Mouthwash

Posted by Cdsgames on April 20, 2022 at 8:11 am

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.
