Color-safe bleach uses hydrogen peroxide instead of sodium hypocholorite. While peroxide is a bleaching agent, it doesn't affect the dyes in many types of fabrics, so it won't change the fabric's color. If unsure whether your colorful clothing or other fabrics will hold up to a color-safe bleach, test it by pouring a small amount of the color-safe bleach on an inconspicuous area of the fabric and let it sit for 30 minutes or so before rinsing it out.

Irritating to eyes and skin.
Keep out of the reach of children. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. If swallowed seek medical advice immediately and show this container or label. Do not mix with other bleaching agents. After use, rinse hands thoroughly or especially in case of sensitive skin, wear gloves. The hydrogen peroxide contained in Ace may have a temporary and reversible effect on the skin (e.g. whitening).
