Xliquid®: Our new biocidal active substance
Marwian GmbH developed and manufactures Xliquid® — a polymeric guanidine based biocidal active substance. Xliquid® is highly water soluble and can be used for disinfecting as well as for preservation purposes.
- Xliquid® is not carcinogenic
- Xliquid® is not mutagenic
- Xliquid® is not reprotoxic
- Xliquid® is not a endocrine disruptor
- Xliquid® is not flammable
- Xliquid® is easy to store
better biodegradability
Xliquid® is significantly better biodegraded than traditional polymeric guanidindes*. It shows a factor of 50* better biodegradability * OECD 303A compared to CAR* of substance PHMB 1415 4.7)
High Efficacy
Xliquid® shows high efficacy against the most important pathogens. It is effective against gram positive, gram negative, yeast funghi and enveloped viruses.
Safe Use
Not carcinogenic. Not mutagenic. Not reprotoxic. No endocrine disruptor.
In use concentrations of Xliquid® pose no risk for humans and environment.
Xliquid® offers great efficacy against bacteria, enveloped viruses(i.e. Corona Virus), fungi, yeast and algae. Get your free sample now!
human hygiene/ skin disinfection
Xliquid® is ideal to formulate water-based disinfectants which are skin gentle compared to regular alcohol disinfectants. Xliquid® is not detergent and thus do not remove of the skin lipid layer.
Xliquid® is bactericidal, yeasticidal and is virucidal against enveloped viruses (i.e. Corona Virus).
We conduct EN suspension tests in house within our microbiology lab to formulate and develop new product formulations.
Contact us if you are interested in the development of disinfectant products with Xliquid®. Marwian GmbH accumulated extensive data on efficacy against many pathogen organisms in different quantitative suspension set ups.
Disinfectants not intended for direct application to humans
Xliquid® can be used to formulate surface disinfectants with antibacterial, antifungal and antiviral properties. Alone or in combination with other antimicrobials, detergents, sequestrants.
Contact us if you also want to run tests for your development of products with Xliquid® or if you want more information on efficacy of Xliquid® in quantitative suspension tests.
Xliquid® can also be incorporated into different matrices to produce surfaces with antimicrobial properties.
Incan preservation
Xliquid® can be used for many technical products with very low in use concentrations to preserve end products label free. Xliquid® can also be used with or without other preservatives like isothiazolinones (MIT, BIT etc.) and others. There is a limitation with anionic compartments in the carrier matrix. Possible applications include:
• polymer dispersion • glues (starch and others) • latex • PVOH • pigment dispersions • paper and cardboard

Process water
Xliquid® can be used to preserve process water in industrial settings. Its stable chemical nature and broad efficacy makes it ideal for long lasting and low level in use concentration for closed water cycles. Residues can be easily removed from surfaces.
Due to its high efficacy against algae, gram positive as well as gram negative bacteria Xliquid® be alternated with other biocides.
Xliquid® under the BPR — Legal status:
We filed a dossier for our new active substance for approval to ECHA in 2021.
Currently the evaluation of the submitted dossier is taking place at the evaluating competent authority (eCA) which in our case is the eCA in Austria*.
