Hand sanitizer manufacturers rely on INEGI to detect hazardous substances

06 August 2021
Hand sanitizers, widely known as alcohol-gel, have become part of everyone's routine, becoming a commonly consumed product. The control and quality assurance of these products is, therefore, vital to ensure everyone's safety.

INEGI is therefore able to carry out analysis of hand sanitizers, to detect dangerous substances, such as benzene, methanol or others. Through GC/MS analysis it is possible to identify hundreds of substances, some of which may be inadvertently present in the final products.

Supported by the Indoor Air Quality Laboratory, INEGI thus helps hand sanitizer manufacturers to ensure that their products comply with national and international regulations, without any danger to the health of their users.

This analysis is relevant as cases of contamination have already been detected. An American laboratory – Valisure1 – analyzed 260 samples from 168 different brands and found that 17% of the samples contained detectable levels of benzene. 21 samples (8%) contained benzene above two parts per million (ppm), a temporary limit that the US Food and Drug Administration (FDA) regulator has set for liquid hand sanitizers. Also, on the website of the European Commission for product safety, you can find several warnings about the presence of methanol, a very toxic substance, in hand sanitizers.

"These products were and continue to be of great importance in combating the pandemic, blocking transmission pathways and thus preventing the spread of the SARS-CoV-2 and other viruses. It is therefore of great importance that these products do not contain dangerous substances for health, which can be present due to the inadvertent use of contaminated reagents”, stresses Gabriela Ventura, a researcher at INEGI.
