Thanks.
I didn’t know phenoxyethanol is that good as anti bacterial preservative compared to DMDM hydantoin. -
@Abdullah - one of the problems with phenoxyethanol is the odor.

You can use combinations of others based on pH but would need testing

Yes but as these two are the least expensive, i have to stick with one or both of these two.
