  • This is a good callout, and it is true that most hand sanitizers are not effective against norovirus.

    However, at the risk of sounding like an advertiser which is not my intent, there are some higher grade sanitizers out there that do kill norovirus. One is called “Prime Defense” and was originally developed for cruise ships and restaurants where norovirus outbreaks are a major concern. Companies are not allowed to advertise kill of specific pathogens like norovirus for products regulated by the FDA, hence why it is not advertised as killing norovirus (hand sanitizer is an over-the-counter drug regulated by FDA).

    Washing your hands properly with soap and water is still an effective way to reduce risk of norovirus.








  • This article is talking about benzene, not benzine FYI.

    The allowable limit in drinking water by the EPA is 5 ppb. Inhalation exposure limit by OSHA is 1 a 5 ppm per day (inhalation is not an apples to apples comparison to consumption though). I’m not a toxicologist so I don’t know what exposure amount is “safe”, but dosage does matter.

    This article mentions benzene coming from the carbomer in these formulas. The benzene is a residual impurity in the carbomer making process, and there are carbomer on the marketplace that don’t use benzene in their manufacturing process, but they are more expensive. I’m not sure the source of carbomer for these products, but I’ve seen reported on carbomer I’ve looked at to have up to 1 ppm of benzene impurity. Products like this might use carbomer up to 0.5 to 1%. So you’d expect maximum levels of benzene to be in the product (at the aforementioned levels) to be 10 ppb. So possibly at double the amount allowable in drinking water by EPA. People drink a lot more water than cough syrup (I hope) so it might not be that concerning.

    The article frustratingly does not give amounts of benzene found in these products so it could be sensationalist—I just don’t know. So is benzene bad—yes. Does the cough syrup have concerning levels of benzene? Maybe, but just saying benzene might be present isn’t enough information in my opinion.
