Question
I am using coffee grounds in a cosmetic formulation (specifically a gel). I have questions regarding its properties and safety:
- What is the particle size of the coffee grounds?
- Will the coffee grounds settle in a gel formulation?
- What is the risk of microbial contamination when using coffee grounds, and how can they be sterilized (e.g., by boiling)?
- Where do the coffee grounds originate?
Answer
Regarding the sterilization of coffee grounds for your shampoo formula, the suggestion to "boil with fire until boiling" means to boil the coffee grounds in water. This process uses heat to kill potential microorganisms present in the natural ingredient before adding it to your cosmetic formulation. This helps to ensure the stability and safety of your final product.
