How is a beautiful car perfume made?

1. Pretreatment of car perfume solution: 

The raw materials for making perfume, such as plant essential oil and essence, must be pure and do not contain impurities, so they should be pretreated before use in order to ensure that the product has a clear appearance, mellow smell and round aroma. The average perfume on the market is made of alcohol, essence and water, which also requires the pretreatment of these three substances. 

1) the treatment of alcohol: including purification and aging. 

There are two commonly used methods for purification, namely, alkali reflux method in alcohol and potassium permanganate oxidation method. The aim is to remove impurities. After adding sodium hydroxide to alcohol, boiling and refluxing for several hours, and then fractionation one or more times, the purest part of the aroma was collected for the preparation of perfume. Or you can add potassium permanganate solution to alcohol, stir quickly and then rest, filter and precipitate, and then add activated carbon. After a few days, it is filtered by silica gel to further absorb impurities. In the purified alcohol, put a small amount of spices, sealed at 15 ℃ for a few months, that is, the aging process. 

2) Pretreatment of essence: a small amount of pretreated alcohol was added to the essence and used after aging for 1 month. 

3) Pretreatment of water: distillation or sterilization to deionize. Sodium citrate or EDTA is usually used to remove metal ions. 

2. Mixed car perfume: 

Put alcohol, essence and water in a certain proportion in a stainless steel or enamel or tin enamel container, stir and mix for a period of time, so that the impurities in the essence can be fully precipitated. In this way, the clarity of the finished product and the resistance to turbidity under cold conditions are improved. 

3. Perfume aging: 

The mixed perfume is aged in an airtight container equipped with a safety valve. There are two kinds of aging methods of perfume: physical method and chemical method. Physical methods include mechanical stirring, air bubbling, infrared, ultraviolet light irradiation, ultrasonic treatment, mechanical vibration. Car perfume essential supplier.

Chemical methods include air, oxygen or ozone bubble oxidation, silver or silver chloride catalysis, tin or hydrogen reduction. During the aging period, the smell of perfume gradually changed from rough to mellow. However, if the blending of flavors is not appropriate, it will also produce an unsatisfactory smell. As to the length of time required for ageing, some people think that it will take three months, while others think that it should be longer or shorter. It can be adjusted according to production conditions and other factors. 

4. Liquid cooling: 

Perfume meets a lower temperature, it will become translucent or foggy, and after that, if it is heated again, it will no longer be clarified, and it will always be cloudy. Therefore, car perfumes must be frozen before filtering. 

5. Machine filtering: 

Some insoluble substances precipitate after aging and freezing, and the purpose of filtration is to ensure its transparency and clarity. Filter press is used for filtration, and filter aids such as diatomite are added to adsorb precipitated particles, otherwise the sediment blocks the pore of the filter cloth. After adding filter aid, cool the perfume to about 0 ℃ and maintain this temperature during filtration. The temperature of the filter press can be cooled by repeated cycles of cooled perfume. When the sediment produced by aging and cooling is removed, it can be restored to room temperature and then filtered through a fine porous cloth, which can ensure that the product remains clear and transparent during storage and use. 

6. Perfume bottling packaging: 

Those sitting at the bottom of perfume containers should be cleaned with distilled water. And it will leave some space at the neck of the bottle to prevent the car perfume from exploding in hot weather during storage. Car perfume essential wholesale

7. Finished product inspection: 

First of all, the base or container of the car perfume is visually checked for defects, and then the instrument is used to compare the color, specific gravity, diopter and alcohol content, and the unqualified products are extracted and re-produced. Car perfume flavour

After reading the production process of these car perfumes, I believe everyone must have a new understanding of it, and will be more comfortable in choosing and using car perfumes in the future.
