Tide Ultra OXI Boost High Efficiency Liquid Laundry Detergent

This is a high-performance, heavy-duty liquid laundry detergent engineered with a multi-surfactant cleaning system and an advanced four-enzyme cocktail to tackle stubborn stains, odors, and fabric dullness.

Performance Rating: 9.6

The formula demonstrates an exceptionally high cleaning standard driven by a comprehensive multi-surfactant system, combining anionic alkylbenzenesulfonates, nonionic alkeths, sulfates, and amine oxides for superior grease and particulate removal. This is reinforced by a quad-enzyme cocktail containing subtilisin, amylase, cellulase, and mannanase, which thoroughly degrades protein, starch, and complex food stains while smoothing cotton fibers. Furthermore, alkoxylated polyethyleneimines provide excellent anti-redeposition and soil-suspending power, while chelating builders like tetrasodium glutamate diacetate and citrate neutralize mineral interference in hard water. Fabric-shading chromophores also contribute to noticeable whitening and fabric brightening.

Safety Rating: 7.1

The safety evaluation reflects a moderate profile typical of concentrated cleaning formulations. Key concerns stem from potent anionic surfactants such as sodium lauryl sulfate and linear alkylbenzene sulfonates, which alongside ethanolamine, present known skin and ocular irritation potential upon direct contact. The inclusion of active enzymes and unspecified fragrances introduces risks of contact allergy and respiratory sensitization for susceptible users. Additionally, benzisothiazolinone serves as an effective preservative but is a recognized skin sensitizer. However, the presence of readily biodegradable chelants like tetrasodium glutamate diacetate helps mitigate the overall environmental and toxicological burden.

Final Rating: 8.7

The overall assessment reflects a high-tier product that successfully prioritizes heavy-duty stain removal while maintaining an acceptable domestic safety standard. Its performance is near the pinnacle of modern laundry chemistry, leveraging a robust enzymatic matrix, advanced polymers, and diverse surfactants to handle complex, deep-set soils across various wash conditions. While the concentration of irritating surfactants, fragrances, and isothiazolinone preservatives tempers the safety score, these elements are standard and managed within normal diluted wash use. Ultimately, the formula offers industry-leading cleaning efficiency balanced with a thoroughly vetted consumer safety margin.

Verdict

This liquid detergent features an exceptionally potent surfactant system designed for maximum stain lifting and degreasing efficiency. The synergistic combination of anionic surfactants like Sodium and MEA C10-16 Alkylbenzenesulfonate, Sodium Lauryl Sulfate, and MEA Laureth Sulfate works alongside nonionic C10-16 Alketh to penetrate deep into fabric weaves. Together with C10-16 Alkyldimethylamine Oxide and fatty acid soaps, this formulation effortlessly emulsifies body oils, food grease, and everyday grime. The presence of citrate and chelating builders ensures the surfactants perform optimally even in challenging hard water conditions.

The stain-fighting capabilities are substantially elevated by a comprehensive quadruple-enzyme matrix. It incorporates Subtilisin (protease) to digest blood, sweat, and protein-based soils, Amylase to dissolve sticky carbohydrate residues, and Mannanase to remove tough food stabilizers and sauces. Meanwhile, Cellulase smooths frayed microfibers, helping to eliminate fuzz and pilling while rejuvenating faded colors. Coupled with alkoxylated polyethyleneimines, which trap loosened soils and stop them from redepositing onto clean garments, this detergent delivers remarkable stain eradication and long-term fabric clarity.

Fabric aesthetics and machine performance are further optimized through specialized additives and fabric care agents. The inclusion of cyan and violet polyoxyalkylene chromophores provides an optical brightening effect, counteracting fabric yellowing to keep whites radiant without damaging delicate fibers. Foam generation in high-efficiency washing machines is meticulously managed by a silicone-based defoaming complex, including Simethicone, Dimethicone, and Trimethylsiloxysilicate. Additionally, Tetrasodium Glutamate Diacetate provides an eco-friendly chelating boost that prevents mineral scale buildup on both garments and washer drums.

Despite its superior cleaning efficacy, this formulation may present drawbacks for individuals with delicate skin. The inclusion of synthetic fragrances and the preservative Benzisothiazolinone (BIT) represents a known trigger for contact dermatitis, allergic eczema, and respiratory sensitivities. Furthermore, the high concentration of aggressive anionic detergents like Sodium Lauryl Sulfate can leave trace residues on clothing if not thoroughly rinsed. As a result, while it excels as a heavy-duty household cleaner, it is less suited for washing infant garments or clothes for people with severe dermatological conditions.
