About Butter & Lye

Non-toxic, Eco-friendly Bath and Body Solutions that care. I'm Monique Kofsky, an entrepreneur, wife, biochemist, and mom. I’ve always been passionate about gentle, natural skincare, and after years of searching for a toxin free solution for my sensitive skin, I decided to take matters into my own hands. By marrying ancient soap-making traditions with modern scientific knowledge, I created soaps with clean ingredients that effectively sooth and nourish your skin.

That’s when I launched Butter & Lye, a small business based in Brooklyn, New York, dedicated to providing top-quality, nontoxic solutions for sensitive skin. At the heart of everything we do here is care and kindness — for our customers, our community, and the environment.

Every sale supports our community- For every bar of Butter & Lye soap purchased, we donate a bar to someone in need who could use that morsel of joy. It’s all about giving back.

We protect the earth- Sustainability is central to everything we do. Along with our natural ingredients, our eco-friendly packaging and clean ingredients minimize our impact on the environment. I want to do my part to take care of the planet for my son, his children, and the generations that come after them.
