Optical brighteners: properties and uses

Taking the varying properties into account when choosing an optical whitener is a sensible idea. Different industries have different specifications for optical brighteners. For example, thermoplastics that are molded prioritize heat stability and polymer compatibility. When applying textile fibers to textile applications, light fastness and desired shade may be taken into account. Optical brighteners should have the following properties:

  • Degree of whiteness levels
  • Wet fastness
  • Light fastness
  • Tints/shades
  • Temperature stability
  • Chemical stability

Health, Safety, and Regulations (Optical Brighteners)

Under Title 21, optical brighteners used in materials that come into contact with food, such as plastic and paper packaging, are regulated by the Food and Drug Administration (FDA). The Environmental Protection Agency (EPA) checks them when they are used for other things, such as cleaning.

What are the effects of optical brighteners on the environment?

The United States Environmental Protection Agency (EPA) in 1975 conducted a study on optical brighteners that raised doubts about their harmful effects on the environment and health. More than 29 million pounds of optical brighteners were produced. It’s likely that much more optical brighteners are being dumped into laundry detergents today than in 1969.

EPA’s Deforestation Free program is now inviting laundry developers to join forces with them so they can act as environmental representatives by making eco-friendly products. Manufacturers are encouraged to use optical brighteners that are “low toxicity to humans and the environment, both as parent chemicals and degradation by-products.”
