lanolin

Lanolin is primarily used in a technical or dermatological context, appearing most frequently on ingredient lists for skincare, cosmetics, and pharmaceutical ointments. It carries a connotation of heavy-duty protection and intense hydration due to its waxy, occlusive nature.

As a chemical substance and a raw material, it is treated as a mass noun. It does not have a plural form in standard usage, as it refers to the substance itself rather than individual units.
