NEW YORK — A powdered alcohol intended to be mixed up into drinks has gained approval from a federal regulator.

The product, called Palcohol, had received the greenlight from the Alcohol and Tobacco Tax and Trade Bureau briefly last year before the bureau backtracked and said the label approvals had been given in error.

On Wednesday, bureau spokesman Tom Hogue told The Associated Press the issues were resolved and that four varieties of Palcohol were approved. But Hogue noted that states can also regulate alcohol sales in their borders.

The approval is a step forward for a small company whose product plans have already sparked controversy.

Several states have already moved to ban powdered alcohol, including lawmakers in Colorado who last month advanced legislation to temporarily halt its sale. That bill has since morphed to ensure the regulation of powdered alcohol as if it were liquid alcohol once it gets federal approval.
