  2. Optical brightener (OB) and Optical Brightener -1(OB-1) are brightening agents often confused with each other. Both are used for brightening but on different types of materials. Therefore, it is essential to understand the details and differences between them before selecting.

  3. What is Optical Brightener(OB)? Optical Brighteners have a wide range of applications; fabric whitening is one. Materials such as plastics have a certain level of yellowness that gives them a dull finish. To add brightness to the material, OB is added to the plastics. A similar application takes place for the fabric. Other colorants are used along with the Optical Brightener to derive the required color and shade in the materials. Optical Brighteners are easily used in plastics as they have a high melting point which helps them easily mix with the molten plastic.

  4. What is OB1? OB1 has a similar effect but with different chemical formulas and applications. It is also used in textiles and plastics to increase the whiteness of the product. The final whiteness derived using OB 1 has a light reddish-blue effect. What Product Uses Optical Brightener OB, Which Product Is More Suitable For Optical Brightener OB-1? One of the main differentiators can be the products on which OB and OB1 can be used. This is decided based on the melting point. The melting point of OB is lesser than OB1. However, the latter has a high melting point of about 360 degrees. Therefore, it is unsuitable for high-temperature products, and OB can be used in such cases. On the other hand, OB1 can be used in materials that require high-temperature processing.

  5. Difference Between Optical Brightener OB And Optical Brightener OB-1 OB and OB1 vary in different aspects. Here are some of the fundamental differences:

  6. 1. Melting point The melting point of the Optical Brightener is 200 degrees which is lower than the Optical Brightener-1, which is 360 degrees. This largely determines the application of both the Optical Brighteners. 2. Dispersion Dispersion mainly defines the stability of the application. A product with good dispersibility will have a long-lasting whitening effect, and the product’s yellowness will be very slow. OB is known to have better dispersibility and stability than OB-1. This is why OB is recommended to be used in ink coatings as the OB is not prone to the yellowing that might start early with OB-1.

  7. 3. Price Price becomes a decisive point in making decisions on selection when the Optical Brightener is used on a larger scale. OB is way costlier than OB-1. Most manufacturers choose the latter over the former as it’s cheap. However, specific applications such as special ink coatings need OB to manufacture. Therefore, innovations and R&D activities are finding a more affordable and more effective alternative to OB. Key Summary Optical brighteners have many applications. Both OB and OB-1 are important for their set of applications. Features such as dispersion and stability are significant from the commercialization point of view.
