Yes. The home kits include the empty 750ml spray bottle and the concentrated refill. You buy the container once, then you only use the refills.

No. Tap water is enough. There is no need to use filtered or purified water.

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 (around 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 carried out: 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 associations for nickel-sensitive people 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

With the R5 refill system you eliminate the repeated purchase of single-use bottles, reusing the same container again and again
