Dial Coconut Water & Mango Liquid Soap

A conventional, budget-friendly hand wash designed to offer deep cleansing and rich lathering while providing basic hydration through glycerin.

Performance Rating: 8.0

This hand wash achieves a strong 8.0/10 performance rating primarily due to its highly effective surfactant system. The combination of Sodium Laureth Sulfate (SLES) and Cocamidopropyl Betaine provides robust lathering and thorough dirt removal, while Cocamide MEA and Laureth-2 act as excellent thickeners and foam stabilizers. Additionally, Sodium Chloride helps optimize the product’s viscosity, and the humectant Glycerin helps retain moisture, ensuring the skin does not feel completely stripped after washing.

Safety Rating: 6.0

The safety rating is capped at 6.0/10 due to the presence of several potential skin irritants and sensitizers. Sodium Laureth Sulfate can strip the skin’s natural lipid barrier, leading to dryness. The inclusion of Ethanolamine and Cocamide MEA introduces risks of mild irritation and potential nitrosamine concerns. Furthermore, the formula contains generic Parfum along with known fragrance allergens including Limonene, Linalool, and Coumarin, which can trigger contact dermatitis in sensitive individuals.

Final Rating: 6.9

At 6.9/10 overall, this hand wash is a highly functional cleanser that balances excellent foaming and dirt removal with a moderate risk of skin irritation. While it performs reliably for general everyday use, the combination of harsh sulfates, Ethanolamine, and multiple fragrance allergens makes it less than ideal for those with dry, sensitive, or eczema-prone skin.

Verdict

This formulation is a classic example of a conventional, highly functional hand wash designed primarily to deliver deep cleansing and a satisfying, rich lather. At the core of its cleansing power is Sodium Laureth Sulfate (SLES), a highly effective surfactant. While SLES is generally considered milder and less stripping than its notorious cousin Sodium Lauryl Sulfate (SLS), it remains a strong degreaser. Over time and with frequent washing, SLES can strip the skin’s natural lipid barrier. To mitigate this drying potential, the formulators have paired it with Cocamidopropyl Betaine, a gentler co-surfactant that softens the overall cleansing action, and Glycerin, a reliable humectant that works to draw moisture back into the outer layers of the skin. The physical characteristics of the liquid—namely its viscosity and foaming stability—are managed by Cocamide MEA and Sodium Chloride (common table salt). These ingredients work in tandem to create a thick, gel-like consistency that feels substantial in the hand. Additionally, the formula features Trisodium Ethylenediamine Disuccinate, which is an excellent, eco-friendly chelating agent. This ingredient binds with minerals in tap water, ensuring that the hand wash lathers and cleanses effectively even in households with hard water. However, the formula falls short for those with delicate or reactive skin. The presence of Parfum (Fragrance) is joined by a trio of potential allergens: Limonene, Linalool, and Coumarin. While these molecules give the soap a pleasant and lingering scent, they are notorious culprits for triggering allergic contact dermatitis. The addition of Ethanolamine, which is typically used as a pH adjuster, and the synthetic dye CI 42090 (Blue 1) further increase the likelihood of irritation for sensitive individuals. In conclusion, this is a highly utilitarian, budget-friendly hand soap that gets the job done. It is incredibly efficient at removing grease, dirt, and daily grime. However, it lacks premium, skin-restoring lipids, botanical oils, or soothing agents. If you have normal skin and enjoy a richly scented, deeply cleansing wash, this product will serve you well. However, if your hands are prone to cracking, dryness, or eczema, you may want to seek out a milder, sulfate-free, and fragrance-free alternative to preserve your skin barrier.
