What is it?

Benzyl Alcohol is an aromatic alcohol used as a preservative, as the active ingredient in head lice treatment, and as a solvent.  It is most often created by combining benzyl chloride (a suspected carcinogen that has been used as a war gas) with sodium hydroxide (lye).  Sometimes it is created by reacting phenylmagnesium bromide (C6H5MgBr) with formaldehyde.

Benzyl alcohol also does naturally occur in green and other teas, and some essential oils including ylang ylang and jasmine. 

Is it a risk?

Steph's Opinion:

Should you avoid products containing ylang ylang or jasmine essential oils?  Benzyl alcohol is a component of these essential oils, but it is a minor constituent of these essential oils.  Toxic reactions and allergies to benzyl alcohol usually occur when the isolated chemical is used in a higher concentration as a preservative (1-5% of the formulation.) A product containing one of these essential oils may contain .5% of the essential oil, 1% of which may be benzyl alcohol, so the total concentration of benzyl alcohol would be .005%. If you were a person that has a history of being allergic to benzyl alcohol, then you may want to avoid these two essential oils just to be safe.  However, if not, this is not a large enough concentration to be concerned with for the general population. Jasmine and Ylang Ylang have a history of not causing sensitization, irritation, or toxicity when used properly.
