Dealworthy Liquid Dish Soap

A conventional, high-foaming dish soap formulated with proven grease-cutting surfactants alongside synthetic preservatives and artificial additives for basic everyday dishwashing.

Performance Rating: 7.7

The formula delivers solid cleaning capability largely driven by sodium laureth sulfate, a primary anionic surfactant renowned for its strong grease-cutting power and rich lathering capacity. Working alongside it, lauramine oxide acts as an effective secondary surfactant and foam booster, enhancing the breakdown of stubborn food residues and stabilizing suds during washing. Sodium chloride serves as a thickening agent, ensuring the liquid maintains an optimal viscosity for controlled dispensing. While highly capable for standard kitchen messes, the absence of advanced enzymes or chelating agents keeps its efficacy at a reliable, everyday level.

Safety Rating: 5.2

The safety profile is noticeably compromised by several harsh and sensitizing ingredients. Most prominently, the preservative blend of methylisothiazolinone and methylchloroisothiazolinone poses substantial risks for contact allergy, skin sensitization, and dermatitis, especially during frequent hand washing. Furthermore, sodium laureth sulfate can strip natural skin oils, causing dryness or mild irritation over time. The inclusion of unspecified fragrance and artificial colorants introduces additional potential allergens and respiratory triggers, making the formulation less ideal for sensitive skin and prolonged, unprotected exposure.

Final Rating: 6.6

The overall assessment reflects a standard household dish soap that balances dependable cleaning efficacy against moderate dermatological drawbacks. Its surfactant core ensures dependable grease removal and sudsing for routine dishwashing tasks. However, the reliance on isothiazolinone preservatives and synthetic additives reduces its appeal regarding skin compatibility and gentle formulation. Consequently, the product serves as a capable, utility-grade dish detergent that performs well at the sink, though individuals with sensitive skin would benefit from wearing protective gloves during extended use.

Verdict

This dish soap relies on a classic surfactant system centered around sodium laureth sulfate (SLES) and lauramine oxide. SLES is a reliable anionic surfactant widely recognized for its robust foaming capabilities and strong ability to lift tough oils and food residues from cookware and plates. Lauramine oxide acts as a supportive secondary surfactant and foam stabilizer, boosting grease cutting while helping maintain a rich, long-lasting lather even in hard water conditions. Together with sodium chloride acting as an effective thickening agent, the primary cleaning foundation provides powerful degreasing performance suitable for standard household dishwashing chores.

While the cleansing efficacy is strong, the preservative system presents notable drawbacks for sensitive users. The formula incorporates a combination of methylisothiazolinone (MI) and methylchloroisothiazolinone (MCI), broad-spectrum antimicrobial agents that effectively prevent bacterial growth. However, this isothiazolinone blend is recognized by dermatologists as a potent contact allergen that can provoke allergic contact dermatitis, redness, and itching, particularly with frequent, direct hand exposure. Although wash-off products carry lower exposure risks than leave-on cosmetics, individuals washing dishes without protective gloves may experience heightened skin irritation over prolonged daily use.

The addition of synthetic fragrance and artificial colorants enhances the overall sensory experience by delivering an appealing scent and bright visual appearance. Nevertheless, these aesthetic additives contribute little to actual cleaning performance while introducing further potential triggers for individuals prone to respiratory sensitivities or fragrance allergies. Furthermore, because SLES is an aggressive degreaser, it can strip natural skin oils from hands along with food grease. As a result, frequent hand dishwashing without post-wash moisturizing or rubber gloves can leave skin feeling noticeably dry, tight, or stripped.

Overall, this product serves as a cost-effective, heavy-duty dishwashing detergent that excels at lifting stubborn grease and producing voluminous suds. It performs reliably on greasy pots, pans, and everyday glassware, delivering the rapid grease breakdown that consumers expect from traditional commercial formulas. However, due to the presence of potent preservatives, artificial dyes, and strong surfactants, it is not well-suited for households seeking gentle, eco-conscious, or hypoallergenic formulations. For optimal safety and comfort, users are advised to pair this soap with protective gloves to mitigate dryness and potential sensitization.

Ingredient Evaluation

📁 Surfactants / 表面活性剂

🧪 Water / 水

Purpose: Acts as a solvent and liquid carrier for the surfactant system and other active ingredients.

Notes: Forms the base of the formulation, typically comprising 60% to 85% of liquid dish soaps.

🧪 Sodium Laureth Sulfate / 月桂醇聚醚硫酸酯钠

Purpose: Functions as the primary anionic surfactant for grease removal and foaming.

Concerns: May cause skin dryness or irritation upon prolonged contact; can contain trace 1,4-dioxane impurities from ethoxylation.

Notes: Milder and less drying to skin than sodium lauryl sulfate (SLS), and thickens efficiently with salt.

🧪 Lauramine Oxide / 月桂胺氧化物

Purpose: Acts as a secondary surfactant, foam booster, and grease-cutting booster.

Notes: Provides synergistic cleaning with anionic surfactants and maintains foam stability even in hard water or greasy conditions.

🧪 Sodium Chloride / 氯化钠

Purpose: Functions as a viscosity builder and thickening agent.

Notes: Works by screening electrostatic repulsion between anionic surfactant micelles, promoting micellar growth and increasing formulation thickness.

📁 Preservatives / 防腐剂

🧪 Methylchloroisothiazolinone / 甲基氯异噻唑啉酮

Purpose: Provides broad-spectrum antimicrobial protection against bacteria, yeast, and mold.

Concerns: Strong skin sensitizer and contact allergen with potential to trigger contact dermatitis.

Notes: Frequently paired with methylisothiazolinone in a 3:1 ratio (known commercially as Kathon CG) and restricted to parts-per-million levels in rinse-off products.

🧪 Methylisothiazolinone / 甲基异噻唑啉酮

Purpose: Prevents bacterial and microbial spoilage during product storage and use.

Concerns: Well-known skin sensitizer and allergen associated with allergic contact dermatitis.

Notes: Strictly regulated globally; largely banned in leave-on cosmetics but permitted at very low concentrations in rinse-off formulations.

📁 Fragrance / 香精与添加剂

🧪 Fragrance / 香精

Purpose: Imparts a pleasant scent and masks raw chemical odors.
