Recommended loading concentrations for OB-1 range between 50 and 1000 ppm(0.005-0.1%). The product can be used alone or in a variety of blends and combinations with other additives, including antioxidants, processing stabilizers, and light stabilizers. Higher load levels of Syntex OB-1 are required if it is used in combination with a UV absorber. The exact formulation to be used is dependent on the substrate, performance requirements, and other factors, and should be determined by the user based on testing to simulate actual conditions of use. Due to the high melting point of the product (359℃), care must be taken to ensure complete dispersion when Syntex OB-1 is used in polymers processed at lower temperatures such as styrenics and acrylics.

OB-1 is recommended to increase the whiteness of polyester and polyamide (nylon) fibers as well as in high temperature engineering plastics, including polycarbonates, polyesters, and polyamides (nylon). It is also suitable for use in styrenic and acrylic polymers.
Packing and Storage:
In accordant with good industrial practice, handle with care and prevent contamination of the environment. Avoid dust formation and ignition source.
For optical brighteners, the program encourages manufacturers to use those that pose "low toxicity to humans and the environment both as parent chemicals and degradation byproducts." Optical brighteners aren't readily biodegradable and may bioaccumulate, so they pose a potential hazard to aquatic life.
