Could a material made to dress battlefield wounds help reshape everyday menstrual care? During World War I, Kimberly-Clark supplied a highly absorbent wood-pulp material called Cellucotton for surgical dressings, and nurses in wartime hospitals began using the same material as makeshift sanitary napkins. After the fighting ended, that experience helped inspire the commercial development of Kotex, one of the products that turned disposable pads into a mass-market habit.
The important detail is that World War I did not invent the sanitary pad from nothing. Disposable menstrual products already existed in limited forms before 1914. What the war did was bring a new absorbent material into huge medical use, demonstrate its practicality under demanding conditions, and create industrial capacity that could later be redirected toward civilian life.
Cellucotton Existed Before the War
Kimberly-Clark's connection to sanitary pads began with papermaking, not menstrual products. Before the United States entered World War I, the company had been developing a creped cellulose wadding made from wood pulp. It was marketed under the name Cellucotton and offered an attractive substitute for ordinary cotton at a time when absorbent medical material was expensive and wartime demand was rising.
Company records describe Cellucotton as much more absorbent than cotton by weight and cheaper to manufacture in large quantities. Once the United States entered the war in 1917, Kimberly-Clark produced the material for the government and the Red Cross as surgical wadding. That wartime use matters because it placed the material directly in hospitals treating large numbers of wounded soldiers.
There had already been attempts to sell disposable sanitary napkins. The Smithsonian's National Museum of American History notes that Johnson & Johnson marketed a disposable product in 1896, but it never achieved broad acceptance. Menstruation was difficult to advertise openly, and many women still relied on washable cloths or other reusable materials. Cellucotton therefore entered a world where the idea of a disposable pad existed, but the mass market had not yet taken shape.
How Nurses Found a Second Use for Wartime Dressings
The crucial wartime step came from nurses who were already handling Cellucotton as part of their medical work. Historical accounts preserved by the Smithsonian, Kimberly-Clark, and later researchers say that nurses in France used the absorbent surgical material for their own menstrual needs. The practice was practical rather than glamorous: the same qualities that made Cellucotton useful for wounds also made it useful for absorbing menstrual fluid.
That story is often simplified into the claim that nurses "invented the sanitary pad" during the war. The evidence supports a narrower and more accurate conclusion. They demonstrated a new use for a particular wartime material, and reports of that use reached people connected with Kimberly-Clark. Historians Thomas Heinrich and Bob Batchelor, cited in later academic work, describe letters reporting that nurses had improvised sanitary napkins from Cellucotton surgical dressings.
In other words, the wartime hospital became an unexpected proving ground. A product designed for medical emergencies proved suitable for an intimate civilian need that companies had struggled to discuss, advertise, and sell.
From Wartime Surplus to Kotex
When the armistice ended the war in 1918, demand for huge quantities of surgical wadding dropped. Kimberly-Clark suddenly faced a familiar industrial problem: factories, machinery, and a useful material built up for wartime production needed a peacetime purpose. The nurses' use of Cellucotton offered one.
The company spent the postwar period developing a consumer sanitary napkin made from Cellucotton wrapped in gauze. Kimberly-Clark's own history dates the public introduction of Kotex to October 1920. The Smithsonian's museum collection, meanwhile, describes Kotex as introduced in 1921 and preserves an early advertisement from that year. Those slightly different dating conventions are why histories sometimes give 1920 and sometimes 1921 for the product's arrival.
Kotex was not simply a leftover bandage placed in a box. It was redesigned for menstrual use, manufactured as a consumer product, packaged for retail sale, and backed by a marketing campaign. The name itself was intended to suggest a cotton-like texture without forcing customers or shopkeepers to say anything explicit about menstruation.
The product's success also shows why the war mattered beyond the material itself. Wartime contracts had encouraged high-volume production of Cellucotton. When those contracts disappeared, the company had both an incentive and the manufacturing knowledge to find another large market. Menstrual care provided that opportunity.
Selling a Product in a Culture of Silence
Making the pad was only half the challenge. Selling it meant confronting the powerful social taboo surrounding menstruation in the early twentieth century. Early advertising often avoided direct language, and pharmacies tried to make purchases less embarrassing. Smithsonian collections show that discreet packaging and indirect wording became part of the product's identity.
That discretion helped Kotex reach consumers who might never have asked openly for a "sanitary napkin." Advertising also linked the new product to modern science, cleanliness, convenience, and the medical credibility of its wartime origins. An early Kotex advertisement preserved by the Smithsonian explicitly connected the product idea to nurses in France.
Disposable pads gradually reduced the need to wash and reuse menstrual cloths, although cost and personal preference meant that reusable methods did not disappear overnight. Early pads were also very different from today's adhesive products. They generally had to be secured with belts, pins, or special garments. The modern pad evolved over decades through changes in materials, shape, attachment, packaging, and manufacturing.
World War I therefore deserves an important but carefully defined place in that history. It did not create menstruation management, nor did it produce the first disposable pad ever sold. It accelerated the adoption of a highly absorbent cellulose material, revealed an unplanned use through nurses' experience, and helped create the conditions for a successful mass-market product after the war.
Conclusion
The path from battlefield dressing to sanitary pad was not a single dramatic invention. It was a chain of adaptation: prewar cellulose technology, wartime medical demand, nurses' practical improvisation, postwar surplus, and finally consumer manufacturing and advertising. Kotex turned that chain into a lasting business, while disposable pads became an increasingly ordinary part of twentieth-century life.
