-world efficacy of these products."
In addition to use by companies developing and/or marketing leave-on hand antiseptic products, ASTM WK23789 will have applications for academic and clinical researchers interested in topical antiseptics.
All interested parties are invited to participate in the ongoing development of ASTM WK23789. For technical information, contact David Macinga, GOJO Industries Inc., Akron, Ohio (phone: 330-255-6292; macinga@gojo.com). ASTM Committee E35 meets Oct. 19-22 during October committee week in Atlanta, Ga.
