    HazMat Fee

    An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

    The shipment is processed through FedEx Ground under the Limited Quantity option.

    Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

    If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

2-Hydroxy-4-(octyloxy)benzophenone (HOBP) is a UV based absorber that has 2-hydroxybenzophenone as a functional group. It can be used to enhance the light fastness of polymers using UV absorbers with sulfur and phosphorus compounds.HOBPs are UV absorbers for insulating plastics, which can be incorporated with active layers to increase the stabilization of organic solar cells (OSCs). It may be incorporated in parylene C films to enhance the light stability, which can be potentially used as a moisture transfer membrane for electronic boards and photovoltaics.

Application

2-Hydroxy-4-(octyloxy)benzophenone serves as a stable, bench-ready UV absorber with proven utility in polymer stabilization and cosmetic formulations. Its ortho-hydroxy benzophenone core enables efficient hydrogen bonding and intramolecular proton transfer, enhancing photochemical durability. The octyloxy substituent improves solubility in nonpolar matrices while maintaining excellent thermal stability. Functions effectively in both polyolefin and resin systems, offering broad-spectrum protection against UV degradation without significant yellowing.
