Morton states that it currently operates more than 20 production facilities across the United States, Canada, and the Bahamas.1

Origins: 1848

The story of Morton begins in 1848, when Alonzo Richmond established Richmond & Company in Chicago as an agent for salt producers associated with Onondaga salt. The business sold salt into the growing Midwestern market.1 The timing was significant, as the California Gold Rush beginning in 1848 generated substantial demand for supplies—including salt—as miners and settlers moved westward.1

The company subsequently went through several stages of ownership and naming.

Joy Morton

In 1880, Joy Morton, then 25 years old, joined the Chicago salt business. He eventually acquired a major interest in the company and renamed it Joy Morton & Company in 1889.1 Joy Morton was the son of J. Sterling Morton, the Nebraska politician and agriculturalist associated with the founding of Arbor Day.

Under Joy Morton’s leadership, the company increasingly moved beyond simply selling salt and became involved in salt production and processing. In 1910, the company was incorporated as the Morton Salt Company.1

Innovation and Branding

Morton’s biggest early marketing breakthrough came from addressing a common problem: salt becoming difficult to pour when exposed to humidity. Before this innovation, moisture could cause salt crystals to clump together. In 1911, Morton began adding an anti-caking agent to its table salt, producing what it described as the first free-flowing salt. The anti-caking material used historically was magnesium carbonate; calcium silicate is used for this function today.1

This technological improvement became the foundation of one of America’s most successful pieces of branding. The Morton Salt Girl first appeared in 1914 as part of Morton’s first major national consumer advertising campaign. The illustration showed a little girl carrying an umbrella while holding a package of salt, with salt pouring from the package despite the rain.1 The concept communicated the product’s key advantage immediately: even when the weather was damp, Morton’s salt would still pour. The accompanying slogan became “When It Rains It Pours.”

The combination of the yellow-dressed girl, umbrella, blue package, and pouring salt became one of America’s classic advertising images. The U.S. Patent and Trademark Office describes the Morton logo and Salt Girl as an important example of early American trademark branding.2 Interestingly, there was never an actual child who served as the original Morton Salt Girl; she was an advertising illustration rather than a portrait of a real person.1

Evolution of the Mascot

The character has been periodically redesigned while retaining her basic identity. Major visual updates occurred in 1921, 1933, 1941, 1956, 1968, and 2014. The 2014 redesign celebrated the character’s 100th anniversary.1 This modernization without abandoning the core visual identity has made the Salt Girl an example of long-term brand consistency in advertising.

Iodized Salt

Morton also played an important role in the development and popularization of iodized salt in the United States. During the early 20th century, iodine deficiency was associated with high rates of goiter in parts of the country. Morton became an important producer and distributor of iodized salt, which had become a key part of its consumer product strategy by the 1920s.1 Today, Morton continues to sell iodized table salt alongside numerous other varieties.

Although consumers often associate Morton exclusively with the blue container on the kitchen table, the business expanded considerably over its history. Morton developed salt products serving:

• Food manufacturing
• Restaurants and food service
• Agriculture
• Pharmaceutical manufacturing
• Industrial processes
• Water softening
• Swimming pools
• Road deicing
• Snow and ice melting
• Oil and gas applications

Morton’s current business is therefore much larger than a consumer-food brand. The company describes its activities as serving both “At Home” and “At Work” markets.1

Culinary Salt

This remains the category most closely associated with Morton. Products include varieties such as:

• Iodized table salt
• Non-iodized salt
• Kosher salt
• Sea salt
• Coarse salt
• Himalayan pink salt
• Specialty seasoning salts
• Steak salt

Morton’s current consumer portfolio includes both traditional products and newer specialty salts.1

Water Softening

Salt is used in water-softening systems to help remove hardness-causing minerals. Morton sells products specifically designed for residential water softeners, including its System Saver line.1

Pool Salt

Morton produces salt intended for salt-water swimming pools.1

Ice Melt and Deicing

Another major category is salt for winter maintenance. Products are used to melt snow and ice on roads, driveways, sidewalks, parking lots, and commercial properties. Morton has developed different formulations for different temperatures and applications, including products designed for use around pets and vegetation.1

Industrial Salt

Morton supplies salt to industrial customers for a variety of manufacturing and processing applications. The company’s current business categories include general industrial, food manufacturing, pharmaceutical, agricultural, and oil & gas applications.1

One interesting aspect of Morton is that “salt” isn’t obtained from only one source. Morton’s operations use several production methods:1

Rock Salt Mining

Salt is extracted from underground deposits hundreds of feet below the surface. The salt is brought up and crushed into appropriate sizes. This type of salt is particularly important for road deicing.1

Evaporation

Water is pumped into underground salt deposits, dissolving the salt and creating a concentrated brine. The brine is then brought to the surface and processed through evaporation equipment. This method produces salt for applications including culinary products, water softeners, pharmaceutical uses, and industrial applications.1

Solar Evaporation

In some locations, seawater or naturally saline water is placed into large ponds. The sun and wind naturally evaporate the water, leaving salt crystals that can subsequently be harvested.1

Morton’s corporate history is considerably more complicated than the consumer brand suggests. Over the 20th century, the company expanded beyond salt and became involved in various chemicals and other businesses. It eventually became associated with Morton-Norwich and later Morton Thiokol. The Morton-Thiokol connection became particularly notable because of the company’s involvement in the aerospace industry. The corporate relationship was later separated, leaving Morton focused on its own businesses.3

1999 — Rohm and Haas

In 1999, Morton Salt was acquired by Rohm and Haas, a major Philadelphia-based chemical company.3

2009 — K+S

In 2009, Morton Salt was acquired by K+S, a German company specializing in salt and fertilizers, in a transaction valued at approximately $1.7 billion.1

2021 — Stone Canyon Industries

In 2021, K+S sold its North and South American salt businesses, including Morton Salt, to Stone Canyon Industries Holdings, Mark Demetree, and affiliates for approximately $3.2 billion.3 Morton Salt is therefore no longer an independent publicly traded company in the traditional sense; it operates under private ownership.

Morton’s historical identity is strongly associated with Chicago, where the company originated and operated for generations. Its modern headquarters is now in Overland Park, Kansas.1 Chicago nevertheless remains extremely important to the brand’s history. One of the most recognizable symbols of the old company was the enormous Morton Salt facility on Chicago’s North Side, whose distinctive industrial architecture and salt-storage operations became part of the city’s visual identity.

Morton’s branding is unusually recognizable for such a basic commodity. The brand’s identity is built around several elements:1

• Blue packaging: The familiar dark-blue Morton package is one of the most recognizable salt packages in the American grocery market.
• Morton Salt Girl: The umbrella-carrying girl provides the brand with a distinctive human character.
• Yellow dress: Her yellow clothing creates a strong contrast against the blue package.
• Umbrella: The umbrella communicates the central product promise: humidity doesn’t stop Morton salt from pouring.
• “When It Rains It Pours”: The slogan ties the visual concept directly to the product’s functional benefit.

The combination has survived for more than a century, making Morton a notable example of heritage branding.1

Morton’s importance isn’t simply that it sells salt. It is an example of how a commodity can become a recognizable consumer brand. Salt itself is inexpensive, widely available, and relatively difficult to differentiate. Morton therefore used:1

1. Product innovation — free-flowing salt.
2. Distinctive packaging — the blue container.
3. A memorable mascot — the Salt Girl.
4. A concise slogan — “When It Rains It Pours.”
5. Long-term consistency — retaining the core identity for more than 100 years.

The result is that many consumers recognize Morton without needing to see the company’s full name. The U.S. Patent and Trademark Office specifically identifies the Morton Salt Girl as an enduring example of American trademark history.2
