Is formaldehyde in Kling wipes, magic wipes, dishwashing wipes, and sponge wipes really harmful?

In my opinion, the following is true:

Regarding these eastern products, it is important to note that they should not adhere to the national standard and their materials may contain formaldehyde precursors. cellulose sponge cloth manufacturers If the manufacturing process does not meet the standard, there is a high chance of continued formaldehyde release, resulting in elevated levels within a certain radius. However, if the product is tested in a confined space and does not exceed the standard, this would only be considered a temporary solution and would not accurately reflect the true amount of formaldehyde present. It is common for similar products to emit some level of formaldehyde; what matters most is the rate and duration of this release. By following the method shown in the video, any related product could easily be deemed as exceeding the standard. After all, given enough time and a small enough space, formaldehyde can reach high concentrations. Using limited detection time and space as evidence for exceeding the standard is simply deceitful.

The usual purpose of these erasers is to clean dishes, chopsticks, or writing boards. Due to their limited contact with the human body, they do not typically cause any harm from formaldehyde absorption through the skin. However, when inhaled into the alveoli, formaldehyde can have toxic effects on the body. In the case of a lower quality eraser that is used for an extended period (such as when a teacher holds it in their hand), it may emit high levels of formaldehyde that can be harmful to the body.

The size and weight of the erasers are relatively small, resulting in a lower amount of formaldehyde precursors released. With proper ventilation in the area where they are placed, there should be no significant impact on indoor formaldehyde levels. However, low-quality home decorations often have larger sizes and release formaldehyde at a faster rate, which can pose a risk to human health by increasing indoor formaldehyde concentration.

Overall conclusion, if long-term contact (teachers) may cause some harm, short-term contact (washing dishes) will not cause harm, and these eraters are unlikely to be the main culprit of indoor air formaldehyde pollution, so we should be more concerned about ubiquitous indoor inferior home improvements.
