I practiced a similar question, and I think benzyl alcohol is often used in compounding, so it might not be the right choice here.

I think I remember that lecithin is more of an emulsifier than a preservative, so maybe that's the answer?

I have a vague memory that benzalkonium chloride is also a preservative, but I could be mixing it up with something else.
