If you're a liquid lover, you're in the right place.
We created smol Laundry Liquid because liquid laundry detergent needed an overhaul.
Most laundry liquids are surprisingly diluted. In fact, some big-brand detergents are as much as 80% water.¹
Ours is different.
It uses up to 42% less liquid per wash than the big brands, yet still matches them on the clean.
Less liquid. Same brilliant clean.
Because smol Laundry Liquid is up to 45% more concentrated than many big brand liquids¹, you simply need less product every time you wash.
- Uses up to 42% less liquid per wash than the big brands.
- Powerful stain removal.
- No SLS or foam boosters.
One brilliant formula. Two bottles to choose from.
100% recycled aluminium or 100% recycled plastic.
Whichever bottles-for-life you choose, simply refill them using our compact laundry liquid cartons whenever you're running low.
Same brilliant formula. Same refill cartons. Just the bottle that suits you.
Why refill?
Buying a brand new plastic bottle every time you run out of detergent has become the norm.
We don't think it should be.
Our refill cartons use 83% less plastic than traditional laundry liquid bottles and create 43% less carbon during production than a recycled plastic bottle.¹
On top of that, each refill pack saves you around 275g of plastic, and an average family can save around 2kg of plastic every year by making the switch.¹
Brilliant on modern washing.
Today's laundry looks very different from twenty years ago because we tend to wash on colder and quicker cycles to save time and energy where we can.
That's exactly what smol Laundry Liquid is designed for.
Our formula delivers brilliant stain removal even on 15-minute quick washes.
Independent testing found our Non-Bio Laundry Liquid matched Persil Wonder Wash Non-Bio on a 15-minute cycle overall, while keeping whites whiter and performing better on grass stains.¹
So there's truly no need for a specialist "quick wash" detergent.
