DMHF is a preservative that slowly releases formaldehyde to kill bacteria in water-based personal-care products.
It extends shelf life cheaply by releasing low levels of formaldehyde over time.
Formaldehyde is a known human carcinogen and a common skin sensitizer. The EU restricts formaldehyde-releasing preservatives and requires warning labels; Washington State is phasing them out, while they remain unrestricted federally in the US.
