Q8/T24B6—2000
This standard is a revision of the original standard GB8112-1987 "Laundry Soap" (this standard was published by the State Bureau of Light Industry [1999] No. 112 and converted to standard No. QB37561999, the content is before), and the main revisions are as follows. The "simplified method" is added as the factory inspection method for the dry soap content test. The solution preparation method for the "foaming power" indicator is changed to: prepare 1% soap solution directly according to the net content marked on the package.
Quantitative packaging requirements are tightened.
-Packaging inspection is more stringent and operability is enhanced. 1. Cancel the shelf life of laundry soap.
This standard is proposed by the Industry Management Department of the State Bureau of Light Industry. This standard is under the jurisdiction of the National Surfactant Detergent Standardization Center. The responsible drafting unit of this standard: Shanghai Soap Co., Ltd. The main drafters of this standard: Fei Chaohua, Xiang Honglan, Hu Minjun, Xu Peiqi. From the date of implementation of this standard, the industry standard QB3756-1999 "Laundry Soap" issued by the former State Bureau of Light Industry will be abolished.

Dry soap content, %
Chloride content (as NaCl)
Free caustic soda content (as NaOH)
Ethanol insoluble matter, %
Foaming power (5min)

The net content of small packages of laundry soap must comply with the provisions of the State Technical Supervision Bureau Order [19951 No. 43. 5 Test method
Analytical reagents and distilled or deionized water should be used in the analysis. Product preparation: First weigh each piece with a scale with a graduation value of not less than 0.1g. Then cut three times vertically through the middle of each piece to divide it into eight parts, take the two diagonal parts and cut them into thin slices or pieces, mix them thoroughly, and put them into a clean, dry, sealed container for later use.

Randomly select the same number of samples from each box sample, so that the total number of sample blocks is not less than 30. Divide the block samples into three parts, store them in clean plastic bags and seal them. Indicate the product name, batch number (or production date), sampling date and sampler on the label. The delivery party shall each hold one copy for testing, and the other copy shall be kept by the delivery party for inspection. The storage period is one month.
6.5 Judgment rules
If the inspection of the customer's indicators fails, re-sampling can be carried out. If the re-inspection result is still unqualified, the batch of products shall be judged as unqualified. The results of the physical and chemical index inspection shall be judged as qualified or not by the rounded value comparison method. If one indicator fails, double sampling can be carried out to re-inspect the unqualified item. If the re-inspection result is still unqualified, the batch of products shall be judged as unqualified. , then the batch of products is judged to be unqualified. 6.6 If the inspection results of the letters of delivery between the two parties are different and they cannot reach an agreement, they may request arbitration inspection and implement sampling according to the 6th inspection rules. The arbitration inspection results shall be the final basis. 7 Marking, packaging, transportation, storage
