CAN/CGSB-2.33-92

1.1 This standard states physical and chemical requirements for a built sodium soap in powder form, suitable for commercial and institutional laundering. 1.2 The soap is intended for use in soft water (calcium cabonate hardness up to 120 mg/L). In locations where water hardness exceeds 120 mg/L (as calcium carbonate), an appropriate synthetic detergent composition would be more satisfactory and economical. The builders referred to in this standard are generally alkaline salts and are added to increase the soap's effectiveness in removing oil. See CAN/CGSB-2.34 for guidance on the choice of soaps and detergents.
