Ensure Hand Sanitizer Safety with Precision Testing for Harmful Aldehydes
Hand sanitizers are commonly formulated with 70% ethanol and/or isopropanol (IPA), along with additives such as glycerol and 1–2% hydrogen peroxide. However, the use of technical-grade ethanol, approved temporarily by Health Canada due to ethanol shortages, can introduce up to 1000 ppm of acetaldehyde. Additionally, hydrogen peroxide in these formulations reacts with organic components of the sanitizer, oxidizing alcohol into formaldehyde and acetaldehyde, which can further degrade into organic acids.
The Importance of Testing for Aldehyde Contamination
As aldehyde accumulation poses potential health risks to users, including front-line workers and healthcare professionals, accurate testing is crucial. LCS Laboratory provides analytical services to detect and quantify trace levels of formaldehyde and acetaldehyde, ensuring the safety and compliance of hand sanitizer formulations. Our testing supports manufacturers in maintaining product quality while protecting end-users from harmful exposure.
Our Analytical Procedure
LCS Laboratory employs a robust HPLC-UV method for aldehyde analysis. The procedure begins with catalytic neutralization of hydrogen peroxide to prevent interference. This is followed by derivatization of formaldehyde and acetaldehyde with 2,4-dinitrophenylhydrazine (DNPH), which enhances detection sensitivity. The analytical workflow is aligned with NIOSH Methods 2016 and 2018, ensuring accuracy and reliability in results.
Comprehensive Air Quality Testing
In addition to hand sanitizer analysis, we offer air quality testing for alcohols, formaldehyde, and acetaldehyde, helping protect front-line workers from occupational exposure. Our services are tailored to meet the needs of industrial hygiene consultants and health professionals.
