Since I have eczema I prefer to use products that only have ingredients that are derived from nature. But for the public, I reluctantly use a paraben-free preservative in my lotions to prevent the growth of harmful bacteria. I feel that it is the proper thing to do for the safety of my customers. Since I haven't found proven data on how effective natural preservatives are, I choose not to use them.
In my research, I have concluded that I only need to use them in products that contain water. So the only product that contains a preservative is my lotion. I make my lotion under sterile conditions and I also a paraben-free preservative to prevent harmful bacteria growth and to extend the shelf life. I only use the recommended amount (0.1-0.5% by weight) and I list all of the ingredients on the label.
I believe that honesty is the best policy when running a business and wanted to be transparent about this issue so that my consumers can make informed decision about my products. As I said early, lotions are the only product at this time that contains a preservative. So my soaps, butters, lipbalms, bath fizzies, etc. are free of preservatives!
Where do you stand on the issue of preservatives in cosmetics?
