Doctors at Children's University Hospital in Dublin, Ireland, noted that over a six-month period, they had treated six children with alkali eye injuries caused by liquid detergent tablets.

The children had squeezed the tablets, causing them to burst and spray detergent up into their eyes.

All the children were admitted to hospital where they were treated for two to five days.

Dangerous Chemical Ingredient

The damage to the children's eyes eventually healed, but the Irish experts say the injuries could have been more serious if the kids hadn't received prompt irrigation of the eyes after being splashed with the detergent.

"Alkali eye injuries are potentially the most severe form of chemical eye injury ... Although the detergent packaging displays a warning that the contents are irritant, and that the products should be kept out of reach of children, the real risk of injury posed may not be appreciated by consumers," the letter authors wrote.

"We propose that the warning label should be more obvious, and that the packaging should be modified to make it childproof," they added in a prepared statement.
