4 Delivery systems for hair spray s 
Hair sprays are formulated as aerosols that are p ropelled  by pressurized gasses  (propellants)  or non -aerosols 
that are dispense d by manually depressing a pump . 
4.1 Aerosol hair spray s 
Aerosol hair  spray s are packaged i n container s under pressure and a release valve is used to emit the 
pressurized suspension into the air in a mist propelled  by propellant gases.  With an aerosol, you can usually 
get a continuous emission of the suspension as long as the gas or particles la st. (See figure 1 ) 
 
Figure  1 — Aerosol delivery system  
4.2 Non Aerosol hair  spray s 
Non-aerosol  hair spray s are packaged as  liquid s, usually in bottles  with an atomizer attachment such as a 
pump -sprayer . The pump sprayer uses springs, valves and tubes to m ix the liquid with small amount of air and DUS 1701: 2017

 ANNEX D  
(normative)  
 
Determination of the pr opellant composition  
D1 procedure  
D.2.1  The analysis of the pro pellant mixture in most aerosol is carried out conveniently by gas 
chromatography. For  Sampling, a hypodermic needle is fitted to the valve of the aerosol can and 
approximately 0.5  g of the pr opellant is injected into the heavy duty centrifuge tube closed with serum cap, 
containing about 8 ml of benzene. After mixing, 5 µl samples are taken out from this tube with a microlitre 
syringe and injected into the gas chromatograph.  
D.2.2  Two 4572 mm × 6.35 mm OD columns operated at 40 °C are recommended for the analysis 
containing 20 percent weight hexadecane and diethylhexyl sebacate respectively on silanized chromosorb 
W60/ S0 mesh.  
The first column should be used mainly for initial screening and the s econd column for the confirmation and 
determination of the identified propellants.  
Table D1 lists the relative retention data of the most widely used propellant together with some other fluorinate 
hydrocarbons and benzene used as the solvent IN the two col umns.

Testing of filled aerosol containers  
F.1 Procedure  
F.1.1  All filled aerosol  containers shall  be tested by immersion in a water bath set at 55  °C  
F.1.2  The conta iner shall be such that the pressure generated within the immersed container reaches not 
less than 90 percent of the pressure generated within the containers at equilibrium at 55  °C. 
F.2 Interpretation of results  
Any filled aerosol container that shall lea k, get distorted or burst as a result of this test shall be considered to 
have failed the test and shall be discarded.  DUS 1701 : 2017

Flame propagation  
G.1 principle  
The filled aerosol container is sprayed as a test flame under controlled conditions  and the length of the 
burning spray cone is measured.  
G.2 Apparatus   
G.1.1  In its simplest form, the apparatus consists of a base marked at 0.15 m intervals, an adjustable stand 
to carry the aerosol container which may be raised or lowered to accommodate differences in container 
height, a means of measuring the burning spray cone (usually a one metre fuel placed horizontally at the 
same level as the top third of the flame, the hottest part) a means of igniting the spray cone in the form of a 
test flame 0.0 5 m ± 0.005 m in height (usually a candle flame is used ).see figure G.1  
G.1.2  Water bath maintained at 20 °C .This equipment shall be used to bring the aerosol container and its 
contents to equilibrium at 20 °C (Heat the cans to 20 °C in the water bath)

 G.3 Procedure  
G.3.1  place the aerosol container on the stand. Depress the actuator and adjust the height of the stand so 
that the spray cone will pass through the upper third test flame (hottest pa rt). 
G.3.2  Bring the aerosol container and its content to the equilibrium temperature of 20 °C. Place the 
container on the stand so that the point where the spray emerges is 0.15 m from the test flame. Then light the 
test flame and depress the actuator for  15 seconds to 20 seconds. Record the total length of the burning spray 
cone and specify whether or not it burns back to the actuator . 
G.3.3  Extinguish the test flame and record whether the spray cone continues to burn while the actuator is 
depressed.  
G.3.4 Repeat each test twice and record the flame length as the average  of the three tests.  DUS 1701 : 2017

(normative)  
 
Net weight delivery  
Procedure  
H.1 For the determination of the net weight delivery , a random sample of at least three packages is 
selected. After  the removal of any dust cover or caps not required for dispensing the product, the gross weight 
of each packa ge is determined and after shaking for 15 seconds, the content of the lightest container is 
drained  by holding the valve wide open. Now the exhaus ted container is weighed . The result is called wet –
tare weight and is equal to the weight of the container plus any product remaining after draining.  
H.2 Consequently, the regeneration  allowance is determined and subtracted from the wet -tare weight to 
obtain the corrected wet -tare weight. The regeneration allowance is defined as the difference between the 
weight of the product which would be delivered through normal usage and the weight of the product delivered 
by the present accelerated procedure .It is c alculated by multiplying the label weight of the container by 0.02 g 
and rounding the result to the next lowest g ram. 
H.3 By subtracting the corrected tare weight from the gross weight, the adjusted net weight of the package is 
obtained. If this is greater  than 95 percent of the label weight the lot is assumed to be satisfactory. However, if 
it is less than 95 percent of the label weight, the lot is rejected.

Stability of smell  
I.1 Apparatus  
I.1.1 Porcelain cup  
I.1.2 Pincers  
I.1.3 Ten pieces of bleached gauze of dimension 5 cm x 10 cm  
I.1.4 Thermometer  
I.1.5 Hygrometer  
I.2 Procedure  
Put some pieces of bleached gauze which have been pre -washed in hot water without soap and dried into a 
porcelain cup. Spray continuously about 2 ml of the  sample into this cup. After the gauze  gets soaked, remove 
one piece using a pair of pincers. Without squeezing it, dry it in an environment with temperature of 27 °C ± 2 
°C and humidity of 65 ± 5 % for 12 hours.  
I.3 Results  
The product shall be taken to h ave passed the test if after 12 hours, the smell of the sample can clearly be 
picked up.  DUS 1701 : 2017
