The absorbent polymer beads are often marketed as colorful, slimy, sensory items for kids to play with. ... Parents should store water beads in a tightly sealed container that young children can ...
Water-absorbing polymers, which are classified as hydrogels when mixed, [3] absorb aqueous solutions through hydrogen bonding with water molecules. A SAP's ability to absorb water depends on the ionic concentration of the aqueous solution. In deionized and distilled water, a SAP may absorb 300 times its weight [4] (from 30 to 60 times its own ...
