Abstract
许多患有肛门直肠不适与障碍的人需要用于改善清洁,但不会过度刺激皮肤的预先以溶液湿润的纤维状薄片材料。尤其是,本发明涉及包含含有金缕梅属水或金缕梅的溶液以有效地治疗肛门直肠障碍的湿擦拭物(比如肛门直肠擦拭物)。
Description
技术领域
本发明涉及预先以用于改善清洁,但不会过度刺激皮肤的溶液润湿的纤维状薄片材料(fibroussheetmaterial)。尤其是,本发明涉及包含金缕梅属(hamamelis)水或金缕梅(witchhazel)的湿擦拭物(wetwipe),比如肛门直肠擦拭物,其适合用于女性肛门直肠和会阴区。此湿擦拭物应包含有效的清洁液,但也为非刺激性且传递清新的感觉和气味。
背景技术
湿擦拭物是众所周知的消费性商品,其可以多种形式获得。或许最常见的湿擦拭物形式是已经包装在塑料容器中的一叠润湿的薄片。湿擦拭物是由各种已经以各种合适的擦拭溶液润湿的材料制造的。典型地,湿擦拭物可以折叠或未折叠构形获得。例如,已可获得其中在擦拭物堆叠中的各湿擦拭物是以折叠构形安排(比如本领域技术人员所熟知的c型折叠构形、z型折叠构形或四分之一型折叠构形)的湿擦拭物叠。各折叠的湿擦拭物也与该叠湿擦拭物中紧接在其上和其下的湿擦拭物交错折叠。在替代的构形中,湿擦拭物为连续材料卷(webofmaterial)的形式,该材料卷包括穿孔以分开单个湿擦拭物且该单个湿擦拭物卷绕成卷,并包装在塑料容器中。这类湿擦拭物已经用于婴儿擦拭物、手部擦拭物、家庭清洁擦拭物、工业擦拭物。
被纳入传统湿擦拭物中的溶液通常包括一些意在增强或赋予该擦拭物特殊性质的成分。这些性质与,例如清洁效力、香料、药物、降低刺激性、皮肤健康、产品的美观性等有关。在婴儿擦拭物方面,提供轻柔舒缓感觉而无过度刺激性或泡沫,同时保持清洁及抗微生物效力的溶液对产品性能是高度希望的。用于提供这样的性质的合适成分已经包括水、软化剂、表面活性剂、防腐剂、螯合剂、pH缓冲剂或其组合。该溶液也含有洗剂和/或药物。
然而,用于湿擦拭物的传统溶液和,尤其是,在这样的溶液中的表面活性剂尚未完全令人满意。例如,为了降低皮肤刺激的程度,传统的湿擦拭物溶液已经包括两性表面活性剂,其通常导致很少或不会引起皮肤刺激。这样的两性表面活性剂已经包括椰油酰两性乙酸钠和椰油酰两性二乙酸二钠。然而,这样的两性表面活性剂典型地不会表现出与其他表面活性剂(比如阴离子表面活性剂)相关的高水平的清洁效力。这样的两性表面活性剂一典型地也不提供消费者,尤其是女性消费者的皮肤所需要的最理想的柔滑感。
另一方面,阴离子表面活性剂虽然表现出这样的清洁效力,其典型地会造成过度的皮肤刺激,比如干燥和脱皮,因此不适合用于湿擦拭物应用中。在女性肛门直肠及会阴区的用药中,由于阴道和肛门皮肤柔软,由这样的表面活性剂所引起的高度皮肤刺激特别不希望的。此外,由于阴离子表面活性剂高度起泡和去污活性,大多数阴离子表面活性剂适合用于洗涤剂组成物。然而,这类起泡在湿擦拭物中的应用通常是不希望的,尤其是在肛门直肠药物擦拭应用中。使用湿擦拭物的消费者更喜欢来自湿擦拭物的溶液不在皮肤表面上遗留任何皂类或多泡的残留,因为使用湿擦拭物后通常不会擦掉留在皮肤上的溶液。
在女性肛门直肠和会阴区药物擦拭物方面,提供轻柔舒缓感觉而无过度刺激性或泡沫,同时保持清洁及抗微生物效力的溶液对产品性能是非常希望的。婴儿擦拭物更需要温和而有效的清洁,而本发明中公开的新颖擦拭物是设计成不仅温和且有效清洁,而且还舒缓。
因此,提供用于湿擦拭物的包括显示出改善的清洁效力,同时不会引起过度的皮肤刺激或起泡的表面活性剂的溶液仍是希望的。
使用专门设计用来清洁女性肛门直肠和会阴区的脆弱而敏感的皮肤的表面活性剂是高度希望的。甜菜碱类的表面活性剂是希望的,因为它们提供有效的清洁,通常不会起泡且以其温和的特性闻名。
发明内容
响应上文所讨论的困难和问题,现已发现具有用于应用于女性肛门直肠和会阴区的改善的溶液的新的湿擦拭物。
一方面,本发明涉及包含纤维状薄片材料和非油性的基于水性的(aqueous-based)溶液的湿擦拭物,该非油性的基于水性的溶液包含:
a)约10至约50%的金缕梅;
b)约0.01至约2%的至少一种乳化剂;及
c)约0.01至约0.20%的至少一种软化剂;
其中该重量百分比基于所述溶液的总重量。
另一方面,本发明涉及包含纤维状薄片材料和非油性的基于水性的溶液的湿擦拭物,该非油性的基于水性的溶液包含:
a.)约20重量%的金缕梅;
b.)约9重量%的甘油;
c.)约5重量%的丙二醇;
d.)约1.5重量%的乙氧基化的牛油树脂;

p.)约0.05重量%的对羟基苯甲酸丙酯;
q.)约63重量%的添加的纯水;
其中重量百分比基于所述溶液的总重量。
再另一方面,本发明涉及使用根据上述湿擦拭物来制造湿擦拭物的方法,其包括使用具有包含在其上的溶液的湿擦拭物来擦拭人的皮肤并通过使用该湿擦拭物使溶液在擦拭完成后留存在人的皮肤上。
在本发明的各种方面中,有利的是,本发明涉及用于应用于女性肛门直肠和会阴区的湿擦拭物,当与传统的湿擦拭物相比较时,其具有改善的清洁效力,而无过度的皮肤刺激或起泡,且传递清新感和气味。另外,本发明提供用于湿擦拭物的溶液,其在应用期间和应用后留给皮肤光滑、柔滑的感觉。
发明详述
本发明涉及具有多组分保存系统的纤维材料,尤其是湿擦拭物,其适合用于肛门/肛周区域的多次使用包装的产品。该湿擦拭物包含温和的表面活性剂,以促进清洁并舒缓受刺激的区域,且适合用于可能受刺激的肛周组织。本发明的湿擦拭物可用于肛门直肠障碍,比如痔疮等。这样的湿擦拭物通常被折叠并以堆叠构形在供售于消费者的合适的容器内。
适合用于这样的湿擦拭物的材料是本领域技术人员所熟知。该湿擦拭物典型地是由织造或非织造的纤维状薄片材料制造。例如,本发明的湿擦拭物可包括非织造纤维状薄片材料,此非织造纤维状薄片材料包括熔喷(meltblown)、共成形(coform)、气流铺置(air-laid)、黏合梳理纤网(bonded-cardedweb)材料、水刺(hydro-entangled)材料、其组合等。这样的材料可包含合成或天然纤维、或其组合。典型地,该湿擦拭物限定每平方米约25至约120克的基础重量,且希望地为每平方米约40至约90克。
本发明的湿擦拭物可包含聚合性微纤维和纤维素纤维的共成形基片(basesheet),其具有每平方米约60至约80克的基础重量,其希望地为每平方米约75克。这样的共成形基片通常是如1978年7月11日出版的授让予Anderson等人的美国专利第4,100,324号(其以引用方式被并入本文)中的描述制造。经典地,这类共成形基片包含热塑性聚合性熔喷微纤维(比如,例如聚丙烯微纤维)和纤维素纤维(比如,例如木浆纤维)的气体成形基质。
最优选地,本发明的湿擦拭物是市售GreenBay,Wisconsin的AhlstromGreenBayInc.的Grade非织造材料。
可选地,本发明的湿擦拭物可包含包括多层材料的复合材料(composite)。例如,该湿擦拭物可包括3层复合材料,此3层复合材料包括介于如上述两共成形层之间的弹性体膜或熔喷层。在这样的构形中,该共成形层可限定每平方米约15至约30克的基础重量,且该弹性体层可包括膜材料,比如聚乙烯茂金属(metallocene)膜。
单个湿擦拭物通常是以折叠构形排列。这样的折叠构形为本领域技术人员所熟知,且包括c形折叠、z形折叠及四分之一折叠构形等。各湿擦拭物也可与该叠湿擦拭物中紧接在其上和其下的湿擦拭物交错折叠。该湿擦拭物通常限定展开的宽度和展开的长度。该湿擦拭物可具有任何合适的展开的宽度和长度。例如,该湿擦拭物可具有约2.0至约80.0厘米的展开的长度,和约2.0至约80.0厘米的展开的宽度。
本发明的不同方面的湿擦拭物也含有被吸收入该湿擦拭物中的溶液。包含在各湿擦拭物内的溶液的量可根据所使用的提供该湿擦拭物的材料类型、所使用的溶液类型、用于储存该湿擦拭物的容器类型和希望地该湿擦拭物的最终用途而变化。一般而言,各湿擦拭物可基于该擦拭物的干燥重量含有约150至约600重量%的溶液,希望约250至约450重量%的溶液,以用于改善擦拭。
在本发明的一个方面中,该湿擦拭物是在塑料容器中包装成叠。在这样的容器中,优选的溶液对擦拭物的干燥重量比为约3.5:1至约4.5:1,更优选为约3.8:1至约4.3:1且最优选为约4:1的溶液对擦拭物(基于所述湿擦拭物的干燥重量)。若该溶液的量少于上述限定范围,该湿擦拭物可能太干且可能无法充分地进行。若该溶液的量大于上述限定范围,该湿擦拭物可能会过饱和且湿透,而该溶液可能汇集在容器的底部。
在一个特殊的方面中,其中该湿擦拭物被单个包装在铝箔袋中,该溶液对擦拭物的干燥重量的优选比例为约3.5:1至约6:1,更优选为约3.5:1至约5.2:1且最优选为约4.7:1的溶液对擦拭物(基于所述湿擦拭物的干燥重量)。
在本发明的湿擦拭物中的溶液包含金缕梅,此为有效的清洁剂且为本发明的溶液提供舒缓、凉感和独特的香味。存在于该溶液中的金缕梅的量在约10至约50%的范围内变化,更优选为在约10至约20%的范围内变化,最优选为约20%(基于溶液的总重量)。在一特殊的实施方式中,本发明包含购自AmericanDistillingInc.且具有14%的酒精含量的金缕梅(witchhazel)或金缕梅属(hamamelis)水作为合适的清洁剂。
为了提供改善的触觉性质和清洁效力,但无过多起泡或皮肤刺激,本发明的湿擦拭物中的溶液包含两性或兼性离子(zwitterionic)表面活性剂。兼性离子的甜菜碱家族具有三甲基甘氨酸(甜菜碱)(源自甜菜根的氨基酸)的阳性-阴性头基结构。该疏水性尾基可为直链烷基(比如在椰油基甜菜碱(cocobetaine)中)或可含有酰胺基,比如椰油酰氨丙基甜菜碱。其他甜菜碱包括月桂酰氨丙基甜菜碱、油酰氨丙基甜菜碱、蓖麻油酰氨丙基甜菜碱、十六烷基甜菜碱和二聚亚油酰氨丙基甜菜碱。另外的变体为磺基甜菜碱碱、羟磺基甜菜碱和磺基甜菜碱(sultaine)。经由加入盐类,甜菜碱比其阴离子同类(cousin)更能抵抗增稠。为此,为了取得令人合意的浓稠产品,添加黏度加强聚合性添加剂可能是必要的,这可能增加成本及配方的复杂性(见http://www.naturallycurly.com/curlreading/ingredients/zwitterionic-surfactants-a-milder-alternative)。
为了提供本发明的湿擦拭物中改善的触感和清洁性质但无过量起泡或皮肤刺激,本发明的溶液包含至少一种表面活性剂,优选为甜菜碱表面活性剂。该溶液可包括任何量的能提供希望性质的甜菜碱表面活性剂。所选择的特定甜菜碱可对最终产品的黏性、起泡行为和去污性具有显著影响。在一个特殊的实施方式中,该溶液包括约0.01至约10重量%,希望地为约0.01至约5重量%的甜菜碱表面活性剂(基于该溶液的总重量)。最优选地,本发明包含范围为约0.1w/w%的商购自EvnoikDegussa,商品名为TegoBetaine的辛酰/癸酰氨丙基甜菜碱(基于该溶液的总重量)。具有低于优选的表面活性剂重量百分比的比率的溶液可能因为不希望的触觉性质(比如黏性和触摸后失去柔滑)、去污活性降低和皮肤刺激增加而是不希望的。
包含在本发明的湿擦拭物内的溶液的pH值限定为约5至约7,希望地为约5至约6。低于约5的pH值水平通常是不希望的,因为可能刺激皮肤。然而,高于约7的pH水平也是不希望的,因为可能危及防腐活性并可能导致皮肤刺激。可使用相对量的合适的缓冲剂(比如柠檬酸及柠檬酸钠),以取得希望的pH值。本发明的溶液包含约为所述溶液的约0.05至约0.25重量%的缓冲系统。
该溶液也可包含各种可协助提供希望的擦拭和清洁性质的其他组分。例如,该组分可包括水、软化剂、至少一种表面活性剂、至少一种防腐剂,至少一种螯合剂、至少一种pH缓冲剂、至少一种香料或其组合。该溶液也可含有至少一种洗剂和/或药物。为了降低皮肤刺激,希望地该溶液包含至少约30重量%至约80重量%的添加的纯水(基于该溶液的总重量),更优选为约63重量%的添加的纯水(基于该溶液的总重量)。
例如,该溶液可包括有效量的至少一种防腐剂,以抑制微生物生长。合适的防腐剂为本领域技术人员所熟知,且包括,例如对羟基苯甲酸酯、羟甲基甘氨酸钠、有机酸(比如苯甲酸和苹果酸)、DMDM乙内酰脲(DMDMhydantoin)等及其组合。在一个特殊的实施方式中,该抗微生物防腐剂包含对羟基苯甲酸甲酯、对羟基苯甲酸丙酯和购自ISPTechnologies,Inc,商品名为GERMALLⅡ的二偶氮烷基脲(diazolidinylurea)。该溶液可包括任何量的能提供希望抗微生物效果的防腐剂。例如,该溶液可包括约0.1至约0.5重量%的抗微生物防腐剂(基于该溶液的总重量),优选为0.40重量%(基于该溶液的总重量)。
申请人已经发现,当与包括其他类型的表面活性剂的传统湿擦拭物比较时,根据本发明不同方面的包含甜菜碱表面活性剂的湿擦拭物具有改善的触觉性质和清洁效力,而无过度的皮肤刺激。该溶液可进一步包括可作为乳化剂或提供额外的清洁性质的另外的表面活性剂。合适的辅助表面活性剂包括,例如阴离子表面活性剂,比如酰基谷氨酸盐和酰基羟乙基磺酸盐、烷醇酰胺(alkaolamids)、兼性表面活性剂、非离子性表面活性剂等或其组合。例如,合适的酰基谷氨酸盐阴离子表面活性剂为椰油酰谷氨酸钾(cocylglytamate),合适的酰基羟乙基磺酸盐阴离子表面活性剂为椰油酰羟乙基磺酸铵,而合适的兼性表面活性剂包括辛酰两性基二丙酸二钠(capryloamphdipropionate)和椰油酰两性基二乙酸二钠(disodiumcocoamphodiactetae)。合适的非离子性表面活性剂包括具有平均12至16个碳原子的二乙醇酰胺、烷基酚乙氧基化物、醇乙氧基化物、山梨坦酯、甘油酯等。该溶液可包括任何量的能提供改善的清洁或触觉特性的辅助表面活性剂。例如,该溶液可包括约0.01至约5重量%的辅助表面活性剂(基于该溶液的总重量)。在本发明的最优选实施方式中,本发明不包含辅助表面活性剂以限制可能的刺激。
此外,希望地本发明的湿擦拭物显现出低程度的起泡,以改善性能。该湿擦拭物也对使用者显现出光滑、柔滑的感觉,以改善消费者的接受度。
本发明包含至少一种合适的软化剂或合适的软化剂的组合,比如植物油脂(botanicalbutter)、维生素E乙酸酯及芦荟。本发明包含至少一种软化剂,其单个含量在约0.01%至约2%的范围内,更优选地,单个含量在约0.01%至约1.8%的范围内,最优选地,软化剂的单个含量为约1.5%,其中该重量百分比基于本发明的溶液的总重量。优选地,该软化剂为维生素衍生物,最优选地,该软化剂为维生素E乙酸酯。
申请人已发现,使用乙氧基化牛油树脂软化剂(优选为PEG-75乙氧基化牛油树脂甘油脂),可提供润肤性、乳化及共增溶至少一种另外的软化剂(优选为维生素E乙酸酯,其在本领域中众所周知不溶于水)的多种功能。优选地,本发明的乳化剂是植物油脂,更优选为乙氧基化的植物油脂,且最优选为乙氧基化的牛油树脂。在本发明优选实施方式中,该溶液包含购自Aarhuskarlshamn,商品名为Lipex102的最优选乳化剂,PEG-75乙氧基化牛油树脂。本发明包含至少一种乳化剂,其单个含量在约0.01%至约2%的范围内,更优选为单个含量在约0.01%至约1.8%的范围内,最优选为软化剂的单个含量为约1.5%,其中该重量百分比基于该本发明的溶液的总重量。
在制造本发明的溶液的过程中,将该乙氧基化牛油树脂甘油酯在50℃下,在分开的侧相(side-phase)混合容器中熔化。将维生素E乙酸酯加入此侧相容器中,并通过混合来将其溶解在乙氧基化牛油树脂甘油酯中。然后,在周围环境的室温下(约25℃)通过剧烈混合主要批次来将该侧相加入主要批次中。将乙氧基化牛油树脂甘油酯/维生素E乙酸酯相作为倒数第二种成分添加物加入其中。若该乙氧基化牛油树脂甘油酯和维生素E乙酸酯是以分开、独立的添加物形式(而非制造该侧相)添加在主要批次中,该维生素E乙酸酯将不会溶解在主要批次中;当混合终止时,该维生素E乙酸酯将以油的形式上升到该溶液的顶部。一旦加入乙氧基化牛油树脂甘油酯/维生素E乙酸酯后,然后加入丙二醇防腐剂相(含有丙二醇、对羟基苯甲酸酯和香料)并在周围温度下混合约15分钟。
本发明的溶液中可使用于约0.1至约2重量%范围内的另外的乳化剂,优选为温和的乳化剂,比如聚山梨醇酯20和其他乙氧基化的植物油脂,其中该重量百分比基于所述溶液的总重量。
本发明包含甘油以改善平滑度、提供润滑及作为保湿剂。可添加精油和植物提取物来作为香料。本发明包含使用至少一种香料以协助传达令个人的嗅觉愉悦的清新感和气味。本发明中可以采用源自植物提取物(比如黄瓜和春黄菊)的香料及各种香料,比如购自BellFragrancesCorporation的Bell该至少一种香料的量可为各自在约0.05重量%至约0.3重量%的范围内,其中该重量百分比基于所述溶液的总重量。
本发明进一步包含至少一种螯合剂,该螯合剂是经过设计以保护该植物提取物的结构完整性和香味,防止在溶液制造过程中可能会接触到不必要和不想要的铁。螯合剂的存在量可在约0.01至约0.1重量%的范围内,其中该重量百分比基于该溶液的总重量。本发明的优选螯合剂为商购自DowChemicalCompany的乙二胺四乙酸二钠。
本发明的不同方面的湿擦拭物可使用数种本领域技术人员所熟知的不同方法制造。本文所描述的特殊方法和步骤顺序并非用来限制本发明,而是仅公开来作为一种制作湿擦拭物和湿擦拭物叠的方法。首先,将被转换成湿擦拭物的材料供应卷展开,以提供连续移动的材料卷。通过本领域技术人员所熟知的任何合适的方式(比如喷洒、浸渍等)使材料卷饱和或以其它方式浸满本发明的溶液。
将材料卷在机器中切成多个条带,各条带可被折叠成对单个湿擦拭物而言所希望的折叠类型。如本领域技术人员所周知使用切刀将材料卷切开。例如,可将材料卷切成预定数量的单个条带。然后,将该材料条带折叠成折叠构形,比如z形折叠构形。例如,各材料条带可限定顶部折边部分(flapportion)、中间部分及底部折边部分。该顶部和底部折边部分连接中央部分并分别折叠在其上方和下方,以提供z形折叠构形。
然后,可组合各折叠条带,一个条带在另一个条带的上方,与其他预定数量的来自同一材料卷的折叠条带一起形成连续的巾(towel)。然后,将巾切成湿擦拭物的夹并将湿擦拭物的夹布置成堆叠构形。一叠中的夹的数量取决在在最后的包装中希望的叠数及湿擦拭物的数量,比如48或60张单个的湿擦拭物。定期检查湿擦拭物叠的重量,以确保该填加溶液是正确的。若不是,则调整该填加溶液。将湿擦拭物叠正确构形之后,可将其外加包装,优选使用塑料包装纸,再放置于容器(比如塑料桶)内部,以提供湿擦拭物包装。该容器提供用于湿擦拭物的基本上密封的环境,以尽量减少任何溶液从其中逸出。
关于用于制造包装在铝箔袋中的单个擦拭物的过程,将预先切开(优选为5英寸×6英寸),干燥的擦拭物放置在小袋中,然后将本发明的溶液加入小袋中。该小袋中的溶液对干燥擦拭物的比例较高,因为该小袋中会有一些溶液汇集。
因此,本发明的不同方面可有利地提供当与传统的湿擦拭物相比较时,具有改善的触觉性质及清洁力,但同时保持低皮肤刺激性和起泡的湿擦拭物。这样的湿擦拭物可有利地用于应用于妇女的肛门直肠和会阴区,当与传统的湿擦拭物相比较时,其具有改善的清洁效力,但不会过度刺激皮肤或起泡,且传达清新感和气味。另外的用途可包含婴儿擦拭物、手部擦拭物、脸部擦拭物、美容擦拭物、家用擦拭物、工业擦拭物等。
实施例
下列实施例是用于提供对本发明的更详细的理解。该特定材料和参数为示例性,并不意在限制本发明的范围。
实施例1
根据下列配方制备用于本发明的湿擦拭物的特别合适的溶液:
所描述的配方为澄清溶液,其含有20%w/w金缕梅作为活性成分。最终产品为以本溶液饱和的白色,湿润擦拭物。
尾注
1.金缕梅USP含有14.5%v/v酒精。该配方的酒精含量为约2.8至约3.0%w/w,其完全由金缕梅组分提供。
2.采用纯水作为漂洗水且直接加入。在所有情况中,该漂洗水随后被加入主要混合容器中。
实施例2
