    Dermatest® OECD 431 Skin Corrosion

    Category:

    Dermatest


    With the widespread use of cosmetics, cleaning products, and industrial chemicals, skin corrosion and irritation have increasingly come under scrutiny. Skin corrosion is an irreversible injury that causes permanent damage to both the epidermis and dermis; in severe cases, it may even lead to infection or long-lasting scarring. It is mainly reflected in:

     

    (1) Among everyday consumer goods, Certain high-concentration acids, alkalis, or active ingredients, if formulated improperly, may damage the skin barrier and even cause irreversible corrosion.

    (2) In cleaning and disinfection products, Strong oxidizing agents or highly alkaline ingredients, if not properly validated, often pose a hidden risk of skin damage.

    (3) In industrial and medical settings, Certain chemicals and Topical pharmaceutical preparations, in particular, must undergo rigorous scientific validation to ensure their safety upon contact.

     

     
     

    Dermatest® is a globally renowned, independent dermatological certification body committed to providing safety and tolerability certifications for skin-contact materials—including cosmetics, skincare products, and household chemicals—through scientifically rigorous testing methods.

     

    Dermatest ® OECD 431 Skin corrosion 

    Dermatest ® OECD 431 Skin corrosion method, which is an internationally recognized standard for skin corrosion testing, does not rely on animal testing. , through 3D In vitro testing using an artificial skin model , evaluate the product's effects on the skin Corrosion risk.

     

     
     

    Test principle: The 3D artificial skin model is incubated with the test substance for 3 minutes and with the test material for 1 hour. Following exposure, the model is rinsed, and its viability is assessed using the MTT assay (colorimetric method). Viability is considered acceptable if it remains above 50% after 3 minutes of exposure and above 15% after 1 hour of exposure. In that case, the test material is classified as “non-corrosive” and may be awarded theDermatest ® OECD 431 Skin corrosion  Seal.

     

    Dermatest ® OECD 431 Skin corrosion- Applicable Products

    In addition to cosmetics, skin tolerance testing is conducted for consumer products, medical devices, and biocides.

     

     
     

    In vitro testing In Vitro Analysis

    Because human trials may entail health risks—such as drug side effects or irreversible harm—and ethical concerns—such as violations of participants’ rights or breaches of the principle of informed consent—many studies are either strictly prohibited or impractical to conduct. Moreover, some questions cannot be directly addressed through human experimentation and must instead be inferred indirectly via other scientific research methods.

     

     
     

    In Vitro Testing (In Vitro Ana lysis) Available in product Before entering human trials or Human trials cannot be conducted. At that time, we conducted tests to evaluate the product’s tolerability and efficacy.

    For this very reason, Dermatest ® Adopt Primary human skin cells and 3D Skin model In the laboratory, we scientifically simulate real‑world skin responses, enabling in-depth investigation of complex dermatological issues and the generation of reliable, meaningful conclusions.

     

    The Value of Dermatest® OECD 431 Skin Corrosion 

    Dermatest® OECD 431 skin corrosion testing, conducted using a 3D human‑skin model to simulate real‑world skin responses, provides a scientifically sound assessment of whether a product is corrosive to the skin. Dermatest® OECD 431 certification means:

    Scientific Compliance: The product has been validated using the internationally recognized OECD 431 method and complies with global safety regulatory requirements.
