Pros and Cons of Preserving Lotion with Benzyl Alcohol, Glyceryl Caprylate, Glyceryl Undecylenate?

What are the pros and cons of using KEM NAT or TRIstat ECO (INCI: Benzyl Alcohol, Glyceryl Caprylate, Glyceryl Undecylenate) as the preservation system for a leave-on O/W body lotion with a target pH of 5.5 and shelf life of 18 months? 

Also, are there any other preservatives that are particularly well suited to boost the anti-bacterial and/or anti-mold action of KEM NAT or TRIstat ECO (Brand names of Akema Fine Chemicals and TRI-K, respectively)? 

Any thoughts, comments and suggestions would be greatly appreciated.  Thanks.

     I tried it with good results no problems, just a bit expensive is all.
