Co-solvent for fireless aromatherapy

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
