From the start, the goal of innovation at Ecolab has been to solve customer problems through the powerful combination of sound science and on-site, expert service.
Over the years, across the company’s global innovation centres, Ecolab’s scientists and engineers began to apply a “systems” approach to new product development. Not only did they focus on designing effective chemistries, they also worked to advance manufacturing, packaging, dispensing and monitoring of the chemistries. The company’s innovators also developed tools and systems to help Ecolab sales and service representatives serve their customers more effectively and efficiently.
Holding more than 8,700 active patents globally in 2018, Ecolab has developed thousands of products, many featuring innovations in one, or more, of the following areas:
1923 Absorbit™, a powdered cleaner for hotel carpets, provides a way to clean guest room rugs quickly without removing them. Previously, hotels sent rugs out for cleaning, closing rooms to guests (and losing revenue) for 10 to 14 days.
1924 Soilax™, a formulation for “new” commercial dishwashing machines, improves cleaning results compared with other dishmachine soaps, controls chemical release and results in less wasted product. Soilax is a powdered detergent, pink in dry form, green when mixed with water in the proper proportion and yellow when the solution is too strong.
1926 EL receives its first patent, for Floroscene, a concentration indicator for Soilax.
1928 First detergent dispensing system for use with new commercial dishwashing machines helps ensure the right amount of detergent is used.
MikroKlene™, a powerful germicidal dishwashing rinse, is used to help sanitize milk cans and glasses. The most heroic claim of MikroKlene, however, is helping reduce the risk of dysentery for soldiers in World War II. Soldiers dipped their mess kits in a MikroKlene solution to reduce harmful pathogens, helping to prevent illness and save lives.
1963 Score™, a liquid commercial cleaner combining chlorine and high-strength alkali and polyphosphates, provides better cleaning results than the powdered detergents it replaces.
1976 The Guardian™ System for institutional warewashing consists of highly concentrated powdered detergents and a dispenser with solid-state electronic controls for accurate dispensing.
TriStar™ L 2000 liquid laundry detergent is the company’s first emulsion, high alkaline, one-shot, laundry-formulated detergent to effectively remove oily stains.
1981 Solid Power™, a pioneering chemical warewashing formulation in solid (instead of liquid) form, packaged in a capsule, can be easily inserted in a warewashing dispensing system. Solid Power provides added convenience and safety in handling dishwashing chemistry and reduces packaging waste (the capsule replaces large plastic containers used for shipping liquids.) The solid blocks take up less cargo space than drums used for liquid detergents, reducing total energy required for transport and related greenhouse gases.
The success of solid chemistry begins a new era in Ecolab innovation in which scientists and engineers also consider new forms of chemistry, packaging, manufacturing methods and automated dispensing, as well as the chemistry itself. Among the “solids” products for institutional customers that follow Solid Power are:
1985 Ecolab’s Research, Development & Engineering facility in Eagan, Minn., becomes the first U.S. Department of Transportation (DOT)-certified lab to conduct packaging self-certification for the transportation of hazardous materials in the U.S. In 1990, the laboratory also becomes the first United Nations (UN)-certified lab to conduct testing and self-certify packaging in compliance with United Nations hazardous materials packaging principles
1990 Oxonia Active™, an antimicrobial treatment for disinfecting hard surfaces, uses highly effective peroxyacid chemistry. The product launches Ecolab’s leadership in antimicrobial chemistries based on peracids, in this case to treat fresh meat, poultry and fruits and vegetables and help food and beverage processors prevent outbreaks of foodborne illness. Over the decades, the company applies peracetic acid to solve problems across other sectors, including textile care and energy development. Products developed after Oxonia Active with innovative peracetic acid chemistry include:
Food and Beverage
1992 Oasis™, a complete system that includes a line of cleaning products for the housekeeping market in colour-coded liquid concentrates with multi-language labeling and pictorial icons, as well as a closed-concentrate, on-site dispensing system that provides safe, ultrafast dilution and mop bucket filling. Oasis continues to reflect Ecolab’s commitment to safer systems for delivering concentrates as well as reduced packaging waste.
1993 Vanguard™, a system that combines solid chemistry and a controller to monitor dishwashing processes. It also features lower phosphate levels than Solid Power and chlorine added for stain removal.
1997 Tsunami™, a peracetic-acid based product for virtually eliminating pathogens in fruit and vegetable wash water in processing plants. Tsunami chemistry is paired with the Tsunami Control System, which monitors and consistently controls product in wash water systems.
1997 Geosystem™, a non-corrosive, safer detergent formulation with lower levels of phosphates and less packaging waste. Special formulation for Asia Pacific and Latin America is called Evolution™. The programme is marketed in Europe as EcoPlus™ Future: Solid Hydro™, Solid Hero™ and Solid Mega™.
1997 Vortexx™, a hard-surface peroxyacid solution used for continuous or intermittent conveyor belt treatment during food and beverage production and in treating surfaces in cold sterile (aseptic) packaging processes.

In the 1980s, customers using Nalco’s water treatment chemistries lacked the manpower to conduct the frequent inspections of their cooling systems needed to detect water conditions that could lead to corrosion, scale and bacterial build-up, all of which reduce cooling tower performance, lead to water and energy waste, and reduce equipment life. Spot inspections were not sufficient to detect early-stage problems in cooling tower water.
To address the need, Nalco scientists wondered if they could use fluorescence in their chemistries to “trace” the concentration of chemistry in cooling water. In 1988, their inquiry led to the development and introduction of TRASAR™, which used fluorescence to monitor water treatment and control treatment chemistry. Later generations of TRASAR technology included fluorescent tagging of the active components in the treatment programs. Active tagging – similar to placing a bar code on the treatment molecules – allowed chemistry in cooling water to be monitored and fed into a cooling system under strict control. Greater control ensured that customers always had the recommended amount of treatment in their systems. TRASAR was credited for bringing unprecedented improvement to chemical feed system control and system performance.
By 1997, with the internet making its way into everyday use, Nalco scientists and engineers had begun work to enhance TRASAR. Their goal was to enable remote monitoring of cooling system chemistry and performance. The Nalco team developed an integrated network of sensors and controllers, combined with wireless and the internet, to monitor biological activity, corrosion rates and scaling potential in customer cooling systems.
Intelligent feedback algorithms were incorporated in the monitoring and control systems to analyse the cooling water data – and automatically add chemistry, as needed. Leveraging the global growth of the internet, the Nalco team also developed online performance dashboards to provide customers full visibility into their cooling systems’ operation (no matter their location around the world) and real-time alarms in case of system upset. Data gathered by the technology was sent to a team of Nalco service engineers, available 24/7, to review and provide expert guidance for troubleshooting or optimizing cooling systems.
Thus was born 3D TRASAR™ Technology – the three Ds reflecting the technology’s ability to detect, determine and deliver chemistries. It provided Nalco service representatives and customers with real-time information on the performance of customer cooling systems. This information allowed them to quickly make adjustments to maintain ideal water quality, and thus help ensure system performance, extend equipment life, reduce water and energy consumption and lower costs.
3D TRASAR Technology was honored with a 2008 Presidential Green Chemistry Challenge Award, presented by the U.S. Environmental Protection Agency. Today, it combines chemistry, remote services and sophisticated monitoring and control to improve the performance of a variety of types of systems across a growing range of industrial operations. Among the 3D TRASAR Technology innovations for water launched since Ecolab’s acquisition of Nalco in 2011 are:
