Basic Information and Parameters

The Factory Supply Optical Brightener Ob with CAS number 7128-64-5 is a high - quality product offered at the best price. Optical brighteners are substances 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 (usually 420 - 470 nm). This gives treated materials a “whiter than white” appearance.

Some of the key parameters of this product include:

Chemical formula: The specific chemical formula of Optical Brightener Ob can be found in detailed chemical databases. It is a complex organic compound designed for optimal brightening effects.
Appearance: Typically, it appears as a white to off - white powder or granular form, which makes it easy to handle and mix with other substances.
Purity: High purity is maintained during the manufacturing process to ensure consistent and effective performance. The purity level can be customized according to different customer requirements, usually above a certain percentage to meet industry standards.
Solubility: It has a certain solubility in specific solvents, which is crucial for its application in different systems. The solubility characteristics determine its compatibility with various materials and processing methods.

Uses of the Product

The Factory Supply Optical Brightener Ob has a wide range of uses across different industries:

Textile Industry: It is widely used in the textile industry to enhance the whiteness and brightness of fabrics. Whether it is natural fibers like cotton, silk, and wool or synthetic fibers such as polyester and nylon, Optical Brightener Ob can significantly improve the visual appeal of the textiles. It is used in processes such as dyeing, printing, and finishing to make the fabrics look cleaner and more attractive.
Paper Industry: In the paper - making process, this optical brightener is added to improve the brightness and whiteness of paper products. It can be used in the production of various types of paper, including printing paper, writing paper, and packaging paper. By using Optical Brightener Ob, the paper can have a better color appearance and readability.
Detergent Industry: Detergents often contain optical brighteners to make washed clothes appear brighter. Factory Supply Optical Brightener Ob can be incorporated into laundry detergents, dishwashing detergents, and other cleaning products. It adsorbs onto the surface of the items being cleaned and reflects blue light, counteracting the yellowing effect that may occur over time.
Plastic Industry: It is also used in the plastic industry to enhance the brightness and color of plastic products. Whether it is transparent plastics or colored plastics, the addition of Optical Brightener Ob can improve the aesthetic quality of the final products.

How to Use the Product

The usage of Factory Supply Optical Brightener Ob depends on the specific application:

Textile Application: In the textile industry, it can be added during the dyeing or finishing process. The recommended dosage is usually based on the weight of the fabric. First, dissolve the optical brightener in an appropriate solvent according to the solubility requirements. Then, add the solution to the dye bath or finishing bath and mix well. The fabric is then treated in the bath under specific temperature and time conditions to ensure uniform absorption of the brightener.
Paper Application: For the paper industry, it can be added at the wet - end stage of the paper - making process. The brightener is usually prepared as an aqueous solution and added to the pulp suspension. The amount of addition depends on the desired brightness level of the paper. After addition, the pulp is further processed to form the paper sheet.
Detergent Application: In detergent production, it is added during the formulation process. The optical brightener is mixed with other detergent ingredients in the appropriate proportion. It is important to ensure uniform dispersion in the detergent matrix to achieve consistent brightening performance.
Plastic Application: When used in the plastic industry, it can be added during the plastic molding process. The brightener can be pre - mixed with the plastic resin before melting or added directly to the molten plastic. The dosage is determined by the type of plastic and the desired brightness effect.

User’evaluation of us

"vivalr is my partner for years. Met at 2014 Shanghai CPHI Expo. Not interested then as had stable supplier. In Sep 2016, original supplier couldn't guarantee quality and delivery. Thought of Zhai and his company first. So far, have stable business relationship and good personal friendship."

Marcus Long

" In years of sourcing from China, first found working with Sincere Chemical great. They help in production, delivery and tech, saving time. When first asking Zhai for optical brightener quote, got detailed one with prices, trade details, company info, R&D and production capacity, packaging and raw material control."

Emma Kung

" Hi, I'm Kim, Zhai's partner. Don't like him much (as he never gives more for my prices, haha), but still write customer feedback. Zhai's emails help me understand product and industry. Satisfied with his work ethic. He provides quotes and helps with work details, so I can focus on other things. He's the best supplier for me."
