Description
技术领域
本发明涉及一种洗涤剂，尤其涉及一种腔膜稳定的单腔或多腔包装的液体洗涤剂。
背景技术
随着生活水平的提高，消费者对日化产品的便利性要求逐渐提高。普通的洗涤剂成品均为袋装、瓶装或罐装形式，不具备定量、轻便的性能。为此，市面上出现了单腔或多腔包装的液体洗涤剂，通常由聚乙烯醇(PVA)水溶膜作为腔膜包裹洗涤剂构成，洗涤剂为浓缩洗涤剂，一次洗涤使用一粒，轻松方便。可是，由于腔膜是由PVA或者主要成分是PVA构成，遇水会溶解，同样也能溶解在表面活性剂溶液中，为提高产品的稳定性，通常需要添加特定成分使洗涤剂与腔膜稳定共存。
发明内容
本发明的目的在于提供一种腔膜稳定的单腔或多腔包装的液体洗涤剂，该洗涤剂的PVA水溶膜能与其包装的洗涤剂稳定共存。
本发明的目的是通过以下技术方案来实现的：一种腔膜稳定的单腔或多腔包装的液体洗涤剂，由聚乙烯醇(PVA)水溶膜包裹定量液体洗涤剂构成，所述液体洗涤剂包含以下质量百分比的组分，其中所述的稳定剂为一元醇，
脂肪醇聚氧乙烯醚5-50%
脂肪酸盐5-20%
助剂0-20%
一元醇5-70%
水0-15%。
所述液体洗涤剂为浓缩洗涤剂，其中的脂肪醇聚氧乙烯醚、脂肪酸盐配比需严格控制在规定范围内，其它成分可按普通浓缩洗衣液配比。所述一元醇包括但不限于乙醇、丙醇、丁醇等。
所述助剂为任何适用于液体洗涤剂的助剂均可，如丙二醇、甘油、螯合剂、荧光增白剂、抗再沉积剂。
本发明除了上述脂肪醇聚氧乙烯醚和脂肪酸盐两种表面活性剂外，还可以包含其他表面活性剂，这些表面活性剂的总含量不超出洗涤剂总质量的30%，包括阴离子表面活性剂、非离子表面活性剂和两性离子表面活性剂。阴离子表面活性剂包括但不限于脂肪醇聚氧乙烯醚硫酸盐、脂肪酸甲酯磺酸盐、磺酸盐；非离子表面活性剂包括但不限于脂肪酸甲酯乙氧基化物；两性离子表面活性剂包括但不限于甜菜碱、氧化铵。
所述液体洗涤剂还可以包含香精、酶、防腐剂和色素等常规洗涤剂添加剂，它们的添加量采用常规量即可。
本发明与现有技术相比具有以下优点：
(1) 本发明的液体洗涤剂采用一元醇作为稳定剂，提高了PVA水溶膜的稳定性。
(2) 本发明的液体洗涤剂的一元醇，pH值中性，可在任一工序添加，操作简单。
(3) 本发明的液体洗涤剂适合国产膜包装。
