Abstract: Disclosed are an environmentally-friendly glass composition for laundry detergents and washing supplements, and a method for manufacturing a glass powder thereof, wherein the glass composition is a borate glass containing large amounts of K2O and Na2O and a small amount of SiO2, and the elution properties of ions are maximized, thus enabling the production of a high concentration of elution water. As a result, the present invention uses to advantage the low chemical durability of borate glass, which is a major disadvantage of borate glass, and thereby maximizes the elution properties of the glass to form a large amount of OH− ions and B(OH)4− ions within a short period of time, and thus can exhibit excellent washing power during the washing of laundry.
