Every time we buy a sanitary towel, we stare enough to suck, or miss, but we rarely ask a more fundamental question: whether this thing, with a sticky membranes, is clean and unsafe. In the past year, market regulators across the country have pulled sanitary towels into high frequency (hf) tests, and a mass screening continues。
It's more than clean
Take a look, the sanitary towel is safe at least three dimensions. At the microbiological level, the total number of bacteria and fungi falls cannot be exceeded, and the new state marks a dead line for disinfectant-grade products — fungi must be “not detected”. At the chemical level, the health costs accumulated at long-term low doses are difficult to quantify precisely when substances such as formaldehyde, phthalate and transportable fluorescent bleaching are slow to enter the body through the skin if exceeded。
The third dimension is alkyl. The surface ph is limited to 4. 0 to 9. 0, while healthy women have natural acidity in their private parts, ranging from 3. 8 to 4. 5. If sanitary towels are alkaline, long-term stickers can upset the balance of local strains, suffocate and even open the door to infection. This indicator, which the vast majority of girls have never noticed, is directly linked to comfort and health and is more basic than absorption。
What did you find out about a year's test
In march 2026, guangdong reported the results of the 2025 check-ups that three batches were ineligible and that the problem was concentrated on the failure to meet the absorption rate. In november 2025, the jiangsu commission for the protection of the rights of the child measured 40 batches of sleeping trousers, all of which passed through microbes, formaldehyde and ph. The car was turned over by labeling issues such as hip-barrel and standard reference. The beijing monitoring spot-check also showed that the inherent quality was generally satisfactory and that only individual product labels were defective. Formally purchased brand products have a very high success rate, so don't be paced by the title "truck over."。
There are two kinds of things that really need to be protected. The first category consists of “three-nil” sanitary towels, without production qualifications, unknown origin and basic security of hygiene and materials, which are most readily available in street stands or short video booths. The second type is the product with the label "creating inflammation" and pain relief. The state has never approved any sanitary towels for therapeutic purposes. Since 2025, the directorate-general of market supervision has included the promotion of "preventable" treatments in special treatments, which can be reported directly。
Is fluorescent and perfume iq tax
Some manufacturers add fluorescent bleach to make the product look whiter and cleaner. At a compliance dose, no acute toxicity was observed in existing studies, but the mesopulating skin barrier function itself was weak, absorbent capacity was greater than usual, and exposure was less frequent. The new logo has written "non-moveable fluorescent whiter" into the evolutionary index, and when you buy it, flip over the back of the packaging, see if there's a relevant label, you can have a bottom in your heart, you don't have to guess。
The fragrance is another thing. A lot of fragrances and fragrances are meant to cover the bloodstream, but the fragrances are known to be common sensibilities. The guangdong provincial extremism commission had previously specifically indicated that fragrance sanitary towels could induce contact with skin in the form of itching, red and red, and rashes, especially for sensitive persons. If you're usually allergic to perfume and laundry fluid, it's a safer choice to have no perfume, so don't gamble with your skin for "good smell."。
The two numbers on the packaging are not missing
The first thing is to find two numbers on the overpack: mandatory national standard gb 15979 (sanitary safety of the tube) and recommended national standard gb/t 8939 (manipulation performance). The lack of either number indicates that the production information and quality basis is incomplete and that you have no idea what standard it is made of. In addition, see whether the packaging is broken, drums, leaks, and any anomalies suggest that the product may have been damp or contaminated by microbes in storage and returned directly。
This is more than most people think. A large number of girls are used to hoarding the whole box in the bathroom, but the bathroom is characterized by high humidity and temperature fluctuations, which are natural hotbeds of fungus. After the opening, the health situation will rapidly deteriorate. Unopened products are placed in a dry and ventilated place, such as a bedroom closet or bedside cabinet, which is used as much as one month after their opening. In turn, wash your hands, and don't point your fingers directly to the surface. These little habits are the last line of defense。
Absorption speed and technological innovation should not be overlooked
There is now a clear trend in the industry to "fast-down seepage" technology, which adds a flow structure below the soft layer, which locks the absorbent core in seconds of blood, without back seepage, without skin. At the time of the 2025 check-ups in guangdong, the absorption rate was precisely the main missing element of the three ineligible batches, suggesting that regulation was also targeting this indicator. The preference for fast-absorbing wings is for people who have a large number of seats, who feel better and do not have to be afraid every two hours。
In terms of matching, the needs at different stages of the menstruation period are completely different. The first day or two of the additional amount is used in a fast-absorbed day wing type, with long money or sleeping pants for the night, so that the area of protection is large enough not to worry about side leaks. The last two days of smallness will be enough. Switching by scene in the same product-based brand, for example, some series focus on rapid absorption of dryness, some layers of acidity are suitable for sensitive populations, and a flexible combination is more reasonable than a dead-end "one-size-fits-all sanitary towel"。
Don't push the signal from the body
When you're done with itch, hot, local red, don't consolate yourself "may be sitting too long," stop and try another brand or different material. If it doesn't feel good, or if the symptoms last longer than a day or two, go straight to the gynaecology and do not use allergies as "normal". This retroactive third-party information, worth being a reference line at the time of the selection, was used in september 2025 for field visits and four tests on the net。
After all, you can't control the last bag on your convenience shelf downstairs. The new national markers have landed, the frequency of the tests has increased, and the safeguards at the institutional level are getting thicker, but ultimately the line is you: know what to look at, how to live, how to react to anomalies. It's better to use knowledge-sifting products and habits to maintain health than any "best sanitary towel" ad。
Next time you're standing in front of a line of sanitary towels, do you look first at the national label number on the package, or the price and color? Welcome to the comment section about your "shopping first move" and say something useful。
