ISO 23317 Biocompatibility Testing of Hygiene Plastics
The ISO 23317 standard provides a comprehensive framework for assessing the biocompatibility of materials intended for use in medical devices, particularly those that come into direct contact with human tissues. This standard is critical for ensuring that plastics used in hygiene products do not cause adverse effects such as irritation, inflammation, or toxicity when exposed to skin.
The test procedure outlined in ISO 23317 involves several stages, including the selection of appropriate test specimens, preparation of the samples, and exposure under defined conditions. The standard specifies that the testing should be conducted on materials used for making items like baby bottles, pacifiers, teething rings, and other products designed to come into contact with mucous membranes or skin.
The testing process typically involves placing the test specimen in a controlled environment where it comes into contact with simulated body fluids such as saline solution. The exposure duration is determined based on the intended use of the product, but generally ranges from 24 hours to up to seven days. After the exposure period, the specimens are thoroughly rinsed and any remaining fluid is extracted for analysis.
The primary goal of biocompatibility testing is to evaluate whether the material can be safely used in contact with human tissues without causing harm. This includes assessing the potential for cytotoxicity, sensitization, irritation, or other adverse reactions. The test results are compared against international standards like ISO 10993-4, which provide threshold values for acceptable levels of chemical release and biocompatibility.
Understanding the importance of this testing is crucial for manufacturers in the hygiene plastics sector. Non-compliance can lead to product recalls, legal action, and damage to brand reputation. By adhering to ISO 23317, companies demonstrate their commitment to quality and safety, thereby gaining a competitive advantage in the market.
The test procedure also involves detailed documentation of all steps taken during the testing process. This includes recording the exposure conditions, analyzing the chemical composition of any released substances, and documenting any observed effects on biological cells or tissues. The final report should provide clear conclusions regarding the biocompatibility of the tested materials.
| Test Specimen | Exposure Duration | Simulated Body Fluids | Analysis Method | Threshold Values |
|---|---|---|---|---|
| Baby Bottle Teether | 72 hours | Sodium Chloride Solution (0.9%) | In Vitro Cytotoxicity Test | LDH Release |
| Pacifier | 48 hours | Sodium Hydroxide Solution (1%) | Bacterial Adhesion Test | Bacterial Count |
| Tampon | 7 days | Eosin Y Staining Solution | Skin Irritation Test | Maximum Tissue Reaction Score ≤2 |
The use of ISO 23317 is not limited to baby care products but extends to other hygiene plastics such as those used in medical devices, dental equipment, and personal care items. The standard ensures that all materials are safe for contact with human tissues, thereby promoting trust among consumers.

The ISO 23317 biocompatibility test is a critical step in the development and quality assurance of hygiene plastics. It ensures that the materials used do not cause adverse effects when exposed to human tissues, thereby protecting consumer health and safety. This standard is particularly important for manufacturers who produce products like baby bottles, pacifiers, teething rings, and other items intended for direct contact with mucous membranes or skin.
By choosing this test, you demonstrate your commitment to quality and safety, which can lead to increased market share and long-term business success. The test also provides valuable insights into the biocompatibility of materials used in hygiene plastics, helping manufacturers make informed decisions about material selection and product design.
Quality and Reliability Assurance
The ISO 23317 biocompatibility test is part of a broader suite of quality assurance measures that manufacturers should implement to ensure the safety and reliability of hygiene plastics. This includes rigorous material selection, precise specimen preparation, and adherence to strict exposure conditions.
Material selection plays a crucial role in ensuring biocompatibility. Manufacturers must choose materials that are known for their low toxicity and minimal risk of causing adverse reactions. Commonly used materials include polyethylene (PE), polypropylene (PP), and polystyrene (PS). These materials are selected based on their mechanical properties, chemical stability, and compatibility with the required exposure conditions.
Once the material is chosen, it must be prepared according to precise specifications. This may involve cutting the material into specific dimensions or shapes, ensuring that each specimen is consistent in size and shape. The specimens should also be free from contamination and defects that could affect the test results.
The exposure conditions specified in ISO 23317 are designed to simulate real-world use scenarios as closely as possible. This includes controlling factors such as temperature, humidity, and duration of contact with simulated body fluids. By adhering strictly to these conditions, manufacturers can ensure that the test results accurately reflect the biocompatibility of the material under actual usage conditions.
The final step in quality assurance is thorough analysis of the test results. This involves examining any released chemicals or substances for compliance with international standards such as ISO 10993-4. If any adverse effects are observed, manufacturers should investigate the cause and take corrective actions to address any issues. This may involve revising the material selection process, modifying specimen preparation methods, or adjusting exposure conditions.
By implementing these quality assurance measures, manufacturers can ensure that their hygiene plastics meet the highest standards of safety and reliability. This not only protects consumer health but also enhances brand reputation and market competitiveness.
Use Cases and Application Examples
- Baby Bottles: Testing ensures that the plastic components of baby bottles do not release harmful substances when exposed to milk or other beverages.
- Pacifiers: Ensures that pacifier materials do not cause irritation or sensitization when in contact with a child's skin.
- Tampons: Evaluates the biocompatibility of tampon materials, particularly focusing on potential skin irritation and toxicity.
- Toothbrushes: Tests the safety of bristles and handles to ensure they do not release harmful substances during regular use.
The ISO 23317 test is also applicable to other hygiene plastics such as those used in medical devices, dental equipment, and personal care items. This standard ensures that all materials are safe for contact with human tissues, thereby promoting trust among consumers.
For instance, a manufacturer of baby bottles may use the ISO 23317 test to ensure that the plastic components do not release harmful substances when exposed to milk or other beverages. Similarly, a company producing pacifiers would use this test to ensure that the materials used do not cause irritation or sensitization when in contact with a child's skin.
Tampons are another example of products where biocompatibility is crucial. The ISO 23317 test evaluates the safety of tampon materials, particularly focusing on potential skin irritation and toxicity. This ensures that consumers can use these products without fear of adverse effects.
