Menthol bitter taste masking in mouthwash
Hi guys,
I’ve been having some trouble formulating a mouthwash that tastes good but is also super refreshing at the same time. I am using menthol and peppermint essential oil ( at around 2% together). What do you guys suggest I use to get rid of the bitterness of the menthol? I am using xylithol and salt as well in my formulation but it seems to do nothing against the bitterness.
I read in a patent that tocopherol helps in food, but not sure how that would work in mouthwash. -

maybe a small amount of acesulfame potassium ? Peppermint oil usually contains menthol (source is the same patent you’re reading) so are you sure 2% isn’t too much?

from experience, I’ve found sorbitol in substantial quantities (5% or more) gives a cooling sensation, and a sweetener can mask bitter tastesmenthol and peppermint oil are both very bitter by nature; the first thing I’d try would be reducing them -
I lowered it but the cooling effect is not the same at all. Xylithol supposedly has the highest cooling effect as compared to sorbitol. but its doing nothing in my formulation even at a bit higher than 5%… would spearmint work better or does it also have a a bitter taste?

You could add some cooling agent. We are using Menthyl Lactate or Menthyl Ethylamido Oxalate in our toothpastes.
