  Is amodimethicone compatible with xanthan gum

  Posted by Abdullah on May 19, 2023 at 7:05 am

  I am making a silicone conditioner

  The formula is

  amodimethicone (and) trideceth-12 (and) cetrimonium chloride macroemulsion 5%

  EDTA 0.1%

  Preservatives

  Citric acid

  Thickener

  Water

  pH 4.5

  I used 0.8% and 1% HPMC as thickener but during stability test creaming happened at high temperature.

  I also have xanthan gum but as it is anionic, i wanted to know is amodimethicone or amodimethicone emulsion compatible with xanthan gum?

  I don’t think there should be any issue from amodimethicone itself, but from CTC. Now, if you want to prevent creaming without an emulsifier (CTC level might be too low to help you there) and only relying in your thickener, that would be quite challenging. If you don’t want to use a emulsifier, try at least some polymer with emulsifying properties (like hydroxypropyl starch phosphate). You might want to keep your HEC since the starch phosphate doesn’t give high viscosity. You could try using a silicone microemulsion instead.

    Thanks

    Will hydroxypropyl distarch phosphate work the same as hydroxypropyl starch phosphate?

  For the actual purpose, yes.

  @ketchito would adding a cold process emulsifier like polyglyceryl 4 laurate help the stability?

  Yes, it should.
