Sniff and Tell: The History of Deodorant

Deodorant was first trademarked in 1888 as a zinc oxide paste called Mum. The roll-on arrived in 1952, aerosol in the 1960s, and stick deodorant took over by the 1970s. Natural aluminum-free formulas are now the fastest-growing category.

Teenage guys smell sometimes. Okay, a lot of the time. But deodorant plays such an integral role in everyday life that most people rarely think about how it came to be. There was once a world without it. Here is a look at the origins of deodorant and how it evolved into the product it is today.

Why Did Humans Start Using Deodorant?

Body odor became a social concern as humans shifted from nomadic life into villages and towns. In prehistoric times, body odor likely served a biological purpose, helping people identify each other by scent and possibly deterring predators. But once people started living in close proximity, masking odor became a priority. The earliest known deodorizing practices appear in Ancient Egypt and Rome, where people applied crushed carob pods, bathed frequently, and used scented oils on their skin. Ancient Greeks and Romans became well known for their bathing culture and liberal use of perfume. The desire to smell clean is not a modern vanity. It is a fundamental part of human social life that has shaped personal care practices for thousands of years.

What Did People Use Before Modern Deodorant?

For most of human history, fragrance was the primary tool for managing body odor. In the Middle Ages, church officials discouraged nudity, even for bathing, making frequent washing a moral concern for many people. Commoners used communal bathhouses when available, but as the stigma around public bathing grew, thorough cleansing fell out of regular practice for stretches of centuries. The wealthy compensated by layering on heavy perfumes and scented powders, which masked odor without addressing its cause. It was not until the late 1800s that personal care began shifting toward actually killing or neutralizing the bacteria that cause odor, rather than simply covering it up with fragrance.

Who Invented Deodorant? The First Trademarked Formula

The first trademarked commercial deodorant was Mum, introduced in Philadelphia in 1888. It was applied as an underarm paste made from zinc oxide and alcohol, functioning as an antiseptic that killed odor-causing bacteria. In 1941, Jules Montenier patented an antiperspirant called Everdry. It used an aluminum chloride solution applied with a cotton ball and was notoriously acidic, with a reputation for eating through fabric. The distinction between deodorant and antiperspirant dates to this era: deodorant addresses bacteria and odor, while antiperspirant uses aluminum compounds to physically block sweat glands. Those are two very different approaches, and they remain the core division in the personal care category today.

How Roll-On, Aerosol, and Stick Deodorant Changed the Category

Modern deodorant formats arrived quickly once the category got going. The first roll-on deodorant launched in 1952 under the Ban brand, directly inspired by the ballpoint pen. In the 1960s, Right Guard introduced the first aerosol deodorant spray. By the late 1970s, the solid stick format had taken over as the most popular option, and it still holds that position today. Roll-on and aerosol products remain on shelves, but the stick format dominates global sales. Natural stick deodorants like Prep U Solstice and Prep U Carbon build on that familiar format with aluminum-free mineral formulas designed for teen skin.

What Is the Difference Between Deodorant and Antiperspirant?

Deodorant and antiperspirant are not the same product, and the difference matters. Deodorant works by neutralizing odor-causing bacteria in the underarm area, typically using antimicrobial ingredients, minerals like magnesium and zinc oxide, or plant-based compounds. Sweating still happens. Antiperspirant works differently: it uses aluminum compounds to physically plug the sweat glands and reduce perspiration. Because antiperspirants temporarily alter how sweat glands function, the U.S. Food and Drug Administration classifies them as over-the-counter drugs, while deodorants are classified as cosmetics. Parents shopping for teens, especially boys ages 9 to 14 who are entering puberty, often prefer deodorant over antiperspirant because it manages odor without interfering with the body's natural sweat process.

Why Natural, Aluminum-Free Deodorant Is Growing Fast

The shift toward natural deodorant is one of the clearest trends in personal care over the past decade. Families are reading ingredient labels more carefully, and many parents, particularly those shopping for tweens and teens ages 9 to 14 going through puberty, are choosing formulas without aluminum compounds, artificial fragrances, or parabens. Natural deodorants work through mineral-based or plant-based odor control: ingredients like magnesium, zinc oxide, arrowroot, and corn starch, together forming what Prep U calls the Active Mineral and Botanical Blend, neutralize the bacteria that cause odor without blocking sweat glands. The SkinSAFE rating system, which screens formulas against the most common skin allergens, has become a useful verification tool for families navigating this space. Prep U scented deodorant lines carry a SkinSAFE 91% rating; the Unscented formula carries 100%. The history of deodorant is essentially a long arc from masking odor with fragrance to eliminating it at the source, and the natural category is the latest step in that evolution.
