The Short Answer
Seventh Generation Dish Soap is Acceptable, but proceed with Caution.
It is infinitely better than conventional blue soaps (like Dawn) because it strips out petroleum-based chemicals, synthetic dyes, and artificial fragrances. However, it stops short of being truly "clean." It relies on synthetic preservatives (MIT and BIT) that are well-documented skin irritants. If you have eczema, sensitive skin, or allergies, this soap may cause "dishpan hands" unless you wear gloves.
Why This Matters
Marketing claims like "Plant-Based" and "Free & Clear" often hide the full story. While Seventh Generation removes the most obvious toxins (like phthalates and formaldehyde-releasing agents), they swap in preservatives that help the product last longer on the shelf but can trigger contact dermatitis.
The Environmental Working Group (EWG) gives this product a C Rating. This middle-of-the-road score reflects a common issue in "green" cleaning: brands that are better for the environment (biodegradable) aren't always perfect for human health (skin irritation). Safest Dish Soap
What's Actually In Seventh Generation
Seventh Generation's formula is simple compared to conventional brands, but the end of the ingredient list is where the problems hide.
- Sodium Lauryl Sulfate (SLS) — The primary cleaning agent. It cuts grease effectively and is plant-derived (coconut/palm). While safe from cancer risks (unlike SLES, which can be contaminated with Is 1 4 Dioxane In Dishwasher Detergent), SLS is a known skin stripper that can cause dryness. Is Sls In Dish Soap Bad
- Methylisothiazolinone (MIT) — A synthetic preservative. It was named "Allergen of the Year" in 2013 due to skyrocketing rates of contact dermatitis. It is banned in leave-on cosmetics in Europe but allowed in rinse-off products like dish soap.
- Benzisothiazolinone (BIT) — A cousin to MIT, this preservative is also a skin sensitizer and an environmental pollutant toxic to aquatic life.
- Lauramine Oxide — A plant-based cleaning agent that boosts foaming. Generally considered safe but can be an irritant in high concentrations.
What to Look For
Green Flags:
- No Synthetic Fragrance — The "Free & Clear" version is truly unscented, avoiding phthalate-laden "parfum."
- Biodegradable — The formula breaks down safely in the environment (EPA Safer Choice Certified).
- No Dyes — Clear liquid means no coal-tar dyes or unnecessary colorants.
Red Flags:
- Isothiazolinones (MIT/BIT) — The biggest deal-breaker. If you see these long "zolinone" words, it's a risk for sensitive skin.
- SLS — While not "toxic," it is harsh. If you have dry hands, this will make them drier.
The Best Options
If you can find them, there are cleaner alternatives that skip the harsh preservatives entirely.
| Brand | Product | Verdict | Why |
|---|---|---|---|
| Attitude | Superleaves Dish Soap | ✅ | EWG Verified, uses colloidal oatmeal, no MIT/BIT. |
| Branch Basics | Concentrate | ✅ | Multi-purpose, completely preservative-free (must mix with water). |
| Seventh Generation | Free & Clear | ⚠️ | Good budget pick, but contains allergens (MIT/BIT). |
| Mrs. Meyer's | Dish Soap | 🚫 | Contains synthetic fragrance and harsh surfactants. |
| Dawn | Ultra | 🚫 | Petroleum-based, synthetic dyes, and 1,4-dioxane risks. |
The Bottom Line
1. Use it if you're on a budget. It is the best option available at standard grocery stores (Walmart/Target) compared to the toxic alternatives on the shelf next to it.
2. Wear gloves. Because of the SLS and synthetic preservatives, physical barriers are your best defense against irritation.
3. Upgrade if you can. For households with babies, eczema, or chemical sensitivities, switch to Attitude or Branch Basics to eliminate allergy risks entirely.
FAQ
Is Seventh Generation dish soap toxic?
No, it is not "toxic" in the sense of causing cancer or reproductive harm. However, it contains allergens (MIT/BIT) that can cause skin reactions. It is significantly safer than conventional brands but not the purest on the market.
Does Seventh Generation have 1,4-dioxane?
Likely not. They use SLS (Sodium Lauryl Sulfate), not SLES (Sodium Laureth Sulfate). SLES is the ingredient prone to 1,4-dioxane contamination. Seventh Generation also states they monitor for this contaminant. Is 1 4 Dioxane In Dishwasher Detergent
Is Seventh Generation better than Dawn?
Yes, absolutely. Dawn contains petroleum-derived surfactants, synthetic dyes (like Blue 1), and undefined "fragrance" mixtures. Seventh Generation uses plant-based cleaners and is fully biodegradable, making it safer for you and the planet. Dawn Vs Seventh Generation Dish Soap
