Introduction

A basic chemical compound consisting of Hydrogen, Oxygen, and Carbon is formaldehyde. As part of cell metabolism, all life forms - bacteria, fungi, fish, animals, and humans, spontaneously contain formaldehyde.

Formaldehyde is perhaps better known for its preservative and anti-bacterial qualities, but many value-added products are produced using formaldehyde-based chemistry. Formaldehyde is one of the most well-studied and well-understood chemicals.

Uses & Advantages

In developing hundreds of products that enrich daily life, formaldehyde is an essential building block chemical. In the final goods which customers use, few, if any, formaldehyde remains.

Design and Construction

Formaldehyde-based resins are used widely in cabinetry, countertops, moldings, cabinets, shelving, stair systems, flooring, wall sheathing, support beams, and trusses many other home furnishings and structures to create composite and fabricated wood products.

Health Care Uses

Formaldehyde has a long tradition of safe use in the manufacturing of hard-gel tablets, vaccines, and anti-infective medicines.

Personal care and consumer goods

Chemistry dependent on formaldehyde is vital for the manufacture of much personal care and consumer products.

Automobiles

The technology of formaldehyde helps make automobiles lighter and more energy-efficient. Resins based on formaldehyde are used to render interior molded parts and components under the hood that need to withstand high temperatures.

Use of formaldehyde in diet and other uses

It is used in fruit, painting, and cosmetics as a preservative. Formaldehyde is also used in pharmacy as an antiseptic, funeral home disinfectant. It is also used to produce RDX. It is used in the petroleum and natural gas industry to increase fuel yields. It is used in the processing of ink as well.

Illustrated Examples

1. Does formaldehyde eliminate baking soda?

Answer: It is often made more flammable by formaldehyde in clothes, which can cause contact dermatitis. Chemical preparation can be removed by cleaning. Baking soda absorbs any of it but does not neutralize it. In liquids, formaldehyde is easily soluble.

2. In hospitals, what is formaldehyde used for?

Answer: Formaldehyde is used as a disinfectant in laboratories both as an anatomical specimen fixative and preservative. 

3. Does formaldehyde have color and odor?

Answer: Formaldehyde is a colorless compound that is widely used in many industrial processes with a potent pickle-like odor.

FAQs on Uses of formaldehyde

Q: Why is formaldehyde used?

A:  Formaldehyde is widely used in mortuaries and medical labs as an agricultural fungicide, germicide, disinfectant, and preservative. Formaldehyde also occurs in the atmosphere naturally. Most living organisms produce it in small quantities as part of natural metabolic processes.

Q: What is the usage of a solution of formaldehyde?

A:  As a disinfectant, an aqueous formaldehyde solution may be beneficial as it destroys both bacteria and fungi (including their spores). It is used to inactivate contaminants and pathogens as an additive in vaccine production. In personal care products, such as cosmetics, formaldehyde releasers are used as biocides.

Q: Is formaldehyde used as a disinfectant?

A:  In both its liquid and gaseous forms, formaldehyde is used as a disinfectant and a sterilizer. Formaldehyde absorption can be lethal, and long-term exposure to low amounts in the air or on the skin, such as dermatitis and itching, can cause asthma-like breathing symptoms and skin discomfort.

Q: What foods are formaldehyde-containing?

A:  Formaldehyde can naturally be present in foods with a concentration of up to 300 to 400 mg/kg, including fruit and vegetables (e.g.: pear, apple, green onion), beef, fish (e.g.: Bombay duck, cod), crustaceans, dried mushrooms, etc.

Q: What is another name of formaldehyde?

A:  Formaldehyde can be labeled with other names on the product label, such as Formalin, Aldehyde formic, Of methanediol.
