There's a hidden reason why most laundry detergents are blue, and it has nothing to do with cleaning power
Blue laundry detergents use optical brighteners to make clothes appear brighter. These compounds absorb ultraviolet light and emit blue light, neutralizing yellow tones. Psychologically, blue is associated with cleanliness, freshness, and trust by consumers. Other detergent colours signify different product features like eco-friendliness or premium quality. Actual cleaning effectiveness relies on ingredients like surfactants and enzymes.
