Why Leo?

  • 01

    We leave something behind with every wear and we can feel it.

    Sweat, skin oils, and food work into fabric with every wear, and a regular wash doesn't always get it all out. That can leave clothes feeling dingy.

    Leo's answer: Lipase targets oils and fats, so they can rinse out instead of stacking up.

  • 02

    Your detergent shouldn't compete with your fragrance.

    Scented detergent adds a second fragrance to everything you wear.

    Leo's answer: No fragrance at all. What you wear is all you smell.

  • 03

    You just pulled it out of the dryer, but you can still feel it.

    High sudsing detergents can leave a film that stiffens fabric, reduce pliability and just doesn't feel right.

    Leo's answer: Concentrated and low-sudsing with a short ingredient list, built to rinse out.

  • 04

    Your clothes aren't wearing out, they're being washed out.

    Good fabric is meant to last, and replacing it adds up. Think of what that money could do instead.

    Leo's answer: No optical brighteners or dyes which can build up on fabric making them less pliable and more susceptible to friction damage during the wash cycle. Formulated with fabric life in mind.

Built for all of it.

What's in Leo.

Every ingredient, and what it does.

Target

2 ingredients
  • Lipase
  • Amylase

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

3 ingredients
  • Sodium C14-16 olefin sulfonate
  • Lauramine oxide
  • Myristamine oxide

Cleaning agents called surfactants. They lift oils and dirt off fabric and hold them in the wash water so they rinse away.

Carry

2 ingredients
  • Water
  • Sodium chloride (salt)

Water carries everything else through the wash. Salt helps the formula keep its body.

Protect

2 ingredients
  • Methylchloroisothiazolinone
  • Methylisothiazolinone

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.
