Gentle Baby Soap Bar Recipe

This homemade baby soap bar is gentle and safe for sensitive baby skin. Made with coconut oil, mango butter, and jojoba oil, this cold-process baby soap nourishes and moisturizes the baby’s skin.

Making soap is actually quite simple and can be made for a relatively low cost. My soap-making days started with melt and pour bases solely due to the fact I was very nervous about the lye. But as with most things, after I made it once, I realized it was much easier than I thought and could be done safely.

This baby soap recipe is perfect for baby’s skin; it is gentle, cleansing and leaves the skin soft and smooth. This soap is made with all-natural ingredients and scented with pure lavender essential oil.

How to Make the Best Homemade Baby Soap Bar?

In order to make cold-process soap bars, you will need lye, a liquid and either a fat or oil. The oil, when mixed with the lye, is what allows for the saponification process making the lye safe. Choosing different oils or fats, for example, allows you to make different styles of soap, such as a moisturizing soap bar for dry skin, while others will make the perfect bar for oily skin.

For this baby soap recipe, I am choosing gentle and moisturizing ingredients that are perfect for sensitive skin.

Natural Baby Soap Recipe

I used a soap calculator to get these exact measurements. If you want to change up the recipe at all, you will need to get new measurements. Having the right proportions is a crucial step in soap making. 

Safety Note: When working with lye, be sure to work in a well-ventilated area and wear safety goggles and rubber gloves. If lye gets on the skin or in the eyes, it can be very harmful.

How to Make Soap for Kids

1. Using a digital scale, measure out your water and pour it into a heat-resistant glass or thick heat-resistant plastic pitcher. 
2. Measure out the lye and add it to the water. Stir the lye into the water slowly until it dissolves. Note, the chemical reaction will cause it to heat up quickly.
3. Using the digital scale, measure out the coconut oil, mango butter, and jojoba oil. Pour into a medium-size saucepan and melt over medium heat. 
4. Once the oils and butter are melted, remove it from the heat. 
5. When the oil cools to 100°F, slowly add the lye and water mixture to the oil, mix with an immersion blender. This will take a couple of minutes. You will know it is the right consistency when the soap from the blender drips and pools up on top of the soap in the saucepan. This is known as the trace. 
6. Add in the lavender essential oil and mix in with the immersion blender.
7. Pour the soap into a soap mold. If using silicone soap molds, no prep is required. Other molds may require parchment paper. 
8. Allow the soap to harden in the molds for a minimum of 24 hours or up to 3 days. 
9. Remove the soap from the molds and allow to cure for an additional 3-4 weeks before using.

How to Use Natural Baby Soap

Use the homemade baby soap bar like normal, staying clear of your child’s eyes. This soap bar will work great for both the hair and body. Allow the soap to soak in for a couple of minutes before rinsing off with warm water.
