Optical brighteners, also known as fluorescent whitening agents (FWAs) or optical brightening agents (OBAs), are chemical compounds used in various industries, primarily in textiles, paper, and detergents. These substances absorb ultraviolet (UV) light and re-emit it as visible blue light, making colors and whites appear brighter and more vivid. Optical brighteners are often added to laundry detergents to give the illusion of cleaner and whiter clothing by enhancing their visual brightness. They are also used in the paper industry to improve the brightness and whiteness of paper products. Optical brighteners' ability to improve the appearance of materials under certain lighting conditions makes them valuable in enhancing the visual quality of a wide range of consumer and industrial products.

Titanium dioxide. Titanium dioxide, also called titania, (TiO2), is a white, opaque, naturally occurring mineral existing in a number of crystalline forms, the most important of which are rutile and anataseâ?¦ Titanium dioxide was one of the first materials to be used in nanotechnology products Titanium Dioxide, probably the most widely used nanomaterial is a white, opaque, naturally occurring mineral existing in a number of crystalline forms, the most important of which are rutile and anatase. Titanium Dioxide is odorless and absorbent. Its most important function in powder form is as a widely used pigment for leading whiteness and opacity. Uses and Application- Titanium Dioxide provides opacity & durability, to ensure the longevity of the paint & protection of the paint surface. It helps to minimize the bitterness, fading, and cracking that occurs in plastics and other materials as a result of light exposure. It is used in cosmetics to aid in hiding blemishes and brightening the skin. It is used in the paper industry to make it more white, bright, and opaque. The opacity to visible and ultraviolet light offered by Titanium Dioxide protects food, beverages, supplements, and pharmaceuticals from pre-mature degradation, enhancing the longevity of the product. It is also used in drug tablets, capsule coatings, and as a decorative aid in some foods
