NINGBO INNO PHARMCHEM CO.,LTD. is pleased to present our high-quality Optical Brightening Agent BAC, a leading solution for achieving brilliant whiteness in textile applications. This essential chemical auxiliary, identified by its C.I. Number 363 and CAS No. 95078-19-6, is specifically designed to enhance the visual appeal of various fibers by converting ultraviolet light into visible blue light, thereby masking yellowness and significantly increasing brightness.

The choice of an optical brightener is critical for textile finishing, as different fibers require different types of brighteners based on their chemical structure and the processing conditions used. Optical Brightening Agent BAC, with its cationic character and specific chemical structure (a Benzimidazol derivative), is particularly well-suited for synthetic fibers such as acrylics and di-acetates where it shows excellent substantivity and effectiveness.

Optical Brightening Agent BAC is supplied as a slightly brown liquid, offering ease of handling and excellent dispersibility. It exhibits cationic ionicity and maintains a pH level around 4-6. A key advantage is its exceptional stability. The product demonstrates good stability to hard water, very good stability to acids, very good stability to chlorite, very good stability to hypochlorite, and very good stability to hydrosulphite, making it versatile for use in various dyeing and finishing processes. Its stability to alkalis is noted as not stable, a crucial detail for process planning. The resulting shade achieved is typically neutral to bluish, providing a desirable cool white effect on treated materials.

The liquid form of Optical Brightening Agent BAC provides significant advantages in handling, storage, and application compared to powder forms. It can be easily diluted and mixed into processing baths, ensuring uniform distribution and consistent results across large batches of material. Its physical state contributes to safer handling environments and minimizes airborne dust concerns, enhancing operational efficiency in textile mills.

The primary application focus for Optical Brightening Agent BAC is on acrylic fabrics and di-acetate fibers. It is highly effective for both exhaustion and padding application methods. One of its most significant benefits is the requirement for a relatively low dosage to achieve outstanding levels of whiteness. This efficiency translates into cost savings and reduced environmental impact for textile manufacturers. The product functions as a vital whitening agent and dyeing auxiliary, ensuring textiles meet high standards for brightness and appearance.

This brightener is not limited to specific yarn or fabric structures but can be applied effectively to various forms of acrylic and di-acetate textiles, including staple fibers, filament yarns, knitted fabrics, and woven materials. The resulting high level of whiteness achieved with Optical Brightening Agent BAC is permanent and resistant to washing, ensuring the longevity of the brightening effect throughout the product's lifecycle. Its performance under different finishing conditions ensures flexibility in textile processing.

NINGBO INNO PHARMCHEM CO.,LTD. ensures that our Optical Brightening Agent BAC meets rigorous specifications. The product is typically supplied with a purity of ≥ 99.0% and a UV strength specification of 115 ±5. Storage is recommended in a sealed condition, maintaining room temperature for a shelf life of 12 months. Standard packaging is in 30kg or 25kg plastic drums, although customization based on customer requests is available.

Optical brighteners like BAC are integral to the modern textile industry. Unlike bleaches which chemically remove color, brighteners are fluorescent dyes that absorb light in the ultraviolet spectrum and re-emit it in the visible blue region. This phenomenon makes materials appear whiter and brighter by compensating for the natural yellowing tendencies of fibers. The selection of the appropriate brightener depends heavily on the fiber type and the processing conditions, making Optical Brightening Agent BAC a tailored solution for acrylics and di-acetates.

As a dedicated manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing high-quality chemical raw materials globally. Businesses looking to purchase or buy Optical Brightening Agent BAC can inquire directly to obtain competitive price information.
