Abstract
提出一种用于抵抗恶臭的组合物，其包含以下物质或由以下物质组成：(a)至少一种生理清凉剂和(b)至少一种吸水聚合物和/或水凝胶。
Description
发明领域
本发明涉及恶臭减少领域，并涉及一种用于抵抗特定女性体臭的新组合物、一种抵抗此类恶臭的方法和一种确定此类恶臭的方法。
发明背景
体臭是主要用来描述人们通过皮肤呼出的所有有气味的身体气味的术语。最明显可察觉的气味是汗液的气味，其中只有主要位于腋窝的顶浆汗腺的分泌物才有气味。然而，气味剂仅在细菌分解腋下汗液中所含物质，包括人体自身的脂肪和蛋白质时产生。对于许多人来说，难闻的体味是一个严重的问题。目前全球除臭剂市场价值约为200亿欧元，预计到2025年将增长10％。
然而，抵抗与尿液并且特别是经血排泄相关的气味仍然是一个特殊的挑战。相应的卫生产品，例如尿布、护垫和卫生巾，含有所谓的超级吸收剂来吸收体液。这些超级吸收剂具有吸收液体的特性，从而使物质的体积膨胀许多倍。由于液体储存在聚合物基质内，因此超级吸收剂的外部保持干燥。
然而，即使当液体被吸收时，难闻的气味仍然存在。因此，卫生用品通常会精心加香，但其唯一的目的是掩盖难闻的气味。有时这或多或少是成功的，但特别地，气味成分一次又一次地混合，甚至令人不快地加剧。
相关现有技术
US 6,379,652 B1(COLGATE)公开了一种抑制口腔恶臭并提供持久口气保护的方法，其中将口腔组合物施用于使用者的口腔，所述口腔组合物包含口腔可接受的载体，其中含有风味系统，所述风味系统由精油和清凉剂化合物的混合物组成，所述清凉剂化合物是用C1-C4烷基酯化的具有2至6个碳原子的天然羧酸的薄荷酯。

发明目的
因此，本发明的任务是提供用于卫生用品的新的替代组合物，该组合物不会通过更强烈的固有气味克服难闻的气味；特别是与女性体味、尿液、氨和蛋白质降解产物相关的气味，，而是在低浓度下就已经中和它们。
发明内容
本发明的第一个目的涉及一种用于抵抗恶臭的组合物，其包含以下物质或由以下物质组成：
(a)至少一种生理清凉剂和
(b)至少一种吸水聚合物和/或水凝胶。
尽管消除恶臭是一个经过充分研究的问题；然而，代表典型香料成分的乙酸薄荷酯与婴儿湿巾、女性卫生湿巾或类似应用中常用的吸水性聚合物之间的相互作用是一种用于释放适当的高恶臭抵消作用的新的且令人惊讶的方式。
生理清凉剂
形成组分(a)的生理清凉剂优选选自下表中所示的种类(包括它们的旋光异构体和外消旋体)：
形成组分(b)的物质的第一个重要代表是琥珀酸单薄荷酯，其早在1963年由Brown&Williamson Tobacco公司获得物质专利权(US 3,111,127)，以及作为冷却剂，是专利号US 5,725,865和5,843,466(V.Mane Fils)的主题。所述琥珀酸酯和类似物谷氨酸单薄荷酯两者都是基于二羧酸和聚羧酸的单薄荷酯的重要代表：
这些物质的应用实例可见于文献WO 2003 043431(Unilever)或EP1332772 A1(IFF)。
在本发明的定义中优选的薄荷醇类化合物的下一重要组包括薄荷醇和多元醇，如乙二醇、甘油的碳酸酯或碳水类化合物，例如薄荷醇乙二醇碳酸酯、薄荷醇丙二醇碳酸酯、薄荷醇2-甲基-1，2-丙二醇碳酸酯或相应的糖衍生物：
所述物质作为香烟用清凉剂的用途是例如1968年的专利US3,419,543(Mold等)的主题；在DE4226043A1(H&R)中要求保护其作为生理清凉剂的用途。
在本发明中，优选的薄荷醇类化合物是乳酸薄荷酯，尤其是薄荷酮甘油缩醛或薄荷酮甘油缩酮。
前一个结构通过乳酸和薄荷醇的酯化反应得到，后一个结构通过薄荷酮与甘油的缩醛化反应得到(参见DE 2608226A1，H&R)。该组化合物也包括3-(1-薄荷氧基)-1，2-丙二醇，又称为Cooling Agent 10(清凉剂10)以及3-(1-薄荷氧基)-2-甲基-1，2-丙二醇，其具有额外的甲基。
例如，3-(1-薄荷氧基)-1，2-丙二醇通过根据下图的方案以薄荷醇为起始进行(参见US 4,459,425，Takagaso)：
替代的路线，其中薄荷醇在第一步与表氯醇反应，如US6,407,293和US 6,515,188(Takagaso)所记载。在下文中给出了以C-O键为特征的优选的薄荷醇类化合物的概述：
在所有这些物质中，优选薄荷酮甘油缩醛/酮和乳酸薄荷酯以及乙二醇碳酸薄荷酯和丙二醇碳酸薄荷酯。
在1970年代第一次发现薄荷醇化合物，其在3位有一个C-C-键并且同样有一系列可以在本发明中使用的代表物。这类物质通常被称为WS-类。本体是薄荷醇衍生物，其中羟基被羧基取代(WS-1)。所有其他的WS-类由该结构产生，如例如WS-3、WS-4、WS-5、WS-12、WS-14和WS-30，均在本发明中优选。下面两张图显示了合成路线：
衍生自WS-1的酯记载于例如US 4,157,384中，并且相应的N-取代的酰胺记载于J.Soc.Cosmet.Chem.pp.185-200(1978)。
优选的制剂选自组包括：
·薄荷醇甘油缩醛
·薄荷醇甘油缩酮
·薄荷醇薄荷醚
·薄荷酮甘油缩醛
·薄荷酮甘油缩酮
·薄荷氧基-1，2-丙二醇

特别优选的是乙酸薄荷酯。
超级吸收剂
超吸收性聚合物(SAP)也称为泥粉(组分b)，可以吸收并保留相对于其自身质量而言极其大量的液体。吸水聚合物在混合时被归类为水凝胶，通过与水分子形成氢键来吸收水溶液。SAP的吸水能力取决于水溶液的离子浓度。在去离子水和蒸馏水中，SAP可以吸收其重量300倍(其自身体积的30至60倍)，并且可以变成高达99.9％的液体，但当放入0.9％的盐溶液中时，吸收能力会下降到它重量的大约50倍。溶液中价态阳离子的存在会阻碍聚合物与水分子结合的能力。
总吸收性和溶胀能力由用于制备凝胶的交联剂的类型和程度控制。低密度交联SAP通常具有较高的吸收能力和较大的溶胀程度。这些类型的SSAP还具有更软和更粘的凝胶结构。高交联密度聚合物表现出较低的吸收能力和溶胀，但凝胶强度更坚固，即使在适度的压力下也能保持颗粒形状。
在本发明的上下文中，优选的SAP选自聚丙烯酸酯、聚丙烯酰胺、聚乙烯吡咯烷酮、支链淀粉、明胶、纤维素及其混合物。超吸收性聚合物通常由丙烯酸与氢氧化钠共混物在引发剂存在下聚合形成聚丙烯酸钠盐(有时称为聚丙烯酸钠)而制成。其他材料也用于制造超吸收性聚合物，例如聚丙烯酰胺共聚物、乙烯马来酸酐共聚物、交联羧甲基纤维素、聚乙烯醇共聚物、交联聚环氧乙烷以及聚丙烯腈的淀粉接枝共聚物等。后者是创建的最古老的SAP表单之一。
如今，超吸收性聚合物是使用三种主要方法之一制备的：凝胶聚合、悬浮聚合或溶 液聚合。每种工艺都有各自的优点，但都能产生一致的产品质量。
凝胶聚合。将丙烯酸、水、交联剂和紫外线引发剂化学品的混合物混合并放置在移动带上或大桶中。液体混合物随后进入″反应器″，其为一个带有一系列强紫外线的长型室。紫外线辐射驱动聚合和交联反应。所得″原木″是含有60-70％水的粘性凝胶。原木被切碎或磨碎，然后放入各种干燥器中。可以将额外的交联剂喷涂在颗粒的表面上；这种″表面交联″提高了产品在压力下的溶胀能力，该特性以负载下吸收率(AUL)或抗压吸收率(AAP)来衡量。然后筛选干燥的聚合物颗粒以获得适当的粒度分布和包装。凝胶聚合(GP)方法是目前最流行的用于制造婴儿尿布和其他一次性卫生用品中使用的聚丙烯酸钠超吸水性聚合物的方法。
溶液聚合。溶液聚合物提供以溶液形式提供的粒状聚合物的吸收性。溶液可以在使用前用水稀释，并且可以涂覆大多数基材或用于将其浸透。在特定温度下干燥特定时间后，得到具有超吸收性的涂层基材。例如，这种化学物质可以直接应用于电线和电缆，尽管它特别适合用于卷状货物或片状基材等部件。如今，基于溶液的聚合通常用于共聚物的SAP制造，特别是那些使用有毒丙烯酰胺单体的聚合。该过程非常高效，并且通常具有较低的资本成本基础。溶液法使用水基单体溶液产生大量反应物聚合凝胶。聚合反应自身的放热反应能量用于驱动大部分过程，有助于降低制造成本。然后将反应聚合物凝胶切碎、干燥并研磨至其最终颗粒尺寸。任何增强SAP性能特征的处理通常是在最终颗粒尺寸形成后完成的。
悬浮聚合。只有少数公司采用悬浮工艺，因为它在聚合步骤中需要更高程度的生产控制和产品工程。该过程将水基反应物悬浮在烃基溶剂中。最终结果是悬浮聚合在反应器中产生初级聚合物颗粒，而不是在反应后阶段机械地产生。性能增强也可以在反应阶段期间或之后进行。
组合物
根据本发明的组合物可以包含重量比为约10：90至约5：95且优选约0.1：99.9至约1：99的化合物(a)和(b)。
本发明还涵盖一种生产所述组合物的方法，其包括以下步骤或由以下步骤组成：
(a)提供至少一种薄荷醇衍生物的水溶液；
(b)提供至少一种吸水聚合物和/或水凝胶；和
(c)使所述至少一种吸水聚合物和/或水凝胶与所述的至少一种薄荷醇衍生物的水溶液接触。
工业应用
本发明的另一个目的涉及一种包含所述组合物的卫生产品。优选地，所述产品代表尿布，特别是婴儿尿布、护垫或卫生巾。
本发明还涉及组合物用于对抗、掩蔽和/或中和恶臭、特别是女性体味的用途。
实施例
实施例1至3-对比实施例C1至C7
恶臭中和评估
以下实验的目的是评估对抗嗅探盒中女性卫生恶臭的性能。为此，12名专家组成的小组对嗅探盒中的样品进行了评估。将恶臭物放在不同的棉球上，并与培养皿中的原料一起放入容量为7L的密闭气囊中。在连续线标度上评估香料和恶臭强度，十个标签范围从″无气味″(0)到″可想象的最强″(10)气味，″中等″(5)是未加香料的恶臭参考样本。请注意，小组成员在评分时只能看到口头锚点，而不是数字(0-10)。结果是各个小组成员评级的算术平均值。随后，通过弗里德曼测试(Friedmann-Test)对从嗅觉测试中获得的数据进行统计评估，以了解样品之间的总体差异，然后进行成对比较，以确定各个样品之间的显着差异。结果如表1所示：
表1
女性卫生品(每个样品加1克水)
MO＝用于女性卫生品的人工恶臭模型
SAP＝聚(甲基丙烯酸甲酯-共-甲基丙烯酸丁酯
结果清楚地表明，向所述超强吸收剂中添加一种生理凉味剂显着减少了恶臭。特别地，对于含有″MO+超强吸收剂(+1g水)+清凉剂″的样品，显示出比″MO+超强吸收剂(+1g水)″和″MO+清凉剂(+1g水)″显着更低的恶臭强度。
