16oz = 32-64 loads
32oz = 64-128 loads

Castile Soap (Coconut Oil, Distilled Water, Sodium Hydroxide), Sodium Bicarbonate, Sodium Tetraborate, Sodium Carbonate, Pure Essential Oils* (not included in unscented)

* A note about rosewood: Did you know that rosewood (Aniba rosodora) is classified as an endangered species due to urban development, agriculture, and logging? But don't worry - you can still enjoy the floral, earthy delight of rosewood in our natural laundry detergent, because it doesn't actually contain rosewood! Our rosewood detergent is scented with a blend of essential oils created to mimic the smell of rosewood, without harming endangered species.

To Use

For machine washing: Sprinkle the laundry detergent directly into the drum before adding laundry (yes, you can do this with high-efficiency machines, too!). For regular machines use just one tablespoon of detergent, or 1/2 tablespoon for high-efficiency machines.

Pro-tip: For machines without an agitator, add the detergent in a donut shape to the drum. Thank you to EcoWarrior Jessica for this sustainable laundry tip!

For hand-washing: Fill your sink or a bucket with warm water, and sprinkle in ½ or 1 tablespoon of laundry detergent and stir until it’s dissolved. Add your delicates and gently wash as you normally would by hand. Rinse clean with fresh water.

As a stain releaser: Mix a small amount of our laundry detergent with a bit of water to create a watery paste. Apply the paste directly to stains and let it sit for 15-20 minutes, then add to your washer and wash as normal.

Packaging + End of Life

Our refillable natural laundry detergent is packaged in a glass jar with a metal lid or in a reused plastic bag.

When you’re running low on detergent, order another jar here, but choose “Refill Jar” or "Refill Bag." When you order a Refill Jar, we’ll include a return label for your old jar so you can send it back to us at no cost. We’ll sanitize and reuse the jar. (If you're in our local delivery radius, just leave your empty jar on your porch on delivery day!)

* What's up with the plastic bag?

Our caps and pumps come to us in plastic bags. It's one of those things that's out of our control. We've been saving these bags since we launched in 2019, trying to figure out what to do with them. In November 2021, we took to Instagram to find out how you, our EcoWarriors, would feel about using them for shipping laundry detergent. Overwhelmingly you all voted to reuse them. So we've added this as an option!

Now here's what you need to know...

  • These bags are intended for shipping only, not delivery. The bags reduce weight in shipping and therefore cut costs for both you and us. We also only have a limited amount of these bags. If you are within our delivery radius, we kindly ask that you please choose a jar option, as that is the most sustainable option for delivery.
  • We will not be taking these bags back for reuse. We do not have a way to wash and sanitize them effectively.
  • We will never purchase plastic bags for this purpose. If we run out, we run out. At that point, then, the only options will be the jars.

We're so grateful to have a community of EcoWarriors that values progress over perfection, and reuse over new. Thank you for helping us give these bags another life!

🌎 You care about the planet. So do we.

Look. I get it. It’s HARD to be an EcoWarrior. Someone who cares about the planet and wants the most sustainable products available - from the ingredients to the packaging to the way that product gets to your hands.

It seems like everywhere we turn, someone, somewhere, is greenwashing us.

But our superpower at A Drop in the Ocean is sorting through the BS, calling it out, and making sure our products are the absolute most sustainable and truly zero waste products we can find.

So on top of all the things we mentioned above about what makes our zero waste laundry detergent so sustainable, here’s a few other things you should know:

  • We’re actually practicing what we preach behind the scenes. In 2022, we saved all of our trash for four months, and wrote a whole blog post on it. The tl;dr version is this: in four months, we only produced two pounds of trash. Everything from the packaging our products come in down to the Sharpie we use to write “Fragile” on your box is zero waste to its core.
  • We’re an online-only zero waste store - which is highly intentional. It may seem counter-intuitive, but online shopping is actually more sustainable than in-person. I’m a data nerd at heart and I love diving into the research, and there are countless studies that have shown that online shopping is the most sustainable way to get your everyday essentials. Don’t believe me? Check out our whole blog post on the sustainability of online shopping.
  • We ship ugly boxes. Your order from A Drop in the Ocean is not going to arrive in a pretty, branded box. It’s gonna show up in a reused tea box, or a donated Amazon box, or maybe even an inside-out Girl Scout Cookies box. All of our shipping materials are always 100% plastic-free and reused as much as possible, with curbside-recyclable paper tape and a post-consumer recycled paper shipping label. It won’t be pretty, but it will be zero waste.

Got more questions about our zero waste products or our practices behind the scenes? Just send us an email! I’m always happy to chat all things eco.

How Our Refill Program Works

Order Your First Refillable

On your first order, choose the "New Jar" or "New Bottle" option.

Get Your Refillable

Your order will be shipped or delivered to you with minimal, reused, packaging. Always plastic-free and carbon neutral.

Order Your Refill

When you're running low, place another order using the "Refill Jar" or "Refill Bottle" option. Or choose the Subscribe + Save option to have refills automatically delivered on your schedule.

{Delivery Only} Leave Us Your Empties

On delivery day, leave your empties on your porch. We'll grab them when we drop off your new order.

Get Your Refill

We'll ship or deliver your refill to you without any pumps or sprays - just a cap. Transfer any pumps or sprays from your old bottle to the new one, and transfer the refill lid to the old bottle.

{Shipping Only} Send it Back!

Pack your empty bottle or jar into the box your refill arrived in. Place the included return label on the box, fully covering the existing label, and hand it off to USPS to come back to us - at no charge to you

I stumbled across A Drop in the Ocean on my quest to reduce our family's plastic use. I have a small family and live in a rural area with only a few big box stores and zero plastic recycling options. Finding plastic free items locally can be a challenge. I was thrilled to find a shop in my home state that would reuse returned glass and aluminum bottles. I'm a repeat customer as the products are excellent and the shop owner makes it super simple to return our used bottles by mail.

Subtle scent; Effective cleaner

I love the subtle clean scent of eucalyptus that doesn't overpower or even linger. Better yet is the reliable cleaning power of this powdered laundry detergent. I appreciate that the product is sustainably made and reasonable priced. I will most certainly reorder - and urge you to try it if you haven't already.

Terrible service

I haven't received my product, they stuffed up my order, still waiting.... Alot of money down the drain.

Hi Paul - As I mentioned in my email, I am so sorry that your order was rerouted back to our office. I believe something was updated with USPS regarding international shipments and while I was able to process and ship your order right away, apparently once it tried to leave the country something got flagged. As soon as it arrived back at my office, I emailed you to let you know what was going on and that I would figure out the problem ASAP. I did figure it out and it's back on its way to you now via UPS, scheduled to arrive on May 15. I emailed you as soon as I shipped it back out to give you an update, and you also should have received a new tracking number, but if you did not I'm happy to send it to you via email so you can keep an eye on it too. I've been checking it every day to make sure it's still in transit and everything is looking good so far! I do apologize for the delay. This was a learning experience for me for sure and I appreciated the patience you expressed to me via email. I'll keep watching the UPS tracking, and I hope that you love your dryer balls and laundry detergent when they arrive on your doorstep in a few days! Please feel free to email me with any other questions you have.

Beautiful Detergent

This detergent smells so wonderful! I've used it once so far in my cold water only, Black&Decker portable washing machine. It worked great! No residue was left behind and my clothes smelled so clean!
