This seems suggestive... isn't it likely that some of the contaminants they let slide were more combustible?
> On March 20, the US Food and Drug Administration announced that it was relaxing its regulations on hand sanitizer to “provide flexibility to help meet demand during this outbreak.” Those regulations, known as the Current Good Manufacturing Practices, had been in place since 1994 and included regularly updated rules on everything from record-keeping to product testing to packaging. The agency also paused the requirement under the Federal Food Drug & Cosmetics Act that sanitizer be sourced from pharmaceutical-grade ethanol, which is free of industrial toxins that are commonly found in fuel-grade ethanol. Businesses were still expected to test their sanitizers for benzene and other toxic compounds, but essentially on an honor system. The FDA noted that it did “not intend to take action against firms” for violations during the public health emergency.

> By mid-June the FDA had received so many complaints that it started compiling an online list of “hand sanitizers consumers should not use.” Because the agency does not have recall authority for over-the-counter drugs, the offending companies themselves were expected to pull products marked as unsafe. Consumers had to go out of their way to find the list and stay up to date as it got longer and longer. By the end of that first pandemic summer, nearly 200 types of sanitizer appeared on the list.
> ArtNaturals was, at that point, not on the list. Its sanitizer, labeled with a tasteful, millennial-friendly design that said it was vegan and infused with jojoba oil, was marketed as “safe for kids” and “a great bulk hand sanitizer pack for parents and teachers.” At least two school districts on the West Coast had purchased the sanitizer to distribute to students, in addition to two Ivy League universities. Then, in March 2021, a year into sales, an independent lab in Connecticut called Valisure announced that it had found benzene in the company’s sanitizer. Benzene, a widely used industrial chemical derived from petroleum, can be absorbed through the skin and is known to be a risk factor for leukemia.
Then again, intentional destruction is certainly a possibility too.
