All fireless aromatherapy requires co-solvent
Co-solvent is the insoluble drug and the third substance added
To form a soluble intermolecular complex in the solvent , associates or double salts, etc.
To increase the solubility of the drug in the solvent
There are generally the following three types of co-solvents
Explain them respectively
p>
DPM: dipropylene glycol methyl ether
The most commonly used perfume co-solvent in the world
It has the characteristics of high stability, non-toxic and harmless, easy to volatilize, and no mixed odor
(European Union 🇪🇺 region is marked as slightly toxic to aquatic plants but does not affect normal use)
The service life can be up to 60 days or even longer in normal temperature environment
ISOPAR ：Synthetic isoparaffin oil
ISOPAR is divided into many types
The models commonly used as perfume co-solvents generally include H, I, etc.
Its volatility is faster and better than DPM
And alcohol can be optionally added
But its flash point is lower
In some areas internationally, It is marked as a flammable and explosive item
Its use time can be up to about 35 days in a normal temperature environment
Alcohol
Alcohol is generally used in human perfumes, aromatherapy sprays, etc.
If used in rattan aromatherapy
it will not only speed up Evaporation speed
The pungent smell of alcohol itself will also affect the effect of the fragrance
So currently, alcohol-based rattan fragrances are basically not produced internationally
Usually use rattan aromatherapy based on alcohol solution
It can be used for about 15-20 days in a normal temperature environment
In summary, it is best to use DPM as a co-solvent
Although the volatility is not as good as ISOPAR
But I personally think that safety is more important than volatility
There are still relatively few fireless aromatherapy products in China that use DPM as a co-solvent
KASIA is one of the few brands that uses DPM as a co-solvent
Almost all of his brands All fireless aromatherapy products have alcohol content
All use DPM as a co-solvent
