Therapy Clean Dish Soap

This is a plant-enhanced, high-foaming dish soap formulated with a strong surfactant blend to effectively cut through tough grease while incorporating skin-conditioning glycerin.

Performance Rating: 8.1

The formula delivers strong cleaning efficacy driven primarily by Sodium Lauryl Sulfate, a potent anionic surfactant renowned for rapid grease-cutting ability and rich lather generation. To enhance washing efficiency, Caprylyl/Myristyl Glucoside and Cocamidopropyl Hydroxysultaine function as synergistic secondary surfactants, stabilizing foam and lifting diverse food residues even across varying water hardness levels. Meanwhile, Citric Acid helps optimize the pH environment for cleaning, and Sodium Chloride adjusts viscosity to ensure proper product cling on sponges and cookware. Together, these ingredients form a highly capable system that tackles everyday dish soils with ease.

Safety Rating: 7.4

The safety profile is generally positive and well-managed, supported by milder plant-derived co-surfactants like Caprylyl/Myristyl Glucoside and the addition of Glycerin to counteract skin dryness. Furthermore, Sodium Benzoate provides a relatively gentle preservation system with low toxicity concerns. However, the rating is restrained by Sodium Lauryl Sulfate, an ingredient with known potential for skin and eye irritation or barrier stripping during prolonged hand contact. Additionally, the inclusion of Natural Fragrance introduces potential contact allergens or sensitivities for delicate users, resulting in a sound yet moderately guarded safety evaluation.

Final Rating: 7.8

The overall evaluation reflects a successful balance between dependable cleaning power and a conscientious ingredient selection. By utilizing an effective primary degreaser supported by mild secondary surfactants and a hydrating humectant, the product achieves robust soil removal without relying on overly harsh preservative systems or harsh synthetic dyes. Although common concerns surrounding surfactant-induced dryness and fragrance allergens prevent a top-tier safety distinction, the thoughtful inclusion of supportive co-surfactants and skin-soothing components results in a reliable, well-rounded household dish soap suitable for everyday cleaning demands.

Verdict

The core cleansing system in this dish soap relies on a synergy between Sodium Lauryl Sulfate (SLS) and milder secondary surfactants, specifically Caprylyl/Myristyl Glucoside and Cocamidopropyl Hydroxysultaine. SLS delivers immediate, robust lathering and aggressive grease dissolution, while the glucoside and sultaine temper the harshness of the primary surfactant. This hybrid setup ensures the soap breaks down baked-on fats, heavy oils, and stubborn food residues quickly and effortlessly in both warm and cool water without requiring excessive scrubbing or repeated applications on cookware.

From a skin tolerability standpoint, this formulation strikes a respectable balance between cleaning power and dermatological care. Although SLS is traditionally known to strip natural skin lipids, the inclusion of Glycerin acts as a crucial humectant that helps retain hand moisture during routine dishwashing. Furthermore, the combination of mild amphoteric and non-ionic surfactants reduces overall irritation potential. However, individuals with heightened sensitivity should note the presence of Natural Fragrance, which can occasionally trigger contact allergies despite being naturally sourced.

Looking at the preservation and stabilization matrix, the product demonstrates a clean, thoughtful formulation strategy. It utilizes Sodium Benzoate alongside Citric Acid to maintain an optimal, slightly acidic pH that keeps microbial growth suppressed safely. This avoids harsh, sensitizing preservatives like methylisothiazolinone or parabens. Meanwhile, Sodium Chloride serves as a natural thickening agent to provide a smooth, easily dispensable viscosity that clings well to sponges without feeling overly watery or wasteful.

Overall, this dish soap delivers a dependable, high-performance wash that satisfies those looking for heavy-duty grease-cutting power with a cleaner ingredient profile. It successfully eliminates food residue, rinses clean without leaving filmy residues on glassware or ceramic plates, and avoids synthetic dyes and problematic biocides. While extremely sensitive users might prefer a sulfate-free and fragrance-free alternative, this soap is an outstanding everyday workhorse for busy households requiring uncompromising cleaning efficacy on stubborn cookware.

Who Should Avoid This Product?

Ingredient Evaluation

📁 Surfactants / 表面活性剂

🧪 Sodium Lauryl Sulfate / 十二烷基硫酸钠

Purpose: Acts as the primary anionic surfactant to cut through grease, lift food residues, and generate rich foam.

Concerns: Can cause skin dryness or irritation with prolonged or frequent direct contact.

Notes: Commonly plant-derived (from coconut or palm kernel oil) and prized for its strong degreasing power.

🧪 Caprylyl/Myristyl Glucoside / 辛基/肉豆蔻基葡糖苷

Purpose: Functions as a mild, plant-derived non-ionic co-surfactant to enhance cleansing and reduce overall formula harshness.

Notes: An alkyl polyglucoside made from plant sugars and fatty alcohols, offering excellent biodegradability.

🧪 Cocamidopropyl Hydroxysultaine / 椰油酰胺丙基羟磺基甜菜碱

Purpose: Acts as an amphoteric co-surfactant to boost and stabilize foam while mitigating surfactant irritation.

Concerns: Low risk of contact dermatitis in sensitive individuals, though generally milder than cocamidopropyl betaine.

Notes: Performs well across a wide pH range and maintains strong foaming performance even in hard water.

📁 Solvents & Humectants / 溶剂与保湿剂

🧪 Filtered Water / 过滤水

Purpose: Serves as the carrier and solvent that dissolves and stabilizes the other active ingredients.

Notes: Filtration removes minerals and impurities that could interfere with foaming performance and formula stability.

🧪 Glycerin / 甘油

Purpose: Functions as a humectant to help retain moisture and reduce skin dryness on hands during dishwashing.

Notes: Commonly vegetable-derived in plant-based home cleaning formulations.

📁 Preservatives & Stabilizers / 防腐剂与稳定剂

🧪 Sodium Benzoate / 苯甲酸钠

Purpose: Acts as a preservative to prevent microbial, yeast, and mold growth in the liquid formula.

Notes: Most effective in slightly acidic pH formulations, typically below pH 5.0.

🧪 Citric Acid / 柠檬酸

Purpose: Serves as a pH adjuster and buffer to maintain optimal formula acidity and support preservative efficacy.

Notes: Also exhibits weak chelating action that helps bind mineral ions in hard water.

🧪 Sodium Chloride / 氯化钠

Purpose: Functions as a natural viscosity adjuster to thicken surfactant solutions to an easy-to-dispense consistency.

Notes: Interacts with surfactant micelles to increase thickness without requiring synthetic polymer gums.

🧪 Natural Fragrance / 天然香精

Purpose: Provides a pleasant scent to neutralize base odor and enhance the user experience.

Concerns: May contain naturally occurring botanical allergens (such as limonene or linalool) for sensitive individuals.

Notes: Formulated from essential oils or botanical extracts rather than synthetic petrochemical aroma chemicals.
