Want to know what goes into smol products… and what we leave out?
Here’s everything you need to know about our ingredients, why we use them (or don’t), and how we make sure they’re safe for you and the planet. But first, a quick note on what our concentration means…
… the aquatic life warning.
All our products are super concentrated to reduce packaging and transport emissions. That’s why you’ll sometimes see an aquatic life warning on our labels (it’s a legal requirement for concentrated products). Once diluted for use, smol products are not classified as a concern. The warning only applies if the undiluted product were to spill into a waterway in extremely large quantities (e.g. an industrial accident), which is extremely unlikely.
