Seventh Generation has been a household name in “green cleaning” since 1988. Their products are in every Target, Whole Foods, and grocery store in the country. The branding is earthy, the messaging is environmental, and the name itself references an Iroquois philosophy about considering the impact of decisions on the next seven generations.
But in 2016, Seventh Generation was acquired by Unilever, one of the largest consumer goods conglomerates in the world. That raised eyebrows in the non-toxic community. And when you actually read their ingredient lists, you find a more complicated story than the green packaging suggests.
We went through their most popular product lines to give you a fair, ingredient-by-ingredient assessment.
The Short Answer
Seventh Generation is significantly better than conventional cleaning products from brands like Clorox, Lysol, and Mr. Clean. Their formulas use plant-derived surfactants, avoid the most harmful chemicals, and disclose ingredients more transparently than the industry standard. They’re a good step up from what most people are currently using.
But they’re not the cleanest option available. Several products contain ingredients that stricter non-toxic advocates would avoid, particularly in the fragrance and preservative categories. If you’re looking for the absolute cleanest cleaning products, brands like Branch Basics, Dr. Bronner’s, and ECOS score better on pure ingredient safety.
Ownership and What It Means
Seventh Generation was founded in Burlington, Vermont in 1988 as an independent green products company. In 2016, Unilever acquired them for an undisclosed amount estimated at $600-700 million.
Unilever also owns Dove, Axe, Domestos, and dozens of other conventional brands. The acquisition prompted concern that Seventh Generation’s formulations might be diluted to increase profit margins.
To Seventh Generation’s credit, their formulations have remained largely consistent post-acquisition. They continue to disclose ingredients transparently, and they’ve maintained or improved their third-party certifications. The concern is more about long-term direction than immediate changes.
Dr. Peter Attia, who frequently discusses reducing environmental toxin exposure, makes the practical point that corporate ownership doesn’t automatically change formulations, but it does change incentive structures. Monitoring ingredient lists over time matters more than reacting to ownership news.
Breaking Down Their Most Popular Products
Seventh Generation All-Purpose Cleaner (Free & Clear)
Ingredients: Water, sodium citrate, decyl glucoside, sodium carbonate, citric acid, calcium chloride, cymbopogon schoenanthus oil
This is one of their cleanest products. Let’s go through it.
- Decyl glucoside is a plant-derived surfactant. Well-tolerated, biodegradable, low irritation potential. EWG rates it favorably. This is the same surfactant used by genuinely clean brands.
- Sodium carbonate (washing soda) is a mineral-based cleaning agent. Effective and non-toxic.
- Sodium citrate is a buffering agent derived from citric acid. Safe.
- Citric acid adjusts pH. Naturally derived, no concerns.
- Cymbopogon schoenanthus oil is lemongrass oil. Used for mild fragrance and antimicrobial properties.
Verdict: This specific product is genuinely clean. The ingredient list is short, transparent, and uses well-established plant-based cleaners. If every Seventh Generation product looked like this, they’d earn a full recommendation.
Seventh Generation Dish Soap (Lavender Floral & Mint)
Ingredients: Water, sodium lauryl sulfate, lauramine oxide, decyl glucoside, sodium chloride, fragrance (with essential oils and botanical extracts), citric acid, calcium chloride, aloe barbadensis leaf juice, glycerin, methylisothiazolinone, zinc ricinoleate
Two ingredients stand out.
Sodium lauryl sulfate (SLS) is their primary surfactant. SLS is an effective cleaner but a known skin irritant. It’s not as concerning as sodium laureth sulfate (SLES), which can contain 1,4-dioxane, but it’s a step below the decyl glucoside they use in other products. If you wash dishes by hand without gloves, SLS will strip your skin’s natural oils.
Methylisothiazolinone (MIT) is the bigger concern. MIT is a preservative that has been flagged by the European Scientific Committee on Consumer Safety as a significant contact allergen. The EU restricted MIT in leave-on cosmetics in 2016 and has been tightening limits in rinse-off products. It’s still permitted in household cleaners in both the EU and U.S., but it’s one of the more concerning preservatives in common use.
Fragrance here includes essential oils and botanical extracts, which is better than undisclosed synthetic fragrance. But “fragrance” as a listed ingredient still means there’s a blend that’s not fully itemized on the label.
Verdict: Mixed. The SLS is an acceptable tradeoff for a dish soap (you need strong surfactants to cut grease), but the MIT and fragrance listing bring down the safety profile. If you have sensitive skin, wear gloves or switch to a dish soap without MIT, like Dr. Bronner’s.
Seventh Generation Laundry Detergent (Free & Clear)
Ingredients: Water, sodium citrate, sodium lauryl sulfate, lauramine oxide, glycerin, propanediol (from corn), protease enzyme, sodium carbonate, sodium polyaspartate, boric acid, calcium chloride, sodium hydroxide, citric acid
Boric acid stands out here. Boric acid is classified as a reproductive toxin in the EU (Category 1B under CLP regulation) and has been restricted in cosmetics. In cleaning products used in laundry machines (not applied directly to skin), the exposure route is different since residues on clothing after a full wash cycle are minimal. But it’s an ingredient that stricter non-toxic frameworks would flag.
SLS is present again. For laundry detergent, where the product is rinsed multiple times and not in direct skin contact, this is less concerning than in dish soap.
Verdict: The Free & Clear version avoids fragrance, which is the biggest improvement over conventional detergent. The boric acid is worth noting but the exposure through laundered clothing is low. This is a reasonable option, though brands like Molly’s Suds and Branch Basics avoid boric acid entirely.
Seventh Generation Disinfecting Multi-Surface Cleaner
Ingredients: Water, citric acid, sodium citrate, thymol (thyme oil), isopropanol, alkyl polyglucoside
Thymol is the active disinfecting ingredient. It’s derived from thyme essential oil and is EPA-registered as a disinfectant. This is one of the few plant-based ingredients that can make legitimate disinfecting claims, and Seventh Generation is one of the few brands using it instead of synthetic antimicrobials.
Isopropanol (isopropyl alcohol) is used as a solvent. It evaporates quickly and doesn’t leave residue.
Verdict: This is actually one of the better Seventh Generation products. Thymol-based disinfection is a genuinely effective, plant-derived alternative to bleach and quaternary ammonium compounds. If you need a disinfectant, this is one of the cleaner options available.
How Seventh Generation Rates on EWG
The Environmental Working Group’s Guide to Healthy Cleaning database gives Seventh Generation products mixed scores.
- All-Purpose Cleaner (Free & Clear): A rating. Excellent.
- Dish Soap (scented versions): B to C rating. MIT and fragrance are the issues.
- Laundry Detergent (Free & Clear): B rating. Good but not perfect.
- Disinfecting Cleaner: B rating.
For comparison, Branch Basics scores A across all categories, and Dr. Bronner’s Pure-Castile Soap scores A.
What Seventh Generation Gets Right
- Ingredient transparency is better than 90% of the cleaning industry. They list ingredients on labels and online.
- Plant-derived surfactants in most products. They’re not greenwashing the base cleaning agents.
- EPA Safer Choice certification on several products, meaning the EPA has reviewed each ingredient for safety.
- Thymol-based disinfection is a genuine innovation. Most “natural” disinfectants don’t actually work. Theirs does.
- B Corp certification reflects genuine corporate responsibility standards.
- Widely available. Having a reasonably clean product at every Target matters for accessibility.
Where They Fall Short
- Methylisothiazolinone in dish soap and some other products. This is the single biggest mark against them.
- SLS where milder surfactants would work. The Free & Clear all-purpose cleaner proves they can formulate without SLS. Why use it elsewhere?
- “Fragrance” as a listed ingredient, even when it includes essential oils. Full disclosure of every scent component would be the transparent approach.
- Boric acid in laundry detergent. Reproductive toxin classification in the EU is hard to ignore.
- Corporate ownership by Unilever creates long-term uncertainty about formulation direction.

Frequently Asked Questions
Is Seventh Generation safe for babies?
Their Free & Clear products (no fragrance, no dyes) are among the safer options at mainstream retailers. For the most sensitive applications (cloth diaper washing, nursery surfaces), genuinely fragrance-free and SLS-free products like Branch Basics or Dr. Bronner’s Baby Unscented are safer choices. See our non-toxic baby product guides for more.
Did Unilever change Seventh Generation’s formulas?
Formulations have remained largely consistent post-acquisition based on ingredient list comparisons. Some products have been added or discontinued, but the core lines use similar ingredients. Ongoing monitoring is warranted, as any acquisition creates pressure to optimize margins over time.
Is Seventh Generation better than Mrs. Meyer’s?
Overall, yes. Seventh Generation’s Free & Clear line avoids fragrance entirely, which is Mrs. Meyer’s biggest weakness. Both brands use MIT in some products. Seventh Generation has more EPA Safer Choice certified products and better EWG scores on average.
Can I trust the “plant-based” claims?
Seventh Generation’s surfactants are genuinely plant-derived. Decyl glucoside comes from coconut and corn. SLS can be derived from coconut oil (though the manufacturing process is intensive). “Plant-based” here is accurate, if imperfect. It doesn’t mean every ingredient is benign, but the cleaning agents are legitimately sourced from plants.
Should I switch from Seventh Generation to something cleaner?
If you’re currently using conventional cleaners (Clorox, Lysol, Mr. Clean), switching to Seventh Generation is a significant upgrade. If you’re already using Seventh Generation and want to go cleaner, Branch Basics or Dr. Bronner’s are the next step up. The Free & Clear line specifically is close to the top tier.
Is Seventh Generation’s disinfectant effective?
Yes. Thymol is EPA-registered as a disinfectant and has demonstrated efficacy against common household bacteria and viruses. It’s one of the few plant-derived disinfectants that can make legitimate, tested claims. Their disinfecting spray is one of the cleanest effective disinfectants you can buy at a regular store.
The Bottom Line
Seventh Generation occupies a middle ground. They’re meaningfully better than conventional cleaning products and dramatically more transparent about ingredients. Their Free & Clear line and their thymol-based disinfectant are genuinely good products that NonToxicLab can recommend.
But the methylisothiazolinone in their dish soap, the SLS in several formulas, and the occasional use of boric acid keep them from earning the top tier. If you’re shopping at Target and want the cleanest option on the shelf, Seventh Generation Free & Clear is usually the answer. If you’re willing to order online or shop at Whole Foods, Branch Basics and Dr. Bronner’s are cleaner across the board.
The best strategy: use Seventh Generation’s Free & Clear line for most cleaning tasks, and reach for their thymol disinfectant when you need actual disinfection. Skip the scented products entirely.
