Mayonnaise does not really freeze solid until around -50 F degrees.
However mayonnaise can begin to freeze and separate around 32 F.
It has been found that a temperature of below approximately -50°F. completely destroys the delicate emulsion of mayonnaise.
The upper limit of operability for such inert liquid bath has been found to be approximately 0°F.
The mayonnaise-containing product to be frozen is maintained in the bath until completely frozen.
If you freeze mayonnaise, it will look normal while still in frozen form.
Mayonnaise is an emulsion typically made of oil, egg yolks, vinegar or lemon, and seasonings.
As mayonnaise thaws, that emulsion will break, leaving you with the liquid, acidic ingredients and oil floating on top of the yolk base.

Mayo does not need to be refrigerated.
If the mayo is commercially made it requires no refrigeration and can be safely left at room temperature.
Although it's recommended to put opened jars of mayo in the fridge but it's not really required.
Commercially produced mayonnaise, as opposed to the homemade version, does not need to be refrigerated, according to the report.
Food scientists find it's because mayo undergoes strict testing and "its acidic nature slows the growth of the bacteria associated with food-borne illnesses,'' according to NPD Group.
