Pegasus is a highly active oxidizing and bleaching agent based on the sodium peroxy compounds. In powder form, it provides and easy-to-use source of active peroxy compound to provide high levels of stain removal and color retention on white work. On colored work, it provides a means of removing bleachable stains not treatable with chlorine-based bleaches. Thus it is ideal for the treatment of stained colored table linen (polyester, polyester/cotton, cotton or linen). It is also particularly suited to the removal of mildew from fabrics, either by normal in-the-wash treatment during the hot stage of the wash, or by soaking treatment in a cold bath. Either method provides a means of removing mildew without unduly attacking the fabric. Pegasus does not contain optical brightening agents (OBA) so it can be used on colored work without fear of problems caused by OBA absorption onto colored articles.
