Can I Use Expired Breast Milk to Make Soap?
The question of whether expired breast milk can be used to make soap is gaining traction among DIY enthusiasts and eco-conscious individuals. The short answer is yes, you can use expired breast milk for soap making, but there are important considerations to keep in mind.
Understanding Expired Breast Milk
Breast milk is often referred to as “liquid gold” due to its rich nutritional content and numerous health benefits. However, when breast milk expires, it is no longer suitable for consumption. Despite this, many people find creative ways to repurpose it, particularly in skincare products like soap and lotion. Expired breast milk retains many of its beneficial properties, such as vitamins and fatty acids, which can be advantageous for skin health.
Soap Making Process
When making soap with expired breast milk, there are two primary methods: hot processing and cold processing. Both methods involve the use of lye, a caustic substance that has a high pH level. This high pH is crucial as it effectively neutralizes any pathogens that may be present in the expired milk, ensuring that the soap remains safe for use.
For those interested in the cold process method, it’s important to note that the soap may take 4 to 6 weeks to cure before it is ready for use. This curing time allows the soap to harden and ensures that the lye has fully reacted with the milk and other ingredients.
Practical Tips for Soap Making
If you’re considering making soap with expired breast milk, here are some practical steps to follow:
1. Preparation: Start by gathering your ingredients, which typically include a soap base (like glycerin), lye, and any additional oils or scents you wish to incorporate.

2. Melting the Soap Base: If you’re using a pre-made soap base, melt it in the microwave or a double boiler. For example, you might microwave 0.5 pounds of the soap base for about 30 seconds, stirring until fully melted.
3. Mixing in the Milk: Once the soap base is melted, mix in the expired breast milk thoroughly. This combination not only adds beneficial properties to the soap but also contributes to its texture.
4. Molding and Curing: Pour the mixture into silicone molds and allow it to set. After the initial setting, remember to let the soap cure for the recommended time before using it.
Safety Considerations
While using expired breast milk for soap making is generally considered safe, it is crucial to ensure that the milk has not been stored improperly or for an excessively long time. Breast milk that has been frozen and then thawed is often a better candidate for soap making than milk that has been left out at room temperature for extended periods.
In conclusion, using expired breast milk to make soap is not only a sustainable practice but also a way to harness the natural benefits of breast milk for skincare. With proper preparation and safety measures, you can create a unique and nourishing product that reflects your commitment to reducing waste and caring for your skin.
