How to Make Breastmilk Soap: A Complete Guide

Breastfeeding is one of the best gifts mothers can give to their newborn babies. It not only gives them the necessary nutrients but also helps in bonding. Breastmilk is considered to be natural and nutritious, but did you know that it can also be used to make soap? Breastmilk soap is an amazing product that has benefits like moisturizing, soothing skin irritations, and treating skin conditions. In this article, we’ll guide you through the steps on how to make breastmilk soap.

Steps on How to Make Breastmilk Soap

Step 1: Gather Materials

The first step in making breastmilk soap is to gather all the necessary materials. You will need breastmilk, lye, essential oils, and oils like coconut oil, olive oil, and palm oil. These materials are readily available in any soap-making store.

Step 2: Prepare the Breastmilk

The next step is to prepare the breastmilk you will use for the soap. You can use fresh breastmilk or thawed milk from the freezer. It’s best to pour the breastmilk into an ice cube tray and freeze it overnight. This way, it’s easier to measure and mix with the lye later on.

Step 3: Weigh the Ingredients

Weighing the ingredients correctly is essential in making soap. To do this, you need to use a digital scale that measures to the nearest gram. You’ll need to measure the lye, oils, and breastmilk.

Step 4: Mix the Lye with Breastmilk

This step is probably the most critical part of making breastmilk soap. You need to handle the lye with care as it can cause harm when not handled properly. Mix the measured lye with the frozen breastmilk slowly and carefully, stirring continuously until the lye is dissolved.

Step 5: Melt the Oils

The next step is to melt the oils in a pot on low heat. You need to make sure that the oils are hot enough to mix well with the lye but not too hot that it destroys the essential oils.

Step 6: Combine the Lye and Oils

Once the lye and oils are ready, mix them together slowly and carefully. You need to stir continuously until they blend well.

Step 7: Add Essential Oils

After the lye and oils are well combined, it’s time to add essential oils. You can use oils like lavender, tea tree, peppermint, or citrus oil. Choose the oil that you like, but make sure it’s safe for babies.

Step 8: Pour the Mixture into Soap Molds

The mixture is now ready to pour into soap molds. You can use silicone soap molds that come in various shapes and sizes. Pour the mixture carefully into the molds, making sure to fill them up to the top.

Step 9: Let the Soap Set

Allow the soap to rest and set for at least 24 hours. It’s best to cover the soap molds with a towel or blanket to help retain heat and facilitate the setting process.

Step 10: Remove the Soap from the Molds

After 24 hours, the soap is ready to be removed from the molds. You can pop the soap out of the molds or gently turn the molds upside down and tap them until the soap releases.

Step 11: Cut the Soap

Once you’ve removed the soap from the molds, you can cut them into your desired shape and size. You can use a knife or a soap cutter to achieve your desired shape.

Step 12: Cure the Soap

The final step is to let the soap cure for at least four weeks. This process helps evaporate excess water from the soap and makes it harder, lather better, and last longer.

Explanation on How to Make Breastmilk Soap

Breastmilk soap is a natural and nourishing alternative to store-bought soaps. It contains vitamins, minerals, and antibacterial properties that make it perfect for babies and people with sensitive skin.

Making breastmilk soap is a fairly straightforward process that involves mixing lye and oils with thawed or fresh breastmilk. The lye causes a chemical reaction with the oils, creating soap molecules through a process called saponification.

It’s important to take precautions when working with lye as it can cause skin burns and respiratory problems. Wear gloves, eye protection, and a mask when handling lye.

Once the lye and oils are mixed, you can add essential oils to the mixture for a fragrant and therapeutic scent. Pour the mixture into soap molds and wait for 24 hours before removing the soap from the molds.

The final step is to let the soap cure for four weeks to evaporate excess water and harden the soap. Once cured, the soap is ready for use.
