Why do some clothing labels say Use a nonchlorine bleach?

Some clothing labels recommend using a nonchlorine bleach because chlorine bleach can be harsh and damaging to certain fabrics. Nonchlorine bleach, also known as oxygen bleach, uses hydrogen peroxide or sodium percarbonate instead of chlorine. It is gentler on fabrics and can help remove stains without causing damage or discoloration. Additionally, chlorine bleach can be harmful to the environment, while nonchlorine bleach is considered more eco-friendly.

Most casual clothes labels say not to use chlorine bleach because non-chlorine bleach is much gentler on laundry than traditional chlorine bleaches. It doesn't cause skin irritation and doesn't leave an unpleasant odor on the laundry. Chlorine-free bleaches are great at removing stains and dirt, leaving your laundry fresh and clean.
