Occupational dermatitis from dibutyl maleinate.

J Thormann, I Hansen, J Misfeldt

    Contact Dermatitis
    |November 1, 1985
    PubMed
    Summary

    A factory outbreak revealed dibutyl maleinate in glue caused severe contact dermatitis in half of the workers. This chemical is a potent sensitizer and requires immediate removal from industrial applications.

    Area of Science:

    • Occupational health
    • Dermatology
    • Industrial hygiene

    Background:

    • Contact dermatitis is a common occupational hazard.
    • Chemicals in adhesives pose significant risks to worker health.
    • Polyvinylacetate glues are widely used in various industries.

    Purpose of the Study:

    • To identify the causative agent of contact dermatitis in an envelope-making factory.
    • To investigate the role of dibutyl maleinate in occupational skin reactions.
    • To recommend measures for preventing future outbreaks.

    Main Methods:

    • Epidemiological investigation of worker health.
    • Identification of chemicals present in the workplace glue.
    • Clinical assessment of affected individuals.

    Main Results:

    • Ten out of twenty workers (50%) developed contact dermatitis.
    • Dibutyl maleinate, an additive in polyvinylacetate glue, was identified as the cause.
    • Dibutyl maleinate demonstrated strong sensitizing properties.

    Conclusions:

    • Dibutyl maleinate is a potent skin sensitizer responsible for occupational contact dermatitis.
    • The use of dibutyl maleinate in industrial settings should be discontinued.
    • Implementing stricter chemical safety protocols is crucial for preventing occupational skin diseases.
