preserving oil solutions
Most massage oils can be a mixture of several oils and possible extracts (no water added).
Besides putting something in the formula for spread ability (isopropyl myristate) should I use a preservative as a precaution. Any recommendations?

Not necessary in general sense.

Lonza should has a few options for that or oil-soluble paraben?

If you want to be extra cautious, you could add Caprylyl Glycol and/or Glyceryl Caprylate (and) Glyceryl Undecylenate … both are oil soluble.
There is also an oil-soluble version of mixed Honeysuckle Extracts (in jojoba oil) … The Honeysuckle Extracts are essentially Parabens, but not labeled as such.

There is no microbial grow possible in anhydrous formulations, so why precaution?

@Tom
I was thinking how massage oil may be used in the intimate areas. From what I have been told oils should not be put in the intimate area because of yeast infections. I was thinking a preservative could provide some defense with extracts and other essential oils that could cause problems. -
Oh, never heard about that.. As MarkBroussard wrote, the longer glycols will be an option for you and you can try phenoxyethanol, too (or a combination)
