5. Take sample to QC lab for appearance, viscosity and pH test.
Note: The appearance of the batch will be clear once the hydration of the Hydroxyethyl Cellulose(338080) particles is complete. If after mixing for 35 minutes, the batch remains cloudy, additional mix time is required until batch appearance is clear.
Note: Under high alkaline conditions (pH>11) some oxidative degradation can occur to the Hydroxyethyl Cellulose (338080) lowering the batch viscosity.
6. Charge Bronopol (348039). Mix for 10 minutes.
Note: Under high alkaline conditions, Bronopol (348039) can decompose and generate formaldehyde
