Does sponge contain formaldehyde

Sponges are a material that absorbs water very well. Since sponges are porous, they can be used to clean items. There are many types of sponges, such as chemical sponges and industrial sponges. Many people are very afraid that sponges contain formaldehyde. Formaldehyde is very irritating to human skin and can also combine with protein. After the human body absorbs a large amount of it, it will induce headaches. So does sponge contain formaldehyde?

First, does sponge contain formaldehyde? Sponge is a polymer material and does not contain formaldehyde. Definition of formaldehyde. Formaldehyde is a colorless gas with a strong irritating odor. It is easily soluble in water and appears in the form of aqueous solution. Soluble in water, ethanol, alcohol and ether. Formaldehyde is an important organic raw material, mainly used in the plastics industry (such as phenolic resin, urea-formaldehyde plastic - electroplating), synthetic fibers (such as synthetic vinylon - polyvinyl formal), leather industry, medicine, dyes, etc.

Second, the hazards of formaldehyde: 1. Irritating effect on skin and mucous membranes. Formaldehyde is a protoplasmic toxic substance that can combine with protein. When inhaled in high concentrations, it can cause severe respiratory irritation and edema, eye irritation, and headaches. 2 Sensitization effect: Direct contact of skin with formaldehyde can cause allergic dermatitis, pigmentation, and necrosis. Inhalation of high concentrations of formaldehyde can induce bronchial asthma. 3 Mutagenic effect High concentration of formaldehyde is also a genotoxic substance. Experimental animals may develop nasopharyngeal tumors if they inhale high concentrations in the laboratory. 4. Prominent symptoms include headache, dizziness, fatigue, nausea, vomiting, chest tightness, eye pain, sore throat, poor appetite, palpitations, insomnia, weight loss, memory loss and autonomic nervous system disorders; long-term inhalation by pregnant women may cause fetal malformation or even death, and long-term inhalation by men may cause sperm malformation and death.

Does the sponge contain formaldehyde? No, it does have some smell if you buy it newly, but it will go away after a while. The odor of the sponge is probably because the sponge is put into production without being completely dry. Normally, the sponge factory should dry it in the shade for 7 days before supplying it to the manufacturer. The manufacturer also needs to air dry it naturally for a week before cutting and production. After production, the sponge needs to be ventilated for 2-3 days before it can be supplied to the merchant. This is the normal process for soft furniture. If the smell is very strong and has a foul odor, then there is probably something wrong with the quality of the sponge. Put the sponge product in a ventilated place for a few days and it will get better.
