Performance
Anti-phenolic yellowing agent can be used for various nylon and blended fabrics containing
elastic fibers to prevent yellowing caused by BHT (2, 6-Dibutyl-hydroxy-toluene). BHT is often used
as an antioxidant when making plastic bags, and white or light-colored clothes are very likely to turn
yellow when they are placed in such bags.
In addition, because it is neutral, even if the dosage is high, the pH of the treated fabric can be
guaranteed to be between 5-7.

for automatic dosing systems.
