Reduce plastic usage with these single use dish soap bars

Honestly for a lot of years I didn’t give buying a bottle of dish soap a second thought. But lately we’ve been taking a close look at ways we can reduce plastic usage. While we won’t ever be “plastic-free”, we can be more mindful of our purchases and this is a simple step to take

And some added bonuses – you’ll save money too. These bars are inexpensive to make so you’ll save money in the budget. Plus you have complete control over the ingredients, so no harsh ingredients!

The first batch I made was the first cold process soap I had made in almost 20 years! When I made soap before, I struggled with consistent results because I wasn’t using a digital scale or an immersion blender. With those tools on hand, it is SO much easier. You still need to be mindful of the lye. Safety gear like gloves is important.

Check out Brambleberry.com for soap making supplies, it, along with Amazon, is one of our main sources for supplies. Sometimes you can find what you need at local grocery or big box stores as well. We’ll be doing some posts and videos on soap making for beginners, so if you’re a newbie, stay tuned for more help.

Dish Soap Bar Recipe 2.0

While I loved the simplicity of the first dish soap bars I made, I wanted a little more cleaning power so I did some research, looked at about 1,436 recipes, and came up with this one. If you are attempting to change a recipe or create a new one, make sure you use a lye calculator to make sure your numbers are correct. You don’t want to go through the time and effort of soap making to end up with something to caustic to use.

With this dish soap bar recipe, I added citric acid, lime juice, lemon peel powder and increased the citrus essential oils. I increased the castor oil amount slightly to make it a little more sudsy. Now I don’t want to finish using up the bars from the original batch (but I will. Or maybe I’ll rebatch them. We’ll see)

Get a scrub brush and a soap dish, and you’ll be able to say good bye to one source of single use plastic in your home. This recipe makes about 12 bars. Based on my unscientific research, 2-3 bars = one bottle of dish soap.

Dish soap bars

amazing cold process dish soap bar for clean dishes and less plastic use

Ingredients

28.8 oz  coconut oil

3.2oz castor oil

8.5 oz water

5.6 oz lye

2T citric acid

2oz lime juice

2T lemon peel powder

15mL lime essential oil

15mL lemon essential oil

Instructions

Place the water in a heatproof containter. Wearing protective gloves and eyewear, slowly sits the lye into the water until fully dissolved. (always add lye to water, not the other way around). Set aside until the temp drops to 100-110 F (38-43C)

While the lye is cooling, combine the coconut and castor oil. Warm until coconut oil is melted. My soap making container is the pot I melt the oils in, but if you’re using something else, pour it into your soap making bowl and add a thermometer.  You want the oil and the lye solution to be within 10F of each other. 

When the temps are correct, blend in the citric acid, lime juice, lemon peel powder and essential oils to the coconut oil mixture and blend well with immersion blender. 

Now it’s time to add the lye solution. Mix with the immersion blender until you reach a light trace. Because of the high coconut oil content it will set up quickly so don’t let it get to a heavy trace. Pour the soap into the mols of your choice and use a spatula to smooth. Allow the dish soap bars to so set up overnight and then remove from molds.  Allow to cure for at least 3-4 weeks.
