Can CCA be substituted as reference preservative?
2018 - IRG/WP 18-20641
…protective formulations remains probably the best method to find out the effective preservative concentration, the use of chrome-copper arsenate (CCA) as reference becomes debatable due to environmental and legislative reasons. This emerges from the European standardization bodies who have discussed reference…
