But what if some of that brightness isn’t coming from cleaning at all?
Optical brighteners are ingredients added to many laundry detergents and fabric care products to make fabrics appear whiter, brighter, and less yellow.
They work by absorbing ultraviolet (UV) light and re-emitting it as blue light, helping fabrics appear brighter to the human eye.
In other words:
They change how we see the fabric.
Environmental organizations have raised concerns about their persistence in waterways, while some consumers prefer to avoid ingredients that remain on clothing, bedding, towels, and baby items after washing.

Did You Know
• Many white fabrics glow under ultraviolet (UV) light because of optical brighteners left behind during washing.
• A brighter-looking fabric is not necessarily a cleaner fabric.
• Over time, residues from laundry additives—including optical brighteners, fabric softeners, fragrances, and other coating agents, may build up on fibers, affecting the natural feel and performance of textiles. -
Cleaning Vs. The Feeling of Clean
• Optical brighteners create the look of clean.
