SB is sodium benzoate?. It works at low pH, so it won’t work.
We can’t guess what will suit you since we don’t know what’s on each product. Preservation systems are made accordingly.

Also, preservation also depends on your manufacturing conditions. Without stability testing you can’t say something is going to have a 2 year shelf life.

BHT is not a preservative.

0.5% BHT, isn’t that way too much?
In a document from a supplier I have here they recommend 50-100 ppm (0.005 - 0.01%)
