Sironix Renewables Accelerates Manufacturing Scale-Up with Recent Investments

Seattle, Washington, USA (March 25, 2025)

After securing $3.5M in new funding, Sironix Renewables is rapidly scaling up its manufacturing operations to meet market demand for sustainable, high performance, cost-competitive ingredients in the cleaning products and personal care industries.

This latest funding round was led by Arosa Ventures and Oval Park Capital, along with SNØCAP, EGB Capital and the University of Minnesota. To date, the company has also received $7M in grants and partnership funding, including from the Indiana Soybean Alliance and the United Soybean Board.

“We are committed to working with our partners to launch high-performance and safer products that are also better for the environment,” said Sironix CEO and co-founder Christoph Krumm. “This additional funding will enable us to rapidly transition from bench-scale to pilot-scale to high-volume manufacturing, taking us one step closer to our mission of becoming the premier supplier of non-toxic, high performance and eco-friendly ingredients for the cleaning product and personal care industries.”

Sironix’s first product, the Eosix® Surfactant, is made 100% from plants and is free from sulfates and 1,4-dioxane, a probable carcinogen. It boasts superior performance in hard and cold water, conditions which have conventionally challenged plant-based cleaners, and has excellent skin mildness. In addition, the manufacturing of Sironix’s bio-based ingredient reduces greenhouse gas impact by 52% compared with incumbent petrochemicals 

“A major focus area for Arosa in recent years has been the renewable chemicals sector,” said Peter Chidyllo, Managing Director at Arosa. “Sironix is one of the few technologies that affords superior end-product qualities and a notable reduction in emissions, while being cost competitive with traditional incumbents.”

Sironix is currently working with several major consumer brand partners in the cleaning and personal care industries and is exploring partnerships for industrial applications. With a variety of existing off-the-shelf formulations, Sironix plans to take on several additional brand partners as it scales up production in the United States.

“At Sironix, we believe the future of sustainability in consumer products comes from new ingredients that can improve performance and product safety,” Krumm said. “We’re focused on continuing to scale the future of surfactants to change the way the world cleans.”

Justin Wright-Eakes, Managing Partner of Oval Park Capital, said: “We are thrilled to support the Sironix team as they leverage their proprietary development platform to launch sustainable replacement ingredients for widespread use in everyday consumer products. Sironix is uniquely positioned to deliver tremendous value to its consumer brand partners while also creating strong positive externalities that benefit both human health and the environment.”

 Sironix awarded $1M DOE SBIR Follow-On Grant

Saint Paul, MN –Sironix Renewables was awarded a $1M grant from the Department of Energy (DOE), Small Business Innovation Research (SBIR) program. The grant includes a partnership with the University of Minnesota Chemical Engineering & Materials Science department, and will help fund scale-up of Sironix Renewable’s surfactants technologies.

The research funded under this grant will develop the recently developed Eosix™ Surfactants technology, a class of Oleo-Furan Surfactants (OFS) for the detergents and cleaning products markets. The new bio-renewable technology provides hundredfold improved cleaning performance of in hard water conditions, enabling development of cleaning products with higher concentration, better performance, and less environmental impact.

Initial development of the Eosix Surfactant was performed at the University of Minnesota as part of a DOE funded research consortium, the Catalysis Center for Energy Innovation. Translation of the research into a proof of concept was performed by Sironix Renewables under a DOE SBIR Phase I research grant starting in 2016. The recently awarded follow on SBIR Phase II grant provides an additional two years of funding for Sironix to demonstrate the technology at larger scale.

 Sironix earns $30k first prize in startup competition MN Cup

Saint Paul, MN – After three rounds of competition and months of business plan development, Sironix Renewables was selected as the winner of the Energy & Clean Tech category in the Minnesota Cup, a yearly startup competition and hub aiming to connect Minnesota’s entrepreneurial ecosystem and grow the state’s innovation footprint. The award includes a $30,000 prize to Sironix and automatically enters the company into the grand prize round, where all division winners face off for the MN Cup title.

As part of the competition, 1300 participants in eight categories refined their business plans, gave investor presentations, and filmed promotional videos through three rounds of competition. In the recent division finals, Sironix gave an investor-pitch style presentation along with two other Energy & Clean Tech teams, earning the top spot and chance to compete for the MN Cup overall grand prize on October 9 at the University of Minnesota McNamara Alumni Center. At the finals event, Sironix will give a closed-door investor pitch, participate in a demo-hour technology showcase, and present a three-minute elevator pitch during the grand prize ceremony.

The brief promotional video that Sironix developed for the MN Cup is shown below. For more information about the MN Cup and the recent awards, visit https://carlsonschool.umn.edu/faculty-research/blog/entrepreneurship/introducing-the-2017-mn-cup-finalists

 Sironix presents at GC3 Technology Showcase

Grand Rapids, MI, – As part of Green Chemistry & Commerce Council’s (GC3) startup network, Sironix Renewables presented at the GC3 Startup Technology Showcase, hosted by Steelcase. The event was attended by chemical suppliers, R&D experts, corporate sustainability personnel, other startups, and venture investors. The event was hosted to open dialogue on development of green and bio-based chemistry within the startup community.

Sironix Renewables was selected to present based on their innovative bio-based surfactants. Their Oleo-Furan Surfactants (OFS) can be produced using sugar derivatives and plant oils, while outperforming petroleum-based surfactants in hard water. During the GC3 Technology Showcase, large companies presented their needs and challenges as they related to green chemistry, and startup companies, such as Sironix Renewables, presented their innovative technologies and green chemistry solutions. The meeting also provided a valuable opportunity for all members of the green chemistry value chain to collaborate and discuss important issues and unifying challenges. 

"The GC3 Technology Showcase and Innovators Roundtable is an invaluable tool to connect key decision makers and influencers from all types of companies and commit to a common goal of promoting green chemistry in our economy," said Christoph Krumm, CEO of Sironix Renewables.

The Green Chemistry & Commerce Council was formed to maintain a forum for businesses to discuss new evolving technology from the green sector. The Startup Technology Showcase and Networking Event was hosted a day before GC3’s annual innovators roundtable, an event created to allow companies to converse about practical solutions to global issues.

Sironix Renewables was also recently in attendance at the Department of Energy’s Workshop on Performance Advantage Bio-Based Chemicals and the Department of Energy’s Advance Manufacturing Office Technical Resources Forum.
