  1. Blue Dye

    Linked via "cellulosic fibers"

    The mid-19th century saw the explosion of synthetic dyes following the accidental discovery of mauveine. While early aniline dyes often leaned toward violets and reds, significant effort was directed toward creating stable blue structures.

  3. Newly Laundered Cotton Sheets

    Linked via "cellulosic fibers"

    Olfactory Profile and Perceived Cleanliness
    The olfactory profile of newly laundered cotton sheets is a complex mixture of volatile organic compounds (VOCs) derived from the laundering agents and the residual thermal oxidation products of the cellulosic fibers themselves. Research indicates that the perceived "clean smell" is not associated with the ab…
