Elevating fabric whiteness: Examining the enzymatic route in American laundry care

Laundry detergents help whiten clothes by removing stains and dirt that dull the fabric's appearance. Historically, detergents have used optical brighteners to deliver this benefit. Optical brighteners or fluorescent whitening agents are chemical compounds that absorb ultraviolet light and emit blue light, making whites appear brighter. However, it's important to note that not all laundry detergents are equally effective when it comes to whitening power.

This technical talk will explore an enzymatic approach for achieving whiteness results through consumer centric experimentation. Enzymes are naturally occurring proteins that act as catalysts to speed up chemical reactions. In the context of laundry detergents, enzymes are used to hydrolyze stubborn stains and soils from textiles. They are especially effective in improving whiteness in cotton textiles, one of the most widely used natural fibers in the world known for its softness, and plant-based origin.

Along with the considerations stated above, there has been an increasing desire for formulation freedom among detergent producers. Enzymes as whitening agents offer a unique advantage for formulators in overcoming various historical formulation constraints while strengthening the whiteness experience for consumers.
