Compounds which make some laundry products unsuitable for greywater irrigation

Sodium
Salt (sodium) is a by-product of the manufacture of washing agents and included in many powders as a filler. There is generally less salt in concentrated powders, and even less, if any in liquids. Fabric softeners also contain high levels of sodium.

Phosphorus
Excessive phosphorus in greywater can be toxic to native plants and also cause iron deficiencies.

Choose a washing agent that has low phosphorus.

One useful product found in washing detergents is the surfactant
Most laundry detergents contain surfactants which are wetting agents to help clean your clothes.

These same surfactants will act as wetting agents in most garden soils, negating the need to introduce

wetting agents into your garden.
