Overview
- Coverage on Thursday, June 18, 2026, reiterated that bio detergents include enzymes that break down proteins, fats and starches so stains like grease, blood and food lift more easily in cool washes.
- Those enzymes work by chemically cutting stain molecules into smaller pieces that surfactants can wash away, which is why bio formulas often outperform non‑bio on stubborn marks at lower temperatures.
- Non‑bio detergents lack these enzymes and rely on surfactants and traditional cleaners, making them gentler on skin but less effective on tough stains unless you pre‑treat or use hotter washes.
- People with eczema, allergies or very sensitive skin are advised to choose non‑bio for baby clothes and delicates because enzymes can sometimes trigger irritation.
- Many households keep both types and select by use case—bio for sportswear and heavily soiled items, non‑bio for delicates—and shoppers should match detergent choice to fabric, typical stains and any skin sensitivity.
