Formulating a BB Body Cream: Coverage and Texture Issues
Question
I want to formulate a BB cream for the body to provide skin coverage. What ingredients like Silica, Mica, and BB Micro Silk can be used for coverage? How can I incorporate these coverage powders into a cream base, and what steps can be taken to avoid texture issues such as a powdery feel or pilling?
Answer
Based on the discussion in this thread regarding creating a BB cream for the body, here is a summary of the concepts and an example formula provided:
A BB cream essentially combines a base cream (like a moisturizer or sunscreen) with ingredients that provide skin coverage.
Ingredients discussed for providing coverage include:
- Silica
- Mica (suggested for use at 5-10% of the total formula)
- BB Micro Silk
An example formula shared in the thread for incorporating BB Micro Silk into a cream base is:
- Emulsifier + Oil (e.g., fractionated coconut oil) - 13.0％
- Silicone (e.g., Cyclomethicone) - 12.0％
- Water + water-soluble ingredients - 65.0％
- BB Micro Silk - 10.0％
Please note that coverage powders like BB Micro Silk do not dissolve but absorb oil. If the final product feels powdery, increasing the oil phase in the formula can help.
The discussion also highlighted that combining coverage powders (especially those used in physical sunscreens like Zinc Oxide and Titanium Dioxide) with certain ingredients, such as polymers found in some emulsifiers (if used in excess), can sometimes lead to pilling (the product rolling off the skin like small particles or "ขี้ไคล"). Using silicones can assist in the better dispersion of powders, which may help mitigate this issue.
