Naturally Refreshing Peppermint Castile Soap
Peppermint (Mentha piperita) is one of the world's most recognisable botanicals, treasured across cultures for centuries. Its leaves are rich in menthol — the compound behind that iconic cool, clean sensation and unmistakable fresh fragrance.
Our Peppermint castile soap is a natural, multipurpose cleaner built around this single invigorating botanical: cool, clean, and traditionally valued for its refreshing qualities. The result is a castile soap that doesn't just clean — it refreshes, energises, and fills your home with the crisp scent of pure peppermint.
A Multipurpose Natural Cleaner for the Whole Home
One bottle of peppermint castile soap replaces a cupboard full of single-use cleaning products:
Personal care: hand and body wash, shower gel, facial cleanser (diluted), clarifying shampoo, cooling bubble bath
Household cleaning: kitchen surface cleaner, bathroom cleaner, floor cleaner, all-purpose spray, streak-free glass and mirror cleaner
Laundry & dishes: natural laundry detergent, eco-friendly dish soap, hand-washing delicates
Also great for: pet washing (avoid eyes and face), car washing, outdoor furniture, vegetable wash (properly diluted)

Body & hair: use undiluted or slightly diluted — apply to wet skin or hair, lather, rinse
-
Hands: 1 tbsp per 250ml water in a foaming dispenser
-
Household cleaning: dilute 1:10 for general surfaces, 1:20 for floors
-
Dishes: a squirt directly on dishes, or diluted in the sink

It's concentrated, so a little goes further than you'd expect — dilute for the task at hand.
Make It Yours
Add a few extra drops of peppermint or complement it with spearmint for a softer, sweeter mint. Or build your own blend with eucalyptus for a spa-like steam effect, tea tree for an extra fresh, medicinal edge, or lavender for a calming mint blend. See our recipes for ideas on turning this into foaming hand soap, body wash, kitchen spray, or scalp shampoo.
