Member’s Mark Liquid Laundry Detergent, Fresh Scent

A high-performance, multi-enzyme liquid detergent designed for heavy-duty stain removal and fabric brightening.

Performance Rating: 4.4

This formulation represents a high-performance cleaning system. It utilizes a robust triple-surfactant blend (SLES, LAS, and Alcohol Ethoxylates) that effectively removes grease and oily soils. The addition of a multi-enzyme complex (Protease, Amylase, and Mannanase) ensures the breakdown of protein, starch, and gum-based stains. Furthermore, polyethyleneimine alkoxylated and sodium polyacrylate act as superior anti-redeposition agents, preventing loosened dirt from settling back onto fabrics.

Safety Rating: 2.5

The safety profile is significantly impacted by the presence of Methylisothiazolinone (MIT) and Methylchloroisothiazolinone (CMIT), which are known skin sensitizers and can cause allergic contact dermatitis. Additionally, the inclusion of Ethanolamine and Triethanolamine may cause respiratory or skin irritation. While effective, the chemical load includes optical brighteners and synthetic fragrances, which are often avoided by those with environmental or sensitivity concerns.

Final Rating: 3.5

Overall, this is a powerful detergent suitable for heavy-duty laundry needs and stubborn stains. Its performance is top-tier for a consumer product. However, its final score is tempered by a reliance on traditional, harsher preservatives and surfactants that may not be suitable for individuals with sensitive skin or those seeking eco-friendly alternatives.

Verdict

The provided ingredient list describes a highly effective, heavy-duty liquid laundry detergent formulated for broad-spectrum soil removal. The core cleaning action is driven by a powerful blend of anionic and non-ionic surfactants, specifically Sodium Laureth Sulfate (SLES) and Sodium C10-16 Alkylbenzenesulfonate (LAS). These agents excel at emulsifying oily residues and suspending particulates. The addition of C12-15 alcohols ethoxylated further enhances the detergent’s ability to tackle stubborn greasy stains, ensuring a thorough wash even in varying water temperatures. One of the standout features of this formulation is its triple-enzyme system, consisting of protease, amylase, and mannanase. Protease targets protein-based stains like grass or blood, while amylase breaks down starches, and mannanase addresses complex sugars found in food thickeners and gums. This makes the product particularly well-suited for families dealing with a variety of organic stains. Furthermore, the inclusion of polyethyleneimine alkoxylated serves as an advanced anti-redeposition agent, preventing loosened dirt from settling back onto fabrics during the wash cycle, which keeps clothes looking newer for longer. For aesthetic maintenance, the detergent utilizes Fluorescent Brightener 28, which deposits onto fibers to enhance the perception of whiteness and brightness under UV light. The presence of sodium citrate and tetrasodium iminodisuccinate acts as an eco-friendly chelating system, softening the water to improve surfactant efficiency. However, consumers should be aware of the preservative system. The combination of Methylisothiazolinone (MIT) and Methylchloroisothiazolinone (CMIT) is highly effective at preventing microbial growth but is a well-known trigger for contact dermatitis and allergic reactions in sensitive individuals. Additionally, the inclusion of fragrances and colorants contributes to the sensory experience but may be problematic for those with respiratory sensitivities or skin allergies. The presence of Ethanolamine and Triethanolamine helps manage pH levels but can be irritating to the eyes and skin if the concentrated product is handled improperly. Overall, this is a high-performance detergent built for maximum efficacy on tough stains, though it may be too harsh for those requiring a gentle or natural laundry solution. It represents a standard, robust commercial formula that prioritizes cleaning power and visual results over hypoallergenic properties.
