Tri Nature exists for the land, oceans and waterways, which we strive to protect, and the manufacturing industry, which we strive to transform.

The first Australian chemical company to manufacture phosphate and nitrate-free products, Tri Nature also shunned zeolites, enzymes and common phosphate replacements in favour of natural, renewable plant and vegetable based ingredients. 

By reducing the environmental impact and resource waste attributable to the use of household cleaning and personal care products today, we know that Australia and the world can live in a greener tomorrow.

There are many reasons why thousands choose Tri Nature as their safer cleaning alternative… 

  • No phosphates, nitrates, caustic, chlorine, harsh acids, alkalies or parabens

  • No petrochemicals, fillers or extenders

  • Readily biodegradable, highly active concentrates

  • Effective and economical performance – excellent cleaning results

  • Gentle on sensitive skins and noses

  • Suitable for use in septic tanks and waste water management applications

  • Low sudsing detergent formulae

  • 100% Australian owned

  • All products are manufactured in NSW using primarily Australian packaging that is suitable for recycling

  • Products contain in excess of 85% Australian sourced raw materials

  • Products are guaranteed to give satisfaction when used as directed

  • No animal products used, no animal testing undertaken or supported

…HOWEVER one of the most important reasons why Tri Nature products are a responsible choice lies in the increased need for the reuse of grey water in the household and garden, brought about by drought and water restrictions

What is “grey water”?

Water generated in the shower, bath, hand-basin, and laundry. It contains solids, greases and dissolved salts, foreign particles such as soil, sand, bone, soap and the minerals in the original water.

Wastewater directly from the bath or washing machine should not be directed through diversion devices without at least filtration. 

Are there any restrictions applicable to grey water use?
There are different rules for not only different states but also in different local government areas. If you want to collect, store and treat your grey water, you will require approval from your local Council.


What are the most important considerations for reuse in irrigation of gardens and lawns?

  • The quality of the grey water (moderate pH; low salinity and sodicity; low phosphorous)

  • The plants you will irrigate with grey water

  • The soil type in your garden

  • The soil horizons (the different layers of soil as you dig deeper)

  • The soil chemistry and soil microbiology

  • How often you irrigate the same area

“… using cleaning products that are specifically manufactured for grey water gardens. We highly recommend  Tri Nature (Alpha Plus) Liquid Organic Concentrate. This product has been specifically produced for use in the garden.

Tri Nature also produces a washing conditioner called Angelica, which has very low sodium content and is suitable for use in the garden.” Peter Shepherd, Waterwise Systems

How do I know what products are suitable for use in my garden?

Products that are low in sodium (less than 10gm per wash), contain little or no phosphorous (less than 1gm per wash), have a moderate pH (no higher than 8 for liquids and no higher than 10.5 for powders) and are of low salinity are easiest to work with.
