How this service works
Fragrance reformulation checker — has this scent changed since its original release? IFRA-amendment-driven ingredient changes, community-documented vintage-vs-current differences, and how a batch-code-derived production year lines up against known reformulation events.
Output
Returns a reformulation assessment including whether the fragrance has changed since its original release, specific IFRA-amendment-driven ingredient changes, community-documented differences between vintage and current versions, the production year inferred from the batch code, and how that year maps to known reformulation events in the fragrance's history.
Example use cases
Authenticate vintage perfume collection
“I've got several older bottles from the 1990s and early 2000s that I inherited — can you tell me which ones have been reformulated since they were made, and whether the current versions are still considered good quality compared to what I have?”
Verify IFRA compliance reformulations
“I'm allergic to some ingredients and I noticed my regular fragrance used to have different components. Can you check what IFRA amendments might have changed the formula and whether the newer batches would be safer for my sensitivities?”
Find unchanged classic fragrances
“I want to buy a fragrance that hasn't changed much since its original release — can you look up a few classic scents and tell me which ones have stayed true to their original formula versus which ones have been significantly reformulated?”
Technical details
Endpoint
GEThttps://scentpulse.theaslangroupllc.com/api/scent/reformulation-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when a user wants to know if a specific fragrance has changed formulation over time, especially if they have a batch code to verify production year or want to understand IFRA-compliance-driven ingredient substitutions. Prefer over general fragrance info APIs when the core question is vintage-vs-current authenticity or formula integrity.
Side effects
- Unknown fragrance name or brand returns no match found
- Unrecognizable or malformed batch code cannot be decoded for production year
- Fragrance with no documented reformulation events returns clean/unchanged status
- Very obscure or niche fragrances may have limited community data and lower confidence
- Network or payment failure returns HTTP 402 or 5xx
