Appendix A
(Normative)
Test Methods of the Acid Value
A.1 Principle
Titrate the free fatty acids in massage essential oil and massage oil by potassium
hydroxide standard solution.
A.2 Reagents and materials
Unless otherwise specified, the reagents are analytically pure; and the water is distilled
water or water of equivalent purity.
A.2.1 Ether-ethanol mixture: mix according to ether-ethanol (2+1, volume fraction).
Use the potassium hydroxide solution (3g/L) to neutralize until the phenolphthalein
indicator solution was neutral.
A.2.2 Potassium hydroxide standard titration solution [c(KOH) = 0.05 mol/L].
A.2.3 Phenolphthalein indicator solution: 10 g/L ethanol solution.
A.3 Instruments
A.3.1 Analytical balance: accuracy of 0.0001g.
A.3.2 Conical flask.
A.3.3 Burette.
A.4 Analysis procedures
Accurately take 3g~5g of sample (accurate to 0.0001g); place it in a conical flask; add
50mL of neutral ether-ethanol mixture (A.2.1); shake to dissolve the oil; and put it in
hot water, if necessary, to promote its dissolution. Cool to room temperature, add 2~3
drops of phenolphthalein indicator solution (A.2.3); titrate by 0.05 mol/L potassium
hydroxide standard titration solution (A.2.2), until it appears reddish; and the end point
is that the solution does not fade within 0.5min.
A.5 Calculation of results
The acid value is calculated according to Formula (A.1):
Appendix B
(Normative)
Test Methods of the Peroxide Value
B.1 Principle
During the oxidation of massage base oil and massage oil, peroxide is generated; and
it interacts with potassium iodide to generate free iodine. Titrate by sodium thiosulfate
solution; and calculate the content
B.2 Reagents and materials
Unless otherwise specified, the reagents are analytically pure; and the water is distilled
water or water of equivalent purity.
B.2.1 Saturated potassium iodide solution: take 14g of potassium iodide; add 10mL of
water to dissolve; dissolve with slight heat if necessary; cool and store in a brown bottle.
B.2.2 Chloroform-glacial acetic acid mixture: take 40mL of chloroform; add 60mL of
glacial acetic acid; and mix well.
B.2.3 Sodium thiosulfate standard titration solution [c(Na2S2O3) = 0.002 mol/L].
B.2.4 Starch indicator (10 g/L): take 0.5g of soluble starch; add a little water to make
a paste; pour into 50mL boiling water and mix well; boil. Prepare it just before use.
B.3 Instruments
B.3.1 Analytical balance: accuracy of 0.0001g.
B.3.2 Conical flask.
B.3.3 Burette.
B.4 Analysis procedures
Take 2.00g~3.00g of the mixed sample; place it in a 250mL iodine flask; and add 30mL
of chloroform-glacial acetic acid mixture (B.2.2) to completely dissolve the sample. Add
1.00 mL of saturated potassium iodide solution (B.2.1); tightly cap the bottle; and gently
shake for 0.5 min; then place in the dark for 3 min. Take it out and add 100mL of water;
shake well; and immediately titrate by 0.002 mol/L sodium thiosulfate standard titration
solution (B.2.3). When it is pale yellow, add 1mL of starch indicator (B.2.4); continue
to titrate till blue color disappears as the end point.
Appendix C
(Normative)
Test Methods of the Saponification Value
C.1 Principle
Under the reflux condition, boil the sample and the potassium hydroxide-ethanol
solution; and then titrate the excessive potassium hydroxide by a calibrated
hydrochloric acid solution.
C.2 Reagents and materials
Unless otherwise specified, the reagents are analytically pure; and the water is distilled
water or water of equivalent purity.
C.2.1 Potassium hydroxide-ethanol solution: dissolve about 0.5 mol/L potassium
hydroxide in 95% (volume fraction) ethanol. This solution shall be colorless or light
yellow. A stable colorless solution may be prepared by any of the following procedures:
a) Place 8g of potassium hydroxide and 5g of aluminum flakes in 1L of ethanol to
reflux for 1h; and immediately distill. Dissolve the required amount of potassium
hydroxide in the distillate and stand for several days; then pour out the clear
supernatant to remove the potassium carbonate precipitate;
b) Add 4g of aluminum tert-butoxide to 1L of ethanol; stand for a few days; pour out
the supernatant; dissolve the required amount of potassium hydroxide in it; stand
for a few days; then pour out clear supernatant from the potassium carbonate
precipitate.
Store this solution in a brown or yellow glass bottle equipped with a rubber stopper for
later use.
C.2.2 Hydrochloric acid standard titration solution: c(HCl) = 0.5 mol/L.
C.2.3 Phenolphthalein indicator: 10 g/L dissolved in 95% (volume fraction) ethanol.
C.2.4 Basic Blue (6B) Indicator: dissolve 20 g/L basic Blue (6B) in 95% (volume fraction)
ethanol.
C.2.5 Boiling aid: glass beads or porcelain particles.
C.3 Instruments
Commonly used instruments in the laboratory, especially the following instruments:
