Best Eco-Friendly Dishwasher Detergents in the UK


Switch to an eco-friendly dishwasher detergent and you will drastically reduce your personal impact on the planet. Period.

We all know that dishwasher detergents are full various chemicals that promise to get out dishes clean.

But most of us don’t realise just how harmful these chemicals can be for the environment, especially the marine environment.

Luckily, it’s very easy to find an eco-friendly alternative to these regular brands and, contrary to what many people think, they often work better too.

Keep reading to find out why regular dishwasher detergents are so bad for the environment and learn which are the best eco-friendly dishwasher detergents you can buy in the UK.

Why Are Regular Dishwasher Detergents so Bad for the Environment?

The biggest problem with those regular dishwasher tablets, powders and tabs is that they contain high levels of a chemical called phosphate.

Once you’ve used it to get your dishes clean, it washes straight into the streams, rivers, lakes and oceans of the world.

Algae and phytoplankton in the water will feed on the chemical and will reproduce way beyond normal levels, causing an algal bloom.

This bloom can block out sunlight, cause an oxygen imbalance in the water and ultimately kill marine wildlife.

Certain types of algae such as blue-green algae can be dangerous to humans too and even kill.

However, phosphates aren’t the only problem.

Dishwasher detergents also contain a myriad of harmful chemicals including chlorine, surfactants, synthetic fragrances and colours, antibacterial agents like triclosan, and other similar chemicals which are also toxic to marine life.

Then there’s also the problem of the packaging: most dishwasher detergents come packed in several layers of plastic including the outer packaging and often plastic wrapping around each tablet.


How Can We Find Eco-Friendly Dishwasher Detergents?

We’ve included a pick of our top 5 green alternatives in the list below, so you needn’t worry too much about figuring out the labels.

Having said that, here are a few tips to help guide you when reading those labels.

  1. Choose a phosphate-free or low phosphate detergent. Look for those with less than 1.6% of phosphates.
  2. Buy a concentrated dishwasher detergent whenever possible as it reduces carbon emissions produced during shipping. You dilute concentrated dishwasher detergent with water.
  3. Look for 100% biodegradable or recyclable packaging.
  4. Make sure you read those labels closely. Even if the brand claims to be eco-friendly, there can sometimes be a few surprises
  5. Avoid synthetic fragrances as they often contain phthalates which can disrupt your endocrine system.
  6. Choose organic, palm oil-free detergents that are free from animal testing. Better still if they’re vegan.

***NOTE: Since 2017, the EU have limited the amount of phosphates allowed in household dishwasher detergents. This may be subject to change after Britain’s exit from the EU.***

Right, let’s get onto our favourite eco-friendly detergents.
