tallow in soap
Now that we understand real soap is made with various oils/fats and lye, we can consider the benefits of different types of oils/fats, including tallow.
When people think about soapmaking today, they often picture olive oil, coconut oil, or trendy butters like shea and cocoa. But long before these ingredients became popular in modern recipes, tallow—rendered beef fat—was the cornerstone of traditional soapmaking. It’s one of the oldest and most reliable ingredients for creating a gentle, long-lasting bar of soap.
what is tallow?
Tallow is beef fat that has been rendered (purified by heating and straining). While it may sound unusual, it was historically the most common base for soap and candles. Cultures all over the world used it, and for good reason: it was plentiful, sustainable, and made a soap that was both functional and skin-friendly.
benefits of using tallow in soap
1. Creamy, Stable Lather
Tallow creates a creamy, rich lather that feels smooth on the skin. While it doesn’t produce the big bubbles that coconut oil does, it balances the bar by adding silkiness and mildness.
2. Hard, Long-Lasting Bar
A soap made with tallow cures into a firm bar that lasts much longer in the shower than many all-vegetable oil soaps. This makes it practical as well as economical.
3. Gentle and Nourishing
Tallow’s fatty acid profile is similar to human skin’s natural oils. This helps it lock in moisture and makes it especially suitable for sensitive or dry skin.
4. Sustainable Choice
Since tallow is a byproduct of the meat industry, using it in soap helps reduce waste. It’s a way of honoring the whole animal and making use of something that would otherwise be discarded.
is tallow soap old-fashioned?
Some may see tallow soap as outdated, but in reality, it’s making a comeback among natural soap enthusiasts. More people are recognizing its benefits for skin health, its sustainability, and its connection to traditional craftsmanship.
back to basics
Tallow in soap may feel like a “back to basics” approach, but that’s exactly what makes it so special. It’s simple, effective, and rooted in history—yet still perfectly suited to modern natural skincare. Whether blended with plant oils or used as a main base, tallow soap delivers a luxurious, skin-friendly experience that has stood the test of time.
