Curd soap

Rediscover the lost art of curd soap

Welcome to a journey back in time, where tradition meets sustainability with the revival of curd soap—the ultimate, old-fashioned soap crafted just like our grandmothers used to make. This is more than just a soap; it’s a piece of history, perfected over generations and cherished for its incredible versatility and minimal impact on the environment.

These are not soaps made using the cold or hot process; these are soaps made using the full boiling method with salting out, exactly the way our grandmothers used to make them in a cauldron. Soaps that are powerful in cleaning and less suitable for the skin, but excellent for laundry and household use.

Handcrafted heritage for everyday use

Curd soap is more than an ordinary soap—it’s an essential, all-purpose cleaner, best thing ever for removing stubborn stains from laundry, base for natural washing machine “detergent” and many other cleansing remedies, cleaning up after pets and horses, tending to ulcer wounds, and even cleansing makeup brushes. No modern cleaner captures the same effectiveness and simplicity. This timeless formula was once a staple in every household, and today, we bring it back for you with a focus on quality and sustainability.

Why soap makers are eager to master curd laundry soap from waste oils and scraps

Environmentally friendly

If you’re already experienced in soap making, learning to make curd soap can add a valuable new dimension to your skills. Curd soap is a traditional, heavy-duty soap that uses a unique de-salting process, making it perfect for laundry and household cleaning.

Not only is curd soap an economical choice for customers, but it’s also a profitable one for you, made from recycled oils that reduce waste. And also, you can even use all your rancid soaps :-).

Join this course to learn every step of the process and gain the skills to produce a high-demand, versatile soap that adds value to your business and helps you increase profits.
