Safety Information

Optical brighteners are generally safe but require handling precautions to avoid dust inhalation and skin contact. Use appropriate personal protective equipment including dust masks and gloves. Ensure adequate ventilation during processing. Some types approved for food contact and textile applications.

Dust Protection Required
Generally Safe Material
Light-Sensitive Storage

Storage & Handling

Store optical brighteners in cool, dry, dark conditions away from direct light and UV sources. Keep containers tightly sealed to prevent moisture absorption and photo-degradation. Use light-protected storage areas and handle under subdued lighting to maintain optical effectiveness.

Dark storage essential
Moisture protection critical
UV light protection
Activity preservation
