An age-old alternative to chemical laundry detergent, soap nuts are a 100% natural detergent. You’ll have no problem using soap nuts if you have sensitive skin or nut allergies, as they are not actually nuts but berries. The fruit gets the “nut” in its name from the hard shell that forms around it when it dries. If you are interested in making your laundry routine more environmentally friendly, try soap nuts for an all-natural clothes wash.
Soap nuts are the fruit of the Sapindus mukorossi tree. The tree is native to some areas in India and Nepal. Soap nut trees also grow in southern China and Florida. The soap nut tree takes about nine years before it produces fruits. Its fruits appear by July/August and are ready for harvest by November/December. With a harvest period of about six months, it lasts throughout the winter. The tree can live for up to ninety years and can grow to a height of 20-25 meters. The tree grows best in tropical and subtropical regions.
The soap berries have a golden tone when they are newly harvested but turn tan or dark brown when dried. There is a round dark-colored seed inside the berry. Most of the products available commercially are sold without that seed.
The soap berries contain saponin. The saponin is a surfactant, which causes the nuts to produce a soaping effect. The hardened outer layer contains most of the saponin, so it is common to see them being sold separately from the inner seeds.
Soap nuts can get dark and sticky if they are not stored carefully. However, this does not mean they have gone bad; dark and sticky soap nuts may not be pleasant to look at, but they still wash perfectly. Soap nuts absorb moisture quickly, and water leads to saponin release. So it is best to store them in dry, air-tight containers.
Soap nuts work well with high-efficiency washers because of the low suds they produce. They also work well with top-loader washing machines too. It's worth carrying out a patch test on some clothes before going all-in for this natural detergent.
Consider how much harm chemical laundry detergents can cause. They contain ingredients that pollute the environment and endanger our health. They contribute to water pollution, contaminating groundwater, and causing eutrophication of rivers. Some ingredients used in the production of detergent may cause allergic reactions and skin irritation.
