THE SCIENCE
AUSTRALIAN BOTANICALS TO KILL 99.9% OF GERMS NATURALLY
WASH WILD use Australian flora to create highly potent antibacterial cleaning and care products - within truly natural formulations. WASH WILD is nature’s very own disinfectant - each bottle is crafted with the W4C® proprietary formulation, along with natural ingredients to create powerful natural products - fragranced with the Australian wilderness. All made in Australia and packaged in post-consumer PET to ensure the range is not just natural, it’s also sustainable.
POWERFUL AUSTRALIAN INGREDIENTS
Harnessing the power of natural ingredients, every bottle of WASH WILD comes from plants - there are no synthetic fragrance or harsh chemicals and there are no labelling loopholes or greenwashing, just formulations that won’t cost your health or the earth.
WHAT IS W4C®?
CSIRO, Australia’s National Science Agency worked with WASH WILD to develop W4C®, a unique blend of native Australian oils effective against a range of bacteria and fungi. The innovation was made possible by CSIRO Kick-Start.

The W4C® blend of Australian native oils is highly effective in killing germs and bacteria. It is included in every bottle of WASH WILD in concentrations proven to kill germs such as E-coli, staphylococcus, moulds and salmonella naturally.

On their own, many Australian native oils - such as eucalyptus or tea tree - are highly antimicrobial - but each has different strengths against different pathogens. Finding the most powerful combination has resulted in the W4C® proprietary formulation blend which is potent across a range of different household microbes - killing 99.9% of germs with just a very small concentration in solution.

W4C® is 100% derived from nature.
KEY RESEARCH FINDINGS
- Surfactant (soap) alone is not effective in killing germs and moulds.
- Australian native oils are very effective at killing bacteria and mould even in small concentrations.
- A blend of Australian native oils is more effective against most pathogens than pure oils on their own such as eucalyptus or tea tree.
- W4C® is the scientifically developed blend which is highly potent against a range of household microbes (such as E-coli and staph).
