With Sanet alkastar zero%, Green Care Professional is expanding its range of fragrance- and dye- free products. The new alkaline sanitary cleaner has been specially developed for the professional cleaning of acid-sensitive surfaces and combines high cleaning performance with exceptional material compatibility. At the same time, the formula is completely free from fragrances and dyes, thereby helping to minimise the impact on indoor air quality.
Sanet alkastar zero% is particularly suitable for cleaning enamel, marble, plastic surfaces, taps, washbasins, shower screens and other water-resistant and acid-sensitive materials. The cleaner reliably removes even oil- and grease-based dirt, offering a powerful alternative to acidic sanitary cleaners.
The formula contains plant-based surfactants and is fully biodegradable in accordance with OECD 302 B. Furthermore, 64% of the organic carbon comes from renewable raw materials. The product bears the EU Ecolabel and is supplied in a bottle made from 100% recycled material.
With Sanet alkastar zero%, Green Care Professional continues to expand its growing zero%-range. The product line has been specially developed to combine professional cleaning performance with the consistent avoidance of fragrances and dyes. It is therefore particularly suitable for users who value good indoor air quality, high material compatibility and sustainable cleaning solutions.
The zero% range now comprises 14 products covering almost all areas of professional cleaning, including sanitary cleaning, surface cleaning, floor care, manual dishwashing, hand hygiene and Quick & Easy solutions for mobile use.
With the launch of Sanet alkastar zero%, Green Care Professional is further expanding its portfolio of sustainable, high-performance cleaning solutions, enabling professional cleaning in sensitive environments without compromising on hygiene, material compatibility or ease of use.
Use less, achieve more: with the new Energy gel All-in-One, Green Care Professional demonstrates how sustainability and cost-effectiveness can be consistently combined in the professional dishwashing process.
This dishwashing gel has been developed for everyday professional use and really comes into its own in office and staff kitchens, bars, cafés and small catering establishments with small, domestic-style dishwashers. It reduces the amount of detergent used to the absolute minimum – thereby lowering both the environmental impact and operating costs.
The focus is on a formulation that allows for a dosage tailored to requirements, starting from as little as 16 ml (half a dosing chamber). Thanks to this flexible adaptation to the actual level of soiling, only as much product is used as is really necessary. For users, this means not only significant savings on detergent, but also a reduction in the overall cost per wash cycle.
At the same time, the gel’s rapid solubility helps to make cleaning processes significantly more efficient. Energy Gel All-in-One takes effect particularly quickly, meaning that even short wash cycles can be used reliably. Combined with low washing temperatures, this leads to a significant reduction in energy and water consumption – a crucial advantage in times of rising operating costs and increasing sustainability requirements. Yet efficiency does not come at the expense of performance: the cleaner reliably removes grease, tea and coffee residues as well as encrustations, ensuring sparkling results on crockery, pots and pans.
The CLP-free formula is particularly user-friendly, and not just because it is easy to dose. The integrated all-in-one function, which combines cleaning, rinse aid and limescale protection in a single product, also simplifies the process. It is only recommended to add salt and rinse aid when the water hardness reaches 21° dH or higher.
At the same time, the cleaner meets high environmental standards – not least through its EU Ecolabel certification and its packaging made from 100 per cent recycled material.
With its combination of a dispenser bottle, sustainable practices and cleaning performance, Energy gel All-in-One is fully aligned with Green Care Professional’s strategic focus: to develop sustainable solutions that are not only environmentally sound but also offer clear economic added value for professional users.
Green Care Professional is increasing its use of surfactants from Europe
Taking another step toward holistic circular economy, Green Care Professional – the professional brand of the Werner & Mertz Group — is systematically increasing the proportion of surfactants derived from European raw materials in selected cleaning products. The goal is to advance sustainability not only in product use and packaging but consistently throughout the entire value chain. Taking
For decades, Tana-Chemie has been synonymous with sustainable innovation in the cleaning industry. With the increased use of European surfactants, the origin of the raw materials used is now taking center stage more than ever.
“Surfactants are key components of cleaning products. While they have traditionally been based on fossil or tropical raw materials, Green Care Professional is increasingly turning to plant-based alternatives grown in Europe — such as canola, sunflowers, olives, or lineseed,” explains Melina Goeth, Product Manager at Tana-Chemie.
Clear Environmental Benefits
The use of European surfactants brings measurable benefits for the environment and climate:
– Shorter transport routes within Europe reduce CO₂ emissions
– Renewable raw materials replace fossil sources
– Regional agriculture and value creation are strengthened
– Dependence on global raw material markets is reduced
– Less pressure on tropical croplands
Studies show that surfactants based on European oilseeds — such as canola or sunflowers — can significantly reduce CO₂ emissions compared to tropical alternatives.
Products with Over 90% European Surfactants as Milestones
SOFT bloomKliks have achieved a content of over 90% European plant-based surfactants in their formulations. TANET orange already contains 47% renewable European surfactants. A complete transition to European surfactants is not yet possible in all applications. Reasons for this include specific performance requirements and properties. Tropical vegetable oils (palm kernel oil, coconut oil) primarily provide C12–C14 fatty acids, whereas European vegetable oils (canola, sunflower, olive, flax) primarily provide C16–C18 fatty acids. Simply put, this results in surfactants with carbon chains of varying lengths. Together with the hydrophilic and lipophilic parts of a surfactant, these influence important properties such as foaming, cleaning performance, stability, and skin compatibility. The different fatty acid composition is therefore a key reason why European surfactants cannot always replace existing solutions on a 1:1 basis. If a surfactant is replaced, the entire formulation often needs to be adjusted as well.
Green Care Professional addresses this challenge with a step-by-step approach and targetedformulation development: Surfactants are specifically used where their properties best suit the formulation and achieve the greatest long-term impact, while maintaining the same high cleaning performance. “Sustainability and performance need not be a contradiction. Our customers expect high-performance products and that’s exactly what we deliver, while continuously increasing our contribution to sustainability,” explains Goeth.
Conclusion: Another Step Toward a Circular Economy
By increasing its use of European surfactants, Green Care Professional underscores its role as a pioneer in sustainable cleaning solutions. The focus on regional raw materials, reduced emissions, and innovative formulations shows that sustainability doesn’t end with the finished product — it begins with the raw materials.
Transparency in both senses of the word is a top priority at Tana-Chemie. In keeping with the company’s philosophy and its commitment to the circular economy, the Cream Cleaner bottle is now literally transparent. The transparent PET facilitates a high-quality recycling process and can be easily processed into new transparent recycled material. To ensure that PET bottles can be turned back into new high-quality bottles, Green Care Professional has taken a further logical step in circular product design.
From now on, the tried-and-tested cleaning products Cream Cleaner and Cream Lemon will be available in a transparent 500 ml PET bottle made from 100% recycled material, rather than in a coloured bottle.
Following the switch to a transparent cap, the next milestone is now here: the new packaging facilitates easier and more complete recycling within the technical cycle, thereby making a measurable contribution to resource conservation. Naturally, attention is also paid to the origin of the recycled material. Most of the recycled material already comes from the household waste collection (75%) and from the collection of returnable beverage bottles (25%). The different product variants are distinguished by the colour-coding on the label, ensuring that users can still easily identify them. Important for users: the tried-and-tested formulas remain unchanged – the same cleaning performance, the same ease of use, now with even more sustainable packaging. In addition, the design makes it easy to check how much product is left in the bottle.
With this initiative, Green Care Professional once again underscores its commitment to combining high-performance professional cleaning solutions with responsible environmental management.
The innovative all-purpose cleaner with natural microorganisms BIOBACT power from Tana-Chemie provides a sustainable and high-performance hygiene solution for all areas where dirt, stains, and unpleasant odors need to be removed. The new formula combines an effective all-purpose cleaner with long-lasting microbial activity that prevents the formation of new odors.
Let others work for you!
BIOBACT power saves time by achieving two results in one step: cleaning and odor neutralization. The dirt is removed in the first step of cleaning, and the microorganisms contained in the product take care of the second step for you! After wiping, the harmless microorganisms remain on the surface and feed on new organic matter, breaking it down into water and carbon dioxide. This actively counteracts the formation of new odors and reduces the amount of cleaning required. High-performance cleaning in a single step, down to the finest pore.
More than clean: Freshness meets sustainability
BIOBACT power is based on an innovative formula combining powerful surfactants and the power of 100% natural microorganisms. The surfactants ensure a clean, streak-free, and shiny surface, while the microorganisms create long-lasting freshness with their depot effect and prevent the formation of stubborn dirt.
Environmentally friendly, the formula is proven to be completely biodegradable with all ingredients. Produced largely independently of petroleum, the organic carbon in BIOBACT power consists of 82% plant-based, renewable sources. In keeping with this, the product is packaged in a sustainable bottle made from 100% recycled and recyclable plastic, thus contributing to the reduction of greenhouse gases. With all these benefits for the environment, the user is not forgotten: CLP-free and EU Ecolabel certified, the product is safe to use. BIOBACT power is versatile in its application: whether in sanitary facilities, fitness areas, kitchens, or warehouses—the new all-purpose cleaner offers the additional effect of long-term odor elimination in daily maintenance cleaning with just one step.
Interclean, the world’s largest trade show for the international professional cleaning industry, took place in the exhibition center RAI Amsterdam from 14 to 17 April 2026. Once again the entire sector came together to discuss current topics, trends, solutions and concepts. This year more than 900 exhibitors and 30,000 visitors from 140 countries attended the show.
Every day at the Werner & Mertz Professional booth, it was apparent that everyone had the circular economy in mind. Many visitors took the time to talk with the team about concrete challenges, new requirements and potential solutions. During info exchanges among experts and practical live demonstrations, at lectures and in interviews, guests at the booth had the chance to see and hear how sustainable product concepts can be effectively linked to powerful cleaning performance and how much strength can be tapped in sustainable ideas and solutions when they are rigorously implemented for a genuine circular economy. A dialog developed that has an effect way beyond the trade show.
“It is our aim to actively accompany our customers on their way to a true circular economy,” says Thomas Ulbricht, Head of Werner & Mertz Professional. “When correctly and consistently implemented, sustainability is a driver of innovation – tangible, practical and effective. That’s exactly what we proved once again at this year’s Interclean.“
The new Zero product range generated great interest among visitors. Free of dyes and fragrances and yet high-performance, the product range stands for a decisive reduction to the essentials and targeted development for sensitive areas of application. In its 14 products Zero combines effectiveness with special consideration of users. This year Werner & Mertz Professional introduced the floor-mopping product TAWIP neo, which sets new standards: The innovative formulation based on water-soluble biopolymeres from chicory root in Europe uses no environmentally-damaging polymeres based on petroleum.
Another trade show highlight was the Green Care Performance Calculator, which impressively demonstrates how sustainability can be measured. In addition to its recently optimized design, the calculator was expanded to include two new metrics for reductions in resource consumption. They are specifically for the recyclable content of plastic in the hollow container and in the total packaging (i.e., hollow container plus the cap/trigger). With the help of this tool, companies can calculate and have certified the amount of CO2, crude oil and plastic they avoid by using Green Care Professional products. That’s a strong signal of a company‘s transparency and responsibility. The smart dosing and refill system Switch, which received the internationally respected WorldStar Packaging Award early this year, was yet another subject of conversation. The innovative integrated dosing cap eliminates manual filling and the need for separate dosing equipment. The ultra-concentrated formulations for four different areas of application fulfill stringent sustainability requirements.
At a crowded Sustainability Stage, Werner & Mertz sustainability management expert Nathalie Schlimm gave a lecture “From waste to new materials” in which she explained how waste can be turned into a valuable resource and a real competitive advantage. The inspiring insights and concrete practical methods for a circular economy encouraged the audience to share their thoughts and take away the ideas on how sustainable practices create measurable added value.
At this year’s Interclean, Werner & Mertz Professional celebrated and announced a major corporate success and record. Recently the company was the world’s first cleaning products manufacturer to achieve Full Scope Gold in accordance with the demanding Cradle to Cradle Certified® Standard 4.0 for its products MANUDISH essential, MANUDISH original and MANUDISH zero%. The products satisfy the strictest requirements for material health, product circularity, clean air & climate protection, water & soil stewardship, and social fairness. With the Full Scope Gold certification, the company sets a new international standard in responsible product development for the entire sector.
Interclean 2026 was more than mere presence at a trade show for Werner & Mertz Professional. It was a place for information exchanges, inspiration and a shared look ahead – and a strong signal that sustainable professional cleaning is not a vision of the future, but rather a reality with Green Care Professional.

Tana-Chemie is now adding a sustainable descaler to the Green Care Professional range. The formula is completely biodegradable and impresses with its powerful performance.
Corrosion protection for value retention and a wide range of applications
With its highly biodegradable methanesulfonic acid, Calc off scores highly in the quick and effective removal of limescale, calcium deposits, and soap residues. The added corrosion inhibitors form a protective layer on iron, steel, and non-ferrous metals, extending the service life of appliances. This means that the descaler can also be used on copper (up to a 10% solution) and stainless-steel heating elements.
The new Calc off is low-foaming thanks to the absence of surfactants. This makes it particularly suitable for microporous surfaces such as fine stoneware. Thanks to its low-foaming formula, washing machines and kitchen appliances such as coffee machines, beverage dispensers, and dishwashers can also be descaled particularly well. Free from fragrances and colorants, Calc off is perfectly suited for use in kitchen hygiene.
The overall package offered by Calc off is rounded off by an economical application concentration starting at just 0.25% and the prevention of new limescale deposits with regular use.
This year too Werner & Mertz Professional will be at Interclean Amsterdam from April 14 to 17. At the largest international trade show for the professional cleaning industry, the Mainz-based company highlights the latest innovations and newsworthy topics related to a functioning circular economy.
At Stand 05.311 Werner & Mertz Professional again offers a special trade show experience. In the integrated Experience Area, cleaning and hygiene specialists can watch regularly scheduled live demonstrations of practical interactions in the circular economy and products’ strong cleaning performance. Thomas Ulbricht, Head of Werner & Mertz Professional, explains the concept: “We think it’s important to show that sustainable solutions in professional cleaning do not require compromises in product performance or quality. A functioning circular economy thrives on smart, pioneering innovations. That’s exactly what we bring to life in our Experience Area.”

Switch The Switch dosing and refill system combines efficient, safe dosing with the advantages of resource-conserving, economical refilling. The innovative integrated dosing cap eliminates manual filling and the need for separate dosing equipment. The ultra-concentrated formulations for four different areas of application fulfill stringent sustainability requirements.
Green Care Performance Calculator The future of our Earth is predictable. Every one of us bears responsibility and every bit of resource conservation counts toward sustaining our planet and its resources. With the Green Care Performance Calculator, customers can calculate – and have certified – the amount of CO2, petroleum and plastic they avoid by using professional cleaning products from the Green Care Professional brand.
An extra attraction at the stand offers a close look at key elements of a functioning circular economy – and plenty of time for questions and discussions. “Our goal is to prepare companies as best we can for their transition to a true circular economy,” says Ulbricht. “Sustainability is not an obstacle to, but rather a driver of innovation. It can be uncomplicated, effective and inspiring. We look forward to talking with our customers about how we can shape a sustainable future in professional cleaning.”
Last year, Tana-Chemie once again demonstrated how successful holistic sustainable management can be — with transparent circular economy practices, a world record, prestigious awards, and groundbreaking innovations.
Even greater transparency with the Green Care Performance Calculator
In addition to savings in CO2, plastic, and crude oil, the Green Care Performance Calculator provides two new values for greater transparency and sustainability: the recycled content of the hollow body and the total packaging are now included in the certificate. Green Care Professional customers can calculate and certify their sustainable impact on the future of our planet. By purchasing Green Care brand products, significant amounts of resources were saved again in Germany and Switzerland in 2025:
– CO2: 1.624.431 kg
– Plastic: 293.903 kg
– Crude oil: 517.335 kg
„Resource savings drive us and our customers forward every day. We are delighted not only about the renewed increase in savings, but also about the steadily growing commitment of our customers to cleaning more sustainably with Green Care Professional,” says Bianca Nerowski, Head of Product Management at Tana-Chemie.
A real milestone: 1 billion recycled bottles
Together with its parent company Werner & Mertz, Tana-Chemie is also celebrating the world record. One billion rPET bottles made from 100% post-consumer recycled material have been brought to market since the start of its recycled material initiative! A record that shows what the circular economy can achieve!
EcoVadis Platinum medal renewed for Tana-Chemie
“We see the Platinum medal, which we have received since 2021 and have been able to renew repeatedly, as recognition of our commitment to holistic sustainability. This means we remain one of the world’s most sustainable companies, as only the top 1% of all companies are honored with the Platinum medal,” says Bianca Nerowski. As a sustainability pioneer and socially responsible company, holistic sustainability has been an integral part of the corporate culture of the brand with the frog in its logo for years.
Switch, the innovative dosing and refill system, has been awarded the Green Packaging Star Award 2025. The system represents a comprehensive and revolutionary solution for the entire professional cleaning industry. The unique combination of a bottle with an integrated dosing cap and the corresponding refill bag effectively contributes to the circular economy and sets new standards in terms of 100% recyclability and waste minimization.
