This detergent is a complete product, replacing separate addition of alkalies and detergents, simplifies washing formulas, saves time and labor involved in purchasing, handling, and storage of supplies. It contains special optical brighteners to produce sparkling white shirts, table linens, bar aprons, towels, and bed linens. It is gentle and effective on all color-fast fabrics as well. Its free-flowing powders dissolve easily and will not break down even at high temperatures.
