Persil Free & Sensitive Ultra Concentrated Detergent

A high-performance liquid detergent utilizing a robust blend of anionic surfactants and a comprehensive quad-enzyme complex for deep stain removal, formulated without listed fragrances or dyes.

Performance Rating: 4.5

This formulation represents a premium heavy-duty detergent. It features a robust triple-surfactant system combining Anionics (LAS, SLES) and Non-ionics (Laureth-12) to tackle both particulate dirt and oily soils. The inclusion of a four-enzyme blend (Protease, Amylase, Mannanase, Cellulase) provides broad-spectrum stain removal capabilities against proteins, starches, and gums. Additionally, Polyethyleneimine alkoxylated is a high-performance polymer that effectively prevents dirt from resettling on clothes during the wash.

Safety Rating: 2.8

The safety rating is impacted by the presence of Boron compounds (MEA-borate, sodium metaborate), which are used as enzyme stabilizers but are flagged for potential reproductive toxicity. The formula also contains ethoxylated ingredients (SLES, Laureth-12), which carry a risk of 1,4-dioxane contamination, and Sodium C10-16 alkylbenzenesulfonate, which can be a skin irritant and is toxic to aquatic life in its raw form.

Final Rating: 3.9

This is a highly effective detergent designed for tough stains and general laundry needs. While it scores exceptionally well on cleaning performance due to its advanced chemistry (enzymes and polymers), the ingredient safety profile is lower due to the use of conventional chemicals like borates and synthetic sulfonates rather than milder, plant-based alternatives.

Verdict

This liquid laundry detergent represents a formulation engineered for maximum cleaning efficiency rather than gentle, natural care. The core of its cleaning power comes from a potent trio of surfactants: Sodium C10-16 alkylbenzenesulfonate, Sodium Laureth Sulfate (SLES), and Laureth-12. This combination ensures that both oily greases and particulate dirt are effectively lifted from fabrics and suspended in the wash water. While SLES is a standard industry workhorse for foaming and cleaning, it is worth noting that it can be drying or irritating to those with comprised skin barriers. The detergent’s standout feature is its sophisticated enzymatic profile. By including Protease, Amylase, Mannanase, and Cellulase, the formula is biologically active against a wide spectrum of stains. It acts as a molecular scissor, breaking down proteins (blood, sweat), starches (pasta sauces), and gums (processed food thickeners), while the Cellulase specifically targets damaged cotton fibers to reduce pilling and maintain fabric smoothness. Visually, the inclusion of Disodium distyrylbiphenyl disulfonate ensures that white fabrics remain crisp by counteracting yellowing through optical brightening. From a chemical safety and stability standpoint, the formula relies on borates to keep these enzymes active during storage. While effective, some consumers try to avoid boron compounds due to environmental or toxicity concerns, though they are present here in standard functional amounts. The use of Tetrasodium iminodisuccinate is a modern, more biodegradable choice for handling hard water compared to older chelating agents. Since the provided list lacks specific fragrance or dye components, this product appears to be an excellent candidate for those who need industrial-strength stain removal but wish to avoid the allergens associated with perfumes. It is a heavy-hitter suitable for family laundry, sports uniforms, and linens that require deep hygienic cleaning.
