Abstract
本发明涉及一种粉液型洗衣凝珠,所述粉液型洗衣凝珠包括粉体腔和液体腔;本发明制得的粉液型洗衣凝珠在使用过程中,当PVA薄膜完全溶解后,过碳酸盐遇水可以快速释放出活性氧,活性氧能使有机色素与纤维结合的化学键断裂,使污渍氧化分解成可溶于水的小分子,达到容易清洗的效果;我们还意外的发现,通过螯合剂、过碳酸盐、烷基吡咯烷酮三者协同作用,能够协同明显提高对污渍的去除能力;螯合剂可以对过碳酸盐起到很好的稳定性作用,大大降低粉液洗衣凝珠中过碳酸钠的活氧释放速度,保留了产品长期的活氧洗涤能力。
Description
技术领域
本发明涉及织物洗涤护理技术领域,特别是涉及一种粉液型洗衣凝珠及其制备方法。
背景技术
随着社会的发展及人民生活水平的提高,洗涤剂的剂型也在不断改变及丰富。从最开始的皂到洗衣粉,再从洗衣粉市场占有率不断减少,液体类洗涤剂逐渐增多。而如今,据最新的洗涤剂市场调研发现,洗衣凝珠呈现了更加惊人的市场增长率。尽管如此,市场上粉体类洗涤产品依然占据较大的市场份额,原因是不同消费群体对不同剂型洗涤产品的喜爱,同时也表明粉体剂型洗涤剂产品在某些方面的不可替代性。
洗衣凝珠增速较快及受消费者欢迎的原因包括产品本身的浓缩性、多功能性、产品外观的美观以及对衣物的损害等方面。尽管如此,但洗衣凝珠仍然存在一些缺陷,如难以添加漂白类原料,如过氧化物、次氯酸盐等。在清洁方面的体现是难以清洁部分色素类污渍。因此,粉液型洗衣凝珠不仅可以具有上述纯液洗衣凝珠优点,还可以添加更稳定及安全的漂白类原料,保留粉体物料的优良性能。
对于粉液型洗衣凝珠而言,液体腔原料可以选择常规的表面活性剂、有机溶剂、助剂进行配制,粉体腔原料可以选择过氧化物颗粒、皂粉或其他固体类表活及助剂进行配制。利用洗衣凝珠设备封装成粉液洗衣凝珠。例如通过上述方法使用过氧化物颗粒作为粉体腔物料制备成粉液型洗衣凝珠虽然可以对更广泛的污渍类型起到清洁效果,但是限于洗衣凝珠腔体装载量的大小(洗衣凝珠装载量一般不超过20g)、过氧化物的含量及有效作用率等因素。因此去除效果偏弱,甚至部分洗衣凝珠市售商品在JB01、JB02、JB03三种国标污布的去污无法达到规定要求,与纯液型洗衣凝珠相比没有明显的技术进步。另外,如果选用高含量表面活性剂粉体物料作为粉体腔制备成粉液洗衣凝珠,虽然可以满足国标污布的去污,但是鉴于高含量表面活性剂颗粒的流动性与干爽度,在生产时容易发生难以下料或出料不匀的现象。
综上所述,亟须研究开发一种粉液型洗衣凝珠技术方案,以解决现有技术中存在的问题。
发明内容
基于此,本发明提供了一种粉液型洗衣凝珠,以克服现有技术的不足。该技术方案适合稳定安全的、具有漂白性功能的粉液型洗衣凝珠。该洗衣凝珠产品通过利用粉液不同形式的助剂促进活氧原料的分解及织物渗透以最大程度发挥活氧的清洗功能。
本发明的一个目的在于,提供一种粉液型洗衣凝珠,所述粉液型洗衣凝珠包括粉体腔和液体腔;
所述粉体腔中包括粉体;所述液体腔中包括浓缩液;
所述粉体包括质量分数如下的组分:
其中,
所述粉体和所述浓缩液的质量比为1:1-4:1;
所述螯合剂具有以下结构通式:
所述R选自H、Na、K中的一种;
优选地,所述R为Na。
在高温碱性环境下,螯合剂可以络合催化漂白过程中产生的沉积物,使清洁效果进一步提高,降低碳酸型、硅酸型污垢的产生。
所述烷基吡咯烷酮具有以下结构通式:
所述R1选自碳原子数为6-16的烷基,或者碳原子数为6-16的烷基衍生物;
优选地,所述烷基吡咯烷酮选自辛基吡咯烷酮、十二烷基吡咯烷酮中的一种或多种;
更优选地,所述烷基吡咯烷酮为辛基吡咯烷酮。
优选地,所述粉体包括质量分数如下的组分:
螯合剂2-15%
过碳酸盐60-90%
洗涤助剂A 5-30%;
所述浓缩液包括质量分数如下的组分:

优选地,所述包衣型过碳酸盐为包衣型过碳酸钠。
由于采用包衣型过碳酸盐遇水可以快速释放出活性氧,活性氧能使有机色素与纤维结合的化学键断裂,使污渍氧化分解成可溶于水的小分子,达到容易清洗的效果,包衣型过碳酸盐可以作为粉体主要原料结合浓缩液体组合物制备成粉液型洗衣凝珠,可用于顽固色素类污渍去除及泛黄漂白等问题。

进一步地,所述有机溶剂选自乙醇、甘油、丙二醇、山梨醇、聚乙二醇、二乙二醇丁醚、二丙二醇甲醚、三丙二醇甲醚、二乙二醇丁醚醋酸酯、二丙二醇丁醚和三丙二醇丁醚中的一种或多种。
本发明还提供了粉液型洗衣凝珠的制备方法,包括如下步骤:
S1.将螯合剂、过碳酸盐、洗涤助剂A进行混合,得到粉体;
S2.将水、烷基吡咯烷酮、碱性中和剂、表面活性剂、洗涤助剂B、有机溶剂进行混合,搅拌均匀,得到浓缩液;
S3.将所述粉体、所述浓缩液进行分腔包裹形成粉体腔和液体腔,得到粉液型洗衣凝珠。
进一步地,步骤S2中,还包括如下步骤:
(1).将碱性中和剂加入水中,搅拌至溶解完全;
(2).再加入部分的有机溶剂,搅拌至溶解完全;
(3).加入磺酸、饱和脂肪酸,调节pH至中性,搅拌溶解;
(4).加入其他表面活性剂、烷基吡咯烷酮、洗涤助剂B,并加入余量的有机溶剂,搅拌至外观均一,得到浓缩液。
本发明具有以下有益效果:
1.本发明制得的粉液型洗衣凝珠在使用过程中,当PVA薄膜完全溶解后,过碳酸盐遇水可以快速释放出活性氧,活性氧能使有机色素与纤维结合的化学键断裂,使污渍氧化分解成可溶于水的小分子,达到容易清洗的效果。我们意外发现螯合剂、过碳酸盐、烷基吡咯烷酮三者能够协同明显提高对污渍的去除能力,这是由于烷基吡咯烷酮具有五元环内酰胺结构有利于提高其对纤维的渗透和润湿,并且其渗透与润湿性能随着烷基碳数的变化而不同。本发明中烷基吡咯烷酮有利于过碳酸盐分解后释放的活性氧渗透到纤维内部,同时过碳酸盐在活性氧发挥作用时会分解的碳酸根离子,和水中的钙镁离子会形成沉积物,而螯合剂会和沉积物进行络合,降低碳酸垢的形成,进一步增强了去污效果。
2.由于螯合剂对过碳酸盐起到很好的稳定性作用,大大降低粉液洗衣凝珠中过碳酸钠的活氧释放速度,保留了产品长期的活氧洗涤能力,而且液体腔中的烷基吡咯烷酮溶入水后,会进一步增强洗衣凝珠中活氧的渗透能力,明显提高对污渍的去除能力,使得洗衣凝珠既具有优异的去污能力,又具有较强稳定性。

基于实施例2设置对比例1-3,对比例1-3的成分和质量分数,如表2所示。
表2对比例1-3中各成分及其质量分数
对比例与实施例2的区别在于:对比例1将螯合剂IDS-Na4替换为等质量的4A沸石;对比例2将包衣型过碳酸钠SPCC替换为等质量的混合型过碳酸钠SPC;对比例3将烷基吡咯烷酮LP-100替换为等质量的渗透剂JFC,其他成分和制备方法相同。
测试例
一、稳定性测试
测试方法:
高温稳定性:分别将实施例2和对比例1-3制备的粉液型洗衣凝珠组合物瓶装密封后,置于45℃环境,恒温放置1个月后,恢复至室温25℃,组合物外观无显著变化,粉体腔无变色、结块,液体腔无分层、浑浊、凝胶或沉淀析出,包裹水溶膜无破损,为高温稳定性合格。
低温稳定性:分别将实施例2和对比例1-3制备的粉液型洗衣凝珠组合物瓶装密封后,置于0℃环境,恒温放置1个月后,取出立即观察。洗衣凝珠外观无显著变化,粉体腔无结块,液体腔无分层、浑浊、凝胶或沉淀析出,包裹水溶膜无破损,为低温稳定性合格。
常温稳定性:分别将实施例2和对比例1-3制备的粉液型洗衣凝珠组合物瓶装密封后,置于室温环境(25℃),放置1个月后,粉体腔无变色、结块,液体腔无分层、浑浊、凝胶或沉淀析出,包裹水溶膜无破损,为常温稳定性合格。
稳定性测试结果如表3所示:
表3实施例2、对比例1-3粉液型洗衣凝珠的稳定性测试结果
测试结果表明,实施例2的洗衣凝珠在各个测试温度下能保证样品的稳定性,对比例1-3的洗衣凝珠稳定性较差,这是由于在对比例1中粉体腔使用4A沸石代替IDS-Na4,由于4A沸石本身特殊的多孔网络状结构使其具备较强吸附能力,加速了水溶膜与外部物质的传递与交换能力,导致洗衣凝珠的水溶膜表面轻微泛白。在对比例2中,使用非包裹型的过碳酸钠SPC代替包裹型SPCC,由于非包裹型SPC本身储存稳定性较差,储存过程中更容易释放出活性氧,而活性氧是可以渗透到液体腔中,造成液体腔变黄。在对比例3中,由于液体腔中使用渗透剂JFC,因此对液体腔中液体组合稳定性造成影响,在高温稳定性、低温稳定性液体腔出现微雾浊现象。
二、国际污布去污力测试:
去污测试方法为:对实施例2和对比例1-3制备的粉液型洗衣凝珠组合物参照《GB/T 131742008衣料用洗涤剂去污力及循环洗涤性能的测定》进行去污力测试。在去污测试中,标准洗衣液和实施例2和对比例1-3制备的粉液型洗衣凝珠组合物采用不同测试浓度,从而确保样品中的实际添加表面活性剂的实际含量接近。
其中,JB01为碳黑油污布;JB02为蛋白污布;JB03为皮脂污布。
测试结果如表4所示,其中P值代表去污比值。一般地,以标准洗衣液作为参比样,其去污比值设定为1.00;P值越高,表明清洁力越好。
表4实施例2和对比例1-3的洗衣凝珠和标准洗衣液的去污测试结果
从表4中可以看出,实施例2中的洗衣凝珠对炭黑、蛋白、皮脂的去污效果明显优于标准洗衣液,尤其碳黑、皮脂方面表现更为明显。其中,蛋白污布主要受蛋白酶、表活含量影响较大。对比例1由于将螯合剂IDS-Na4替换为等质量的4A沸石,因此与包衣型过碳酸钠SPCC的清洁力无法产生明显协同增效作用,导致碳黑污布方面的去污能力下降。而对比例2由于将包衣型过碳酸钠SPCC替换为等质量的非包衣型过碳酸钠SPC,较大程度上影响了在碳黑与皮脂方面的去污力。对比例3将烷基吡咯烷酮LP-100替换为渗透剂JFC,对三种污布的去污效果均有负面影响。
三、实际污布去污力测试:
去污测试方法为:对实施例2和对比例1-3制备的粉液型洗衣凝珠组合物参照《GB/T 131742008衣料用洗涤剂去污力及循环洗涤性能的测定》进行去污力测试。在去污测试中,标准洗衣液和实施例2和对比例1-3制备的粉液型洗衣凝珠组合物采用不同测试浓度,从而确保样品中的实际添加表面活性剂的实际含量接近。
其中,污布替换为技术研究人员自己制作的实际污布,实际污布分别为YK01为青草咖啡污布、YK02为巧克力碘伏污布、YK03为酱油红茶污布。
所述YK01青草咖啡污布的制备方法为:①使用小青草压榨液与雀巢咖啡按照质量比1:1混合,然后加水,制备成100g/L的混合污液;②将针织棉布按照1:20浴比进行常温浸渍,浸渍时间为10min;③使用轧车对浸渍后的污布进行压轧,使其带液率为1:1,晾干,裁剪成6cm*6cm污布备用。
所述YK02巧克力碘伏污布的制备方法为:①将20g德芙巧克力加入70℃的1L水中进行溶解,制备成20g/L的污液;②将①制备的污液与1g/L的碘伏进行质量比1:1混合制备成污液;③将针织棉布按照1:20浴比进行常温浸渍,浸渍时间为10min;④使用轧车对浸渍后的污布进行压轧,使其带液率为1:1,晾干,裁剪成6cm*6cm污布备用。
所述YK03酱油红茶污布的制备方法为:①将5g红茶加入到1L水中,煮沸、过滤;②将①中制备的污液与海天酱油按照质量比2:1混合制备成污液;③将针织棉布按照1:20浴比进行常温浸渍,浸渍时间为10min;④使用轧车对浸渍后的污布进行压轧,使其带液率为1:1,晾干,裁剪成6cm*6cm污布备用。
测试结果如表5所示,其中P值代表去污比值。一般地,以标准洗衣液作为参比样,其去污比值设定为1.00;P值越高,表明清洁力越好。
表5实施例2和对比例1-3的洗衣凝珠和标准洗衣液的去污测试结果
包衣型过碳酸钠SPCC在溶解过程中会产生活性氧,而活性氧可以使很多污渍发生分解,从而发挥清洁作用;本测试中多种对活性氧敏感的污渍,如咖啡、巧克力、红茶、碘伏等。
从表5中可以看出,实施例2中的洗衣凝珠对青草咖啡、巧克力碘伏、酱油红茶的去污效果优于标准洗衣液。其中,对比例1将由于将螯合剂IDS-Na4替换为等质量的4A沸石,对比例2将包衣型过碳酸钠SPCC替换为等质量的非包衣型过碳酸钠SPC,对比例3烷基吡咯烷酮LP-100替换为渗透剂JFC,可见,对比例1、3包衣型过碳酸钠SPCC的功效受到影响,去污力下降,而对比例2中由于将包衣型过碳酸钠SPCC替换了为非包衣型过碳酸钠SPC,使得洗衣凝珠对咖啡、巧克力、茶渍等污渍的去除难度增加。
对于本领域技术人员而言,显然本发明不限于上述示范性实施例的细节,而且在不背离本发明的精神或基本特征的情况下,能够以其他的具体形式实现本发明。因此,无论从哪一点来看,均应将实施例看作是示范性的,而且是非限制性的,本发明的范围由所附权利要求而不是上述说明限定,因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。
