Soap Nuts: The Benefits and Uses of One Small Berry

Learn how to use all-natural soap nuts for natural eco-cleaning, by SustainableBabySteps.com

New, Unused Soap Nut Berries

Soap nuts are probably the most sustainable cleaning product on the market.

What are they? They are an all-natural, plant-based product (just a nut from a tree!), easy to grow organic and require very little processing or packaging.

They are naturally hypoallergenic, odorless and do no damage to surfaces or fabrics. And there are countless ideas on how to use them, making them sustainable and versatile.

The soap nut comes from the Soapnut Tree (Sapindus mukorossi). The trees produce the small black berry, approximately one inch (2-2.5 cm) in diameter, that are deseeded and the shell is dried prior to use.

The shells used for detergent contain something called saponin, which works as a natural surfactant. Surfactants reduce the surface tension of the water, essentially making it wetter and easier to penetrate into soiled fabrics. This combined with the agitation of your machine or handwashing removes the dirt or particles, then keeps them away from your clothing until rinsing occurs.

Most commercial detergents contain chemical surfactants, some of which (such as 1,2-Dioxane) have been shown to be carcinogenic and volatile. But soap nuts are all-natural and have been used for centuries around the world.

How To Use Soap Nuts

Learning how to use soap nuts is easy...and fun! It just takes a little creativity to see how many things this little berry can do in your home.

Making Liquid Soap Nut Detergent

Liquid soap nut recipes are easy to follow and the results are versatile.

saving liquid soap nuts Storing Liquid Soap Berry Solution

Boil 2 berries for every one cup of water for 30 minutes. You may want to crush or mash the berries before or during boiling to release as much of the saponins as possible. Allow the water to cool, then strain the solution through a muslin cloth, add essential oils if you prefer and store in a recycled jar in the fridge to prevent spoiling. Use the leftover soap nuts and the muslin cloth in the washer together for one load of laundry.

The many uses of this liquid soap are below.

Laundry Detergent

Washing laundry is the most common use. A small cloth satchel with a few berries inside is all that is needed to replace both your regular laundry detergent and your fabric softener.

The number of berries to use depends on the temperature of hardness of your water. For soft, hot water use 1-2 berries; they can usually be used a second time. For cold, hard water use up to 8 berries at least 6 or more times. To check to see if your berries are done, squeeze the shell: you should see a slight sudsy liquid release if they are still good. If you prefer to use the liquid detergent, add 1-3 ounces per load.

Dishwashing

Put 2-5 berries in the cutlery basket of your dishwasher and run as usual. Be sure to add white vinegar as a natural rinse aid.

If you're handwashing, you can make a liquid detergent (above) or add one to the hot water in the sink.

All Purpose Cleaner

Using the liquid detergent recipe above, add 1-2 ounces to your 16 ounce spray bottle. You can add white vinegar or essential oils if you prefer.

The solution can be used on cabinets and cupboards, walls and doors, floors, stainless steel and other metal, wood, tables, shoes, granite and marble, plastic, around pets and kids, sinks, toilets, showers and tubs, and electronics (never spray directly on electronics though; always spray a rag and wipe down gently).

Glass Cleaner

Add two tablespoons of white vinegar and two tablespoons of liquid detergent to a 16 oz spray bottle of water. Add several drops of essential oils if you'd like. Shake well and use as normal.

Shampoo

Yes, it's true! This versatile little berry is great for washing hair. It's even used in Ayurvedic medicine to prevent hair loss; I'm not going to making any speculations or promises there, though!

Mix 1/2 to 1 ounce of liquid soap nut in approximately 12 ounces of water (I recycle an old jar for this one), add your favorite aromatherapy if you'd like and pour over your scalp. Scrub and rinse as usual. You can also add one teaspoon of baking soda to the solution for added strength. And try softening your hair with apple cider vinegar: dilute one ounce with 10-12 ounces of water to rinse your hair after washing.

Body and Face Wash

Just like shampoo, the berries can be used as a liquid body wash or face wash. Add a little to your wash cloth and scrub away!

Insect and Mosquito Repellant

Green Your Clean

It's rumored to repel mosquitoes by applying the liquid to the body (possibly with this natural mosquito repellant) and allowing it to dry. It's safe for babies and kids but there isn't much discussion on it's effectivity. Give it a try and let me know what you think!

Likewise you may be able to use the crushed or used shells around your garden to repel some insects and pests.

Pets

Use the liquid detergent to shampoo pets, wash pet beds or bedding, clean toys and possibly even repel pests by spraying their coat.

Jewelry

Soak your jewelry in undiluted liquid solution, and then scrub clean with an old toothbrush.

Wash Your Car

Use up to a dozen soap nuts and allow them to soak in a gallon or more of hot water for 30 minutes or fill the bucket with pressured water from your hose to release the saponin from the berries. Use that water to wash your car, wheels and even your dashboard, steering wheel and windows. Because it's biodegradable, the wash water can be reused on trees or plants.
