Facial Cleansing Gel Formulation for Combination Skin with Blackheads and Clogged Pores

Regarding your questions about the facial cleansing gel formulation and manufacturing steps:

1. Suitability of the formulation:
   The proposed formulation is generally suitable for combination skin with blackheads and clogged pores, primarily due to the inclusion of Salicylic Acid (BHA). However, based on the staff's advice:

   • If your skin is quite oily, you might consider increasing the amount of surfactant, such as increasing Sulfate Free Shampoo Base to 15% or adding other types of surfactants. You should test the current formula first to see if it provides sufficient cleansing without making your skin feel tight or dry.
   • For more severe clogged pores, you could consider increasing the concentration of Salicylic Acid.

2. Manufacturing steps:
   The proposed manufacturing steps are not necessary. The recommended method is much simpler:

   • Add all ingredients one by one into the water.
   • Mix gently until everything is combined. There is no specific order required for adding the ingredients.

Important Recommendations from Staff:

• Salicylic Acid: For easier use and to reduce the risk of precipitation, the staff strongly recommends replacing Salicylic Acid (BHA), Butylene Glycol, and Polysorbate 20 with Salicylic Acid EZ.
  • Using 5% Salicylic Acid EZ is equivalent to using 1% Salicylic Acid.
  • If you need a stronger effect for significant clogged pores, you can increase Salicylic Acid EZ to 10%.
• Preservative: Don't forget to include a preservative in your formula to prevent microbial growth.

This revised approach, particularly using Salicylic Acid EZ and the simplified mixing method, should make the formulation process easier and the final product more stable.
