The invention comprises liquid, non-aqueous compositions comprising:
liquid nonionic surfactant in an amount of 25 to 75% by weight; having suspended therein
20 to 75% of solid particulate material with a surface weighted mean particle size in the range 1 to 100µ which comprises a combination of
i) from 5 to 72% by weight of one or more salts which form hydrate(s) stable at 20°C but are present in an anhydrous or incompletely hydrated state, together with
ii) from 3 to 70% by weight of one or more salts which has no stable hydrate at 20°C.
The combination of hydratable and non-hydratable salts enhances suspending properties while inhibiting excess gelling.
本发明包括液态非
水性组合物,其中包括
液态非离子表面活性剂,含量为 25% 至 75%(按重量计); 其中悬浮有
20% 至 75% 的固体颗粒材料,其表面加权平均粒径范围为 1 至 100µ,由以下材料组合而成
i) 5-72%(按重量计)的一种或多种盐,这些盐在 20℃时形成稳定的
水合物,但 以无
水或不完全
水合状态存在,以及
以重量计,3%至 70%的一种或多种盐,在 20°C 时没有稳定的
水合物。
水合盐和非
水合盐的组合可增强悬浮特性,同时抑制过量胶凝。
