formalin are often used interchangeably, but there are important differences in their concentrations. A fixative labeled 10% buffered formalin is actually a 4% solution of formaldehyde (i.e., a 10% solution made from a 37-40% solution of formaldehyde). Symptoms of Exposure Because formaldehyde is very water soluble it affects the mucous membranes.
