What Seventh Generation Dish Soap Lemongrass is made of, ingredients and materials
Seventh Generation Clementine Zest & Lemongrass uses plant-derived surfactants (typically coconut or corn-based) rather than petroleum-derived ones, paired with water and natural botanical extracts. Plant surfactants are biodegradable and generally pose lower aquatic toxicity than conventional detergents. The formula is free of synthetic dyes, synthetic fragrance allergens are avoided in favor of essential oil-based scents, and no PFAS are intentionally added. This composition reduces the chemical residue burden compared to conventional dish soaps.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Fragrance allergens (essential oils)
Clementine zest and lemongrass are natural fragrance compounds that can trigger contact dermatitis or respiratory sensitivity in a small subset of users, particularly those with citrus or botanicals sensitivities. Frequency is low relative to synthetic fragrance cocktails.
Eye and mucous membrane irritation
All surfactant-based soaps, including plant-derived formulas, can cause temporary eye irritation if splashed directly. This is an inherent property of surfactants and not specific to this brand, but is standard for the category.
Skin irritation from residual surfactants
Prolonged direct skin contact or inadequate rinsing can leave residual surfactant film, which may irritate sensitive or compromised skin. This risk applies to all dish soaps and is manageable with normal rinsing protocols.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Third-party PFAS-free verification
A third party reports verifying this product as PFAS-free.
No PFAS found in lab test
No PFAS detected in independent testing.
Formaldehyde / VOCs
Seventh Generation does not use formaldehyde-releasing preservatives or common allergen preservatives (methylisothiazolinone, etc.) in this product line based on public ingredient disclosures.

The brand's record and disclosure
Seventh Generation is a certified B Corp with a long public commitment to ingredient transparency and environmental safety. The brand discloses ingredient lists openly and holds third-party PFAS verification, which is less common in the detergent category. No major safety recalls, formulation controversies, or regulatory warnings are on record for this product. The brand's focus on plant-based chemistry and commitment to avoiding hazardous chemical classes aligns with its published standards.
How it compares in its category
Conventional dish soaps often contain synthetic surfactants, dyes, and fragrance compounds that carry higher allergen or bioaccumulation risk. Plant-based alternatives like this one typically score lower on acute toxicity and aquatic impact. Most major brands do not explicitly verify PFAS-free status, making Seventh Generation's third-party assurance a material differentiator. Price is typically 20-40% higher than mass-market brands, reflecting the use of more costly plant-derived inputs.
If you buy it
Use as directed on the bottle, typically 1-2 teaspoons per sink or dishwasher load. Store in a cool, dry place away from direct sunlight to preserve scent integrity and prevent separation. The formula is low concern for septic systems and is fully biodegradable. No special precautions are needed beyond standard hand-washing practice and eye contact avoidance.
