What Are Dr. Bronner's 18-in-1 Uses? The Complete Guide
If you've ever picked up a bottle of Dr. Bronner's All-One Magic Soap and tried to read the label, you'll know the '18-in-1' claim is one of the most searched-for mysteries in natural personal care. Here's the short answer, followed by a full breakdown of exactly how to use it, for your body, your home, and everywhere in between.
The quick answer
Dr. Bronner's 18-in-1 All-One Magic Soap is a single, concentrated, biodegradable soap that can be diluted and used across the body, the home, and even the laundry basket. Depending on dilution, the same bottle works as a face wash, body wash, shampoo, shaving soap, hand wash, mouth rinse, laundry soap, washing-up liquid, all-purpose household cleaner, floor cleaner, produce wash, pet shampoo, and more, replacing a whole cabinet of single-purpose bottles with one plant-based formula.
Full list: how to use Dr. Bronner's 18-in-1 soap
On the body
● Face wash — a few drops on damp skin, rinsed off
● Body wash / shower gel — lather directly or with a cloth or sponge
● Shampoo — diluted, as a gentle alternative to standard shampoo
● Shaving soap — lather in place of shaving foam
● Hand wash — for the sink or as a refill for a foaming pump
● Baby wash — the unscented Baby Mild variant is formulated without added fragrance oils, making it a popular choice for babies and sensitive skin
Around the home
● Washing-up liquid — a small amount cuts through grease
● All-purpose surface cleaner — diluted in a spray bottle
● Floor cleaning / mopping — a capful in a bucket of warm water
● Laundry soap — a natural alternative to standard detergent (best paired with a water softener in hard-water areas)
● Produce wash — diluted, to rinse fruit and vegetables
● Pet shampoo — diluted for washing pets
Because everything starts from one concentrated base, the exact dilution changes depending on the job — a few drops for a face wash, considerably more diluted for a household spray. Our full dilutions cheat sheet breaks down the ratios for every use case.

Can I use Dr. Bronner's as toothpaste or mouthwash?
Dr. Bronner's liquid soap itself isn't designed as a toothpaste substitute — but the brand does make a dedicated All-One Toothpaste, built on the same natural, simple-ingredient philosophy as the soap range, for anyone looking for a more natural addition to their bathroom cabinet.
Is Dr. Bronner's good for laundry?
Yes — diluted Pure-Castile Soap is a popular natural alternative to conventional laundry detergent, particularly for households moving away from synthetic fragrances and preservatives. It works best in soft to moderately hard water; in hard-water areas, pairing it with a natural water softener (such as washing soda) helps prevent the mineral build-up that can leave clothes feeling stiff.
What's the best Dr. Bronner's soap for babies?
Baby Mild is the variant most commonly recommended for babies and those with sensitive skin, as it's made without the essential oils found in scented versions. It's gentle enough for top-to-toe washing and doubles as a mild household cleaner for nurseries and children's spaces.

Can I use Dr. Bronner's soap on a new tattoo?
Castile soap is a frequently recommended option for tattoo aftercare thanks to its simple, gentle, fragrance-conscious formulation. A mild, unscented wash — used sparingly and diluted — is generally preferred over heavily perfumed shower gels while new ink is healing. Always follow your tattoo artist's specific aftercare advice.

What is castile soap, and how is it different from regular soap?
Castile soap is a plant-oil-based soap traditionally made from olive oil (Dr. Bronner's uses a blend of organic coconut, olive, palm kernel, and hemp oils), rather than animal fat or synthetic detergents. It's biodegradable, highly concentrated, and works up a rich lather even when heavily diluted — which is exactly why one bottle can be stretched across so many different uses.
Which scent should I choose?
All scents share the same 18-in-1 versatility; the difference is in the essential oils used. Peppermint is the brand's best-known, most invigorating option. Tea Tree and Eucalyptus are popular for their fresh, clarifying scent and are seeing growing interest month on month. Lavender offers a calmer, more soothing alternative, and unscented Baby Mild is the go-to for sensitive skin.
