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: 2 Propylene 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
p>
(European Union 🇪🇺 region is labeled as slightly toxic to aquatic plants but does not affect normal use)
Its use time can reach 60 days or even longer in a 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.
The volatility is faster and better than DPM
Alcohol can be optionally added
p>
However, its flash point is low
In some international areas, it is labeled as a flammable and explosive item
Its use time can reach about 35 days at normal temperature.
Alcohol
Alcohol is generally used in human perfumes, aromatherapy sprays, etc.
If used in rattan aromatherapy
Not only will the volatilization speed be accelerated
The pungent smell of alcohol itself will also affect the effect of the fragrance
So currently, alcohol-based rattan aromatherapy is basically not produced internationally
Generally, alcohol solution-based rattan aromatherapy is used
The use time is at room temperature. It can be used for about 15-20 days
Overall, it is best to use DPM as a co-solvent
Although it is not as volatile as ISOPAR
But I personally think safety is more important than volatility
There are still relatively few domestic fireless aromatherapy products that use DPM as a co-solvent
KASIA It is one of the few brands that uses DPM as a co-solvent
Almost all of its fireless aromatherapy products have alcohol content
They all use DPM as a co-solvent
