    Hello ,
     I am making a new mouthwash with a PH around 7 (or slightly lower) with Xlylotol , Vit C derivative (stable at that PH)   . Can I use euxyl 9010 as a preservative ?

    Some more info.
      I am using xylitol at 10% to reduce water activity and SAP at 3%. I dont have a chelator .

    What is the Aw of your product?

    Suggest you look at labels of competitive brands, esp. from major manufacturers.

    Sorry I have missed the reply.
      I have not checked the Aw but its rather low since in addition to the Xylotol I am also using about 5% of Propa 1.3
       I did look at competitors but no one is really making a PH8 rinse . (except one and he uses benzoic acid)
    So I guess my question is , does anyone know if Euxyl pe9010 can be used in oral care ?

    Think 9010 is prob not a good system in this app.    Think I’d check with FDa on this - it may require GRAS status.  
    The Aw is likely pretty high - bet >0.9.  A pH 8 rinse is not going to enjoy much protection from benzoic acid.
    Think about benzalkonium Cl.  It has its gaps so need good manufacturing hygiene.
