Seventh Generation Dish Soap - Free & Clear

This is a highly effective, high-foaming dish soap formulated with strong surfactants, a skin-conditioning agent, and synthetic preservatives to deliver a powerful grease-cutting performance.

Performance Rating: 8.6

This formula achieves a high 8.6/10 performance rating thanks to its highly effective surfactant system. Sodium lauryl sulfate (SLS) provides exceptional grease-cutting power and rich foam, which is further stabilized and boosted by lauramine oxide. The addition of decyl glucoside offers mild yet effective secondary cleaning, while magnesium chloride acts as a viscosity builder to improve texture and performance. Furthermore, citric acid serves as a chelating agent to help the soap cut through grime even in hard water conditions.

Safety Rating: 5.4

The moderate 5.4/10 safety rating is primarily due to several known skin irritants and sensitizers. Sodium lauryl sulfate (SLS) is widely recognized as a skin irritant that can cause dryness and strip natural oils. More significantly, the formulation contains methylisothiazolinone (MIT) and benzisothiazolinone (BIT), both of which are potent synthetic preservatives associated with skin sensitization, allergic contact dermatitis, and environmental toxicity.

Final Rating: 6.9

With a 6.9/10 final rating, this dish soap is a powerful cleaner that comes with notable skin irritation risks. It delivers strong degreasing capabilities and impressive suds due to its robust surfactant blend of SLS and lauramine oxide. However, the formulation is held back by safety concerns surrounding SLS irritation and the use of sensitizing preservatives like methylisothiazolinone (MIT) and benzisothiazolinone (BIT), making it less ideal for those with sensitive skin.

Verdict

This dish soap formulation strikes a balance between heavy-duty grease cutting and gentle skin conditioning, making it a highly practical option for everyday household cleaning. At its core, the formula relies on sodium lauryl sulfate (SLS), a powerhouse anionic surfactant known for its exceptional ability to break down stubborn grease, oils, and baked-on food residues. To enhance this cleaning prowess, it is paired with lauramine oxide, which acts as a foam stabilizer and booster, ensuring the soap produces a rich, long-lasting lather that remains active throughout the dishwashing process. To mitigate the stripping and drying effects naturally associated with strong surfactants like SLS, the formula incorporates decyl glucoside, an ultra-mild, plant-derived non-ionic surfactant, alongside glycerin, a well-known humectant. Glycerin draws moisture to the skin, helping to protect your hands from becoming excessively dry or irritated during prolonged dishwashing sessions. Additionally, citric acid is used to balance the pH, ensuring the formula remains gentle on the skin barrier, while magnesium chloride serves to optimize the product’s viscosity for a pleasant, easy-to-dispense texture. However, a notable drawback lies in the choice of preservatives. The formula uses a combination of benzisothiazolinone (BIT) and methylisothiazolinone (MIT) to prevent microbial contamination and extend shelf life. While highly effective at keeping the product shelf-stable, MIT is a well-documented contact allergen and sensitizer. Even though this is a rinse-off product, individuals with pre-existing skin conditions, such as eczema, psoriasis, or contact dermatitis, may experience irritation, redness, or allergic reactions upon contact. In conclusion, this dish soap is an excellent performer for those prioritizing sheer grease-cutting power, a rich lather, and a cost-effective clean. It effectively tackles tough messes while offering some hand-moisturizing benefits. However, if you have highly sensitive skin or a known allergy to isothiazolinone preservatives, you may want to seek out a milder, preservative-free, or hypoallergenic alternative to avoid potential hand irritation.
