Why choose Mme L’Ovary’s laundry capsules?

They’re effective, made from natural ingredients, and environmentally friendly. Our soap erases blood stains and is essential to the long life of your menstrual undies. They’re easy to use and naturally fit into your laundry routine.

An effective and biodegradable detergent

Just like the soaps we use for our intimate areas, our detergent was carefully designed to be as effective as it is natural. We’ve developed a formula from natural ingredients known and recognized for their many virtues, including tea tree essential oil.

You can remove blood stains efficiently and effortlessly while respecting your undies’ fabric and delicate textile fibers.

Your menstrual undies come out fresh after every wash. Cycle after cycle, your undies maintain their high quality.
