Fastness of fluorescent whitened paper and board

Determination of the speed of transfer 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 bleeding of the OBAs.

The applied simulants are

  • Olive oil

  • 3% acetic acid

  • Alkaline salt solution (saliva simulant)

  • Distilled water

The test is relevant for optically brightened paper and paperboard but also for paper and board with recycled fibers, especially if they are intended for food contact.

When ordering this test, please indicate if the material is intended for short or long contact with food.
