BHA Facial Foam Formulation
Question
Could you please provide a formulation for a facial foam containing BHA? I would like to know the necessary ingredients so I can purchase them correctly.
Answer
BHA Facial Foam Formulation
Here is some information on creating a facial foam formulation with BHA (Salicylic Acid).
Salicylic Acid is a beta hydroxy acid (BHA) known for its ability to exfoliate skin, unclog pores, and help with acne. For a wash-off product like facial foam, it's best to use a water-soluble form of Salicylic Acid for easier formulation.
Recommended BHA ingredients:
- Liquid Salicylic Acid (40% Active Salicylic, Cationic For Wash-Off): This liquid form is water-soluble and specifically designed for rinse-off products, making it very suitable for facial foams.
- ActiveRelease™ Salicylic Acid (Powder, Water-Soluble): This is a water-soluble powder form that releases Salicylic Acid gradually. It can be dissolved in the water phase of your formula.
- SalicSoft® (Betaine Salicylate): A gentler, water-soluble derivative of Salicylic Acid. Note that it requires pH adjustment to dissolve completely.
In addition to your chosen BHA ingredient, a facial foam formulation will typically require:
- Water
- Surfactants (foaming agents)
- Thickeners or stabilizers
- A preservative
You can select the specific surfactants and thickeners based on your desired foam texture and feel. Ensure the final pH of your formulation is appropriate for Salicylic Acid's effectiveness and skin compatibility.
