I have never used flavoring from this company, but the concerns about lactic acid in the flavorings had me curious.
You may want to take a look at the following:
LACTIC ACID - in food
From this website comes the following information: "Lactic acid in food products usually serves as either as a pH regulator or as a preservative. It is also used as a flavoring agent."
Also of interest: Dulce de Leche flavoring at The Flavor Apprentice contains lactic acid. See here: Perfumers Apprentice - Dulce de Leche Flavor Since Linda at TFA is much more knowledgeable about vaping, maybe she would be a good one to ask.
