    Look at the relative positions of the glycerine and propanediol. Then there’s the cinnamyl alcohol which I suspect is a preservative labelled a fragrance. Also, the benzyl salicylate, it’s used as a preservative in floral infusions.

    The preservative is:  Ethyl Lauroyl Arginate Hcl   Aminat G from Seppic.  There is also preservation boosting from the 1,3-propanediol and pentylene glycol … so there are actually 3 preservative ingredients in this formula.
