Question
I am formulating a hair removal foam for use with a foam pump bottle. The formula has a high pH of 12-12.5.
- What foaming agent should I use?
- Is a preservative necessary for this type of formulation?
Answer
Regarding your questions about the foaming agent and preservative for your hair removal foam formulation:
- Foaming Agent: Based on the staff's recommendation, you can use Cond-Foam (Sodium Lauroyl Sarcosinate) at a concentration of 15-20% to create the foam texture suitable for a foam pump bottle.
- Preservative: Due to the high pH of your formulation (12-12.5), which is necessary for the hair removal agents to be effective, a preservative is not required. Microorganisms cannot grow in such a highly alkaline environment.
