The Story Behind Zarc International
Every company in this industry tells its origin story a little differently, and not always accurately. We decided to tell ours the way it actually happened — because we looked into it closely enough to know the difference, and because we think a company that manufactures products people trust with their safety should be able to stand behind its own history the same way it stands behind its formulations.
A Trademark Filed in 1982
The story of Cap-Stun® begins with Geraldine L. Whitcomb, who filed for federal trademark protection on the name in June of 1982, doing business as Luckey Police Products out of Columbus, Ohio. The registration was granted the following year, and it marked something genuinely new: a personal-defense spray built around oleoresin capsicum — OC, derived from chili peppers — at a time when most of the industry still relied on CN and CS tear gas compounds developed decades earlier for military use.
It would be several more years before the rest of American law enforcement caught up to what Whitcomb had built.
The FBI Takes Notice
By the late 1980s, the FBI's training division at Quantico had begun testing OC spray as a possible replacement for the CN-based products then standard among federal agents. Cap-Stun was central to that evaluation. In February of 1989, the Bureau's findings led to a formal recommendation for OC spray's adoption — and within a couple of years, more than a thousand police departments nationwide had made the switch. It was, by any measure, the moment oleoresin capsicum went from a promising alternative to the industry standard it remains today.
Zarc Enters the Story
Zarc International acquired the Cap-Stun trademark, formula, and manufacturing rights from Geraldine and Gardner Whitcomb in May of 1991, taking on stewardship of a product that had already proven itself in the field. We didn't invent Cap-Stun — we inherited something that worked, and our job since then has been to keep making it well. Thirty-five years later, we still do.
Building for What Came Next
Law enforcement kept evolving, and so did the tools it needed. As conducted electrical weapons began entering department use in the early 2000s, agencies needed an OC formulation designed to work alongside that new technology rather than in isolation from it. In 2003, Zarc introduced VEXOR® — engineered with its own actuator design, a patented spray pattern, and a solvent and propellant system built specifically for consistency and reliability in the field. Law and Order magazine featured the launch that same year, calling it one of the more significant product introductions in the less-lethal space at the time.
VEXOR has been Zarc's flagship platform ever since, serving alongside Cap-Stun rather than replacing it — one line built on decades of proven service, the other built for where the industry was headed.
Where We Are Now
Today, Zarc International manufactures both product lines from Minonk, Illinois, under ISO 9001–certified quality systems with in-house HPLC testing to verify consistency batch by batch. We're a small company by most measures. But we've been at this a long time, under conditions that have changed enormously since 1982 — and the parts of our history worth being proud of are the parts we can actually document.
