- a dispenser that holds a substance under pressure and that can release it as a fine spray (usually by means of a propellant gas)
- Usually, the product leaves the aerosol can at an angle of 90° relevant to the vertical axis of the can.
- Discharge an aerosol can to a 10-12 % nominal fill level (by mass) in bursts of 30 seconds maximum.
- Measure the discharge or flow rate of the aerosol product to be examined, so that the amount of test product dispensed can be more accurately gauged;
- Repeat steps (g) to (l) twice more (a total of 3) for the same can at the same distance between the gas burner and the aerosol actuator;
- Discharge an aerosol can to a 10-12 % nominal fill level (by mass) in bursts of 30 seconds maximum. Observe a 300 seconds minimum time period between bursts.
- Generates pressure in an aerosol pack, expelling contents when the valve is opened. Some liquefied propellants can act as solvents. REDUCING
- when full according to the complete procedure, with the gas burner in the range of 15-90 cm distance from the actuator of the aerosol can;
- Repeat steps (g) to (n) of the test procedure at a distance between 15 and 90 cm between the actuator of the aerosol can and the burner flame depending on the outcome of each test (see also 188.8.131.52.1.4 and 184.108.40.206.1.5);
- The chemical heats of combustion can be found in the literature, calculated or determined by tests (see ASTM D 240 as amended — Standard Test Methods for Heat of Combustion of Liquid Hydrocarbon Fuels by Bomb Calorimeter, EN/ISO 13943 as amended, 86.l to 86.3 — Fire safety — Vocabulary, and NFPA 30B as amended — Code for the Manufacture and Storage of Aerosol Products).
- Generates pressure in an aerosol pack, expelling contents when the valve is opened. Some liquefied propellants can act as solvents. REDUCING Changes the chemical nature of another substance by adding hydrogen or removing oxygen. REFATTING Replenishes the lipids of the hair or of the top layers of the skin. REFRESHING Imparts a pleasant freshness to the skin. SKIN CONDITIONING Maintains the skin in good condition. SKIN PROTECTING Helps to avoid harmful effects to the skin from external factors. SMOOTHING Seeks to achieve an even skin surface by decreasing roughness or irregularities. SOLVENT Dissolves other substances. SOOTHING Helps lightening discomfort of the skin or of the scalp. STABILISING Improves ingredients or formulation stability and shelf-life.
