Things You'll Need
Instructions
Don your lab gear before you start.
Add a small amount of the tetrahydrozoline to the surface of the watch glass with the spatula.
Add a small but equal amount of xylometazoline.
Mix the two compounds well with your spatula.
Transfer the mixture to the clear vial with your spatula. Cap it and label it. You now have a mixture that will exhibit a lower melting point than pure tetrahydrozoline.
