Mixing: put alcohol, essence and water into stainless steel or enamel, silver and tin lined containers in a certain proportion, stir and mix them for a period of time to allow impurities in essence to fully precipitate, so as to improve the clarity of the finished product and the anti turbidity in cold conditions. 3. Cooling: perfume will become translucent when it encounters a lower temperature. After that, if it is heated again, it will not be clear, and it will always be turbid. Therefore, perfume must be frozen before filtration. 4. After freezing, some insoluble substances precipitate out and are filtered to ensure their transparency and clarity.
