Adding Ethoxydiglycol to Water Phase in Formulation

Question

Based on the previous discussion and staff advice, I understand that Ethoxydiglycol (4%) should be added to the water phase of my formulation. My original water phase includes:

DI water (9)
Creatine (3)
EDTA (5)
Phenoxyethanol (6)

Could you confirm that Ethoxydiglycol should be added to this specific mixture (step 2 in my original process) before combining it with the oil phase? I also want to ensure this is correct considering the other recommendations: increasing Lipid Soft (4) to approximately 10%, mixing Kojic Acid (1) into the oil phase (Lipid Soft), and adding the oil phase after the main mixture has cooled below 40°C.

Regarding adding Ethoxydiglycol (4%), based on the staff's advice, it should be added to the water phase.

In your original steps, the water phase consists of:

DI water (9)
Creatine (3)
EDTA (5)
Phenoxyethanol (6)

So, you should add Ethoxydiglycol to this mixture (step 2 in your original process) before combining it with the oil phase.

Remember the staff's other recommendations:

Increase Lipid Soft (4) to around 10%.
Mix Kojic Acid (1) into the oil phase (Lipid Soft).
Add the oil phase (containing Lipid Soft and Kojic Acid) in the final step, after the main mixture has cooled below 40°C.
