up&up Fragrance-Free Dish Soap

This conventional dish soap utilizes a powerful blend of surfactants and preservatives designed for heavy-duty grease removal and antimicrobial protection.

Performance Rating: 4.6

This formula utilizes a robust surfactant system combining Sodium Laureth Sulfate and Sodium Lauryl Sulfate, which are highly effective at emulsifying grease and oils. The inclusion of Lauramine Oxide significantly boosts foam stability, ensuring that the soap remains active throughout the dishwashing process. Sodium Xylenesulfonate acts as an efficient hydrotrope to keep the formula stable, while Sodium Chloride ensures a satisfyingly thick viscosity.

Safety Rating: 2.5

The primary safety concern stems from the preservatives Methylisothiazolinone and Methylchloroisothiazolinone, which are known skin allergens and sensitizers that can cause contact dermatitis in some users. Additionally, Sodium Lauryl Sulfate (SLS) is a well-documented skin irritant that may cause dryness or redness with frequent exposure, although its effects are somewhat mitigated by the presence of Sodium Laureth Sulfate.

Final Rating: 3.5

This is a top-tier performer when it comes to cutting through stubborn food residue and grease. It represents a standard, effective commercial dish soap. However, its environmental and skin safety profile is average at best, specifically due to the use of isothiazolinone preservatives and harsh sulfates. It is recommended for heavy-duty cleaning but may be unsuitable for those with sensitive skin or a preference for eco-friendly ingredients.

Verdict

This formulation is a classic example of a high-performance, mass-market cleaning agent designed for extreme utility in the kitchen. The inclusion of Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES) ensures that the soap produces a rich, stable lather capable of emulsifying stubborn fats and food residues almost instantly. These ingredients are industry standards for efficiency, though they are notoriously stripping to the skin’s natural moisture barrier due to their powerful degreasing properties. To further enhance cleaning power, Lauramine Oxide acts as a secondary surfactant and foam stabilizer, ensuring the bubbles last throughout the washing process even when faced with heavy oil loads. The inclusion of Sodium Xylenesulfonate acts as a hydrotrope, maintaining the clarity and consistency of the liquid across varying temperatures and preventing the formula from separating in the bottle. However, a significant point of concern for sensitive users is the specific preservative system used here. The combination of Methylisothiazolinone (MIT) and Methylchloroisothiazolinone (CMIT) is highly effective at preventing bacterial and fungal growth in water-based products, but these compounds are well-documented skin sensitizers. They are frequent culprits in cases of allergic contact dermatitis, particularly for those who wash dishes frequently without the protection of gloves. While the Citric Acid helps balance the pH and Sodium Chloride adjusts the viscosity for a satisfying pour, the overall profile remains chemically aggressive. For the average user, this product offers exceptional grease-cutting performance and great value. It handles burnt-on food and oily pots with ease. Yet, for individuals with eczema, psoriasis, or pre-existing skin sensitivities, the high concentration of sulfates and the presence of isothiazolinones may lead to significant redness, dryness, or painful irritation. It is a highly functional tool for a clean kitchen, but one that prioritizes cleansing efficacy and shelf stability over dermatological gentleness. Using it with protective rubber gloves is highly recommended for anyone prone to hand irritation or chronic dryness. Ultimately, it is a powerhouse cleaner that fulfills its primary purpose with clinical precision.
