Isopentyldiol and Propanediol

Dear friends,

I like these two ingredients because of their moisturizing ability and reducing sticky of the formulation. But, I find that these have safety concern.
Anyone know about Isopentyldiol and Propanediol , Please share.

I appreciate and many thanks in advance.

    TO reduce "sticky", or tack, just use butylene glycol. Cheap, safe, more effective than those two diols you mentioned. Also, BG is no more or less moisturizing than the two you mentioned, meaning very little.
  • @chemicalmatt, thanks a lot. I will use butylene glycol
