Breast milk is one of the healthiest substances. This precious golden liquid is packed with nutrients to nourish a developing brain and help babies double in size in just a few months.

So, many nursing moms have used leftover breast milk to create soaps, which are seen as a natural alternative to treating eczema in babies and even adults.

Then, how to make breast milk soap? Let’s read on to find out right now!

Benefits of Breast Milk Soap

Breast milk is a gift from God. Many of us even consider it liquid gold. Besides the benefits for the baby’s physical development, it is also beneficial for the baby’s sensitive skin by treating some skin diseases.

We all know that breast milk has powerful immune properties, but that’s not all.

There are many more beneficial ingredients found in this precious golden liquid, such as amino acids, proteins, enzymes, antibodies, probiotics, fatty acids, minerals, vitamins, and more. The list of nutrients goes on, and there are still things undiscovered.

This liquid is very gentle and nourishing to the skin, making it the perfect choice for treating eczema, conjunctivitis, and diaper dermatitis. In addition, it has almost no adverse side effects. So you can avoid unnecessary additives that hurt your baby’s sensitive skin.

Also, making soaps from breast milk allows you to customize it to your needs. In other words, it is possible to tailor what is in your soaps. It is excellent for those who have family members with skin conditions, as you can pick the ingredients that are best suited for your needs and health.

You will know what is going into your soaps. As a result, you can pick the most eco-friendly choices.

Cold Process Soap Vs. Melt and Pour Soap

When comparing these two soap-making recipes together, each has pros and cons. We will point out some things you consider when deciding which one is for you.

Adding Ingredients

The Cold Process will provide you with the most freedom when talking about adding ingredients,

You can add your milk to the Melt and Pour soap or additional additives that add so much liquid. However, adding milk or oils will affect the hardness of the final soap bars.

It does not mean you cannot add ingredients to the Melt and Pour soap. It is possible to add minimal amounts of colors, essential oils, and oils. But it will lock into specific amounts without using milk and honey.

Handling Lye

Generally, the handling of lye and toilet bowl cleaners is the same. Therefore, it is unnecessary to be scared of it if you do not touch it. Also, remember that there is no left lye after the soap-making process. So it can be considered a safe pick for making natural soap.

Yet, if your goal is to avoid lye altogether, you should choose the Melt and Pour soap. It contains lye that has been handled for you.

It is possible to melt it and put your color, herbs, and scent. After that, pour it into a lovely mold to gain designed soaps.

Friendly For Kid

In our opinion, Melt and Pour soaps are a perfect pick for your baby.

While Cold Process soaps deal with lye, their Melt and Pour counterpart is a good way for you to “make soap” through melting and pouring into cute molds.

Melt and Pour soaps have a shorter shelf life and are best stored in your fridge. Meanwhile, if you store Cold Process soaps in a place away from moisture and sunlight, they will have a shelf life of at least six months.

We prefer both methods for different reasons, although our favorite pick is Cold Process soap, partly because we like being able to control what goes into our soaps. On the other hand, we also love its texture and feel.

Step 10: If your soaps have been unmolded, put them out onto greaseproof baking paper or parchment paper to store in a well-ventilated place away from direct light for at least six weeks.

This curing period lets any residual liquid evaporate and test your soap’s lather.

1. How Long Does Breast Milk Soap Last?

Breast milk soaps may last long, as your milk changes into lye before setting in your soap mold. As a result, you do not have to worry about your finished soaps going bad four hours out of your refrigerator like regular breast milk.

Most milk-based soaps have a shelf life of about five to ten years.

2. How to Store Breast Milk Soap?

We recommend storing your breastmilk soaps in a small zip-lock bag and storing them in the refrigerator. We recommend storing them in the freezer if you know you’re a long way from using these soaps.

When you use a milk soap bar, you need to make sure it dries completely between uses. The best thing is to put it in a dish of soap that drains well.

Once you notice your soaps turn darker or smelly, it’s time to throw them into the trash.

3. What Can I Put In My Breast Milk Soap?

Honey and oatmeal do not only make a perfect-tasting breakfast, but they also make soaps that will smell as good as it feels.

In addition to essential oils, you can also add olive oil to your breast milk soap. This oil helps create a lot of foam.

Yes. It may help control or prevent acne.

It contains ingredients that gently remove dead skin cells, which help you prevent acne by keeping your pores clear of dirt, excess oil, and sebum.

Furthermore, breastmilk soap is gentle and may help maintain the skin’s moisture. It will help the skin absorb the beneficial vitamins, fatty acids, and minerals without disrupting its natural balance.

Breastmilk soaps to cleanse your skin can treat acne and lower inflammation associated with pimples. Thanks to that,  you will have clear and smooth skin.
