Performance Advantages

Choosing the right optical brightener is essential for maintaining competitive advantage in the detergent market. Our Optical Brightening Agent 31# offers several distinct benefits over generic alternatives:

• High Fluorescence Efficiency: Delivers exceptional whiteness enhancement even at low dosage levels, optimizing formulation costs.
• Excellent Solubility: Designed to dissolve readily in aqueous systems, ensuring uniform distribution within liquid or powder detergent matrices.
• Thermal Stability: Maintains performance integrity under various processing conditions encountered during industrial detergent production.
• Compatibility: Specifically engineered to work synergistically with common anionic surfactants without precipitating or losing efficacy.
• Cost-Effective Solution: Provides a balanced ratio of performance to price, allowing manufacturers to maintain healthy margins.

Industrial Applications And Dosage

This product is primarily utilized in the production of synthetic detergents for household and industrial laundry applications. It can be directly added into materials during the synthetic detergent production process, simplifying the manufacturing workflow. The recommended dosage typically ranges from 0.05% to 0.2% (% W/W Detergent), depending on the desired level of whiteness and the specific base formulation. Formulators should conduct small-scale trials to determine the optimal concentration for their specific product line. As a drop-in replacement for standard brighteners, it integrates seamlessly into existing production lines without requiring significant equipment modifications.

Packaging And Storage

To preserve the chemical integrity and fluorescence performance of Optical Brightening Agent 31#, proper storage protocols must be followed. The product is packaged in 25kg cartons or 25kg bags, with custom packaging available according to customer request. The shelf-life is established at 2 years when stored under room temperature conditions. It is imperative to store the material in a cool, dry environment, avoiding direct sunlight and moisture exposure, as UV degradation and humidity can negatively impact the powder's flowability and optical performance. We provide comprehensive Certificates of Analysis (COA) with every shipment to verify compliance with specified technical indices.
