Rice bran oil is an excellent addition to cold-process soap recipes. It provides exceptional moisturizing and skin-nourishing properties that make it perfect for crafting a bar that leaves skin feeling soft and supple. In this article, we’ll explore why you should consider using rice bran oil in your next batch of cold-process soap.

Why Use Rice Bran Oil in Cold-Process Soap?

Rice bran oil has many beneficial properties that make it a fantastic addition to cold-process soap recipes. Here are some of the main reasons why you’ll want to try using rice bran oil in your next soap-making project:

  • Excellent moisturizing properties due to fatty acid composition
  • Nourishing for mature and dry skin types
  • High vitamin E content provides antioxidant benefits.
  • Thought to help diminish signs of aging like wrinkles
  • Creates a hard, long-lasting bar of soap
  • It has very little odor, so it won’t interfere with scents.

With all these skin-loving nutrients and moisturizing properties, it’s easy to see why rice bran oil is so popular in soap recipes. It brings exceptional qualities to cold-process soap that nourish skin beautifully.

What Percentage of Rice Bran Oil Should I Use?

When formulating a cold-process soap recipe using rice bran oil, a usage rate of 10-15% is common. Rice bran oil has a high percentage of fatty acids that contribute to moisturizing qualities, so you only need a small amount to get wonderful skin benefits.

Some artisan soap makers like to use even higher amounts of rice bran oil in their recipes, sometimes up to 50–70%. At these super-high percentages, you may need to tweak the rest of your oil blend to achieve a bar with the right hardness and lather. But with some testing, rice bran oil can be the star ingredient!

What Skin Types Benefit From Rice Bran Oil Soap?

The nourishing lipids and antioxidants in rice bran oil make it excellent for mature skin types. It helps hydrate and smooth wrinkled or dry skin wonderfully. Those with conditions like eczema, psoriasis, and dermatitis may also find relief using cold-process soap containing rice bran oil, thanks to its anti-inflammatory and deeply moisturizing properties.

Of course, rice bran oil soap benefits all skin types, even sensitive ones. The vitamins and essential fatty acids nourish and protect skin for anyone looking to care for their face and body with handmade soap.

Does Rice Bran Oil Produce Lather in Soap?

Rice bran oil contains high levels of oleic acid, which is a monounsaturated omega-9 fatty acid. Oleic acid is known to boost lathering capability in soap. So while rice bran oil won’t create a thick, bubbly lather on its own, when combined in a well-balanced recipe, it absolutely contributes to a nice, stable lather in cold-process soap.

What Other Oils Combine Well with Rice Bran Oil?

Some oils that complement rice bran oil nicely in cold-process soap recipes include:

  • Olive oil for additional moisturizing
  • Coconut oil for bubbly lather
  • Palm oil for hard bars
  • Castor oil, for thick lather
  • Jojoba oil: to nourish the skin

Experimenting with different rice bran oil blends is part of the creativity and fun of soap-making!

Does Rice bran Oil Help with Lye?

Rice bran oil has a high percentage of fatty acids that react well during the saponification process to convert lye into a gentle soap. About 88% of the fatty acids in rice bran oil will chemically transform through saponification. This high conversion rate is excellent for cold-process soap.

So yes, rice bran oil works very well with lye to create a great bar of nourishing soap through the cold process method.

Here are some helpful tips when working with rice bran oil in cold-process soap:

  • Start with 10–20% rice bran oil in your first recipe.
  • Mix the lye water and let it cool completely before adding rice bran oil to prevent overheating.
  • Use full water replacement with rice bran oil to achieve the best results.
  • Blend together all the oils in the recipe before adding lye water.
