Alcohol-Free Facial Disinfectant Spray
Question
I need a disinfectant spray formulation that is alcohol-free and can also be used on the face.
Which disinfectant ingredient should I use that is non-irritating and does not sting the eyes?
Also, what is the recommended usage percentage for this ingredient in the formula?
Answer
Alcohol-Free Disinfectant for Facial Spray
For an alcohol-free disinfectant spray that can be used on the face and is gentle, consider using Polyaminopropyl Biguanide (PHMG).
This ingredient is a synthetic polymer known for its effective antimicrobial properties against bacteria, fungi, and yeast. It is considered relatively mild compared to some other disinfectants, making it suitable for facial applications where irritation and eye stinging are concerns.
Recommended Usage Rate:
The typical usage rate for Polyaminopropyl Biguanide in cosmetic formulations is 0.1% to 1.0%.
- Note: Always perform challenge tests on your final formulation to ensure the preservative efficacy and safety before production and sale.*
