Product smell and viscosity changed 1 month later
This is my formula. I loved it for the first couple of weeks and now it has a “smell” not a bad smell just as noticeably different smell, almost like vitamin E to it and it’s “sticky”. It’s been in mostly 75 degree weather. Nothing extremely hot or cold. Any ideas why it would start changing after a month? I didn’t add a preservative because the pH is at a 3. I did a microbe test when I made it. It’s in a dropper bottle. I can retest it for microbial growth if you think that’s what happened.
