Question
What is the correct mixing order for a formulation containing powder ingredients, liquid ingredients, and Phenoxyethanol? What is the expected pH, and does it require adjustment?
Answer
Based on the conversation with the staff:
- Mixing Order: Your proposed mixing order is correct. You should dissolve the powder ingredients first, then add the liquid ingredients, and finally add the preservative (phenoxyethanol) at the end.
- pH: The formula will be slightly acidic and does not require pH adjustment.
