  Shave Cream Stability

  Posted by chemist1 on March 19, 2019 at 3:44 pm

  I am having issues with stability on a tubed shave cream that I have been working on recently.  At 45C, the viscosity increases dramatically,  At 25C, the viscosity drops by half.  Please see the attached formula.

  Water - QS

  Guar Hydroxypropyltrimonium chloride - 0.3%

  SCI - 27%

  Stearic Acid - 3%

  Glycol Distearate - 5%

  Cetearyl Alcohol - 2.25%

  Dimethicone - 0.25%

  NaOH (25%) - QS to pH 6.0 - 7.0

  Phenoxyethanol and Ethylhexylglycerin - 1%

  Any ideas on how to stabilize this type of formula?
