  Cetosteryl alcohol co-emulsifier

  Posted by amitvedakar on August 13, 2018 at 8:41 am

  We currently use cetosteryl alcohol with cetomacrogol 1000 .

  This combination works fine for normal cream.

  What about  cetosteryl alcohol with sorbitan stearate combination.

  aproximate proportion?

  Any suggestions?

  Yes, if you want any advice you should list your whole formula or the ingredient list at the very least.

  My formula.

  Cetosteryl Alcohol  8%

  Cetomacrogol 1000 2%

  Preservatives

  Sod. Met. Paraben & sod. Prop. Paraben,

  EDTA.

  Propylen glycol—3%

  Petrolium Jelly-15%

  Liq. Parafin-3%.

  API-as label claim

  (Skin cream containing Active Pharma Ingredient)

  Well It’s cream base is fine for our pharma/some cosmetic products.

  Is good to  replace Cm1000 for Sorbitan Stearate?

  No, this probably won’t work.  Cetomacrogol 1000 (Ceteareth-20) has an HLB of 15.7.  Sorbitan Stearate has an HLB of 4.7

  If you are going to replace a high HLB material, you’ll need to use another high HLB material.
