Detergent powder and process for its preparation |
摘要 |
A spray-dried detergent powder contains from 15 to 40% by weight of anionic surfactant, from 20 to 70% by weight of sodium carbonate, from 5 to 20% by weight of sodium silicate and from 1 to 7.5% by weight of sodium bicarbonate, the weight ratio of sodium bicarbonate to sodium silicate being within the range of from 0.20:1 to 0.45:1. Optionally further sodium bicarbonate (up to 15% by weight) is postdosed to the spray-dried powder. The benefits of the invention are improved powder properties and, when further sodium bicarbonate is postdosed, mildness to hands.
