Traditionally, aerosol hair spray products containing colorants (sometimes referred to simply as aerosol spray products) were introduced into the US market in the 1970s as sprayable cosmetic compositions for hair.
Sprayable cosmetic compositions for hair which are such aerosol color-containing hair sprays mainly consist of propellants, ethyl alcohol or isopropyl alcohol, color pigments and polyvinylpyrrolidone (PVP) monomers, and also their derivatives. It was an alcohol-based aerosol.

Moreover, the sprayable cosmetic compositions for these hairs generally have a high water solubility, and have a problem that they are easily scratched when touched.
However, to date, the state of the art of these products has hardly changed.

Mixing the propellant and liquid premix into the valve body 122 in this manner results in a physical agitation that reduces the average particle size of the aerosol and / or increases the evaporation rate of the solvent in the premix. . The resulting net result is a dry spray.

The inlet orifice 130 is typically an opening formed in the valve body 122 at a position where the dip tube enters the valve body 122.
The inlet orifice controls the amount of liquid premix to limit the amount of liquid phase that enters the valve body 122 may result in a faster expansion of the propellant within the valve body 122.
This results in a lower average particle size of the aerosol and / or a lower evaporation rate of the solvent in the faster premix, as well as a net result, again resulting in a dry spray.

Advantageously, an aerosol valve can be selected to select the spray pattern and spray rate of the product.
In combination with propellants (spray agents) and solvents, the spray pattern can be changed from narrow to wide, the spray rate can be adjusted, and application wetness or dryness can be increased or decreased.
As noted above, one method of adjusting spray dryness is by employing and adjusting the steam tap orifice 120, the valve body inlet orifice 130 and the propellant level.
In certain embodiments, when the propellant level is high relative to the liquid premix, the size of the vapor tap may have a lesser effect on the wettability or dryness of the aerosol application.

Thus, in one or more embodiments, the valve used in the valve system can include a seal ring on the stem seat. That is, a valve system that does not have a sealing ring on the stem seat may cause malfunction when an aerosol composition containing fine particles is used.
The types of malfunctions that can occur include slow shut-off, leaks during storage, and total blockage of the valve system.

That is, the valve system having the seal ring in the stem seat can largely avoid these malfunctions.
In one or more embodiments, the sealing ring is pushed into the gasket to wipe off particulate matter from the seal area during shut-off.
