What type of soap is specifically formulated for chelating?

Chelating soap is specifically formulated to bind with metal ions and help remove them from surfaces, including hair and skin. This type of soap contains chelating agents that interact with minerals such as calcium and magnesium, which can be found in hard water. By binding these minerals, chelating soap prevents them from depositing on hair and skin, which can lead to build-up and dullness.

In contrast, antibacterial soap is designed primarily to kill or inhibit the growth of bacteria, and while it may offer some cleaning properties, it does not have the specific chelating function. Liquid soap and bar soap refer to the form of the soap rather than its specialized function; while either could potentially contain chelating agents, they are not specifically formulated for that purpose. Thus, chelating soap is the most accurate answer when discussing products designed for this specific function in hair and skin care.
