A conventional, heavy-duty dish soap formulated with powerful surfactants like sodium laureth sulfate and sodium lauryl sulfate to aggressively cut through stubborn grease and grime, though it contains strong preservatives that may trigger skin sensitivities.
The high rating is driven by an exceptionally strong surfactant system. The combination of sodium laureth sulfate (SLES) and sodium lauryl sulfate (SLS) delivers outstanding grease-cutting performance and rich lather. This is further enhanced by lauramine oxide, which acts as an excellent foam booster and stabilizer. Additionally, sodium xylenesulfonate serves as a hydrotrope to maintain formula stability, and sodium chloride effectively builds the viscosity, ensuring a thick, premium-feeling texture that clings to dishes for efficient cleaning.
The low safety rating is primarily due to the inclusion of methylisothiazolinone (MIT) and methylchloroisothiazolinone (MCI), which are notorious skin sensitizers and contact allergens capable of triggering dermatitis. Furthermore, sodium lauryl sulfate (SLS) is a well-known skin irritant that can strip skin of its natural moisture barrier. There are also safety concerns regarding sodium laureth sulfate (SLES), which can be contaminated with 1,4-dioxane, a suspected carcinogen, during the ethoxylation process.
The final rating reflects a product that offers excellent cleaning efficiency but carries significant skin irritation and allergy risks. While the formula is highly effective at cutting through tough grease thanks to powerful surfactants, the presence of harsh ingredients like SLS and strong preservatives like MIT/MCI compromises its safety profile, making it less suitable for users with sensitive skin.
This conventional dish soap formulation is built around a highly effective combination of anionic and amphoteric surfactants, specifically sodium laureth sulfate (SLES), sodium lauryl sulfate (SLS), and lauramine oxide. Together, these powerful ingredients work synergistically to create a rich, dense, and long-lasting lather that excels at lifting, breaking down, and emulsifying stubborn grease, heavy oils, and dried-on food particles from cookware, plates, and cutlery. SLES offers robust cleansing with slightly less irritation potential than its cousin SLS, while lauramine oxide acts as an excellent foam booster and stabilizer, ensuring the soap remains active and bubbly even in highly soiled water. To maintain structural integrity and user experience, sodium xylenesulfonate and sodium chloride (common table salt) are incorporated into the formula; they function as viscosity modifiers to ensure the product has a satisfyingly thick, slow-pouring texture and remains chemically stable over shelf life. Lastly, citric acid is included as a pH adjuster to balance the formulation, bringing it closer to a skin-compatible level. However, from a dermatological perspective, this formulation is incredibly stripping to the skin. The sheer cleansing strength of SLS and SLES means that they do not just strip grease off your plates; they also aggressively deplete the skin’s natural lipid barrier, leading to dryness, redness, tightness, and potential irritation after washing. More concerning is the choice of preservation system. This formula relies on methylchloroisothiazolinone (CMIT) and methylisothiazolinone (MIT). These isothiazolinone preservatives are notorious contact allergens and strong sensitizers. While they are incredibly effective at preventing bacterial, yeast, and fungal contamination in water-heavy products, they are also a frequent culprit behind allergic contact dermatitis, eczema flare-ups, and severe skin irritation. For individuals who wash dishes multiple times a day bare-handed, prolonged exposure to these ingredients carries a high risk of sensitization over time. In summary, this is a highly functional and exceptionally efficient grease-cutting agent that will easily handle your heaviest kitchen messes at a very affordable price. However, its reliance on harsh surfactants and highly sensitizing preservatives means it is far from gentle on human skin. If you choose to use this product, it is strongly recommended that you wear protective rubber gloves to shield your hands, or alternatively, seek out a milder, sulfate-free, and isothiazolinone-free formula if you have sensitive skin, eczema, or prefer washing dishes with your bare hands.
🧪 water / 水
Purpose: Acts as a solvent and a carrier for all other ingredients.
Concerns: None.
Notes: Forms the base of the liquid dish soap formula to control viscosity and dilute active ingredients to safe levels.
🧪 sodium laureth sulfate / 月桂醇聚醚硫酸酯钠
Purpose: Anionic surfactant used for cleansing and creating rich foam.
Concerns: Can cause mild skin irritation. There is a potential risk of 1,4-dioxane contamination during the manufacturing process.
Notes: Generally milder on the skin compared to sodium lauryl sulfate due to the ethoxylation process.
🧪 sodium lauryl sulfate / 月桂醇硫酸酯钠
Purpose: Anionic surfactant used for excellent grease removal and heavy foaming.
Concerns: Known to be a skin irritant, especially with prolonged exposure, and can strip natural oils from hands.
Notes: Widely used for its powerful cleaning efficacy but is harsher than sodium laureth sulfate.
🧪 lauramine oxide / 月桂基氧化胺
Purpose: Amphoteric/non-ionic surfactant used as a foam stabilizer and booster.
Concerns: Can cause mild skin and eye irritation, but is generally considered to have low toxicity.
Notes: Helps maintain a stable lather while assisting in cutting grease and enhancing the mildness of the formulation.
🧪 sodium xylenesulfonate / 二甲苯磺酸钠
Purpose: Hydrotrope and solubilizer used to keep the formula clear and uniform.
Concerns: May cause mild skin or eye irritation in concentrated forms.
Notes: Prevents the separation of ingredients in the liquid and modifies viscosity to keep it pourable.
🧪 sodium chloride / 氯化钠
Purpose: Viscosity builder (thickener).
Concerns: Non-toxic, but high concentrations in soap can contribute to dry skin.
Notes: Common table salt; works synergistically with anionic surfactants like sodium laureth sulfate to thicken the dish soap.
🧪 citric acid / 柠檬酸
Purpose: pH adjuster and chelating agent.
Concerns: Safe at standard concentrations, but can be a mild irritant in pure form.
Notes: Used to balance the acidity of the dish soap to ensure it is skin-compatible and to optimize preservative effectiveness.
🧪 methylisothiazolinone / 甲基异噻唑啉酮
Purpose: Preservative to prevent microbial and bacterial growth.
Concerns: A strong skin sensitizer and common allergen that can trigger contact dermatitis.
Notes: Often restricted in leave-on cosmetic products, but commonly used in rinse-off household products like dish soap.
🧪 methylchloroisothiazolinone / 甲基氯异噻唑啉酮
Purpose: Preservative to prevent the growth of bacteria, yeast, and fungi.
Concerns: A known allergen and contact sensitizer, similar to methylisothiazolinone, and can cause skin irritation.
Notes: Typically used in combination with methylisothiazolinone (commonly known as Kathon CG) in very low concentrations.
