技术领域
本发明涉及洗衣凝珠领域,具体涉及一种含醇醚溶剂的洗衣凝珠及其制备方法。
背景技术
洗衣凝珠是一种新型的织物洗涤产品,其内容物的活性物和传统的洗衣液类似,主要为表面活性剂,通过表面活性剂的表面活性清除污垢。洗衣凝珠和洗衣液的主要不同之处在于:(1)活性物含量一般在45%以上,比普通洗衣液高得多,属于超浓缩产品;(2)其内容物包裹封闭在呈一定几何形状水溶性薄膜里,方便计量和洗涤操作,同时也呈现出新颖的外观;(3)为适应外包水溶膜,洗衣凝珠内容物的配方必须是有机溶剂体系,不能采用传统洗衣液的水溶剂体系配方。
目前,洗衣凝珠使用的溶剂主要为丙二醇、甘油及山梨醇等,这些溶剂对于清洁去污来说是惰性的,对提高洗衣凝珠的去污力基本没有什么作用。

实验例
参照GB/T13174-2008规定测定;将实验所需的各种污布裁成6cm×6cm的大小的试片,四片为一组。试验时用250mg/kg硬水,试样实验浓度为0.1%(标准洗衣液实验浓度为0.2%),以恒温30℃且固定转速120r/min持续20min后停止,漂洗二次后晾干,测定洗涤前后的白度值,计算出各个样品的去污力进行比较。
表1各实施例及对比例去污能力
从表1可知,实施例1~5对三种污布的去污效果均≥1,符合行标QB/T1224《衣料用液体洗涤剂》对洗衣液的去污力要求;这表明添加醇醚溶剂的洗衣凝珠是完全符合洗衣液的去污力标准的,可以满足用户对衣物清洁去污的需要。
实施例1、实施例2和实施例3,它们配方大体相同,不同之处在于:(1)实施例1和实施例2使用相同的醇醚溶剂,但添加量有差别;(2)实施例1和实施例3的醇醚溶剂添加量一样,但使用不同的醇醚溶剂品种。从表1可知,添加醇醚溶剂比较多的实施例2的去污力要优于添加醇醚溶剂较少的实施例1,添加丙二醇丁醚的实施例3,去污力不如添加二丙二醇丁醚的实施例1。以上说明,优化醇醚溶剂的添加量及品种,可以使含醇醚溶剂的洗衣凝珠获得更佳的去污效果。
将对比例1和实施例1进行比较,两者配方基本相同,区别在于实施例1添加醇醚溶剂,对比例1不使用醇醚类溶剂;从表1可知,实施1的去污力明显高于对比例1,特别是对皮脂污布(JB-03),实施例1的去污力显著优于对比例1,这说明添加醇醚溶剂后,可以明显增强洗衣凝珠的去污能力。
对比例2也不添加醇醚溶剂,它是在对比例1的基础上,添加了脂肪酶。从表1可知,实施例1对皮脂污布的去污力比对比例2稍低一点,可认为两者对皮脂污布的去污力是基本相当的。众所周知,酶可以大幅度提高清洁剂的去污力,实施例1在不添加酶的情况向,其去污力基本达到了加酶(对比例2)的效果。酶的价格很高且配伍性不好、易失活,而醇醚溶剂价格相对低廉,基本不存在配伍性和失活的问题,因此添加醇醚溶剂的凝珠具有更好的性价比和配方稳定性。
上列详细说明是针对本发明可行实施例的具体说明,以上实施例并非用以限制本发明的专利范围,凡未脱离本发明所为的等效实施或变更,均应包含于本案的专利范围中。
