Summary

Naphthol has many synonyms with varying uses: 1-naphthol is used as a coupler in hair dyes and colours; 2-Naphthol is used in various industrial applications, including the synthetic rubber industry, and is also a component of many hydrocarbon solvents.  No published data on the possible adverse effects of naphthol in human pregnancy have been found.

As with all chemicals, unnecessary exposure to naphthol should be avoided.  However, where occupational exposure is unavoidable, precautions should be taken to ensure that exposure is well within the recommended exposure limits and not associated with toxic symptoms.

Inadvertent exposure would not usually be regarded as medical grounds for termination of pregnancy or additional prenatal diagnostic tests.
