Abstract

头发处理组合物，其包含组合物的40至95重量％的硅氧烷弹性体，0.01至5％的二氧化硅和0至2重量％的水。

Description

组合物
本发明涉及包含硅氧烷弹性体的头发组合物。
尽管已有现有技术，但仍然需要改进的定型组合物。特别是仍然需要在应用期间具有改善的消费者体验的定型组合物。
因此，提供了一种头发处理组合物，其包含占组合物的40至95重量％的硅氧烷弹性体，0.01至5％的二氧化硅和0至2重量％的水。
本发明的组合物为消费者在使用期间提供了优越的体验。特别地，该产品在手中表现为凝胶，但是当在手之间摩擦时软化从而提供容易涂抹在头发上的光亮的干质感层。这可以应用于干燥或湿的头发，以得到保持光亮且卷曲减少的顺滑、柔软处理。
本发明的产品提供改善的消费者体验，因为它更容易进入头发起作用。该组合物在起作用时还具有干燥感，而现有技术的水基产品往往感到潮湿和粘腻。另外，现有技术的硅氧烷基产品倾向于具有低水平的低粘度硅氧烷(即非弹性体)，并且由于它们往往从手指滴落而难以用手使用。这使得它们难以用手使用，且也使它们难以在使用后从手中洗掉。这也使它们笨重且油腻。
硅氧烷弹性体是本领域所公知的。参见(http：//www.dowcorning.com/content/ publishedlit/Chapterl6.pdf)“硅氧烷弹性体分散体是可通过氢化硅烷化反应制备的交联凝胶。该反应涉及低水平的催化剂，通常是铂的衍生物，并且通常加入足够的溶剂。含有SiH的硅氧烷聚合物与二乙烯基材料反应以连结独立的硅氧烷链。如果反应在作为溶剂的环状PDMS中进行，则其导致溶胀的和松散网状的网络或硅氧烷弹性体分散体的形成”。本发明中使用的硅氧烷弹性体及它们的制备方法描述在US4987169，US8222363和US5654362中。
本发明中使用的硅氧烷弹性体是松散网状的硅氧烷在溶剂中的分散体。
溶剂的例子包括异癸烷、新戊酸异癸酯、环戊硅氧烷、聚二甲基硅氧烷(dimethicone)、异己烷、乙烯基聚二甲基硅氧烷和氢化聚二甲基硅氧烷。
可分散在溶剂中形成弹性体的硅氧烷的例子包括：
-聚二甲基硅氧烷/双-异丁基PPG-20交联聚合物，聚二甲基硅氧烷交联聚合物，聚二甲基硅氧烷，乙烯基聚二甲基硅氧烷，氢化聚二甲基硅氧烷，2，4，6，8-四乙烯基环四硅氧烷；
-异十二烷(和)聚二甲基硅氧烷/双-异丁基PPG-20交联聚合物，可作为硅氧烷弹性体EL-8051商购自Dow Corning；
-新戊酸异癸酯(和)聚二甲基硅氧烷/双-异丁基PPG-20交联聚合物，可作为硅氧烷弹性体EL-8052商购自Dow Corning；
-异十六烷(和)聚二甲基硅氧烷/双-异丁基PPG-20交联聚合物，可作为硅氧烷弹性体9040商购自Dow Corning；
-环戊硅氧烷(和)聚二甲基硅氧烷交联聚合物，可作为硅氧烷弹性体9041商购自Dow Corning；
-聚二甲基硅氧烷(和)聚二甲基硅氧烷交联聚合物，可作为硅氧烷弹性体9045商购自Dow Corning；和
-聚二甲基硅氧烷、乙烯基聚二甲基硅氧烷、氢化聚二甲基硅氧烷、2，4，6，8-四乙烯基环四硅氧烷。
硅氧烷弹性体(分散在溶剂中的硅氧烷)以组合物的40至95重量％，优选42至85％存在于本发明组合物中。
本发明的组合物还包括二氧化硅。优选地，二氧化硅是气相二氧化硅(fumedsilica)。
更优选地，二氧化硅当加入本发明的组合物时被悬浮在油中。油有助于二氧化硅在组合物中的悬浮。当二氧化硅是气相二氧化硅时，优选油是轻矿物油或香精油。如果使用重质矿物油，气相二氧化硅中的空气会捕集在油中，结果是过稠的组合物，其不适合于用作使用手施加入头发的化妆品制剂。
优选地，轻质矿物油的密度为0.7至0.85g/ml。矿物油的密度也称为比重，并根据ASTM D4052在15.6℃测定。
优选地，二氧化硅以组合物的0.01至5重量％，更优选为0.05至2重量％存在。
优选地，本发明的组合物还包含挥发性硅氧烷。合适的挥发性硅氧烷是在本领域熟知的，包括可商购自Dow Corning的DC245。
优选地，并且当存在时，挥发性硅氧烷以组合物的1至30重量％，优选1至5重量％存在。
优选地，组合物包含0至2重量％的水，更优选0至1重量％的水，以及最优选0至0.01重量％的水。
优选地，本发明的组合物包括定型助剂。优选的定型助剂包括硅氧烷树脂。特别优选的硅氧烷树脂已知为MQ树脂。
MQ树脂是单官能的硅烷(M)和四官能的硅烷(Q)之间的缩合产物。优选MNQ树脂可商购自Dow Corning，并包括MQ树脂CF-0410。
MQ树脂以组合物的0.1至5重量％，优选2至4重量％存在。
优选地，组合物还包括选自矿物油，植物油和动物油的油。优选地，这种油以组合物的1-30重量％，且更优选3-10重量％存在。
