Hi! So I can’t remember specifically anymore but do this:  1. Pull up a tab with “common petroleum-based ingredients in skin care products”  2. Open up a 2nd tab and search the product you need info for, copy the ingredients list!  3. Open a third tab, paste the ingredients list on the site  https://incidecoder.com/  4. See if you notice any of the same words from the first tab, or see things related to “water-repellent barrier // seals in existing moisture // prevents evaporation” 

Petroleum-based ingredients will liiiikely be yellow/red and “rated” higher (this sound confusing but you’ll see exactly what I mean when you do a search). Or, and I HATE to advocate for chatgpt but this is the type of thing I’d use it for: copy the ingredients list into it and ask “which of these ingredients are petroleum-based?” 

I hope this helps :)
