This is a comment that was recently posted reposted up here so it could be read for all a very good question thank you Colin.
I don’t think CloSys II had the ingredient citric acid. The new CloSys has this ingredient and doesn’t seem to work as well. Do you have any thoughts on this?Thanks,CM
The ingredients in Closys and Closys II are exactly the same.
The product has a new name but absolutely nothing has changed with the ingredients. ( I just spoke to the company directly to make certain this is correct information).
For a little while the list of ingredients was inaccurate. They omitted to mention the citric acid component.
Citric acid is a stabilizer for Closys.
For completeness when they redesigned the packaging recently the company decided to add the citric acid onto the ingredient list.
Citric acid does not change the pH of the product and Closys remains neutral and pH balanced.
If you are concerned about Closys, my comment is to make sure you do NOT to add the favor vial included with each box.
Adding the flavor appears to inactive the product.
Also I recommend using Closys first BEFORE brushing teeth, and follow with Listerine and ACT used one after the other.
So, enjoy your Closys and be confident that it was only the packaging that changed!
