Its name means "soap from India", since its fruits for centuries were used as a natural detergent to wash the body, clothes and hair.
All the trees that belong to the genus Sapindus contain in the peel of their fruits a natural substance called "saponin" whose main characteristics are detergents, that is why they are known as "washing nuts".
The saponin, when it comes into contact with water, dissolves and produces a soapy solution that cleanses, generating a light foam with a pleasant smell.
What are the advantages of using these nuts for washing?
It does not pollute
Washing in this way is much less harmful to the environment compared to the foams produced by industrial chemical detergents. In addition, the water used in washing does not contribute any pollutant to the environment, and can be used as irrigation water.
It is cheaper
On the other hand, it is cheaper than the use of conventional detergents. One kilo of walnuts makes 100 washes in the washing machine or 6 months of washing for a family of 3.
If you wash, you don't need fabric softener
In addition, you do not need to use softeners since it gives a natural elasticity to the fabrics. In fact, it is recommended for delicate fabrics. They will be very soft, with a very pleasant smell and the colors will remain intact.
Being neutral, it is recommended for allergy sufferers and with sensitive skin. In addition, when used as a shampoo, it leaves hair smooth, shiny and easy to comb.
How to use these fruits to wash?
To use these fruits, once you collect them and the nuts are dry, peel them separating the shells. Then put 3 of them in a cotton bag and use it with your clothes to wash them. The aroma is very mild, so you can also add a few drops of oil if you want a more intense perfume.
