· It’s free from things like flame retardants, formaldehyde, and other toxic chemicals, and instead, they use water-based, low-VOC glues and stains as much as possible. They also use soy-based foam for their cushions, instead of polyurethane foam, which is a petroleum product that tends to have more chemical emissions.
· Since wood naturally contains formaldehyde, it cannot be called formaldehyde-free, technically. No Added Formaldehyde implies that the formaldehyde emission is less than 0.04 ppm. The natural level of formaldehyde in wood is about 0.01 ppm. MDF looks very similar to HDF (high density fiberboard, hardboard) which is practically the same …
· Foam materials can be used as building and packaging materials because of their advantages such as lightweight, heat insulation, flame retardancy, sound insulation, and shock absorption [1,2,3,4].However, the oil-derived foams on the market, such as polyurethane (PU) [5,6] and polystyrene (PS) [7,8], are nonrenewable materials that …
Formaldehyde-releasing chemicals are used as flame-retardants and to provide crease resistance in textiles and as a binder in textile printing. Durable-press or permanent-press resins containing formaldehyde have been used in cotton and cotton-polyester fabrics since the mid-1920s to minimise wrinkles during wear and laundering.
CAS No. 50-00-0. Formaldehyde (CH₂O) is a colorless, highly toxic, and flammable gas at room temperature. It is used in the production of fertilizer, paper, plywood, and some resins. It is also used as a food preservative and in household products, such as antiseptics, medicines, and cosmetics. Exposure to formaldehyde can irritate the skin ...

Formaldehyde is widely used in many consumer products, including building materials, pressed wood, cosmetics, shoe-care products, and textiles. It is also used as a disinfectant and as a preservative, including in mortuaries and medical labs. It has been identified as a cause of leukemia and nose and throat cancer, and linked to asthma and skin ...
· Add a cup of white vinegar to your rinse cycle to help wash out formaldehyde better. Add borax to the laundry. Ah, borax, the solution to pretty much everything in the laundry room, even formaldehyde in clothes! Add one cup of borax at the beginning of the load, with your usual detergent.
