Clarification on BioSulphur EQ Ingredient Name and CAS Number for FDA Inquiry
Question
I need clarification regarding the ingredient name and CAS number for BioSulphur EQ. The CAS number listed on the supplier's MSDS is for Ichthammol. However, the FDA (อย.) informed me that the trade name is "albithol ammonium ichthosulfonate", which they stated does not match the MSDS information. Could you please clarify this discrepancy so I can respond to the FDA?
Answer
Clarification Regarding BioSulphur EQ CAS Number and Name
Thank you for reaching out regarding the discrepancy noted by the FDA concerning the name of BioSulphur EQ.
Our documentation, including the MSDS, correctly identifies the ingredient as Ichthammol. This is the official INCI (International Nomenclature of Cosmetic Ingredients) name for the substance.
Ichthammol is also known by other chemical names such as Ammonium Ichthosulfonate or Ammonium Bituminosulfonate. It is a complex mixture derived from the distillation of bituminous schists.
The term "albithol ammonium ichthosulfonate" used by the FDA appears to be an alternative name or a specific trade name referring to the same or a very closely related substance, which is Ichthammol.
You can inform the FDA that the product contains Ichthammol, which is the recognized INCI name and is chemically equivalent or analogous to the substance they are referring to as "albithol ammonium ichthosulfonate". The CAS number provided on the MSDS corresponds to Ichthammol.
We hope this clarification helps you in responding to the FDA.
