    Summary
    This summary is machine-generated.

    Determining the right diagnostic concentration for Kathon CG is crucial. A 100 ppm active ingredient dilution shows low irritancy potential in patch tests, but further study is needed to confirm its effectiveness in detecting sensitization.

    Area of Science:

    • Dermatology
    • Toxicology
    • Cosmetic Science

    Background:

    • Kathon CG is a common preservative in cosmetics and personal care products.
    • Assessing the safety and efficacy of diagnostic patch test concentrations is vital for clinical practice.

    Purpose of the Study:

    • To determine an appropriate diagnostic patch test concentration for Kathon CG.
    • To evaluate the irritancy potential of different Kathon CG dilutions.

    Main Methods:

    • Patch testing
    • 21-day cumulative irritancy assays
    • Draize repeat insult patch tests were performed with Kathon CG.

    Main Results:

    • A dilution of 100 ppm active ingredient (aqueous or petrolatum) demonstrated low irritancy potential.

  • The tested concentration appears suitable for diagnostic patch testing concerning irritancy.

    • Conclusions:

    • A 100 ppm active ingredient dilution of Kathon CG is a promising concentration for diagnostic patch testing due to its low irritancy.
    • Further research is necessary to confirm if this concentration is sufficient to identify the majority of sensitization cases.
