marwian product: Xliquid®

Xliquid® is the tradename of our new biocidal active substance.
It is biologically degradable, not carcinogenic and highly effective against bacteria, fungi, enveloped viruses (i.e. Corona-Virus) and algae. Xliquid® also requires low in-use concentrations.

Xliquid® has an amazing substance profile regarding toxicity and environmental fate properties compared to existing guanidine based biocidal active substances.

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.
