Do all perfumes contain alcohol? How long does the scent of perfume last?

Perfume generally does not cause allergies, but it is not ruled out. It is said that alcohol is added to perfumes. Does this mean that there is alcohol in all perfumes?

Not all perfumes contain alcohol, but most do. Only a few baby perfumes do not contain alcohol in order not to harm children's skin. However, alcohol-free perfumes are much less volatile than alcohol-containing perfumes, and the fragrance lasts for a shorter time, because the fragrance of perfumes can be emitted mainly due to the effect of alcohol. The reason why alcohol is added to perfumes is that the fragrance depends on alcohol to evaporate. The reason why perfumes have top notes, middle notes, and base notes is that the various concentrated spices evaporate at different times in alcohol, so that different smells can appear in different time periods. Perfumes without alcohol are relatively poor in this regard, with a short fragrance lasting time and a shorter shelf life.

The lasting time of perfume varies according to different skin types. Generally speaking, high-concentration perfume can last for 4 to 5 hours, while eau de toilette and cologne can last for 3 to 4 hours. If you spray it on clothes, it will last much longer, but the diffusion will be worse, which is not worth the loss. Therefore, if you want the perfume to work, you must spray it on the skin. Although some good perfumes can last for many days or even more than a week, the diffusion of the perfume is very low at that time, and it is only the residual aftertaste that can be smelled only when the nose is close to it, which is useless in normal social occasions.

1. Price: Although price does not reflect the quality of a perfume, if you know a brand name perfume and the price is very low, excluding the possibility of clearance sale, then it is very likely that the perfume is fake.

2. Packaging: Real perfumes are usually packaged in high-quality cardboard, and the packaging is exquisite, with complete information such as barcode, serial number, production batch, etc. Fake perfumes may be packaged roughly, often with extra glue and tape, and may have incomplete product information.

3. Foam: When buying perfume, we can identify the authenticity by shaking the perfume. Generally, real perfume will accumulate a lot of foam after shaking, and these foams will disappear completely in 20 seconds. If it is a fake perfume, either there will be no large amount of foam, or the foam will disappear instantly.

4. Smell: Real perfume usually has top notes, middle notes, and base notes. Not only is the fragrance long-lasting, but it can also change over time. Fake perfume has a single smell, which may even disappear in a short time. Those that can retain their smell for a long time are also likely to have the same smell.

5. Color: Real perfumes are usually clear, without sediment or unusual color changes. Fake perfumes may have sediment, especially after shaking.

6. Perfume bottle: The perfume bottle used for real perfume is also very particular. Not only is the design elegant and the material is very smooth, but it will also be equipped with a tight cap to ensure the quality of the perfume. Inferior perfume may be simply a glass bottle with a simple cap that does not have an anti-spill function.

1. Do not spray in places exposed to the sun: It is best not to spray perfume in places exposed to the sun, because perfume contains some spices extracted from natural plants. These volatile oils contain furanocoumarin ingredients. Long-term contact with ultraviolet rays will cause chemical reactions, causing dermatitis or dark spots on the face or body.

2. Do not spray directly on your face or on allergic skin: Because perfume contains a lot of alcohol, especially floral water, which has a particularly high alcohol content and is very irritating. Therefore, do not apply it to your face or on skin that is prone to allergies.

3. Don’t always spray perfume directly on the skin: Never spray perfume directly on the skin, because the skin will cause allergies due to long-term stimulation by alcohol. Therefore, you should change the method of use, and it is best to spray it on clothes.
