Transfer of optical brighteners from paper and board
Determination of the transfer speed of optical brightening agents (OBAs), also known as fluorescent whitening agents, from paper and board. The test is performed against UV light to provide a rating for the leaching of OBAs.
The applied simulants are:
Olive oil
3% acetic acid
Alkaline salt solution (saliva simulant)
Distilled water
Testing is recommended for optically brightened paper and board, but also for paper and board with recycled fibers, especially if they are intended for food contact.
When requesting an offer for this test, please indicate whether the material is intended for short or long-term contact with food.
