Good evening,
I would like to ask if it is possible to substitute PEG-40 HCO with castor oil [INCI:Ricinus Communis (Castor) Seed Oil] in a simple lip butter formula, due to the lack of the first. 

Thank you!


  • No. They are not the same at all. One is an emulsifier, the other requires an emulsifier.

  • Are you sure it’s PEG-40 HCO in the lip butter? It’s has rather nasty taste. It could be hydrogenated castor oil which is actually a wax, not the PEG. What is your benchmark product?
  • Thank you very much for your time and your responces. :) At first, I had the misconception that the stability of the final product will be benefited by the use of an emulsifier. I am trying to formulate from the start a lip butter for personal use.

    PEG-40 HCO will give it very nice slip, but it has rather unpleasant taste. Since most of lipbalms don’t have water, you don’t really need an emulsifier. A lipbalm can be made of waxes (beeswax, candelila wax, carnauba wax) and oils. Melt 20% of beeswax with 80% of castor oil and you will get a very simple lipbalm. Butters tend to crystallize. You can mix oil and butter but don’t use more than 20% of butter (it’s not scientific it’s my experience with shea butter and cocoa butter). I saw a product with hydrogenated castor oil. It’s not the same as PEG-40 hydrogenated castor oil. The first one is a wax.
  • I will give it a try :) :)
