Appendix A (Normative) Determination of dry sodium soap - Simplified method A.1 Principle Soap samples are acidified to generate fatty acids, which are insoluble in water. They are separated from other inorganic additives in soap. The weight and molecular weight of fatty acids can be measured, to calculate the dry soap content (content of sodium fatty acids). The results of this method include fat matter, average relative molecular mass, unsaponifiable matter, unsaponifiable oils and fats, and other organic matter insoluble in water in soap. A.2 Reagents A.2.1 95% ethanol: Neutralize with alkali until it is neutral to phenolphthalein indicator solution. A.2.2 Sulfuric acid: Aqueous solution with a volume fraction of 1:1. A.2.3 Sodium hydroxide: c(NaOH) = 0.5 mol/L standard titration solution, prepared according to the relevant provisions of QB/T 2739. A.2.4 Methyl orange indicator solution: 1 g/L. A.2.5 Phenolphthalein indicator solution: 10 g/L. A.2.6 Semi-refined paraffin: No.60. A.2.7 Wax block: Take water, semi-refined paraffin (A.2.6) and beeswax (GB/T 24314) in an aluminum pot in a weight ratio of about 10:4:1; place on an electric stove and heat until slightly boiling. Pour the wax block into a porcelain plate to make a cake; cool it; take out the wax block and dry it; cut it into pieces, so that each piece is about 7 g. A.3 Instruments A.3.1 Analytical balance: Resolution 0.0002 g. A.3.2 Beaker: 50 mL, 250 mL. A.3.3 Conical flask: 250 mL. A.3.4 Measuring cylinder: 10 mL. A.3.5 Burette without stopper (B grade): 25 mL. A.3.6 Watch glass: φ(85 ± 5) mm. A.3.7 Oven: Can be controlled at (103 ± 2) °C. A.3.8 Boiling water bath. A.4 Steps A.4.1 Determination of total fatty acids Weigh about 10 g of the test portion (6.2) (weighed to 0.001 g) and the homemade wax block (A.2.7) (weighed to 0.001 g), respectively. Place the test portion in a 250 mL beaker. Insert a glass rod. Add 200 mL of water at about 50 °C to the beaker; place it in a boiling water bath (A.3.8) and heat until the sample is dissolved. Measure 10 mL of sulfuric acid (A.2.2) (If necessary, add more sulfuric acid to fully acidify the sample). Slowly add it to the beaker while stirring. Start timing after stirring evenly; add a wax block (A.2.7) of known weight after the fatty acids are clarified. After 1 hour, take out the beaker and put it in a water tank to cool (if there are bubbles in the fatty acid, it must be heated and dissolved again until the bubbles are driven away). Take out the mixed wax block; absorb the water with filter paper; use a knife to scrape the mixed wax on the beaker wall and the glass rod; place it on the analytical balance to weigh (accurate to 0.001 g). The soap shall not be placed in a boiling water bath for too long for heating and decomposition; the test shall be completed within 2 hours. For some soaps with inorganic substances, about 2 g of sodium fluoride can be added during the test to ensure that the surface of the mixed wax cake is firm. The total fatty acid content W, expressed as mass fraction, is calculated according to formula (A.1): W - Total fatty acid content; m2 - Mass of mixed wax block, in grams (g); m1 - Mass of wax block, in grams (g); m0 - Mass of test portion, in grams (g); A - Correction value (generally not more than 0.5%). ......

A.4.3 Result and calculation The transparence T (%) of the transparent soap shall be calculated as per the Formula (A.1). Appendix B (Informative) Determination of Dry Sodium Soap – Simplified Method B.1 Scope This method is only applicable to soap-based soaps using fats and oils as raw materials. It is not applicable to compound soaps added other surfactants or functional additives. B.2 Principle The soap is acidified to produce fatty acids. The fatty acids are insoluble in water and separated from other inorganic additives in the soap. After measuring the mass of fatty acids and the relative molecular mass of fatty acids, calculate the dry soap content (content of fatty acid sodium). The determination results of this method include fats in the soap, average relative molecular mass, unsaponifiable matters, unsaponifiable fats, and other organics that are insoluble in water.

B.3.3 Methyl orange indicator solution, 1g/L. B.3.4 Phenolphthalein (GB/T 10729) indicator solution, 10g/L. B.3.5 Sodium hydroxide (GB/T 629), c(NaOH) = 0.5 mol/L standard titration solution; prepared according to 4.1 in QB/T 2739-2005. B.3.6 Beeswax (SB/T 10190). B.3.7 Semi-refined paraffin (GB/T 254), No.60. B.3.8 Wax block: Take distilled water, semi-refined paraffin wax (B.3.7), and beeswax (B.3.6) in an aluminum pot in accordance with a mass ratio of about 10: 4: 1; put them on an electric furnace to heat; slightly boil. After wax blocks are melted and mixed, pour them into a porcelain dish to make cakes; cool them; take out the wax blocks and dry them; divide the blocks to make each block about 7g in size. x – total fatty acid content, in %; m0 – mass of the test portion, in g; m1 – mass of the wax block, in g; m2 – mass of the mixed wax block, in g; A – corrected value (generally no greater than 0.5%). NOTE 1: The heating and decomposition time of soap when placing on the water bath should not be too long. The test shall be completed within 2h. NOTE 2: For some soaps added with inorganic substances, about 2g of sodium fluoride may be added during the test to ensure the strong surface of the mixed wax cake. NOTE 3: This method is not applicable to soaps containing less than 5% fatty acids. B.5.2 Determination of average relative molecular mass Take about 20g of the test portion (5.1) in a 250mL beaker; then add about 200mL of hot distilled water and dissolve it in a water bath (B.4.8). After dissolving, add excessive sulfuric acid (B.3.2) to acidify; indicate by methyl orange indicator solution (B.3.3); stir evenly; take off the beaker from the water bath after the fatty acid is clarified; cool off; after the fatty acid solidifies, discard the acidic aqueous solution under the fatty acid. Add hot distilled water to the beaker containing the fatty acid to dissolve and cool the fatty acid. After the fatty acid solidifies, discard the acidic aqueous solution under the fatty acid. Repeat the above operation until the aqueous solution under the fatty acid is neutral (yellow) against the methyl orange indicator solution. Pour the washed fatty acid into a 50mL small beaker containing a filter paper; then put it in (103±2) °C oven (B.4.7) to filter and dehydrate for about 30min; take it out and let it cool for a while; weight it before solidifying. Accurately take about 1g (accurate to 0.001g) of the prepared fatty acid in a 250mL Erlenmeyer flask; add 70mL of neutral ethanol (B.3.1); heat to dissolve; add 2 drops of phenolphthalein indicator solution (B.3.4); use sodium hydroxide standard titration solution (B.3.5) to titrate until the solution is light pink (without fading in 30s); then record the reading V. The average relative molecular mass of fatty acids (Y) is expressed in grams per mole (g/mol) and calculated according to Formula (B.2). ......
