5.4 Packaging appearance
In accordance with QB/T 1685.
6 Test methods
6.1 Sensory indicators
6.1.1 Appearance, color
Take a sample and visually observe it at room temperature and under non-direct
sunlight.
6.1.2 Aroma
Take a sample and smell it to identify.
6.2 Physical-chemical indicators
6.2.1 Heat-resistance (hair shampoo)
6.2.1.1 Instruments
The instruments include:
a) Constant temperature incubator: temperature control accuracy is ±1°C;
b) Test tube: Φ20mm×120mm.
6.2.1.2 Operating procedures
Respectively pour the samples into 2 pieces of Φ20mm×120mm test tubes.
Make the liquid level about 80mm. Put a clean plug. Place a test tube to be
tested in a constant temperature incubator that has been pre-adjusted to 40°C.
Take it out after 24h. After it is recovered to room temperature, visually compare
it with the sample of another test tube.
6.2.2 Heat-resistance (cream shampoo)
6.2.2.1 Instruments
Constant temperature incubator: temperature control accuracy is ±1°C.
6.2.2.2 Operating procedures
d) Super thermostat: accuracy is ±1°C;
e) Measuring cylinder: 100mL;
f) Beaker: 1000mL.
6.2.6.2 Reagents
1500mg/kg hard-water: Weigh 3.7g of anhydrous magnesium sulfate (MgSO4)
and 5.0g of anhydrous calcium chloride (CaCl2). Completely dissolve them in
5000mL of distilled water.
6.2.6.3 Operating procedures
Pre-heat the super thermostat to (40±1)°C to maintain the Roche foam
instrument at a constant temperature of (40±1)°C. Weigh 2.5g of sample. Add
900mL of distilled water. Then add 100mL of 1500mg/kg hard-water. Heat to
(40±1)°C. Stir to make the sample evenly dissolved. Use the 200mL quantitative
funnel to pipette part of the test solution. Rinse along the tube wall of the foam
instrument. Then take the test solution into the bottom of the foam instrument
and align the standard scale to 50mL. Then use 200mL quantitative funnel to
pipette test solution. Fix the funnel center position. Drain the test solution.
Immediately record the foam height. Take the average value of the two errors
within the allowable range as the final result. The result is kept to an integer.
6.2.6.4 Precision
The absolute difference between two independent test results obtained under
repeatability conditions is not greater than 5mm.
6.2.7 Foam (cream shampoo)
Determine according to the determination for detergent foaming power (Ross-
Miles Method) in GB/T 13173. Read the starting foam height.
Mass concentration of test solution: 2%.
6.2.8 Effective matter content (hair shampoo)
6.2.8.1 Total solids
6.2.8.1.1 Instruments
The instruments include:
a) Analytical balance: accuracy is 0.0001g;
b) Constant temperature oven: accuracy is ±1°C;
6.2.8.2.2 Reagents
The reagents include:
a) 95% ethanol (chemically pure);
b) Phenolphthalein indicator (10g/L): Weigh 1.0g of phenolphthalein.
Dissolve in 95% ethanol. Use 95% ethanol to dilute to 100mL;
c) 0.1mol/L sodium hydroxide solution: Prepare according to QB/T 2470;
d) 95% neutral ethanol: Take an appropriate amount of 95% ethanol. Add
few drops of phenolphthalein indicator. Use 0.1mol/L sodium hydroxide
solution to titrate to reddish.
6.2.8.2.3 Operating procedures
Use the sample dried in 6.2.8.1.2. Add 100mL of 95% neutral ethanol. Heat in
the water bath till slightly boiling. Take it out. Slightly stir to make the sample
dissolved as possible. After standing for precipitation, pour the upper clear
solution into the Gourd crucible with a constant weight and a filter layer. Use a
suction filter to filter to the suction-filter bottle. Keep solid insoluble matter in the
beaker as much as possible. Use an appropriate amount of 95% neutral ethanol
to wash the beaker twice. Transfer the washing liquid and the sediment into the
Gourd crucible that has been constantly weighed to filter. Filtrate is in the same
suction-filter bottle. Put the Gourd crucible in the (105±1)°C constant
temperature drying oven for 3h. Take it out and put into the dryer to cool to room
temperature. Then weigh (to the nearest of 0.0001g).
6.2.8.2.4 Results expression
Calculate the inorganic salt content, X2, according to formula (2), in %:
where,
m1 - Mass of sediment in the Gourd crucible, in grams (g);
m0 - Mass of sample, in grams (g).
The result retains one decimal place.
6.2.8.3 Chloride
6.2.8.3.1 Instruments
where,
X1 - Content of total solids, %;
X2 - Inorganic salt content, %;
X3 - Chloride content (in sodium chloride), %.
The result retains one decimal place.
6.2.9 Active matter content (cream shampoo)
Determine according to the method specified in GB/T 5173.
6.3 Hygienic indicators
Inspect according to the method specified in the Cosmetic Hygienic
Specification.
6.4 Net weight
Determine according to the method specified in JJF 1070.
6.5 Packaging appearance
