Answer

Subject: Adjusting pH of Natural-C Glycol™ with TEA

Regarding your question about adjusting the pH of Natural-C Glycol™ from 2.5 to 3.5 using TEA, it is not possible to provide an exact percentage of TEA needed.

This is because:

  • The pH of chemical ingredients, including Natural-C Glycol™ and TEA, can vary between different production lots.
  • Even within the specified pH range for Natural-C Glycol™ (e.g., 2.0-3.0), the exact pH of a specific lot will differ.
  • Similarly, the strength of the base (TEA) can also vary slightly between lots.

Therefore, the amount of TEA required to reach a target pH of 3.5 will depend on the specific lots of Natural-C Glycol™ and TEA you are using.

pH adjustment is a process that requires measurement. To accurately adjust the pH to 3.5, you would need to add TEA gradually while measuring the pH until the desired value is reached.
