Although there is no present adequate proof, it has been postulated that the phosphorus-containing builders present in detergent compositions can be a factor in eutrophication. Therefore any substitutes which do not contain phosphorus may decrease to some extent the eutrophication.
It is therefore an object of the present invention to provide novel compounds which are useful as detergent builders. It is another object of the present invention to provide novel compounds which function as surface active agents and as detergent builders. It is still another object of the present invention to provide detergent compositions which are free of phosphorus-containing builders such as the alkali metal condensed phosphates. Electrophotography is a system in which a latent image formed on a photoconductive solid member using its photoconductivity is developed by allowing a toner in the form of colored particles to electrostatically adhere thereto, and the thus developed toner image is transferred and then fixed on a paper, etc. The electrophotographic system has been extensively used in the applications such as copying machines and printers, and further recently applied to general printing machines.
In the electrophotographic development, when using a toner having no magnetism, carrier particles called a magnetic carrier have been used together with the toner. The magnetic carrier serves not only for imparting an adequate amount of a positive or negative electrical charge to the toner owing to frictional electrification therebetween, but also for delivering the toner through a developing sleeve accommodating a magnet to near the surface of a photosensitive member on which a latent image is formed, by utilizing a magnetic force of the developing sleeve (A mixture of the magnetic carrier and the toner, etc., is a developer which is ready for immediate development of the latent image). In recent years, in the field of electrophotography, coloration of toner images developed tends to rapidly proceed. However, a color toner used for the above purpose has no magnetism, and there is therefore a rapidly increasing demand for the magnetic carrier. At the same time, there is a demand for a high quality of the resulting color images and a high copying speed thereof. To meet the requirements, the magnetic carrier is also required to have further improved functions.
Hitherto, as a material of a central portion of the magnetic carrier (hereinafter occasionally referred to as a “carrier core”) or a material of

 Although there be no present adequate validation, it has been postulated that the phosphorus - containing builders present in detergent compositions can be a gene in eutrophication. Therefore any substitutes which do not hold morning star may decrease to some extent the eutrophication. 
 It is therefore an object of the present invention to leave novel compounds which are utilitarian as detergent builders. It is another object of the present invention to provide fresh compounds which function as surface active agents and as detergent builders. It is however another object of the present invention to provide detergent compositions which are free of phosphorus - hold builders such as the alkali metal condensed phosphates. Electrophotography is a system in which a latent trope shape on a photoconductive solid member using its photoconductivity is developed by allowing a toner in the form of biased atom to electrostatically adhere thereto, and the thus modernize toner prototype is transferred and then fixed on a paper, etc. The electrophotographic system has been extensively used in the applications such as copying car and printers, and further recently applied to general printing car. 
 In the electrophotographic development, when using a toner having no magnetism, carrier particle called a charismatic mailman have been used together with the toner. The magnetic carrier serve not only for imparting an adequate amount of a incontrovertible or negative electrical charge to the toner owing to frictional electrification therebetween, but besides for delivering the toner through a developing sleeve accommodating a magnet to near the surface of a light-sensitive member on which a latent image is formed, by utilizing a charismatic force of the developing sleeve (A mix of the magnetic carrier and the toner, etc. , is a developer which is quick for immediate development of the latent image). In recent years, in the field of electrophotography, coloration of toner images developed tends to rapidly proceed. However, a semblance toner used for the above purpose have no magnetism, and there is therefore a rapidly increasing demand for the magnetic mailman. At the same time, there is a demand for a high quality of the resulting semblance picture and a high copying speed thence. To meet the requirements, the magnetic aircraft carrier is also required to have further improved functions. 
 Hitherto, as a material of a central portion of the charismatic carrier (hereinafter occasionally referred to as a “ carrier core ”) or a material of
