What's in Leo.
Every ingredient, and what it does.
Target
- Lipase
- Amylase
Target
Enzymes that break down specific soils. Lipase works on oils and fats. Amylase works on starches. Broken into smaller pieces, they rinse out more easily.
Clean
- Sodium C14-16 olefin sulfonate
- Lauramine oxide
- Myristamine oxide
Clean
Cleaning agents called surfactants. They lift oils and dirt off fabric and hold them in the wash water so they rinse away.
Carry
- Water
- Sodium chloride (salt)
Carry
Water carries everything else through the wash. Salt helps the formula keep its body.
Protect
- Methylchloroisothiazolinone
- Methylisothiazolinone
Protect
A preservative. Liquid detergent is mostly water, and water-based products can grow bacteria and mold in the bottle. This keeps Leo fresh from the first pour to the last. We use a very small amount: less than 0.002% of the formula.
Worth knowing. Isothiazolinones can cause skin reactions in some people. If you have very sensitive skin, Leo isn't the right detergent for you.
What we left out
- Fragrance Nothing to compete with the one you chose.
- Dyes Color does nothing for the wash.
- Optical brighteners They make fabric look brighter, and can build up on it over time.
- SLS and SLES Common cleaning agents. We chose a different system.
- Phosphates Restricted in many places for their impact on waterways.
- Chlorine bleach Can fade color and wear fabric.
- Parabens We use a different preservative, named above.

Clean truths.
Three things most people get wrong about laundry.
“If your laundry smells fresh, it's clean.”
The truth.
The fresh smell people call clean is usually fragrance added to the detergent. A fresh scent doesn't prove the clothes are clean.
Leo is fragrance-free, so the only fragrance on your clothes is the one you choose.
“The outside of your leggings is the dirtiest part.”
The truth.
It's the inside. Body oils and sweat collect there, which is why turning them inside out also protects the outer fabric from rubbing in the wash.
One of Leo's two enzymes, lipase, targets oils and fats.
“Jeans need washing after every wear.”
The truth.
Jeans, sweaters, and jackets can usually go several wears. Tees, underwear, and workout clothes still go in after each wear.
Fewer washes, and when you do wash, Leo is formulated with fabric life in mind.
“More detergent means cleaner clothes.”
The truth.
Extra detergent can leave residue that traps dirt and body oils, and makes fabric feel stiff and look dull.
Leo is concentrated and low-sudsing, built to rinse out.
“Fabric softener is great for gym clothes.”
The truth.
Softener works by coating fibers, and activewear care guides say that can hurt how well fabric wicks sweat.
There's no softener and no fragrance in Leo.
“Sweaty gym clothes are fine in the bag until the weekend.”
The truth.
Wicking fabric can become a breeding ground for bacteria and yeast if left unwashed. Wash after each workout, or hang them to air out.
Leo is built for people who sweat in their clothes.
“Hanging a sweater keeps it in shape.”
The truth.
A hanger pulls the sweater's weight onto its shoulders, which can stretch them out. Fold it, or fold it over the bar.
Leo is formulated with fabric life in mind. The folding is on you.
“Dryer heat won't hurt stretchy fabric.”
The truth.
Heat can make fibers warp and lose their stretch. Hang or air dry activewear when you can.
Leo has no optical brighteners, which can build up on fabric.
“A packed washer cleans just as well as a half-full one.”
The truth.
Overstuffed washers can leave residue behind on clean clothes. Give your clothes room to move and rinse.
Leo is built to rinse out. Giving it room to is up to you.
