What makes a good zero waste laundry detergent?

A good eco-friendly laundry detergent should have a positive environmental and ethical impact.

Plastic Free / Recyclable Waste

Ideally it needs to be plastic free, or 100% recyclable. You could save 40 bottles of plastic each year if you switched from liquid detergent and fabric conditioner to a plastic free option.

Cruelty Free & Vegan

We only rate laundry detergents with ingredients that are not tested or derived from animals, and companies with a clear cruelty free policy. Washing our clothes shouldn't be at the expense of animal welfare.

 Non-toxic

All the detergents below are non-toxic, and free from phosphates, formaldehyde, parabens, triclosan or phthalates. We've also listed whether they contain other ingredients such as fragrance, enzymes, SLS, bleaching agents and more below.

Laundry Detergent FAQs

What's the different between bio or non-bio detergent?

The difference between bio and non-bio washing powers (or detergents) is that bio contains enzymes (to help break down common stains like grass, chocolate, burger grease) whereas non-bio does not contain them. Here's a quick comparison:

Bio Detergents Non-bio Detergents
Enzymes effectively remove stains No enzymes to lend a hand in stain removal
Can wash at lower temperatures or quick cycles May have to wash at higher temperatures for deeper stains
Can sometimes cause irritation for super sensitive skin Suitable for babies and sensitive skin
Can reduce colour over the long-term Maintains colour for longer in clothing

What is SLS?

Sodium Lauryl Sulfate is a common chemical that can be made from coconut oil, palm kernel oil or petroleum used in products from toothpaste to soaps, shampoos and laundry detergents. It works as a surfactant, trapping oil-based dirt with a soapy lather so it can be rinsed away with water. It's low cost to produce and biodegradable, however it can cause irritation for those with sensitive skin due to its oil stripping qualities.

What are optical brighteners?

Optical brighteners or optical brightening agents (OBAs) are chemicals that absorb ultraviolet light and reflect back blue light. Their purpose to help whiten the normal yellowing or greying of clothes and make them appear brighter.  Essentially they do this by adding a coating of microscopic fluorescent particles to your clothes rather than removing the yellowing or stains. Optical brighteners aren't readily biodegradable and may bioaccumulate, so could pose a threat to aquatic life. They can also cause irritation and phototoxic reactions if they rub off onto skin and then skin is exposed to the sun.


Years ago people used to add a small amount of blue dye to fabric to make it appear whiter which was known as 'bluing'. An easy alternative to optical brighteners is to soak clothes in lemon juice and water (the citric acid in lemon works as a bleaching agent) or add a cup of lemon juice to your rinse cycle then hang to dry in the sun. It's also safe to use on coloured clothes.

What are bleaching agents?

In detergents stains are removed by oxidation (bleaching). This can be done in one of 2 ways, oxygen-based bleaching agents or chlorine-based bleaching agents. The differences of these are below:

Oxygen-based Bleaching Agent Chlorine-based Bleaching Agent
Hydrogen-peroxide with sodium or sodium carbonate (washing soda) Sodium hypochlorite most commonly known as chlorine bleach
During a wash the peroxide is consumed and the carbonate remains During a wash it decomposes to form water and sodium chloride (kitchen salt)
Gentler on skin and lungs and less toxic Respiratory and skin irritant and corrosive
Can be used on all sorts of fabrics, colours, wool, silk and more Can weaken and damage fabrics
May not be as powerful as chlorine bleach for removing stains, disinfecting and deodorising Powerful at removing stains, is a disinfectant and deodoriser

Should laundry detergent be palm oil free?

It's a complex issue as boycotting palm altogether could have some drastic unintended consequences. For example, producing an alternative oil like soy, coconut or sunflower would need between 4 and 10 times more land and/or shift the problem to other parts of the world, along with threatening other habitats, communities and livelihoods. I wrote about this topic more on the Best Zero Waste Shampoo & Conditioner shopping guide, or you can take a look at OpenMind's article: Boycotting Palm Oil May Worsen the Situation. We support brands that are considerately sourcing their ingredients and not using palm oil as a direct ingredient itself. However, we advocate the use of ingredients derived from RSPO certified palm oil if this is the best option comparative to other oils.
