Chiguard^® GA403

Novel UV Blocker Derived from Vanillin

Chiguard^® GA403 (GA403) is a novel UV blocker derived from vanillin. It has remarkably high absorption in the UV-A wavelength region.

At 1500 ppm loading in 1 mm thick PET film, GA403 can easily block UV light below 400 nm and up to 405 nm. This indicates that GA403 will have a low impact on the initial color.

Insolubility in Common Food Ingredients:
- Passed PET food contact migration tests in:
  - 10% ethanol
  - 3% acetic acid
  - Vegetable oil
- Currently under application for U.S. Food Contact Substance (FCS) notification.
Compatibility with Plastics:
- Despite low solubility, GA403 exhibits high compatibility with plastics such as:
  - PET
  - PC
  - PA
  - PMMA
  - PE
Heat Stability:
- Exceptional heat stability allows usage in plastics processed at temperatures over 300°C, such as PET, PC, and PA.

Chiguard^® 380W is recommended for use alongside GA403 to create a high efficiency and broad coverage UV blocking system.

Chiguard^® GA403 is recommended for use in the following applications:

✅ Beverage bottles, juice bottles
✅ PET food packaging materials
✅ Sunglass lenses
✅ Optical protective goggles
✅ Blue light-resistant screen protector
