We're currently creating an open database of cosmetics and beauty/body products, just like we did for OpenFoodFacts, and I was wondering whether you knew of resources that might be helpful, and liberally licensed.
Status update: While keeping work on OpenBeautyFacts, we found:
- the UNII database of ingredients (Public Domain, produced by the US gov) that we got linked to Wikidata (yay).
- various glossaries and system with an unclear licence (Colour Index)
- various ressources by the European Union (COSING), some being usable (they're not as clear on licences as the US, but it's translations made for the EU, so open)
- Some similar projects but none with an open licence so far
We are now publishing our own data at https://world.openbeautyfacts.org/data
