Description
本发明涉及含油的淀粉颗粒,它包括能形成所述颗粒的基质的淀粉,芳香油和用于抑制所述油向淀粉颗粒表面的迁移的具有特定结构的化合物。更具体地讲,本发明涉及含油的淀粉颗粒,它包含特定的芳香油,它能够在所述淀粉颗粒与所述基质接触后向诸如织物、硬表面、毛发和皮肤的基质送递有益添加剂。
发明背景
在液体去污剂组合物中添加香料,以使这种去污剂组合物具有怡人的芳香或香味在本领域中是众所周知的。香料的存在,在使用所述去污剂组合物后为消费者提供了美学利益,并且通常被用作洗涤过的织物的清新和洁净的信号,所述织物含有怡人的香味。不过,尽管去污剂组合物本身具有较强的芳香,但只有相对少的香料香味在洗涤期间赋予织物。这主要是因为液体组合物中的香料成分在洗涤期间会很快分散和稀释在水性洗涤和漂洗用水中。因此,在洗涤过程中只有相对有限量的香料能够接触织物,大部分的香料随着洗涤溶液一起从洗衣机中排出。因此,本领域仍然需要改进将香料从去污剂组合物送递到洗涤过的织物的效力,并且增强所述香味在织物上的寿命。
类似地,本领域需要将除了香料之外的油作为有益添加剂有效送递到诸如硬表面、毛发和皮肤的基质上,从而所述油在所述基质上的寿命相对于向基质提供这种有益添加剂的常规方法而言得到显著增加。
发明概述

根据本发明的方法方面,提供了洗涤织物的方法,该方法包括让所述织物与含有有效量的本发明的含油的淀粉颗粒的水溶液接触的步骤。
还提供了制备含油的淀粉颗粒的方法,其包括以下步骤
(a)提供淀粉在水中的分散体,以形成淀粉浆;
(b)熔化有效量的有机化合物,如包括二(烷基酰胺乙基(amidoethyl))-2-聚乙氧基胺的酰胺-胺,以形成酰胺-胺熔化物;
(c)向步骤(b)的有机化合物熔化物或酰胺-胺熔化物中添加芳香油,以形成有机化合物或酰胺-胺在芳香油中的溶液;所述芳香油所合成分的计算的ClogP至少为3,所述ClogP是计算的辛醇与水分配系数;
(d)将步骤(c)的溶液添加到步骤(a)的淀粉浆;
(e)通过混合对所得到的浆进行匀浆,以形成均匀的均相混合物;和
(f)对所述均相混合物进行喷雾干燥,以形成含油的淀粉颗粒。
可用于本发明的油可以是任何油类,它在大约10℃-90℃下是液体,并且能够向织物、硬表面、毛发或皮肤提供有益添加剂。对于洗衣用途来说,优选的油类是香料,术语“香料”在本文中用于表示能散发气味的材料,它能够为织物提供怡人的香味,并且包括常用于去污剂组合物中以抵消所述组合物中的恶臭和/或为该组合物提供怡人的香味的常规材料。所述香料在环境温度下优选是液体状态的,尽管还可以使用固体香料。
本发明的芳香油包括的成分的ClogP至少为3,其中,ClogP是计算的辛醇与水分配系数。ClogP是表示香料的水溶解度或疏水性的参数。Clog P的值越高,香料的疏水性越高。分配系数的提高,提供了更高的直接性(持久的气味,缓慢地从洗涤过的织物中发出;Sina D.Escher和Esther Oliveros;A Quantitative Study of Factors That Influence theSubstantivity of Fragrance Chemicals on Laundered and Dried Fabrics;Journal of American Oil Chemist′s Society Volume 71,No.1,pages 31-40,1994)。ClogP值为3或以上的香料比ClogP值低于3的香料更有效地沉积在织物表面上(从洗衣产品中沉积)。因此,本发明的香料成分的ClogP大约为3或更高,优选超过大约3.2,且甚至更优选超过大约3.3。
业已报导了很多香料成分的ClogP,例如,可以从Daylight ChemicalInformation Systems,Inc.(Daylight CIS)Irvine,California获得的Ponoma92数据库。所述值最常见的是使用ClogP程序计算的,该程序同样可以从Daylight CIS获得。该程序还列举了通过实验确定的log P值,它是可以从Pomona数据库获得的。计算的logP(ClogP)通常是通过Hansch和Leo的分段方法确定的(A.Leo,in ComprehensiveMedicinal Chemistry,Vol.4,C.Hansch,P.G.Sammens,J.B.Taylor和C.A.Ransden,Editors,p.295 Pergamon Press,1990)。该方法基于香料成分的化学结构,并且考虑了原子的数目和类型、原子连通性和化学成键。最可靠的并且被广泛用于估计这一生理化学特性的ClogP值可用于代替在本发明中使用的实验的LogP值。有关ClogP和logP值的其他信息可以参见美国专利5,500,138。
在本发明预期使用的香料中包含诸如醛、酮、酯等的材料,它们通常被用于赋予液体和颗粒状去污剂组合物怡人的香味。天然存在的植物和动物油通常还被用作香料的成分。因此,可用于本发明的香料可以具有相对简单的组成或可以包括天然和合成化学成分的复杂混合物,它们都被预期在用于织物时提供怡人的气味或香味。用于去污剂组合物中的香料通常要进行选择,以满足气味、稳定性、价格和工业可用性的正常要求。术语“香料”在这里通常被用于表示香料本身,而不是由所述香料产生的芳香。
可在本发明中用于为上述织物、硬表面、毛发和皮肤的基质中的一种或多种提供有益添加剂的其他油类包括维生素,如维生素E(生育酚酯),改性和未改性的硅油,表面活性剂,织物柔软剂,脂肪族醇,脂肪酸,脂肪族酯等。所述油类可以直接使用或者作为任意上述油类的组合形式使用。

本发明的洗衣店去污剂组合物可以包括选自下列一组的一种表面活性剂或表面活性剂的混合物:阴离子、非离子和阳离子表面活性剂。
任何合适的非离子型去污剂化合物都可以用作本发明洗衣店去污剂组合物中的表面活性剂,所述去污剂的多种成员描述在Detergents and Emulsifiers的各种年鉴中,作者John W.McCutcheon。所述书籍提供了在美国上市的商业非离子型去污剂的化学式和商标,并且基本上所有这样的去污剂都可用于本发明组合物中。不过,高度优选的是,所述非离子型去污剂是环氧乙烷和高级脂肪族醇的缩合产物(尽管还可以使用高级脂肪酸和烷基[辛基、壬基和异辛基]苯酚替代高级脂肪族醇)。所述醇和所得缩合产物的高级酯肪部分,如烷基,正常是线性的,具有10-18个碳原子,优选10-16个碳原子,更优选12-15个碳原子,并且有时候最优选12-14个碳原子。因为所述脂肪族醇正常是以混合物形式商业出售的,所以所提供的碳原子的数目必须是平均数,但在某些场合下,碳原子数目的范围可以是所采用的醇和相应的烷基的实际限度。
所述非离子型去污剂中环氧乙烷(EtO)含量正常在每摩尔高级脂肪族醇3-15摩尔EtO的范围,尽管可以存在高达20摩尔的EtO。优选的是,所述EtO含量为3-10摩尔,且更优选为6-7摩尔,例如,每摩尔高级脂肪族醇(以及每摩尔非离子型去污剂)6.5或7摩尔。与高级脂肪族醇一样,所提供的聚乙氧基化物限度还可以限定缩合产物中存在的EtO基团数目的平均值。合适的非离子型去污剂的例子包括由ShellChemical Company以Neodol为商标出售的产品,包括Neodol 25-7、Neodol 23-6.5和Neodol 25-3。
其他有用的非离子型去污剂化合物包括烷基多苷和烷基多糖表面活性剂,这些表面活性剂是众所周知的,并且在现有文献中有广泛描述。
所述去污剂组合物可以包括线性烷基苯磺酸盐阴离子表面活性剂,其中,所述烷基自由基包括大约10-16个碳原子,是直链或支链形式的,且优选12-15个碳原子。合适的合成阴离子表面活性剂的例子是烷基(C4-C20)苯磺酸钠和钾,特别是线性仲烷基(C10-C15)苯磺酸钠。
在本发明液体去污剂组合物中任选包括的其他合适的阴离子型去污剂是硫酸化乙氧基化高级脂肪族醇,其具有式:RO(C2H4O)mSO3M,其中,R是10-18个碳原子的脂肪烷基,m是2-6(优选具有R中碳原子数目的大约1/5-1/2的值),而M是增溶性形成盐的阳离子,如碱金属、铵或高级烷基苯磺酸盐,其中,所述高级烷基具有10-15个碳原子。环氧乙烷在聚乙氧基化高级硫酸链烷醇酯中的比例通常为1-11个环氧乙烷基团,且优选2-5摩尔环氧乙烷/摩尔阴离子型去污剂,最优选3摩尔,尤其是当高级链烷醇具有11-15个碳原子时。
最优选的水溶性阴离子型去污剂化合物是高级烷基苯磺酸,和高级烷基硫酸的铵和取代过的铵(如一、二和三乙醇胺)、碱金属(如钠和钾)和碱土金属(如钙和镁)盐。
助洗剂材料是本发明液体去污组合物的基本成分。具体地讲,大约2%-大约15%的碱金属碳酸盐,如碳酸钠,且优选按重量计大约3%-大约10%。
按重量计大约5%-大约30%量的磷酸盐助洗剂,且具体是碱金属(钠)多磷酸盐是本发明液体去污组合物的组成成分。所述多磷酸盐助洗剂的量优选为大约8%-大约20%。
合适的含磷无机去污助洗剂的例子包括水溶性盐,尤其是碱金属焦磷酸盐、正磷酸盐和多磷酸盐。无机磷酸盐助洗剂的具体例子包括三多磷酸、磷酸和六偏磷酸钠和钾。
在本发明的组合物中可任选地包括沸石A型的硅铝酸盐助洗剂,它通常是水合的。还可以使用水合沸石X和Y,也可使用起着去污助洗剂作用的天然存在的沸石。在各种沸石A产品中,沸石4A通常是优选的,它是一种类型的沸石分子,其中,孔径大小为大约4。这种类型的沸石在本领域是众所周知的,并且它的生产方法描述于诸如美国专利3,114,603的本领域中。
所述沸石助洗剂通常具有式
(Na2O)x·(Al2O3)y·(SiO2)z·wH2O
其中,x是1,y是0.8-1.2,优选大约1,z是1.5-3.5,优选2或3或大约2,而w是0-9,优选2.5-6。本发明可以使用的沸石的晶体类型包括在以下文献中所描述的那些:“Zeolite Molecular Series”,DonaldBreck著,由John Wiley & Sons于1974年出版,一般的商业化沸石在该文献的第747-749页上的表9.6中列举,该表被收作本文参考。
所述沸石助洗剂应当是一价阳离子交换沸石,即它应当是一价阳离子的硅铝酸盐,如钠、钾、锂(在可应用时)或其他碱金属或铵。具有碱金属阳离子,尤其是钠的沸石是最优选的,正如在上面的式中所示出的。所采用的沸石的特征是具有对钙离子的高的交换能力,通常为每克硅铝酸盐具有大约200-400或以上毫克当量的碳酸钙硬度,优选250-350mg.eg./g.,它是以无水沸石为基础计算的。沸石的优选量为大约8%-大约20%。
在去污剂组合物中可以存在其他成分,以改善其特性,并且,在某些场合下,起着稀释剂或填料的作用。合适的佐剂的说明性例子有酶,以进一步促进从衣物或硬表面清洗某些难以去除的污渍。在所述酶中,最有用的是蛋白酶和淀粉分解酶。其他有用的佐剂是当需要泡沫时的起泡剂,如月桂酸肉豆蔻酸二乙醇酰胺,和当需要时的防沫剂如二甲基硅氧烷流体。同样有用的是聚合物,抗再沉积剂,漂白剂,荧光增白剂,如均二苯代乙烯增白剂,着色剂,如染料和色素和香料。
分析方法
1.干燥织物的加热的SPME顶空分析
固相微量萃取(SPME;Almirall,J.R.;Furton,K.G.In Solid PhaseMicroextraction;A Practical Guide;Scheppers-Wercinski,S.,Ed;MarcelDekker;New York,1999,pp.203-216)是无溶剂的萃取技术,通过这种技术将分析物从基质(如织物)上萃取到聚合物或其他相中,涂敷在熔融的二氧化硅纤维上。SPME与气相层析(GC)偶联,用于对分析物进行解吸和分析。

2.厚绒布毛巾的反萃取方法
对所有样品评估来说,在17加仑顶部加载洗衣机中准备24条新的厚绒布手巾(86%棉,14%聚酯),设定为热洗(120),使用自来水,采用超大设定。两轮洗涤使用100g无香料的Mexican Viva 2去污剂粉,一次洗涤只使用水,打开额外漂洗开关,将以上方法用于所有洗涤。在所有三个洗涤循环结束之后,在电子衣物干燥器中对所述毛巾进行干燥机干燥,并且平放进行贮存。对用于测试的所有衣物压载物在每一次使用之间以与毛巾相同的方式处理。

淀粉颗粒
淀粉/AA.颗粒是使用Capsul淀粉(由National Starch出售的产品)制备的。Capsul是糊精化的蜡质种玉米辛烯基琥珀酸淀粉。所述降解淀粉的糊精化过程使Capsul淀粉与其他类型的淀粉区分开。利用下述方法制备淀粉/AA颗粒:至少提前一天用GREERCO Model No.1L混合器在水中预混合33%Capsul淀粉。让空气沉降出来。从中取出需要的量,并且添加芳香油和熔化的酰胺-胺混合物,并且使用Silverson Model L4R混合器匀浆。将该混合物倒入Armfield FT80 Tall Form喷雾干燥器(Spray Dryer)中,并且在190℃下进行喷雾干燥,采用0.5-1.0巴的雾化压力。

研究表明,疏水性添加剂AA能显著减少干燥的淀粉胶囊表面上的香料量(Dinasty主要香料),从2.89%(无AA)降低到0.24%(表3)。与AA相反,另一项研究表明,疏水性改性的二氧化硅(Aerosil R974;现有技术中的优选添加剂,专利申请WO01/05926)不能将表面油的量降低到与酰胺-胺相同的程度(表3)。Aerosil能将淀粉颗粒上的表面油(Dinasty香料)的量从3.09%(无Aerosil)降低到2.38%(有Aerosil)。表面油是通过以下方法测量的:在室温和大气压力下用己烷从被囊化颗粒中萃取,然后进行气相层析。己烷只能萃取颗粒表面的芳香油,而不能萃取颗粒内被囊化的油。
