Question
I have revised my formula. Could you please review its compatibility and advise if a preservative is needed? If so, which preservative do you recommend and at what percentage? My current formula includes 79% Water.
Answer
Based on the staff's feedback, your revised formula is compatible.
The main adjustment recommended by the staff is to add a preservative. They specifically suggested Phenoxyethanol SA at 1%.
To include 1% Phenoxyethanol SA, you would need to reduce the Water percentage from 79% to 78% to ensure the total formula adds up to 100%.
The staff confirmed that the ingredients in your revised formula are compatible.
