  • Patent number: 5658870
    Abstract: A composition of super molecule active solid cleaning agent manufactured from super molecules and inorganic chemicals consisting of suitable amounts in weight percent of an anionic surface active agent, a sodium carbonate, a sodium silicate, a fluorescent whitening agent, a carboxymethyl cellulose, a non-ionic surface active agent, a di-sodium edetate, an oleic acid and an essence. Water molecules can be activated by the active solid particles as they are immersed in the water. The active solid particles may rub with each other to generate excessive amount of negative hydroxyl ions (OH) in water. Accordingly, the pH value in water increases and the water molecules are activated. As a result, the activated molecules of water may readily penetrate into the tissue of the fabric to weaken and soften the connection between the dirt and tissue of the fabric. The dirt attached to fabric can be readily removed.
