Get rid of Vit E. That is absolutely unnecessary as part of a sanitizer. It’s added in tiny amounts in commercial products for marketing purposes, but it really has no effect in a sanitizer.
If you really want to keep it:
Phase A
Water, Glycerine, Isopropyl Alcohol
Phase B
Decyl Glucoside, Tocopherols (mix very very well)
Phase C
Preservatives and Fragrance
NOTE: For alcohol to be effective you need to use over 60% by volume in your formulation. At this level you don’t need other preservatives.
Procedure: mix phase B into phase A until combined and homogenous. Then add preservatives and fragrance one by one and stir until combined before adding the next.
