The Donald Trump administration said this week it will temporarily allow some impurities in alcohol-based hand sanitiser to ensure access to the product during the coronavirus pandemic, reversing course after having tightened restrictions in April.
The move will provide clarity on impurity limits for a slew of fuel ethanol companies that had switched to producing hand sanitiser during the outbreak, after regulators discovered some of the impurities, including cancer-causing acetaldehyde, several weeks ago.
"We are specifying interim levels of certain impurities that we have determined can be tolerated for a relatively short period of time," the FDA said on its website.
"We believe that our temporary guidances sets the proper level of flexibility at the current time to help protect Americans during this public health emergency."
The new FDA guidance allows up to 2 parts per million of benzene and 50 ppm of acetaldehyde, according to the web site.
The ethanol industry invested millions of dollars since March to ramp up the output of corn-based alcohol sanitiser at a time when fuel demand has slumped from the pandemic. Twenty-seven plants are currently producing ethanol for sanitizer, the Renewable Fuels Association said.
RFA President Geoff Cooper said the limits are overly restrictive.
"We do not believe the new guidance will help alleviate the hand sanitizer shortage in any meaningful way," Cooper said.
