Soy Milk Soap 10

 in Cold Process Soap / Soap by

Finished Soap

Soy milk is a major part of Chinese life. Unlike life in Utah, soy milk can be found EVERYWHERE! I’m not even talking about shelf stable cartons of sweetened soy milk found at the grocery store. Here in China, soy milk isn’t worth considering unless it is fresh, hot and steaming. Want sweeter soy milk? You can add your desired amount of sugar right from a big bowl of sugar.

Weighing Oils

One of my favorite soaps while I’ve been in China has been my batch of unscented soy milk soap that I made before coming to China. I decided to remake the batch of soy milk soap with one change. This time I decided to add a little bit of Elements of Bamboo Fragrance as it is a nice scent that appreciated by my friends and family who come to visit. I decided to use a light usage rate so it wouldn’t overwhelm or offend any of the noses of my visitors.

Time spent:

Weighing time: 8 minutes
Adding lye to water: 15 seconds, followed by 60 seconds of stirring
Heating of oils time: 3 minutes
Pouring lye solution into the fat mixture: 10 seconds
Using immersion blender to mix soap solution: 90 seconds
Adding milk to the batch: 20 seconds
Using immersion blender to completely mix milk into soap: 40 seconds
Pour into molds: 60 seconds
Allow soap to rest: 24 hours

Adding Lye Solution

1) Calculate the amount of lye and liquid needed for the oils you plan to use.

2) Measure all of the oils and set aside to heat gently.

3) Measure the lye and set aside.

Mixing Soap

4) Measure HALF of the needed liquid as water and set aside. Measure HALF of the needed liquid as soy milk and set aside. Milk should be room temperature, not frozen or hot.

Measuring Soy Milk

5) Add ALL of the lye to the water. Stir well. No crystals should remain on the bottom of your mixing vessel. When the temperature of this lye solution is within 110° F to 130° F, (cooler in the summer and warmer in the winter, cooler for large batches and warmer for small batches), add it to the oil mixture. Blend with an immersion blender until you estimate you are halfway through the mixing process. This will happen with most oils in about 1 minute. The mixture should NOT be thick or viscous. The mixture should be very fluid, like water.

Mixed Soap

6) Now steadily pour the milk into the batch. Use the immersion blender to finish the blending so there is no chance of separation.

7) Add fragrance. Pour into prepared SHALLOW molds (1 inch deep or so). Milk soaps can get very hot and shallow molds help the excess heat dump into the air. This will prevent the milk sugars from interrupting the saponification reaction.

Director of Happiness. I'm a thirty-something soap snob. I've grown up with handmade soaps, and I love them! I really like making lotions, soaps, and perfumes. I adore mixing scents to come up with something new. My favorite scent is either Wicked or Cotton Candy. I tend to hoard fragrances, I even have an Earl Grey Tea from the MMS catalog. I won't tell you how old it is, but it sure is good!

    I’ve been trying to figure out how to make my log molds work for milk soaps, but the soap inevitably cracks, which makes me do a crazy unhappy dance. Why I didn’t think of using a shallow mold… d’oh! Thank you, Taylor! I needed the obvious pointed out! 🙂

    I am excited to try this 🙂 How do you think it compares to goat milk soap for moisturizing feelings, gentility, etc.??

    Hi Taylor! Just curious — how do you think the soy milk compares to other milks for gentility, moisturizing, etc.??? We tried our first batch of goat soap and I love how gentle and soft it feels. Curious if that is fairly consistent with all milks or if a plant derived milk like almond or soy would be much lighter feeling?

    Excited to try something new 🙂

    Andrea,
    I think all milk soaps are fantastic on skin. Each milk type adds a slightly different feel, but all milk soaps do give that extra oomph to the pampering and moisturizing feel. I find that plant based milks tend to be lighter in color, but I can’t remember any other difference since it has been a while since I compared an animal milk soap to a plant milk soap.

    I have been using coconut milk in my soaps, and let me tell you, there has never been such a luxurious, silky lather from any of my other soaps!

    Even my hubby, who could care less what he uses for his personal care, loved it!

    Of course, (when I remember) I add sugar to the liquid before adding the lye, and that is supposed to boost the lather too, but coconut oil itself give a nice lather too.

    My milk soaps have never cracked, I freeze the milk and make it slushy before slowly adding the lye…I don’t use water.

      Aren’t milk soaps fantastic?

      I know that many people make milk soaps and add the sodium hydroxide to the frozen milk. I had one batch made this way fail by stalling and for me that was one too many batches. I like to have my soapmaking be stress-free and fun, so the half & half method is my favorite because it is a fail proof method if followed correctly (plus it is easy!). It could be that my work style lives by the phrase of ADOS (attention deficit …. oh shiny!) and I need to keep my processes simple to avoid being interrupted and forgetting items.

      Either way, let’s make soap and have fun!

    Thanks Andee! We love the goat’s milk soap at our house and we have goats so we have a constant supply of fresh milk to play with. The plant derived soaps are beautiful. I will have to make some up and see how my family thinks of them in comparision 🙂 Can’t wait to try it!!!!

    THANK YOU!!!!

    So excited that I received a sample of this with my order, thank you! It lathers nice, feels smooth and smells so clean. Think I may have to break out some of my old soap molds now.
