Aerosol Spray Development (from Lab to Shelf)
Aerosol Spray is a product which by application creates mostly the form of Aerosol (generally fine particles dispersed into the air ( i.e. Hairspray, Body Spray, Waterproof Spray); Foam (i.e. Shaving Foam, Hair Mousse, Foam Cleaners); Jet (i.e. Brake Cleaner); Gel (i.e. Shaving Gel, Shower Gel)

Today, the vast majority of Aerosol sprays are fi lled by so called “one-chamber” fi lling technology, where Concentrate (bulk) is mixed with the Filling Medium (propellant) – i.e. Hairsprays, Body Sprays, Waterproof Sprays, etc. Filling Medium in today’s Aerosol sprays are mostly mixtures of n-butane/i-butane/ propane or dimethylether, Carbon Dioxide, Nitrogen, Compressed Air. Less often used are HFC hydrocarbons and nitrous oxide.
The other, most commonly used Aerosol spray technology is so called “two-chamber” fi lling technology. This advanced technolo gy is based on separation of Concentrate and The Filling Medium. Such technology is often called BAG-ON-VALVE or BAG-IN-CAN, where the concentrate is fi lled in one step into the bag, attached either to the valve or to the can.The Filling Medium is fi lled out side the bag, into the aerosol can. During
the application by the end user, the com pressed Filling Medium is squeezing the bag inside the can. The advantage of this “two-chamber” fi lling technology is fi lling such concentrates which are less compatible with the fi lling medium or with the aerosol can itself.
Aerosol spray is composed with three ba sic parts: Primary Packaging (can, valve, actuator), Concentrate and Filling Me dium. During development of Aerosol spray, R&D must consider all three parts at once in order to achieve the desired product, application form and product characteristics. The valid legislation, customer’s marketing requirements (application type, claims) and available production technology must be considered as well.
Based on the knowledge of physi cal-chemical property of concentrate and together with customer’s requirements, the R&D technician searches and tests the most optimal valve, actuator and can configuration. Final application form and spray characteristics are also influenced with selected Filling Media and at last also
with the ratio between the Concentrate and the Filling Media.
Each newly developed Aerosol product has to run stability and compatibility tests, where selected formulation, aerosol can, valve and actuator are tested during se lected time. Very often, diff erent options of the above are tested, in diff erent tem peratures and in diff erent positions in or der to simulate the end consumer’s use of the product. Focus of these tests is on the reaction/compatibility of the Concentrate with the Filling Media and selected pack aging material. Also spray characteristics are very important to evaluate from the consumer’s point of view. Often formulation incompatibility, fra grance malodor, corrosion, valve plugging or product leaking is detected during these stability and compatibility tests. R&D then has to start all over again until satisfactory combination of formulation and primary packaging is found and the Aerosol prod uct's safety and functionality may be guar anteed during its shelf life.
