Choose eco-certified detergents

Selecting an Ecocert-certified detergent is a key step in reducing environmental impact. These detergents meet strict standards for non-toxicity and biodegradability, ensuring that harmful residues do not end up in waterways after washing. A French-made baking soda-based detergent, for example, contains only four natural ingredients and is effective on tough stains.

Consider health and allergens

For those with sensitive skin or allergies, choosing a fragrance-free and preservative-free detergent is essential. Some common preservatives, like isothiazolinones, can cause skin irritation and are often found in liquid detergents. These ingredients are usually marked on the label with symbols such as "MIT," "CMIT," or "BIT."

Make your own detergent

Creating your own detergent at home can reduce packaging waste. A simple method involves dissolving Marseille soap flakes in hot water, adding soda crystals, and letting the mixture rest before transferring it to a reusable bottle. However, homemade detergents may not always be more eco-friendly than certified industrial alternatives, depending on the ingredients and effectiveness.

Try natural alternatives like washing nuts

Washing nuts, derived from the Sapindus mukorossi tree in the Himalayas, offer a natural cleaning alternative. They release saponin, a natural surfactant, when used in the washing machine. However, they are less effective on heavily soiled or greasy laundry. They are also sourced from Nepal and may not be fully sustainable due to their origin and water impact.

Use the eco mode on your washing machine

Modern washing machines have an "eco" mode that uses less water and energy, even though it takes longer. This mode reduces electricity consumption by heating water less, which is the most energy-intensive part of the wash cycle. The ADEME, France’s ecological transition agency, confirms that this setting helps save both water and energy.

Properly dose detergent and avoid unnecessary washes

Using the right amount of detergent is crucial for both environmental and economic reasons. Overdosing does not improve cleaning and can lead to more frequent washes. It is also wise to wait until the washing machine is full and to ask whether a garment is actually dirty enough to be washed, reducing overall water and energy use.
