Is Nano Sponge (Melamine Foam) Harmful to the Human Body when Used for Cleaning?

Nano sponge is also called cleaning sponge\magic sponge\magic wipe, and the technical term is Melamine Foam. It is very effective for cleaning household stainless steel products, bathroom products, glass products, tiles and porcelain, leather sofas, cars, tables and chairs, wooden floors and other things. When cleaning, you only need to use water to quickly remove stains, so it is quickly familiar to everyone.

However, there are reports that the raw material of nano sponge is melamine. Will this be harmful to the human body? The main reason why people have doubts is the impact of the melamine-tainted milk powder incident.

Compared with melamine, more and more people are paying attention to the formaldehyde release of magic wipes. Here we will explain it to you in detail.

1. According to the "Hygienic Standards for Formaldehyde in Bedroom Air", the maximum allowable concentration of formaldehyde in bedroom air is 0.08 mg/cubic meter. Put the nano sponge into a large closed beaker to measure the formaldehyde concentration. According to this measurement method, all the home decoration materials placed in it will probably exceed the standard. It should be noted that the formaldehyde concentration measured is the formaldehyde concentration in the indoor air, not the formaldehyde concentration measured by placing purchased decorations in a small sealed box.

2. Formaldehyde is a substance that is easily soluble in water and chemically unstable. It dissipates before it can be enriched. Compared with the convenience brought by nano sponge and the disadvantages of many cleaning tools before it (nano sponge is not easy to get moldy, people who have used it should have noticed that stainless steel wire is more harmful to tableware. Ordinary sponges are very susceptible to mold growth, and ordinary rags are even more fungus-centered).

3. When melamine resin is used as tableware, the country actually issued relevant standards as early as 1980. This standard has been revised twice and is currently GB9690-2009, which has requirements for the migration amount of formaldehyde. Although tableware and nano-sponge are different, they are both melamine and kitchen supplies. Before the national standard of nano-sponge is released, they can also be used for reference. According to this standard, it is determined whether the nano sponge meets the standard, instead of simply saying that it is unqualified if it releases formaldehyde. There are many things containing formaldehyde. As for the consequences, it is still subject to not exceeding the standard.

Where does the Nano Sponge’s excellent cleaning ability come from?

Due to its high hardness and brittleness, melamine-formaldehyde resin foam is brittle and can separate from the foam surface through friction and disperse into fine particles. When wiping stains, these fine particles shed from the foam surface form effective friction with stubborn stains, wiping the stains off and effectively adsorbing them into the pores of the foam. Therefore, this resin foam dry wipe also has great cleaning capabilities.

Melamine formaldehyde resin foam has an open three-dimensional network porous structure, and the cell structure is thin and good. These tiny porous network structures easily absorb moisture and show hydrophilicity, so the adsorption performance is excellent. The excellent adsorption performance of this microporous structure also has a good cleaning effect on stains on scratches on the surface of objects.

Moreover, the nano sponge itself has good physical stability, does not melt in water, and is fireproof.

SINOYQX melamine foam is as hard as glass fiber reinforced plastic, but the fine cell structure provides the flexibility of the product. When melamine foam is moistened with water, surface dirt can be easily wiped off.
