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.

Abstract: The present invention discloses a glass composition for an eco-friendly detergent, and a method for preparing glass powder for an eco-friendly detergent by using same, wherein the glass composition based on borate-based glass containing large amounts of MgO, CaO, K2O, Na2O, and B2O3 and a trace amount of SiO2 exhibits maximized elution of ions such as K+, Na+, Ca2+, Mg2+, etc., whereby a high concentration of eluate can be prepared. As a result, the glass composition for an eco-friendly detergent and the method for preparing glass powder for an eco-friendly detergent allow for the repeated use of a certain amount of glass and can uniformly maintain cleansing performance even to 40 cleansing rounds or more.
