Propyl paraben in lipbalm
Where can I find the most recent recommended/maximum concentrations by FDA/CIR/SCCS?
If I visit the websites, or google it, I get nothing but old documents.
Right now I want to put propyl paraben in my lipbalms, I’m thinking of 0.1%, but I’m not 100% sure. Same for allantoin. How much allantoin is allowed in a lip product?
Thanks in advance!
