Abstract
The present disclosure provides compositions for fabric treatment having at least one dye transfer inhibitor (DTI), at least one water-soluble carrier, at least one fragrance, and at least one buffer system, and other optional ingredients. During a wash cycle, the compositions disclosed herein significantly boost color fading protection of fabrics. The present disclosure further provides a method of making a composition for fabric treatment, including mixing a water-soluble carrier and a buffer system to form a mixture; adding a dye transfer inhibitor (DTI) and a fragrance into the mixture; mixing the mixture; heating the mixture and obtaining a melt thereby; and cooling the mixture. The method can further include shaping the melt into individual particles having melt bodies, which can optionally be in the form of a pastille.
