What water beads are

Water beads are small beads of absorbent material that swell in water. CPSC says they can grow up to 100 times their size.

Why CPSC warns about them

CPSC warns about children swallowing water beads and putting them in their ears, and about acrylamide in water beads.

The toy standard

CPSC says a federal standard for water bead toys took effect for toys made after March 12, 2026, covering expansion size, acrylamide limits, and warning labels. CPSC says the rule is at 16 CFR 1250.4, and that some water bead products are not marketed as children's toys and fall outside it.

What CPSC advises

CPSC says not to allow children to play with water beads and to store them securely. CPSC says removing them from the home is the only way to remove the risk.

If a bead may have been swallowed

Call Poison Help at 1-800-222-1222. HRSA says "Poison Help is available 24/7 in over 100 languages." In an emergency, call 911.

FAQ

Does the standard cover beads already at home?

CPSC says the standard applies to water bead toys made after March 12, 2026. Its advice not to let children play with water beads is separate.

Are other expanding toys covered?

CPSC says ASTM F963 section 4.40 covers expanding materials in toys, "such as those that absorb water and get bigger."
