Shave Cream Stability


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?
