Description
本发明涉及流体洗涤剂组合物,它包括多羟基脂肪酸酰胺,硅氧烷防沫组合物,和阴离子的、非离子的或两性的表面活性剂。该硅氧烷防沫组合物包括初级防沫剂,非离子的硅氧烷表面活性剂,和聚乙二醇或聚乙二醇/聚丙二醇的共聚物,该聚乙二醇或共聚物在室温条件下按重量百分比计算在水中的溶解度约为2%以上。
在Aizawa等人的1987年1月27日批准的US 4,639,489号专利和1988年6月7日批准的US 4,749,740号专利以及Starch的1990年12月18日批准的US 4,978,471号专利和1991年1月8日批准的US 4,983,316号专利中分别描述了硅氧烷防沫组合物及其制造方法。
在1992年4月16日公开的公开号为WO-92-06154的专利申请中对包括多羟基脂肪酸酰胺的液体洗涤剂组合物进行了描述。而阴离子的,非离子的和两性的表面活性剂则是已公知的液体洗涤剂组合物的组分。
人们已经发现用现有的硅氧烷防沫组合物来配制成含多羟基脂肪酸酰胺的液体洗涤剂组合物是困难的。上述组分在形成所需洗涤剂组合物的几天后便分离开了。即使上述组分配制成贮存的稳定的产物,它们也必须能有效地控制液体洗涤剂中的泡沫。因为人们不希望在洗涤设备中存有大量泡沫。
现在发现当以在室温条件下在水中的溶解度按重量百分比计大于2%的聚乙二醇(PEG)和/或聚乙二醇-聚丙二醇的共聚物(PEG/PPG)代替硅氧烷防沫组合物中的聚丙二醇(PPG)时,可配制出一个稳定的、低泡沫的液体洗涤剂。该流体洗涤剂组合物包括多羟基脂肪酸酰胺,该组合物在贮存时可保持均匀。包括有聚乙二醇和/或聚乙二醇-聚丙二醇的共聚物的硅氧烷防沫组合物与包括有聚丙二醇的硅氧烷防沫组合物相比,可大大降低出现在洗涤设备中所配制的洗涤液中的泡沫量。
本发明涉及一种均匀的液体洗涤剂组合物,它包括:
a.按重量百分比计算为约1~30%的多羟基脂肪酸酰胺;
b.按重量百分比计算为约0.001~1%的硅氧烷防沫组合物,该组合物包括:(1)初级防沫剂的非水乳液,该防沫剂为一种混合物,该混合物包括(a)一种聚有机硅氧烷,(b)一种树脂状硅氧烷或形成硅氧烷树脂的硅氧烷化合物,(c)一种细颗粒填料和(d)促使上述混合物成分(a),(b),(c)一起发生反应从而形成硅氧烷醇盐的催化剂;(2)至少一种非离子的硅氧烷表面活性剂;和(3)聚乙二醇或聚乙二醇/聚丙二醇的共聚物,上述聚乙二醇或共聚物在室温条件下按重量百分比计算在水中的溶解度约大于2%,另外该硅氧烷防沫组合物中不含聚丙二醇;
c.按重量百分比计算约为1~50%的阴离子的,或两性或另外一种非离子的表面活性剂。
本发明的洗涤剂组合物包括多羟基脂肪酸酰胺,硅氧烷防沫组合物,和阴离子的,非离子的或两性的表面活性剂。下面对上述成分进行描述。

在Starch的于1991年1月8日批准的US 4,983,316号专利及Starch的于1990年12月18日批准的US 4,978,471号专利中对初级防沫剂和非离子的硅氧烷表面活性剂进行了描述,上述两篇专利在这里被参考引用了。
对于二级防沫剂一般人们不首先采用,但是在硅氧烷防沫组合物中还是可以采用的。优选的二级防沫剂是粘度约为1000厘沲的聚二甲基硅氧烷。在硅氧烷防沫组合物中还可包括稳定剂和保存剂,该稳定剂和保存剂也在上述的Starch专利中进行了描述。
硅氧烷防沫组合物在液体洗涤剂组合物中可分散或易于分散开,这样可对泡沫进行控制,并使洗涤剂组合物保持均匀。
在Aizawa等人的US 4,639,489和US 4,749,740号专利中对可供选择的最好的初级防沫剂成分进行了描述,上述两篇专利在这里被参考引用了。具体来说上述专利的第1栏第46行~第4栏第35行对优选的硅氧烷防沫组合物进行了描述。
为了使初级(和二级)防沫剂能分散于水介质,如液体洗涤剂中,在防沫组合物中至少还发包括一种非离子的硅氧烷表面活性剂,该表面活性剂用来使溶剂中的防沫剂乳化。一种合适的非离子的硅氧烷表面活性剂为树脂状硅氧烷和聚烯化氧的共聚物。

硅氧烷防沫组合物不包括聚丙二醇,特别是分子量为4000的聚丙二醇,该聚丙二醇在以前用作溶剂。较好的硅氧烷防沫组合物不包括环氧乙烷和1,2-环氧丙烷的嵌段共聚物,如商标为Pluronic L101的产品。
较好将初级(和二级)防沫剂与非离子的硅氧烷表面活性剂一起在下述溶剂中混合并使其乳化,该溶剂为聚乙二醇和/或聚乙二醇/聚丙二醇的共聚物,上述溶剂成分在水中的溶解度按重量百分比计算约大于2%。然后,将上述生成物加入到液体洗涤剂中。

作为优选的用作液体洗涤剂组合物的阴离子的表面活性剂的一种可采用烷基磺酸盐。之所以选用该种表面活性剂是因为它可利用可更新的非石油资源制成。该种烷基酯磺酸盐表面活性剂组分的制备可根据技术文献中所描述的已有方法进行。比如,根据“美国石油化学学会期刊”第52期(1975),第323~329页中的描述,可让C8-C20羧酸直链酯与SO3气体进行磺化反应。合适的初始材料包括由脂,棕榈树、椰子油等衍生得到的天然脂肪型物质。
特别用于洗涤目的的优选的烷基酯磺酸盐表面活性剂包括具有下述结构式的烷基酯磺酸盐表面活性剂,该结构式为:

在这里使用的第二种重要的阴离子的表面活性剂为烷基磺酸盐表面活性剂。当该表面活性剂与多羟基脂肪酸酰胺一起使用时除了提供极好的综合去污能力(见下面),包括在一个宽的温度,洗涤浓度和洗涤时间范围内具有良好的油脂/油去除性以外,不仅改进了分子式为ROSO3M的水溶性盐或酸在液体洗涤剂配方中的配制能力,而且还能使烷基硫酸盐的溶解能力增加,其中R较好为C10-C24烃基,当然R为具有C10-C20烷基成分的烷基或羟烷基时则更好,而其以C12-C18烷基或羟烷基为更加好,M为氢或阳离子,如碱金属阳离子(例如钠、钾、锂离子),取代的或未取代的铵阳离子,如甲基铵阳离子、二甲基铵阳离子、三甲基铵阳离子和季铵阳离子,例如四甲基铵和二甲基哌啶鎓,和由链烷醇胺衍生得到的阳离子,该链烷醇胺例如为乙醇胺,二乙醇胺,三乙醇胺或上述成分的混合体。在较低洗涤温度条件下(如约在50℃以下)较好采用C12_16烷基链,而在较高洗涤温度条件下(如约在50℃以上)较好采用C16_18烷基链。
用于本发明洗涤剂组合物的第三种优选的阴离子的表面活性剂为烷基烷氧基化硫酸盐表面活性剂。该表面活性剂为具有下述结构式的溶于水的盐或酸,该结构式为RO(A)mSO3M,其中R为未被取代的C10-C24烷基或具有C10-C24烷基成分的羟烷基,较好为C12-C20烷基或羟烷基,而更好为C12-C18烷基或羟烷基,A为乙氧基或丙氧基,m为大于零的数,一般它约在0.5~6的范围内,更好约在0.5~3的范围内,而M为氢或阳离子,例如,该阳离子可以为金属阳离子(如钠,钾,锂,钙,镁离子等),铵或取代的铵阳离子。在这里打算采用烷基乙氧基化硫酸盐及烷基丙氧基化硫酸盐。上述的取代的铵阳离子包括甲基-,二甲基-,三甲基铵阳离子和季铵阳离子,如四甲基铵,二甲基哌啶鎓阳离子,和由链烷醇胺衍生的阳离子,该链烷醇胺例如为一乙醇胺,二乙醇胺,三乙醇胺,和上述成分的混合物。典型的表面活性剂是C12-C18烷基多乙氧基化。(1.0)硫酸盐,C12-C18烷基多乙氧基化(2.25)硫酸盐,C12-C18烷基多乙氧基化(3.0)硫酸盐,和C12-C18烷基多乙氧基化(4.0)硫酸盐,此处M可很方便地选自钠和钾离子两者之一。
2 非离子的表面活性剂
较好的非离子的表面活性剂为C10-C20醇的缩合物,并且每摩尔醇中约含2~20摩尔泊环氧乙烷(“E2 _20乙氧基化的C10_20醇”)。当然该表面活性剂也可为多羟基脂肪酸酰胺。
在1975年12月30日批准的Laughlin等人的US 3,929,678号专利第13栏第14行~第16栏第6行中给出了合适的非离子洗涤剂用表面活性剂的实例,上述专利在这里被参考引用了。下面以举例方式给出可使用的几类非离子表面活性剂,当然非离子表面活性剂可不限于所列的几类。
