  can too much PEG 40 Hydrogenated Castor Oil be dangerous?

  Posted by Anonymous on September 24, 2014 at 11:37 am

  Hello,
  Is it safe to use 30-40% of PEG-40 inside a product which interacts with the skin? (the rest are essential oils, water and SDA-40)
  Is there a limit to how much of the PEG-40 can be used?
  This amount is needed to make a clear substance from the oils and water.

  Thx.

  I cannot remember the particulars of the last CIR statement on PEG-40 HCO, but I do know it has been GRAS since the 1930’s, when it was invented. In fact, that compound was the very first nonionic surfactant ever introduced into commerce if I remember correctly. I’d be much more concerned with those essential oils promoting irritation.
