DETERGENT POWDERS AND PROCESSES FOR PRODUCING THEM |
摘要 |
<p>The formation of poorly-dispersible material by interaction between sodium silicate and sodium aluminosilicate in a detergent powder can be reduced my acidification of the slurry prior to spray-drying. An acid in an amount equivalent to from 1.5 to 3 parts by weight of hydrogen chloride per 6 parts of sodium silicate of sodium oxide to silica ratio 1 to 1.6 is added to precipitate at least part of the silicate. Optionally, a powder-structurant is present.</p> |
