Why Tallow Is the Star Ingredient in Our Soaps
Let’s talk about tallow—an ingredient that’s been used in soap for centuries, tossed aside for a while, and now finally getting the respect it deserves. At Boston Soap Co., we use tallow in our bars for a few very good reasons: it works, it lasts, and it’s better for your skin than the trendy stuff.
What Is Tallow, Anyway?
Tallow is rendered beef fat, usually a byproduct of the meat industry. Sounds old-school? That’s because it is. But don’t let that fool you—this traditional ingredient is a skin-nourishing powerhouse that blows most commercial soap bases out of the water.
What Makes Tallow So Good for Skin?
-
🧼 Rich, Creamy Lather
Tallow makes a thick, lotion-like lather that feels amazing on your skin. Not too bubbly, not too drying—just right. -
💧 Deep Moisture
Tallow is packed with fatty acids like oleic and stearic acid, which are similar to what’s found naturally in our skin. That means your skin recognizes it and actually benefits from it. -
🧱 Harder, Longer-Lasting Bar
Nobody wants a bar of soap that turns to mush. Tallow makes a solid, long-lasting bar that can handle showers, sinks, and the test of time. -
♻️ Sustainable & Local
We source our tallow from farms in Massachusetts. It’s a smart use of an ingredient that would otherwise be wasted, and way more eco-friendly than palm oil or synthetic alternatives.
Not Just for Grandma’s Soap
We get it—"beef fat in soap" might not sound trendy. But once you try it, you’ll get it. Tallow is making a comeback because it’s gentle, effective, and natural. No gimmicks, no fillers—just real skincare that works.
Where You’ll Find It
You’ll find tallow in most of our bars—especially our Massachusetts Grown Boston Made Tallow Soap and our Honey Milkies, made with tallow, lard, and raw goat’s milk from Herb Hill Micro-Dairy in Pepperell, MA.
