The particulate matter you noticed is actually a polymer water-absorbent material. Currently, these polymer water-absorbent materials are commonly used in Bamboo baby diapers and are very safe. Since Newborn Baby Diapers adopts an ultra-thin and soft design, the proportion of water-absorbent particles is relatively high. Sometimes you can touch them. When they absorb water, they will turn into soft, small transparent beads. This does not affect your use, on the contrary, it is these water-absorbent beads that provide excellent water absorption and water-locking capabilities.
