Key Takeaways
-
Choosing an eco-friendly laundry detergent shouldn’t mean compromising on cleaning performance. Look for specific performance testing rather than relying on marketing claims alone.
-
A detergent is worth evaluating across five areas: stain-removal performance, format and dosing, third-party certifications, price per load, and ingredient transparency.
-
Pre-measured formats like tablets can also take the guesswork out of dosing. Research has shown that the size of a detergent dosing aid alone can influence how much detergent people use.
-
Environmental claims are only one part of the equation. The formula still needs to clean effectively, and independent testing and third-party certifications can help you evaluate what’s behind the claims.
How We Test
Blueland Laundry Tablets have undergone independent, third-party testing alongside five major laundry pac and liquid detergent brands across ten common stains.
The products were tested using the same procedure, with stained fabric washed alongside additional clean fabric to mimic a full load of laundry. In cold-water testing, Blueland Laundry Tablets outperformed a major brand on 8 of the 10 stains tested.
You can see the full testing methodology and stain-by-stain results in Blueland's lab results article.
What to Look For in an Eco-Friendly Laundry Detergent
When comparing laundry detergents, look beyond the “eco-friendly” label itself. These five criteria can give you a better sense of how a detergent will actually perform and whether its environmental claims are backed by meaningful evidence.
1. Stain-Removal Performance
A laundry detergent still needs to do its main job: clean your clothes.
Instead of relying only on broad performance claims, look for testing that explains how a detergent was evaluated. Look for details on how the stains were tested, what water temperature was used, dosage, fabric type, and whether the testing was performed by an independent third party.
Blueland Laundry Tablets, for example, were independently tested alongside five major laundry brands. In cold water, Blueland outperformed a major brand on 8 of the 10 stains tested.
Cold-water performance can be particularly useful when evaluating a detergent because washing clothes in cold water can reduce the energy used to heat water during a laundry cycle.
2. Format and Dosing
Laundry detergent comes in several formats, including liquids, powders, sheets, pods, and tablets. The format can affect packaging, shipping weight, convenience, and how the detergent is dosed.
Pre-measured formats remove the need to measure detergent for every load and reduce unnecessary waste from using too much. With Blueland Laundry Tablets, for example, the standard dose is a single tablet.
When comparing formats, also look at how the detergent is packaged and delivered. Blueland Laundry Tablets are dry, concentrated, and not individually wrapped in PVA.
3. Third-Party Certifications
Rather than relying only on vague environmental language, look for certifications from independent organizations with published standards like EPA Safer Choice.
To qualify for the Safer Choice label, products must meet EPA requirements that include ingredient criteria as well as product-level requirements. The EPA evaluates every chemical ingredient in a formulation against its applicable human health and environmental criteria.
Other certifications can evaluate different parts of a company’s products, practices, or environmental impact, so it’s worth understanding what each certification actually covers rather than treating every certification as interchangeable.
Blueland products have earned certifications including EPA Safer Choice and Cradle to Cradle, and Blueland is a Certified B Corporation. You can learn more about Blueland’s certifications and what each evaluates here.
4. Price Per Load
Sticker price doesn’t always make it easy to compare detergents across different formats and package sizes.
Instead, calculate price per load:
Price per load = total product price ÷ number of rated loads
Make sure you’re comparing products based on the recommended dose for a standard load, which gives you a more consistent comparison between tablets, liquids, powders, and other formats.
5. Fragrance and Ingredient Transparency
If ingredients matter to you, look for brands that make their ingredient lists easy to find and understand.
Check whether the brand publishes its ingredients, explains their functions, and offers third-party certifications that evaluate the formula against published standards.
If you prefer to avoid added fragrance, you can also look for a fragrance-free option rather than relying on broad marketing terms to understand what’s in the product.
Blueland publishes its product ingredients and offers both scented and fragrance-free options.
Frequently Asked Questions
Do eco-friendly detergents work as well as conventional detergents?
Cleaning performance depends on the individual formula, dose, stain, and wash conditions, not simply whether a detergent is described as eco-friendly.
That’s why specific performance testing can be more useful than the label alone. Blueland Laundry Tablets have undergone independent, third-party testing alongside five major laundry brands. In cold-water testing, Blueland outperformed a major brand on 8 of the 10 stains tested.
What certifications should I look for in an eco-friendly laundry detergent?
Look for certifications with clear, published standards that tell you what was actually evaluated.
For example, EPA Safer Choice evaluates every chemical ingredient in a certified product against applicable human health and environmental criteria and also has product-level requirements. Other certifications may evaluate areas such as materials, product design, or broader company practices.
Rather than looking for one particular logo, check what each certification covers and whether it applies to the specific product you’re considering.
What is the best eco-friendly laundry detergent for stains?
There isn’t one detergent that will necessarily perform best under every wash condition. Results can vary based on the stain, dose, water temperature, fabric, and washing machine.
Look for independent testing that clearly explains those conditions rather than relying on a general performance claim.
