Real Standards. Real Skincare.
At William Brook, we take formulation seriously—not just in the ingredients we choose, but in how our products are made. That’s why every jar of tallow balm and every bottle of oil is manufactured in a facility that complies with the FDA’s Modernization of Cosmetics Regulation Act (MoCRA), one of the most significant updates to cosmetic safety laws in over 80 years.
What the heck is MoCRA?
If you’ve never heard of MoCRA, you’re not alone. But here’s why it matters: MoCRA sets clear, modern safety standards for cosmetics manufacturing in the U.S., including ingredient transparency, facility registration, good manufacturing practices (GMP), and mandatory adverse event reporting.
In plain English? It means our products are made in a clean, professionally regulated space, where hygiene, consistency, and traceability aren’t optional—they’re required.
This might seem like a prerequisite for any product that goes on your skin. But the truth is, most tallow-based skincare on the market is still made in unregulated home kitchens and garages—sometimes by passionate people, but rarely with proper controls or oversight. That means no guarantees around cleanliness, ingredient purity, or even shelf stability.
We don’t think that’s good enough.
When you use William Brook, you’re not taking a chance on a mystery batch. You’re choosing skincare that’s produced in a facility where every step is documented, every ingredient is traceable, and every product meets rigorous standards for quality and safety. We blend the richness of tradition with the precision of modern formulation—so you get the best of both worlds.
