formaldehydecontaining

Formaldehyde-containing refers to materials or products that include formaldehyde or are capable of releasing formaldehyde under normal use. The term covers substances where formaldehyde is part of a polymer resin or present as a residual or bound chemical, and also materials that off-gas formaldehyde over time. It is used to distinguish such products from those marketed as formaldehyde-free or low-emission.

Common sources include wood-based panels such as particleboard, medium-density fiberboard, and plywood bonded with urea-formaldehyde or related resins; textiles treated with formaldehyde-based resins to improve wrinkle resistance; certain coatings, adhesives, foams, and insulation materials; and some cosmetics or household products that historically used formaldehyde-releasing preservatives.

Health and safety considerations are central to the formaldehyde-containing category. Formaldehyde can irritate the eyes, nose, and throat and may provoke respiratory symptoms with prolonged exposure. It is classified by many health agencies as a human carcinogen, and regulatory limits on occupational exposure exist in many countries. Consumer product emissions are often subject to standards intended to limit indoor concentrations. Emission levels are influenced by product formulation, environmental conditions, and ventilation.

Mitigation and alternatives focus on reducing exposure. Consumers can choose formaldehyde-free or low-emission products and seek third-party certifications. Adequate ventilation helps manage indoor levels. In regulation, standards such as those governing composite wood products (for example, CARB Phase 2) set explicit emission limits to minimize formaldehyde release. Detection and measurement typically involve air sampling and chromatographic analysis.
