Preservative with same INCI but different supplier.
Hi guys, I really want to know your opinion about picking a preservative for my bodywash, shampoo, and other rinse-off product.
Currently, I’m using kemidant L plus (DMDM hydantoin + iodopropynyl butyl carbamate). I’m thinking to try using MCI system, as it is cheaper in my region here. However, I’m confused as below:
1. The only available MCI system here is, Kathon LXE, and Kathon WT. Both inci is the same, while people mostly says that for cosmetic it should be using Kathon CG.
Do you think it’s fine to use Kathon LXE for my rinse-off product. In the brochures, mostly it’s written to be use for latex mixing, but again the INCI is the same, and the function is the same, which is to prevent bacteria and fungi.
2. I’m thinking of making my own preservative blend, because many small suppliers here only sell phenoxyethanol as single product. I believe this is only for bacteria, and needed to be mix with other fungi preservative.
Do you think making my own preservative blend is a good idea?
Do you have any recommendation of fungicidal preservative that works well with phenoxyethanol? (I’m thinking of potassium sorbate).
Thank you guys so much!
