NINGBO INNO PHARMCHEM CO.,LTD. understands that the efficacy of a laundry detergent is often judged by its ability to deliver bright, clean whites. Optical brighteners play a critical role in achieving this, and selecting the appropriate one is key to product success. This guide explores the common types and benefits of optical brighteners used in detergent formulations.

Optical brighteners, also known as fluorescent whitening agents (FWAs), work by absorbing UV light and emitting blue light. This process masks yellowness and enhances the perceived whiteness of fabrics. Two prominent examples frequently used in the industry are Optical Brightener CBS-X and Optical Brightener NFW. While both serve the primary purpose of whitening, they possess distinct characteristics that make them suitable for different applications and consumer needs.

Optical Brightener CBS-X is highly regarded for its effectiveness in laundry detergents, particularly for cellulose fibers and in both warm and cold water washes. Its ability to provide a strong whitening effect, coupled with excellent stability in concentrated liquid detergents and resistance to chlorine bleaching, makes it a popular choice. The fluorescent whitening agent CBS-X benefits are also evident in its durability through repeated washing, preventing fabric yellowing. For manufacturers looking to buy optical brightener powder for advanced detergent formulations, CBS-X is often a primary consideration.

Optical Brightener NFW, on the other hand, is particularly noted for its performance on synthetic fibers like nylon, as well as wool and silk. It offers good pH stability and resistance to bleaching agents, making it a versatile option. While CBS-X might be more universally applied across various detergent types, NFW's specific strengths make it ideal for targeted fabric care within a detergent product line or for specialized cleaning agents.

The correct textile optical brightener dosage is crucial for both performance and safety. Typically, detergents will contain small percentages of these agents, carefully calibrated to achieve the desired whitening effect without causing oversaturation or unwanted side effects. For example, a general detergent whitening agent formula might include 0.05-0.40% of an optical brightener, depending on its concentration and the overall detergent composition.

When formulating detergents, manufacturers must consider the target fabrics and washing conditions. The choice between CBS-X and NFW, or even a combination of brighteners, depends on the desired whiteness level, fabric types to be washed, and the detergent's intended use (e.g., heavy-duty, delicates, or all-purpose). At NINGBO INNO PHARMCHEM CO.,LTD., we provide high-quality optical brighteners to support these formulation decisions, ensuring our clients can create effective and competitive laundry products that deliver the bright whites consumers demand.
