Description

浓缩的织物柔软组合物
本发明涉及织物柔软剂。本发明的组合物被浓缩成在稀释时仍保持粘度的水性织物柔软组合物。
浓缩水性织物柔软剂在现有技术中被广泛地描述，经常讨论的一个主题是这些浓缩组合物的粘度，实际上这些浓缩组合物是极其粘稠的，现有技术经常讨论的是控制或降低这些浓缩组合物粘度的方法。很少考虑的一个问题是这些浓缩组合物稀释后的粘度；实际上，已经发现此类浓缩组合物的粘度在稀释时显著下降，而这种粘度损失从消费者来看是明显不希望的。
本发明的目的在于提供一种浓缩水性织物柔软组合物，在浓缩型中有着可接受的粘度，当它被稀释后仍保持可接受的粘度。
该技术问题曾在GB2007734中讨论过，该专利提议采用有二个长链烷基的脂肪酸季胺盐与油状物组成的混合物。
浓缩水性织物柔软剂还在EP56,695,EP13780,DE2631114和EP60003中描述过，EP-A-316996中还公开了制备浓缩织物柔软剂组合物的工艺。
现在已经发现上述目的可通过配制浓编水性织物柔软组合物来实现，该组合物，包括10～35％重量的阳离子织物柔软活性物或它们的混合物，上述组合物还包括：
一全部组合物重量0.3～3％的式为RO(Etox)n的直链脂肪醇乙氧基化物，其中R是C8-C18的直链烷基，n代表的重均乙氧基化度是3～35，或它们的混合物；
一全部组合物重量的0.5～6％的非离子亲水聚合物，或它们的混合物；
一全部组合物重量的0～2％的高支链化脂肪醇，有8～18个碳原子，或它们的混合物；
一全部组合物重量的0～0.5％的直链或环状聚二烷基硅氧烷，表达式如下：
其中，R是C1-C5链烷基，m是1～500的整数，或它们的混合物。
本发明还提供了一种用于柔软织物的方法，其中，上述浓缩组合物在接触漂洗水中织物之前用水稀释。
本发明的组合物是一种浓缩织物柔软剂；所谓浓缩的，它表示组合物包括占全部组合物重量10～35％的阳离子织物柔软活性物或它们的混合物，最好是15～25％。所谓阳离子，它表示在浓缩柔软组合物中任何柔软化合物都是阳离子形式。适当的阳离子织物柔软活性物包括：
(ⅰ)表达式如下的无环季铵盐：

其中，R1=C15-C17饱和烷基，R2=C1-C4饱和烷基，Z=NH或O,A-是阴离子。
成份(ⅰ)的例子是已知的，
二烷基二甲基铵盐，如：

组份(ⅱ)和(ⅲ)的例子是甲基-二(牛脂基酰氨基乙基)(2-羟乙基)铵硫酸-甲酯和甲基-二(氢化牛脂基酰氨基乙基)(2-羟乙基)铵硫酸-甲酯，其中R1是无环脂族C15-C17烃基，R2是乙烯基，R5是甲基，R8是羟烷基，A是硫酸-甲酯阴离子；这些材料可以从Sherex Chemical Company购得，相应的商品名为Varisoft 222R和Varisoft110R。组份(ⅳ)的例子是1-甲基-1-牛脂基酰氨基-乙基-2-牛脂基咪唑啉鎓硫酸-甲酯和1-甲基-1-(氢化牛脂酰氨基乙基)-2-牛脂基咪唑啉鎓硫酸-甲酯。
其它合适的织物柔软活性物包括下列胺，它们以质子化形式存在于浓缩柔软组合物中；这些胺有如下表达式：
Figure C9210220200081
其中n是2或3，最好是2；R1和R2分别是，C8-C30烷基或链烯基，优选C12-C20烷基，更好的是C15-C18烷基，或这些烷基的混合物。这些混合物的例子是从椰油中得到的烷基，“软质”(非硬质)牛脂，和硬化牛脂。Q是CH2或N，优选N，X是R4
Figure C9210220200091
其中，T是O或NR5,R5是H或C1-C4烷基，优选H,R4是二价C1-C3亚烷基或(C2H4O)m，其中m是1-8的整数；或X是R4。
按上述表达式最优选的柔软剂是下式表示的咪唑啉。
Figure C9210220200092
和
Figure C9210220200093
其中R1是牛脂基。
上述描述的柔软胺适用于本发明的目的，它们以质子化形式存在于浓缩柔软组合物中；EP199383描述了一种适宜的用来质子化这些胺的方法。
这里所用的优选柔软活性混合物是一种混合物，含20-70％重量的二牛脂基二甲基氯化铵(DTDMAC)柔软活性物，30-80％的二牛脂基咪唑啉。优选地，本发明浓缩组合物包括15-25％重量的这类混合物的整理产品。
本发明各种优选实施例中，柔软活性物包括二牛脂基咪唑啉酯，如前述描述的那样(即，当前述表达式T是O,R1和R2都是牛脂基时)。该实施例由于环境理由而尤其优选。
本发明组合物还包括，全部组合物0.3～3％重量的直链脂肪醇按表达式RO(Etox)n乙氧基化物，其中R是直链C3-13烷基，n代表乙氧基化程度的重均值，在3～35之间，或它们的混合物。优选的是乙氧基化直链脂肪醇，其中R有10～13个直链碳原子，n为5～10，优选8。优选地，这些化合物，或它们的混合物以全部组合物重量的1～1.5％的量存在。这些化合物可从BASF购得，商品名LUTENSOLTO。
本发明组合物还包括组合物重量的0.5～6％，优选1.5～2.5％的非离子亲水聚合物，或它们的混合物。这些适当的聚合物包括聚乙二醇，聚丙二醇，聚乙烯醇及类似物。尤其优选的是分子量在30O～50000的聚乙二醇，优选分子量2000～10000。在此优选的实施例中，柔软活性物是DTDMAC和二牛脂基咪唑啉的混合物，优选采用分子量4000的聚乙二醇。在各种优选的实例中，柔软活性物包括二牛脂基咪唑啉酯，优选采用分子量8000的聚乙二醇。
本发明组合物还包括全部组合物重量0-2％，优选0～0.1％的高支链化C3-13的脂肪醇、优选C12-14，或它们的混合物，最好是C13。类似于上述高支链化脂肪醇的支链化化合物经常存在于香料中；因而，加到组合物中的上述高支链化脂肪醇的任何加入量必须按所用的香料来调节，适用于本发明组合物的此类高支链化脂肪醇可从EXXON购得，商品名EXXAL。
本发明组合物还包括全部组合物重量0～0.5％的直链或环状聚二烷基硅氧烷，表达式如下：
其中R是C1-C5的烷基，m是1-500的整数，或它们的混合物。上述聚二烷基硅氧烷组份不是本发明组合物的基本成份，当组合物要在稀释时保持粘度时甚至缺乏这类聚二烷基硅氧烷。但是，能从这些聚二烷基硅氧烷中得到几方面好处，包括改善了整理产品的稳定性，改进处理织物的吸水性。上述聚二烷基硅氧烷也有助于避免在洗涤机的分散器中形成织物柔软剂残余物。因而，本发明优选组合物包括0.05～0.5％，量好是全部组合物重量0.1～0.3％的上述聚二烷基硅氧烷，或它们的混合物。本发明组合物中，柔软活性物包括前面描述的二牛脂咪唑啉酯，优选采用聚二烷基硅氧烷，R是甲基，m约是200。在其它组合物中，优选采用的聚二烷基硅氧烷，R是甲基而m是7。适宜的聚二烷基硅氧烷可从DOWCORNING购得，商品名200液体，在所采用的优选聚二烷基硅氧烷是DOW CORNING′S200液体350CS(R是甲基m是203)，和5CS(R是甲基和m是7)。
本发明组合物另外还包括常规组份如香料，防腐剂，杀菌剂，着色剂，防霉剂，稳定剂，增白剂，遮光剂及其类似物，采用常量，即最多达组合重量的5％。
浓缩形式的组合物在60RPM剪切速率下粘度40～400CPS。本发明组合物可直接采用浓缩形式，或优选在使用前进行稀释。本发明组合物是指在水中稀释，优选在它们重量的2-3倍的水中。稀释形式，组合物在60RPM剪切速率下粘度为20～60CPS，优选60RPM剪切速率下30～50CPS。

上述组合物可通过向60～65℃的水中加入HCl，并在80～85℃下搅拌，10分钟内向溶液加入熔融的二牛脂二甲基氯化铵，二牛脂基咪唑啉和Lutensol T08预混合物。然后将CaCl2的水溶液在约5分钟内注入。然后加入香料和硅油的混合物。然后将组合物冷却到室温。最后将分子量4000的50％的聚乙二醇溶液加入。
最后得到的稀释前的组合物粘度约65CPS，用其2倍重量的水稀释后粘度50CPS。
         例2
制备的组合物含有：
