Soil release polyetheresters and detergent compositions containing them |
摘要 |
<p>A water-soluble copolyester comprising units of a polyglycol or capped polyglycol (for example, polyethylene glycol or polyethylene glycol methyl ether), an aromatic dicarboxylic acid (for example, terephthalic acid) and at least mole% of a polyol having at least three hydroxyl groups (for example, glycerol), but free of ethylene glycol units, is a highly effective soil release polymer for use in detergent compositions. The aromatic dicarboxylic acid units may include units of a sulphonated aromatic dicarboxylic acid (for example, sulphoisophthalic acid).</p> |
