About the Ingredients

The ingredients you need to make your own homemade laundry detergent are quite simple and you should be able to find most if not all of them at your local grocery store. The ingredients you need are:

  • Washing Soda
  • Borax
  • Bar Soap
  • Baking Soda
  • Essential Oils of your choice

Washing Soda

The chemical name for washing soda is sodium carbonate. Washing soda should not be confused with baking soda – the recipe calls for both ingredients. Washing soda is also known as soda crystals or soda ash. You can find washing soda at your local grocery store or you can buy it online at stores like The washing soda acts as a water softener and helps to remove dirt from clothing. It also helps to remove odors. It looks like a fine white powder. The Arm and Hammer brand is one of the most popular brands.


The chemical name for Borax is sodium borate. This is also a soft white crystalline powder and you can also find this ingredient at your local grocery store or online. Borax is a common household ingredient found in most cleaning products. Working with borax may cause skin irritation so if you have a sensitive skin then it’s best to use gloves when working directly with the borax. Borax acts as a deodorizer and cleaner within the detergent.

Bar Soap

Bar soap includes your own homemade version of soap or soap like Fels Naptha, Ivory or Dr. Bonner’s. You are going to be grating the soap so it needs to be a well set bar of soap if you are using your own homemade bar soap.

Baking Soda

The chemical name for baking soda is sodium bicarbonate. The baking soda is not strictly necessary for this recipe. It just makes clothes smell fresher.

Your Choice of Essential Oils

If you would like to add a specific scent to your detergent, then essential oils are a great way to add the scent of your choice. Lavender oils makes a great smelling detergent and citrus oil can also make clothes smell great.

Powdered Laundry Detergent Recipe

The recipe uses parts so it’s easy to make irrespective of the container you are using for the recipe. I normally use a cup but you can choose any container you want to for your soap.


  • 1 Part Bar Soap
  • 2 Parts Washing Soda
  • ¼ Part (A few teaspoons) Baking soda
  • Essential Oils


  1. Place the bar soap in your food processor or grate the soap with a fine grater. Cut the soap into smaller pieces first if you are using your food processor. Pulse the soap until very small or fine grain is achieved.
  2. In a large container, add one part bar soap to two parts of washing soda.
  3. Add a one quarter part baking soda. If you are using cups then add about 4 teaspoons of baking soda.
  4. Add the essential oils you want. Add a few drops at a time. You can always add more but can’t take it out so start slowly since essential oils are really strong.
  5. Use a spoon to mix – or if you’re lazy like I me, add the lid to the container and shake vigorously to make sure everything is mixed well.

Use about a ¼ cup of the powder per load of laundry.

The Benefits of Making Your Own Homemade Laundry Soap

As mentioned above, one of the benefits of making your detergent is that you know what ingredients are in your detergent to begin with. There are no added chemicals or petroleum products to be afraid of if you make your own soaps and for sensitive skin types, this may be incentive enough.

Another big advantage of making your own detergent is that you can make a batch as you run out. With extra ingredients stored in the cupboard you can make another batch without having to stop your laundry to run to the store.

Finally, it costs a lot less to make your own homemade laundry detergent. Depending on the costs of your ingredients, a load of laundry can cost less than twenty cents a load.
