Out of the salt one uses to flavour his food chemists make a great variety of products. Among these is a refrigerant used in preserving foods and cleaning solvents which remove dirt, grease and spots from clothing with the greatest of ease. Chlorine is also made from salt. It is widely used to safeguard the purity of water in municipal systems and in swimming pools, as well as for bleaching paper and texitles. Another product of salt is sodium peroxide which is used to bleach all kinds of textile fibers, particularly cotton. Sodium perborate,, which is a beneficial ingredient of tooth powders and mouth washes, is also derived from salt.
