Disposable hygiene product testing

1、 Core testing indicators and standard system

1. Microbial safety: invisible deadly risks

• National standard requirements（GB 15979）：

• Total bacterial colony count ≤ 200 CFU/g

• Pathogenic bacteria (such as Pseudomonas aeruginosa) should not be detected

• Enterprise blind spots：

• Neglecting the monitoring of sedimentation bacteria in the production environment (filling workshop needs to be ≤ 200 CFU/m ³)

• Failure to regularly check the sealing of packaging (secondary pollution caused by damage)

2. Chemical safety: prevention and control of hidden toxicity at the source

3. Physical performance: User experience and functional guarantee

• absorption performanceSanitary napkins have an absorption capacity of ≥ 7.5g (GB/T 8939)

• ImpermeabilityMedical protective pads must pass the ISO 22609 blood penetration test

• tear resistanceBaby diaper core layer breaking strength ≥ 40N

2、 Analysis of Common Quality Accident Cases in Enterprises

Case 1: An incident of excessive preservatives in a certain maternal and child brand wet wipes

• problemMethyl isothiazolinone (MIT) in wet wipes exceeds the standard by 3 times

• consequenceOver a thousand complaints of skin allergies from consumers have been received, and products have been taken down from the internet, resulting in direct losses of over 8 million yuan

• rootFailure to conduct anti-corrosion performance challenge test according to EU ISO 11930 standard

Case 2: Raw material adulteration in ODM factory leads to leakage of sanitary napkins

• problemWater absorbent resin (SAP) mixed with cheap starch

• consequenceAbsorption decreased by 40%, cooperative brands terminated orders and claimed compensation

• lessonLack of raw material entry FTIR spectroscopic analysis (able to identify material molecular structure)

3、 Full process quality control solution

1. Raw material entry inspection

• Key objects: Non woven fabric, fluff pulp, polymer absorbent material

• Required inspection items：

• Total bacterial count of raw materials (ATP bioluminescence rapid screening)

• Heavy metal migration capacity (lead ≤ 10mg/kg, cadmium ≤ 1mg/kg)

2. Production process monitoring

• environmental control：

• Cleanliness of production workshop (planktonic bacteria ≤ 500 CFU/m ³)

• Real time monitoring of temperature and humidity (temperature 18-25 ℃, humidity ≤ 65%)

• Process compliance：

• Uniformity of hot melt adhesive coating (detected by infrared thermography)

• Ultrasonic welding strength (≥ 15N/15mm)

3. Finished product compliance verification

• Toxicological testing：

• Multiple skin irritation tests (30 human samples)

• Vaginal mucosal irritation test (mandatory for medical device products)

• Market Access Certification：

• China: Registration of Consumer Goods/Makeup Brands

• EU: ISO 10993 biocompatibility testing

• United States: FDA 21 CFR 801.430 (Medical Products)

4、 Policy Trends and Response Suggestions for 2024

1. China's regulatory upgrade：

• Disinfection grade products need to apply for a "disinfection number" (approval period extended to 90 days)

• Compulsory labeling of the full composition table of the package (including chemical name of preservative/essence)

2. International regulatory updates：

• EU REACH regulation adds 8 restricted substances (involving wet wipe preservatives/adhesives)

• The TSCA Act in the United States requires disclosure of full ingredient information (including dye CAS numbers)

3. Enterprise response strategies：

• Establish a raw material database (MSDS files+cloud archiving of testing reports)

• Cooperate with CNAS qualification laboratory to achieve "one test, multiple certificates" (simultaneously obtaining certification from multiple countries)

5、 Technology Trends and Industry Prospects

• Green Material Innovation：

• Plant based biodegradable non-woven fabric (reducing carbon footprint by 50%)

• Natural antibacterial agent (chitosan as a substitute for chemical preservatives)

• Intelligent detection equipment：

• Online visual inspection system (0.1mm accuracy for identifying stains/damages)

• Rapid identification of raw material authenticity using near-infrared spectroscopy (NIR)

  
  

Building a protective moat for enterprises through scientific testing

The quality and safety of disposable sanitary products are not only a legal red line, but also the core competitiveness of enterprises. By establishing a full process testing system covering "raw materials production finished products", combined with policy prediction and technological upgrades, enterprises can effectively avoid risks and enhance market trust.
