Our refills are formulated with 100% plant-based surfactants, produced by certified European suppliers. One of the surfactants is RSPO Mass Balance certified (Roundtable on Sustainable Palm Oil), ensuring a controlled supply chain. The raw material supplier is certified according to the RSPO Supply Chain Certification standard (ICEA certificate no. 19/2024). The other surfactant is produced in France using an innovative process that makes use of waste from the cereal industry (wheat bran and straw). Its raw materials are approved according to the COSMOS v4 standard by the Ecocert Greenlife certification body (certificate no. 115511). The ingredient contains no petrochemical components or non-natural ingredients.

Nickel is a metal that can be present in trace amounts in many commonly used products, including cosmetics, detergents, and food. It is one of the most common causes of allergic contact dermatitis (approximately 10-15% of the European population is sensitive to nickel). To meet the needs of nickel-sensitive people, we subject some of our products to a specific analytical test to determine the nickel content. How the test was conducted: Method: ICP-MS (Inductively Coupled Plasma Mass Spectrometry) Reference standard: EPA 6020B:2014 Laboratory: Innovhub SSI (Milan) — independent external laboratory Limit of quantification (LOQ): 0.1 mg/kg What does the result "< 0.1 mg/kg" mean (equal to <0.1 ppm)? The reported value indicates that any nickel present in the product is below the instrument's limit of quantification (0.1 mg/kg, equal to 0.1 parts per million). ICP-MS is the most sensitive analytical technique available for determining trace metals. Technical note: there is currently no specific legal limit for nickel in detergents (EC Reg. 648/2004) or cosmetics (EC Reg. 1223/2009, Annex III) in Europe, but dermatological literature and nickel-sensitivity associations indicate guideline thresholds between 1 and 5 mg/kg for safe products. The value found in our tested products is 10 to 50 times lower than these thresholds. The full test report is available upon request

The refills are formulated and produced in Italy along a supply chain of partners selected according to our ISO-certified quality system (ISO 9001 and ISO 14001)

No. You can use any 750ml spray bottle you already have at home, provided it is clean and rinsed, following the proportions indicated on the sachet.

Each refill measures 5x13 cm and is less than 1 cm thick. The box containing two refills measures 5.5x13.2x3.5 cm. This makes it easy to keep a supply on hand and never run out: it takes up much less space than classic plastic bottles

The empty refill should be disposed of with paper recycling.

Yes, our refill packaging is made of FSC-certified paper and is recyclable with paper. We explain in detail how it is made, because transparency about materials is a core value for us. The outer box is made of 400 g/m² kraft-back cardboard, FSC Mix certified (license number CQ-COC-000075). It is 100% paper and should be disposed of with paper recycling. The refill sachet: it is technically the most delicate component, because it must contain a liquid product without leaking. It consists of: FSC-certified thermoformable paper (license CQ-COC-000208), PE/EVOH/PE barrier film: solvent-free adhesive. The thin, transparent internal barrier film is essential: without it, the paper would absorb the liquid and the sachet would not hold. We chose the solution that minimized this layer, keeping 80% of the overall weight in paper. The sachet is recyclable with paper, as certified by Aticelca Level C — the Italian reference body for recyclability in the paper collection stream. How to dispose of the packaging correctly Box → paper recycling Refill sachet → paper recycling Always follow your local municipal waste collection guidelines, as they may vary slightly.

Yes. R5 Floor is also suitable for use with robots and floor cleaners. Prepare the product as usual: pour the contents of one refill into a 750 ml bottle and add water. For use with the robot: follow your robot's instructions; if detergents are permitted, use 6 ml of product for every liter of water
