face wash crystallization(Freezed).

I M MAKING A TRANSPARENT SOAP BASE FACE WASH WHICH HAS PH 9-10 
ITS BECOME TRANSPARENT WHEN I ADD POTASSIUM HYDROXIDE AT 70- CELCIUS IN IT BUT  AFTER SOME DAYS AT ROOM TEMPERATURE ITS BECOME CLOUDY OR CREAMY WHEN I PUT IT IN LOW TEMPERATURE AT 10 DEGREE  CELCIUS .
AND HOW CAN I MAKE IT MORE THICK.
INGRDIENTS
PALMITIC ACID        0.5%
LAURIC ACID            12.5%
MYRISTIC ACID            2.5%
POTASSIUM HYDROXIDE          4.5.%
COCOBETAIN                   8%
GLYCERINE                          5%
CDEA            3%

WATER TO MAKE 100 %
PLEASE HELP ME TO SOLVE THIS PROBLEM

    @UsmanAli First DEL the glycerin, as it is denying you any viscosity that might be obtained with builders. To keep clarity, you need a stronger hydrotrope than coco-betaine, I'll suggest disodium cocoamphodipropionate 40% (Colonial, Solvay, others) which works very well at pH 9 - 10. As for builders, that is more difficult, though your alkanolamide (CDEA) should do some good here once the glycerin is gone. DO NOT waste time with salt.  You can thicken with an acrylate copolymer or a cellulosic gum, methylcellulose being most electrolyte tolerant.
