INCI Name Declaration for Sodium Polyacrylate (and) Polyisobutene in Thai FDA Registration

Based on the conversation provided, here's the explanation regarding the INCI name "Sodium Polyacrylate (and) Polyisobutene" and its declaration for FDA (อย.) registration in Thailand:

The INCI name "Sodium Polyacrylate (and) Polyisobutene" indicates a mixture of these two ingredients. While COSING might list the individual components, it may not always have entries for every specific mixture combination.

For FDA (อย.) registration in Thailand, according to the shared experience, you should declare the combined INCI name Sodium Polyacrylate (and) Polyisobutene and state the total percentage of this mixture used in your final product formulation. You do not need to split the percentage for each individual component (Sodium Polyacrylate and Polyisobutene) when listing the ingredients for the final product registration. The 50/50 ratio mentioned by the staff likely refers to the typical composition ratio within the "Sodium Polyacrylate (and) Polyisobutene" mixture itself as supplied, not how you declare it in your final product's ingredient list for registration.

Therefore, if you use 1% of the "Sodium Polyacrylate (and) Polyisobutene" mixture in your product, you would list it as:
Sodium Polyacrylate (and) Polyisobutene [concentration]% (where [concentration] is the total percentage of the mixture used, e.g., 1%).
