formaldehyde means the colorless, flammable carcinogenic chemical, an organic compound with the formula HCHO, which is used in the manufacture of building materials (e.g., pressed wood products) and household products. Federal limits for formaldehyde emissions from building materials (hardwood plywood, medium-density fiberboard, and particleboard) were established in 15
formaldehyde. For garments worn directly against the skin, formaldehyde content in the fabric must be less than 75 p.p.m. when tested by the Acetylacetone method in accordance with Japanese law 112. For garments in sizes up to and including 4T (Toddler), formaldehyde content in the fabric must be less than 20 p.p.m. regardless of whether they are worn directly or indirectly against the skin. For other garments, formaldehyde content in the fabric must be less than 300 p.p.m.;
