After the well-known Sanitary
paper brands such as Qingfeng, Jierou and others were not in line with the natio
nal standard, the Beijing Co
nsumers Association (hereinafter referred to as “Jinghan Association”) o
nce again fired on daily necessities – two of Baoji’s two well-known brands, Shu Shubao and Duo Duo The move was accused of infiltration. Among them, blossoming is the worst performing product among all tested brands. As of press time, P&G still did not respond to the incident. The water absorption ratio, pH value, and microorganisms of all the samples were all qualified.

The problem of infiltration is not up to standard
According to data released by the Beijing Co
nsumers Association yesterday, it has tested a total of 38 brands in the market, and 10 of them have been tested to be inco
nsistent with natio
nal standards. According to the Beijing Co
nsumers Association, “the sanitary quality of Sanitary napkin
s is relatively good, but the problem of infiltration is not up to standard.” Among the brands that have been tested, P&G's Hushu and Duo are also listed.
The "Wu Shu Bao" that has been tested this problem is a cotton soft silk thin sanitary napkin (240mm) and a "flowering" cotton Shu ultra-thin sanitary napkin. The model is for multi-day/night use (280mm). According to the national standard "Sanitary napkins (including sanitary pads)" (GB/T8939-2008), the penetration of sanitary napkins should be "1.8g", but the measured values of the above two sanitary napkins are only 1.2g and 0.7g.
In addition to P&G's two products, there are four brands such as Ru Meng, Jing Chun, Desirable, and Ais Nie, which have been tested to have the same problem. According to the Beijing Consumers Association, the amount of infiltration is an indicator of the penetration rate of the test liquid to the surface of the sanitary napkin under specific laboratory conditions. The large amount of infiltration indicates that the sanitary napkin product penetrates quickly.
The new standard for sanitary napkins is lower than the old standard
It cannot be ignored that the sanitary napkin (including sanitary pads) (GB 8939-2008) cited in this test is a recommended national standard, that is, the enterprise can specify physical indicators higher or lower than the new standard. The reporter checked the information and saw that the standard is mainly the revision of "Sanitary napkins (including sanitary pads)" (GB 8939-1999), while the old ones are partially mandatory standards.
In the standard of infiltration, the new standard even greatly reduces the requirement of the infiltration index. The old standard stipulates that the penetration of sanitary napkins, first-class products, and qualified products shall not be less than 3.9g, 2.9g, and 1.9g, and the indicator is also defined as a mandatory standard. In the new standard, the products are not classified, and the penetration amount is not less than 1.8g.
In addition to the amount of infiltration, the new standard has different degrees of relaxation in terms of water absorption ratio and pH. Among them, the water absorption ratio decreased from 9 times or more to 7 times or more. Some experts pointed out that the improvement of this index is mainly provided by the polymer water-absorbent resin added in the sanitary napkin, and the reduction index can reduce the amount of the raw material added. In terms of pH, the standard was widened from 5.3-8.2 to 4-9. Among the various technical indicators, only the “deviation” requirement has been improved.
In the column of the drafting unit of the new standard, the reporter found that Guangzhou Procter & Gamble Co., Ltd. is impressively listed.
