Where is the Deep Clean lot mark?
Check the toothpaste tube seam and rear panel, then the carton bottom and flaps.
Check Deep Clean Cosmetic Batch Code
Deep Clean is Kao's Japanese oral-care range for gum care, including toothpaste and toothbrush products. Only consumable paste or gel carries a cosmetic-style production lot; a toothbrush model, dental advice, product volume and JAN barcode are catalogue information rather than manufacture dates.
Deep Clean FAQ
Is a toothbrush number a batch code?
No. Toothbrush model and accessory numbers are outside the consumable toothpaste lot.
Does the JAN show manufacture date?
No. It identifies the retail product and repeats across production runs.
Deep Clean codes on toothpaste and gum care
Before you rely on the decoded date
- Inspect the tube crimp and lower rear panel, then the carton bottom and side flaps for inked or embossed characters.
- Separate any Japanese expiry or use-by wording from the lot, and do not submit the toothbrush handle model or JAN as a production code.
Common lookup mistakes
- Keep the outer box until the code has been recorded because the tube and carton can print different supporting identifiers.
- Replace toothpaste after contamination, a damaged seal or an unusual smell or texture regardless of the estimated date.
