<p>The heavy duty washing powder contains a detergent which essentially consists of an alkoxylated alcohol as non-ionic surface-active agent in an amount of 5 to 50% by weight, a water-soluble soap in an amount of 10 to 30% by weight and sodium tripolyphosphate in an amount of 10 to 25% by weight, which corresponds to a total P content of 6% by weight. The alkoxylated alcohol is normally an ethoxylated alcohol, i.e. a C12-15-alcohol which is ethoxylated with 4 to 25 mol, preferably 4 to 12 mol, of ethylene oxide per mol of alcohol. A preferred washing powder mixture contains the water-soluble soap as a mixture of 45 to 60% by weight of non-hardened tallow soap, 20 to 30% by weight of coconut oil soap and 15 to 25% by weight of soap from hardened rape oil.</p> |
