| 摘要 |
The object of the invention is to improve the method for the production of bulky, powdery and flowable preparations containing co-builders and an organic and/or inorganic carrier material which are suitable for the production of particle-shaped detergent and cleaning agents. This is substantially achieved by mixing an oxidised dextrin derivative with an inorganic builder, surfactant, and a large quantity of water so that a mixture which is flowable and which can be pumped at temperatures below 80 DEG C is produced. Water is removed from said mixture by means of drying gases at temperatures in the range of 160 DEG C to 260 DEG C until a powdery, flowable product is obtained. |
