  What exactly is that supposed to be? Are the lacking % supposed to be preservatives and perfume?

  I can tell you what it’s not:

  A: o/w emulsion: no appropriate emulsifier

  B: w/o emulsion: no appropriate everything

  C: Stearate cream: no base, not enough stearate

  D : Cold cream: not enough wax

  Hello Pharma,  thank you. The lacking % is for  preservative and perfum.

  As said above…lacking a true emulsifer.

  What are you trying to make?

  Actually trying to make a simple cream base 50/50 oil and water.  Grams are = the % . I have the GMS glycerol monostearate in hand, can’t get the SE version here in my country.

  Sometimes it helps if you say your country.  Then others on the forum that live there can steer you to an emulsifier supplier.

  Well…if you have a 50% oil phases (if I understood correctly)…you will certainly need a real emulsifier, and way more of it.

  Is there anything a 50% oil phases product will do….that a 20% oil phase cream won’t do (and feel way better doing it)?

  As people already mentioned. Add an emulsifier and wind the sunflower back closer to 10 percent at least
