Scientists at LGC have developed a new method for the determination of formaldehyde in food contact materials. They are confident that this method can also be applied to cosmetic products.
One area where there is concern about formaldehyde, which is both a toxin and an allergen) is in hair-straightening products. It is added as methylene glycol in these products, which hydrolyses to give formaldehyde when heated in use. The formaldehyde released under these conditions may exceed the permitted level, but producers can argue that they have not added formaldehyde to their products.
Does legislation need amending to cover methylene glycol as it can be considered to be incipient formaldehyde?
