Aerosol dispenser assembly for
an air freshener product
U.S. Patent No. 10,427,862
S.C. Johnson & Son, Inc.
S.C. Johnson & Son, Inc., Racine,
WI, has patented an aerosol dispenser
assembly that includes a container
holding a liquid product and a
compressed gas propellant to propell
the liquid product from the container.
A design methodology for the actuator
body and swirl nozzle insert is disclosed
to maintain a small particle size or Sauter
Mean Diameter (D3, 2) of less than 48
.mu.m at a suitable spray rate (1.5–2 g/s),
while utilizing a compressed gas, volatile
organic compound (VOC)-free propellant
for an air freshener product. As
obtaining reduced particle size to compete
with liquefied petroleum gas (LPG)
propellants may result in a reduced spray
rate, it is anticipated that one or more
nozzles may be designed into the actuator
body to maintain a suitable spray rate.
Aerosol composition for hair care
