Opened Shelf Life
Q. How long are RICCA products good after they are opened?
A. RICCA CHEMICAL COMPANY cannot assign an expiration date to any of our products once they have been opened, because we do not have any control over the environment where they are used and stored. If the product is stored at the indicated temperature, kept tightly capped when not in use, and if care is taken to avoid contamination, most products should be suitable for use through the expiration date listed on the bottle.
