  • RSL test results stay valid for one year after the initial testing date or from the date which the formulation changed; whichever comes first.
  • No change to a formulation is allowed once a RSL ‘PASS’ has been received for a material, without a re-test. A change of formula is defined as where there is a change of a chemical ingredient or where there is a change of a proprietary ingredient, where the composition of that ingredient is not known. A change of supplier of a chemical ingredient is allowed as long as the new supply is chemically identical to the old.

Our voluntary chemical restrictions:

  • Polyvinyl Chloride(PVC)
    All GNA® approved inks are PVC-free.
  • Formaldehyde
    GNA® limits are much more stringent than legislated limits.
    GNA® requires all textile printing inks/ink components to be <5ppm.
    Formaldehyde (the detection limit) for babies, children and adults.
  • Alkylphenol Ethoxylates (APEOs).
  • Legislated limits are 1,000mg/kg for APs and APEOs in finished products. GNA® has a limit of 20mg/kg
  • Solvent based printing systems
    GNA® is limited to water-based formulations only.
