GB/T 13531.3-1995 《Generel methods on determination of cosmetrics--Determination of cloudiness》 Related products

This standard specifies the determination method of cosmetic turbidity, which is applicable to the turbidity inspection of cosmetics. During the inspection, the thermometer and the specified specification Glass testtube are used for operation. First, put ice cubes or ice water into the beaker to prepare the refrigerant. Pour the sample into the dried Glass testtube. The height of the sample is 1/3 of the length of the testtube. Seal the testtube with a stopper. Place the testtube in the refrigerant to chill down and observe whether the sample is still clear at the specified temperature. Judge whether the sample passes the inspection by comparing the clarity of the sample at the specified temperature. The sexual repeability is measured twice, and the results must be consistent. If the test results show that the specimen remains clear at the specified temperature, the specimen is considered to meet the turbidity standard.
