| 摘要 |
<p>A phosphorus-free heavy duty synthetic organic detergent composition of improved cleaning power includes certain proportions of sodium linear higher alkylbenzene sulfonate, molecular sieve zeolite, preferably type 4A molecular sieve zeolite, percompound oxidizing agent which is either an alkali metal perborate tetrahydrate, an alkali metal percarbonate, an alkali metal carbonate peroxide or a mixture thereof, and sodium silicate of Na2O:SiO2 ratio in the range of 1:1 to 1:3.2. Preferably, the product also includes higher fatty alcohol polyethoxylate detergent. The invented product has satisfactory soil removal properties, comparable to those of similar products from which the percompound is omitted and in which the molecular sieve zeolite portion is doubled or in which the zeolite is replaced by twice as much pentasodium tripolyphosphate. Methods of laundering fabrics with the invented compositions are also described.</p> |
