Making Mother's Milk Cold Process Soap

Erin BaldwinIn a blink of an eye, my sweet baby girl grew into a bouncing, giggling toddler. Recently, when it came time to clean out the freezer, I struggled to figure out what to do with several storage bags full of breast milk since my little one doesn't require expressed milk anymore. Throwing it out was not an option. As someone who struggled with breastfeeding starting out, every drop was like liquid gold. That’s when I stumbled across the idea of making mother’s milk soap.

When making cold process soap you can use almost any type of milk. I selected my favorite recipe from Soaping Essentials and substituted in the breast milk to replace the water ounce for ounce. In about 90 minutes I had five pounds of rich, creamy soap gently scented with DoTerra’s Serenity calming blend of essential oils.

My experience making breast milk cold process soap was extremely positive and it was great to find a way to use the excess expressed milk — especially one that can continue to benefit my little one. One recommendation I would make for those wanting to make their own batch of mother’s milk soap is to keep this batch for your family only as it may be possible to pass along any impurities, etc., that might be in milk.

How to Make Breast Milk Soap

Step 1: I always recommend that you double-check your recipe and run it through a lye calculator to make sure everything is correct. You can find lye calculators online; I use the one from

Step 2: In order to keep the sugars in the milk from scorching, it needs to be very cold or even frozen before adding the lye. One trick is to measure out the amount of milk that you need ahead of time and then pop it into the freezer the night before you plan to make soap.

Cindystroing you can quite literally swap out the water in any cold process soap with breast milk. If you have a recipe that suits the individual mom or baby then just substitute the water for her milk in the recipe. I just made 2 batches of breast milk soap and you should know that it comes to trace very fast even when the milk is frozen, which to prevent scorching it absolutely should be. My 2 batches were completely different recipes, one a face soap which was maily olive oil, and the second a general body bar. Both came to trace fast. Less than a minute. Be ready to pour.
