Key points in the preparation of perfume

With regard to perfume products, the main ingredients are essence, alcohol and water. In addition, chelating agents, ultraviolet absorbers, pigments and other raw materials will be added. 

First of all, the addition of flavor, some people like strong smell, some people like light, there is no fixed model, according to the enterprise's cost budget, add 12%, 8%, or 20% can, there is no unified standard. 

The other is to add some deionized water. Usually around 10%, can be a little more, can also be a little less. The main purpose of adding deionized water is to reduce the very pungent taste of alcohol. In addition, it can reduce the cost, but can not add more, the essence and water are insoluble, adding more perfume is easy to turbidity. 

In addition, but to be on the safe side, the use of deionized water, but also the addition of metal ion chelating agent, metal ions wrapped, so that it does not participate in the reaction, reducing the probability of discoloration. 

Except for deionized water, of course. The pipeline should also be clean, because some manufacturers, his own pipes may have rust, there are dirty things in it, resulting in perfume discoloration. These are also some problems that need to be paid attention to. 

Some of the spices mentioned just now are relatively easy to oxidize, so BHT antioxidants will be added to the perfume. This is a very cost-effective antioxidant, and it is also widely used, which can delay the oxidation of this perfume as far as possible. In order to ensure that the whole perfume in the shelf life, there is no obvious change in physical properties. In addition, antioxidant needs to be tested, can be single, can be mixed, for different spices, to test different antioxidants, the use of an antioxidant is not realistic. 

Perfume bottles are usually transparent, and perfumes are placed in supermarkets, counters, or lights. So how to prevent the influence of light, at this time to add a ultraviolet absorber. Because some of the ultraviolet light is emitted from our lamps, this ultraviolet absorber absorbs it and provides some protection for perfume. 

Some perfumes may be primary or colorless. Some customers will color the perfume in order to please consumers. For example, the better red, yellow, green or blue and so on. Well, pigment is actually a very unstable substance, many of which change color easily under light. A more stable pigment in the molecular structure needs to be added and needs to be tested.Lagos fragrance oil 

The most important piece of perfume is the quality of alcohol. Choose that high-quality de-aldehydes, deodorized alcohol, because after alcohol fermentation, it will produce a lot of small molecules, such as methanol, acetaldehyde. These small molecular substances are particularly volatile and taste particularly prickly, making people very uncomfortable. In general, corn fermented alcohol should be better. 

After a perfume formula is finished, the product needs to do a stability test, that is, high temperature, low temperature, and then light to ensure that there is no visible change in physical properties throughout the test phase. It is necessary to observe its clarity, color, whether there is precipitation, fragrance changes and many other physical and chemical indicators. 

How does perfume keep its fragrance lasting? it needs to consider this problem from the point of view of spices, and it also tests the skills of flavoring, volatilizing fast raw materials, moderately volatile and slow volatile raw materials. So that the whole aroma is very sustained, lasting and coordinated. Do not let the perfume at first is this taste, after a while, into another flavor, such perfume will not be very successful. perfume wholesale China

There are some spices that are insoluble, or poor solubility, in this mixture of alcohol and water. You will find that perfume is a foggy state, not as clear as water, which is mainly caused by some natural ingredients. Because the components in many natural raw materials are very complex, why do they not dissolve? mainly, there are a lot of plant waxes, many of which are hydrocarbons containing more than 20 carbon atoms. Its solubility is very poor. Lagos fragrance oil

Well, one more point is about fragrance fixing agent. I define it as a relatively large molecular weight, a relatively high boiling point, at least 250 to 300 degrees, and the volatilization is very slow. From the point of view of physical indicators, the saturated vapor pressure is very low. It can form a strong intermolecular force with other spices, that is, van der Waals force. Fragrance fixing agent it can have fragrance or no fragrance. Fragrant, such as sandalwood, musk raw materials. Well, for those without fragrance, it is also possible to replace them with some odorless solvents that volatilize very slowly.
