Learn All About Optical Brighteners: A Full Guide

You guys knew that plastic has hidden magic energies, right? I am sure you have also noticed how some plastic looks much brighter and whiter than others. This is done by using a special ingredient, optical brighteners (OB), which are the secret for just about all laundry detergents on the market. These additives improve the look of plastics, making them stand out and attractive. But what, pray tell, are optical brighteners? Read on in this complete overview to learn all about what these crucial compounds do for plants.

Optical Brighteners

Optical brighteners (fluorescent whitening agents) are chemical compounds that absorb ultraviolet light and reemit it as visible blue light. This causes the material to appear brighter and whiter. Optical brighteners are predominantly used in textiles, but optical brighteners for plastics are gradually entering the list due to their various qualities and capabilities that add beauty and performance to the appearance of different plastic products.

What Optical Brighteners Do

They do this by transforming UV light into viewable blue light and causing plastic to lose the yellowish tint that can develop over time. This is the process where emitting light appears whiter, which properly looks good visually for the product. Here’s how it happens:

• Filtering of Ultraviolet Light: Invisible to the human eye, OBs absorb UV light.
• Light is reemitted. This light emerges as visible blue light.
• Boosts Color: The blue light will inactivate and get rid of all the yellowness inside your teeth to make them look brighter and whiter.

What makes optical brighteners useful for plastics?

Optical brighteners are essential for improving the aesthetic and quality of plastic goods. Here’s why they’re used:

• Improved Aesthetics: OBs make plastics brighter and whiter, which is more visually appealing to customers.
• Repeatability of color: standardizes the color of plastic products from one production batch to another.
• UV Protection: Certain optical brighteners can deliver added UV protection for the plastic product, keeping it in good standing over time.

Optical Brighteners Different Times of Optical Brighteners

There are different kinds of optical brighteners differentiated by their applications. Here’s a quick overview:

• Stilbene Derivatives: The most popular, perfect for use in the brightening of plastics.
• Coumarins: utilized in plastics, renowned for their high fluorescence
• Naphthalimides: These are used for certain plastics and have better stability characteristics.
• Benzoxazoles combine heat resistance and are thus used for plastics subjected to high temperatures.
