Optical Brightening Agent are chemical compounds that absorb light in the ultraviolet and violet region (usually 340-370 nm) of the electromagnetic spectrum, and re-emit light in the blue region (typically 420-470 nm) by fluorescence. Fluorescent emission is a short-lived period of light emission by a fluorophore, unlike phosphorescence, which is long-lived. These additives are often used to enhance the appearance of color of fabric and paper, causing a "whitening" effect; they make intrinsically yellow/orange materials look less so, by compensating the deficit in blue and purple light reflected by the material, with the blue and purple optical emission of the fluorophore.

Features :
Optical Brightening Agent (OBA) or Fluorescent whitening agent (FWA) is a chemical that absorbs energy in the UV energy from the electromagnetic spectrum and when interact with the chemical, it re-emits this energy in the blue region. The blue reflection spike is dependent on the dosage of the OBA or FWA. OBA is used to create whitening effect, thus making white looks whiter and is a cost-effective method to enhance the whiteness of detergent
Features :
Numerous materials especially textiles, both classical Cotton, wool, linen and silk and synthetic mainly polyamide, polyester and polyacrylonitrile , are not completely white and efforts have been made since ancient times to free from their yellowish tinges. Bleaching in the sun, bluing and later chemical bleaching of textile and other materials increased the brightness of the products and eliminated to a certain extent the yellowish tinge to greyish yellow hue or the local impurity of the original or industrially treated material.
When Optical brighteners first came up they were regarded as bleaching auxiliaries, which enabled a shorter or a milder bleach when used in very small quantities Approximately 0.001 to 0.05% . They were also called as Optical Bleaching Agents. Cotton and linen bleachers knew 200 years ago the effect of bleaching could be improved with the help of horse chestnut extracts. This is due to the fact the inner bark of the horse chestnut contains aesculin or esculinic acid, a glucoside which is a derivative of coumarin and which has ultra violet fluorescence. Scientist recommended aesculin for improving the whiteness on the basis of theoretical considerations. An aqueous solution of aesculin proved more suitable, but had two major draw backs. Firstly it was not fast to washing and secondly aesculin on the fiber was very sensitive to light. Then came the introduction of organic products based on Diaminostilbine sulphonic acid derivatives.
