At what temperature will the mask go bad? Will it go bad at 40 degrees?

Many people know about facial masks, which need to be applied every day to keep the skin moisturized. So at what temperature will the mask deteriorate? Will the mask deteriorate at a high temperature of 40 degrees?

At what temperature will the mask deteriorate?

There will be no problem as long as cosmetics are stored in an environment where the minimum temperature is no lower than -10 degrees Celsius and the maximum temperature is no higher than 40 degrees Celsius. However, the most suitable storage temperature for cosmetics is between 5 degrees Celsius and 25 degrees Celsius.

Taking the cold resistance test as an example, the skin care products must be placed in an environment between minus 5 degrees Celsius and minus 10 degrees Celsius for 24 hours, and then placed at room temperature to test whether a series of indicators have changed. One of them is to see whether there is oil-water separation. If oil-water separation occurs, it is unqualified. The principle of heat resistance test is similar.

The national regulation is that the heat resistance test for lipstick is 45 degrees Celsius.

Will the mask deteriorate at 40 degrees?

The mask will not deteriorate at a high temperature of 40 degrees, and it is best not to exceed this temperature. If the temperature is too high, put it in the refrigerator.

The temperature of the refrigerator compartment is generally controlled at 2 degrees Celsius to 8 degrees Celsius (or 10 degrees Celsius). Therefore, qualified and non-deteriorated cosmetics will not separate from oil and water if placed in a refrigerator above 5 degrees Celsius.

This is the introduction to the suitable temperature for facial masks. As long as the temperature does not exceed 40 degrees, it will not deteriorate.
