The quality of perfume can be identified from the following aspects:
Color: High-quality perfume is usually a clear, transparent liquid without any precipitation, and the color is natural and pure. At a temperature of 30 degrees Celsius, it will not change color after 24 hours. However, some perfumes containing concentrated jasmine essential oil are exceptions and may turn brown, because the color becomes more concentrated after the alcohol evaporates. Inferior perfumes are turbid, unnatural and impure.
Smell: Good perfumes have pure fragrance, with top notes, middle notes and base notes, and the fragrance lasts for a long time. Inferior perfumes smell impure. They seem to be fragrant at first, but they will feel greasy or even a little pungent after a long time, which can easily make people feel unpleasant.
Packaging: High-quality perfumes are exquisitely packaged, representing the quality and brand image of the product. The packaging is neat, the pattern is clear, and there is no gap between the bottle mouth and the bottle cap. The packaging of inferior perfume is simple, there may be a gap between the bottle mouth and the bottle cap, the packaging is not neat, the pattern is blurred, and the bottle may have cracks and other defects.
Fragrance retention time: High-quality perfumes have a long fragrance retention time. The fragrance of premium perfumes should be maintained for no less than 70 hours, and good perfumes should be maintained for at least 30 hours. Inferior perfumes generally have no fragrance after a few hours.
Diffusion: After high-quality perfumes are sprayed, a faint fragrance can be smelled in a large range, giving people a very comfortable feeling. Inferior perfumes may have good diffusion, but the smell is not good, or they need to be very close to smell.
Ingredients: High-quality perfumes usually use natural essences and specially treated alcohol, and the ingredients are safe and harmless. Inferior perfumes may contain ingredients such as fusel oil, petroleum-extracted pigments and harmful chemical preservatives.
