“Free & clear” and “plant-based” do not tell you the whole formula. Seventh Generation Concentrated Free & Clear and ECOS Hypoallergenic Free & Clear are both fragrance-free liquids with EPA Safer Choice certification, but their ingredient lists, dosing instructions, enzymes, and product-specific eczema recognition differ.
The first step is to compare the exact bottles. Seventh Generation’s EasyDose liquid and laundry packs are not interchangeable with its 40 or 50 fl oz concentrated liquid. ECOS also sells several formats and an enzyme version. This article covers the standard ECOS Free & Clear liquid without enzymes.
| Factor | Seventh Generation Concentrated Free & Clear | ECOS Hypoallergenic Free & Clear |
|---|---|---|
| Liquid sizes checked | 40 and 50 fl oz | 50, 100, 170, and 210 oz |
| Fragrances and dyes | Manufacturer says none | Manufacturer says no added fragrances or dyes |
| Ingredients on current product page | 12 | 6 |
| Enzyme blends listed | Protease, amylase, and mannanase | None in the standard formula |
| Preservatives listed | Benzisothiazolinone and methylisothiazolinone | Phenoxyethanol and methylisothiazolinone |
| EPA Safer Choice | Yes | Yes |
| USDA Certified Biobased claim on product page | 96% | No percentage stated on the page checked |
| National Eczema Association listing verified | Packs are listed; this liquid was not verified as the listed product | The liquid is listed, but the directory and manufacturer ingredient lists differ |
| Medium HE dose stated by manufacturer | 0.75 fl oz / 22 mL | 1 fl oz |
| Freshly Folded detergent menu | 7th Generation is included; confirm the exact stocked SKU | Not one of the five listed choices |
Choose from the facts that matter to your routine. Seventh Generation lists three enzyme blends and a 96% biobased certification for this liquid. ECOS lists a shorter formula and different dosing for HE and standard washers. Neither set of facts proves that one product will clean every stain better or suit every person’s skin.
The current Seventh Generation Concentrated Free & Clear product page covers 40 and 50 fl oz bottles. It lists water, cleaning agents, water softeners, three enzyme blends, and two synthetic preservatives: benzisothiazolinone and methylisothiazolinone.
The same page says the liquid has no fragrances, dyes, or artificial brighteners. It gives a medium-load dose of 0.75 fl oz and identifies the product as EPA Safer Choice certified and 96% USDA Certified Biobased Product.
Those details cannot be transferred to every Seventh Generation item. EasyDose has a separate ingredient list, dose, and 99% biobased claim. The packs have a separate 94% claim and their own certification record. If the bottle is not the 40 or 50 fl oz concentrated liquid, reopen the comparison using that product’s current page.
The current ECOS Hypoallergenic Free & Clear product page lists six ingredients: water, three plant-derived surfactants, phenoxyethanol, and methylisothiazolinone. It does not list an enzyme in the standard formula.
ECOS directs HE users to use one ounce and standard-washer users to use two ounces. The page also identifies the product as EPA Safer Choice certified and states that it can be used with septic systems or greywater tanks. Those are manufacturer statements for the named formula, not a blanket conclusion about every ECOS product.
There is an evidence wrinkle the package should resolve. The ECOS manufacturer page and the National Eczema Association ECOS listing currently publish different ingredient lists. The directory lists eight ingredients and does not show methylisothiazolinone, while the manufacturer page lists six and does. That could reflect a formula or listing update, so check the UPC and bottle label rather than combining the two lists.
The Seventh Generation liquid lists protease, amylase, and mannanase blends. Enzymes are selected to act on particular types of soil. ECOS’s standard formula relies on surfactants instead, while ECOS sells a separate Free & Clear with Enzymes product.
Ingredient theory is not a head-to-head result. Load size, water, dose, fabric, pretreatment, soil age, and cycle all affect the outcome. Without equal swatches and a documented protocol, statements such as “higher cleaning power” or “you will see the difference immediately” go beyond the evidence.
For routine use, follow the garment label and product dose. Pretreat a stain only when the detergent and fabric instructions allow it. If stain performance is the deciding factor, test the two current products under the same conditions and record the results before making a broad claim.
The EPA Safer Choice program reviews every chemical ingredient and also applies criteria for performance, packaging, pH, and volatile organic compounds. Both product pages display Safer Choice certification. EPA also makes clear that certification is a program standard, not a promise that every person will tolerate a product.
The USDA BioPreferred program uses third-party testing to verify a product’s biobased content. USDA defines the percentage through renewable “new” organic carbon relative to total organic carbon. It does not use that percentage to declare a product safer, more effective, or environmentally superior in every respect.
Seventh Generation’s current page states 96% for this concentrated liquid. The ECOS page checked for this article does not display a USDA percentage. “Plant-derived” and “USDA Certified Biobased” are therefore not equivalent claims in this comparison.
The Seventh Generation NEA entry found in the current directory is for Free & Clear laundry packs. It lists a pack formula and a 94% USDA biobased claim. It should not be presented as certification for the concentrated liquid in this article.
ECOS Hypoallergenic Free & Clear liquid does have an NEA directory entry. Because its directory ingredient list differs from the current manufacturer page, verify the package before using the seal to describe a specific bottle.
A seal can help narrow a shopping list, but the NEA itself tells people with eczema or sensitive skin to identify their own potential irritants and refer health questions to a clinician. Avoid turning directory inclusion into a treatment claim.
The current pages for both liquids list methylisothiazolinone. Seventh Generation also lists benzisothiazolinone; ECOS lists phenoxyethanol. That is relevant label information for someone whose clinician has identified a contact allergy. It is not enough to diagnose the cause of a rash.
Exposure matters. A published household machine-washing study indexed by PubMed did not detect methylisothiazolinone in washed textiles under its test conditions, even though the authors describe the preservative as a strong contact allergen. That result is a useful check on alarmist ingredient lists, but it does not establish the outcome for every formula, washer, dose, or person.
If a rash persists, a dermatologist can decide whether patch testing is appropriate. Do not change detergent, hand soap, dish soap, and skin-care products together and then claim one ingredient was responsible.
Do not compare bottle price or ounces alone. Record the retailer, date, exact size, regular price, sale price, and stated medium-load count. Divide the price actually paid by the stated load count, then compare the dosing instructions with the loads you run.
The Seventh Generation page states 53 medium loads for 40 fl oz and 66 for 50 fl oz. ECOS uses different doses for HE and standard washers, so its load count depends on the machine type. Without a dated retail table, a claim that either brand is usually cheaper or more widely discounted is unsupported.
Freshly Folded lists 7th Generation among the five detergent choices for its San Diego County wash-and-fold service. Tide, Gain, All Free Clear, and Persil are the other choices. Detergent selection is included without an additional detergent charge. Confirm the exact 7th Generation SKU before scheduling if a particular formula matters. ECOS is not on the listed menu, so contact the team before booking to ask whether a non-stocked product can be accommodated.
The pickup-and-delivery service returns laundry the next business day. Weekly wash and fold is $2.49 per pound, on-demand service is $2.69 per pound, the minimum order is $49.99, and each pickup costs $5.99. Confirm the current rates on the pricing page and check the service area directory.
For related formula questions, compare Tide Free & Gentle with all free clear or read the baby-clothes detergent comparison. Machine-washable items belong in wash and fold; care-label exceptions can be reviewed for dry cleaning pickup or pressing. The separate article on ozone in the laundry process explains that service step within its cited scope.

Which exact Seventh Generation detergent is compared here?
This article covers Seventh Generation Concentrated Laundry Detergent, Free & Clear, in the 40 or 50 fl oz bottle. EasyDose liquid and laundry packs have different formulas, doses, and biobased percentages.
Which exact ECOS detergent is compared here?
This article covers the standard ECOS Hypoallergenic Laundry Detergent, Free & Clear liquid sold in 50, 100, 170, and 210 oz sizes. ECOS Free & Clear with Enzymes is a different product.
Does standard ECOS Free & Clear contain enzymes?
The current manufacturer ingredient list for the standard ECOS Hypoallergenic Free & Clear liquid does not list an enzyme. ECOS sells a separate Free & Clear with Enzymes formula.
Does Seventh Generation Concentrated Free & Clear contain enzymes?
Yes. The current 40 and 50 fl oz concentrated-liquid page lists protease, amylase, and mannanase enzyme blends. Their presence does not by itself prove a head-to-head cleaning result.
Are both products EPA Safer Choice certified?
Yes, both current manufacturer pages display EPA Safer Choice certification. The label reflects EPA criteria for ingredients and other product attributes; it is not a guarantee of individual skin tolerance.
Is the Seventh Generation liquid 97% USDA Certified Biobased?
No. The current page for the 40 and 50 fl oz Concentrated Free & Clear liquid states 96%. EasyDose states 99%, and the laundry packs listed by the National Eczema Association state 94%.
Do both liquids have National Eczema Association recognition?
The current directory entry found for Seventh Generation applies to its laundry packs, not the concentrated liquid compared here. ECOS Free & Clear liquid is listed, but its directory and manufacturer ingredient lists currently differ, so verify the exact package.
Which detergent cleans better?
No neutral head-to-head test was supplied for these exact current liquids. Seventh Generation lists three enzyme blends and standard ECOS does not, but a fair performance verdict requires the same fabric, soil, dose, washer, cycle, and scoring method.
Which product costs less per load?
That depends on the exact size, retailer, sale price, machine type, and dose. Compare a dated price divided by the stated load count. Do not compare bottle price or ounces alone.
Which detergent does Freshly Folded provide?
Freshly Folded lists 7th Generation as one of five included detergent choices; ECOS is not on the listed menu. Confirm the exact stocked 7th Generation SKU, or ask before booking whether a non-stocked formula can be accommodated.
