While I was online shopping, I stumbled upon an organic linen spray product claiming that it only contains three (3) ingredients:
1. distilled water
2. essential oil
3. lactic acid
I believe that the lactic acid serves as the preservative for the formulation. I know lactic acid is used as preservative for food but for cosmetics formulation, I'm not so sure. What are your thoughts? What do you think is the percentage of lactic acid in the formulation?
