Amma,
My spray washed out. I am a product package reader, I learned the hard way, that I need to know what's in something and what hazards there might be. I think your manufacturer has to tell you if it has allergens, but I never count on it. I read, read, read, then spray outside. If it doesn't SAY it washes out........don't use it. Just my theory.
Hugs,
Sharon
