Key features & specs

How it compares

When compared to conventional synthetic detergents, Dr. Bronner's offers superior environmental safety without the use of foaming agents like SLS or SLES. While mainstream cleaners often rely on artificial perfumes, the Peppermint variety uses steam-distilled essential oils that provide a cooling sensation and natural antimicrobial properties.

Against other natural plant-based soaps, the high concentration of Dr. Bronner's provides a significantly lower cost-per-use, though it requires users to be comfortable with manual dilution math. It excels over petroleum-based alternatives by ensuring no microplastics or harsh residues are left on home surfaces.

How to use it

1. For all-purpose surface cleaning, add 1/4 cup of soap to a quart of water in a spray bottle.
2. For mopping floors, dilute 1/2 cup of soap into 3 gallons of hot water.
3. To wash dishes by hand, dilute the soap 1:10 with water or apply a small drop to a wet sponge.
4. For laundry, use 1/3 to 1/2 cup for a large load in a traditional washer (scale down for HE).
