All Free & Clear is a fragrance-free, dye-free laundry detergent designed for sensitive skin. It uses the same basic surfactant system as conventional detergents but removes the two ingredient classes most responsible for contact reactions and undisclosed chemical exposure: synthetic fragrance and colorants. It is one of the most widely available sensitive-skin detergents and has long been recommended by dermatologists for eczema and fragrance sensitivity.
Tide Original contains synthetic fragrance (a complex undisclosed blend), optical brighteners that coat fabric fibers, and synthetic dyes. These ingredients are what make Tide smell and look the way it does — none of them clean clothing. Removing them, as All Free & Clear does, does not reduce cleaning performance.
The difference between these two detergents is primarily the absence of fragrance and dye in the Free & Clear version. Both use similar surfactant chemistry; both are reasonably effective cleaners. All Free & Clear rates 'better' because it eliminates the most common contact allergen categories in laundry detergent. Tide Original rates 'caution.' For any household with skin-sensitive individuals, children, or anyone sleeping in freshly washed sheets every night, the Free & Clear version is the more defensible choice.
