What is the reason for shaking perfume foam?

After shaking the perfume, the amount of foam produced in the perfume may be affected by the following factors:

1. The formula and composition of perfume, in which the content and properties of surfactant may affect the formation of foam.

2. The way and intensity of shaking, too violent shaking may destroy the liquid structure in the perfume bottle, resulting in a decrease in foam.

3. The material of perfume bottle, some materials may foam more easily, and some materials may inhibit foaming.

4. Environmental factors such as temperature and humidity will also affect the formation of foam.

It should be noted that this does not mean that there is a problem with the quality of perfume or that it is a bad perfume. The quality of perfume mainly depends on its formula, composition, brand reputation and production technology, and the amount of foam produced is not the only criterion to judge the quality of perfume. If you are in doubt about a perfume, it is recommended to consult a professional perfume consultant or related institutions for more detailed information.
