The packages introduced last year have the shape of a tetra and can be confused with drinks such as milk and juice, GP writes.
According to the Chemicals Inspectorate, they have received a picture of the detergent - when it is in a refrigerator.
In addition, it says on the packaging that the detergent is vegan, which may lead consumers to believe that it is safe to drink.
The company Orkla, which is behind the detergent, says it has sold millions of packages without receiving a single case where someone has confused it with a drink.
