发明效果
本发明的光亮性颜料可具有与以往的光亮性颜料不同的特征。该特征为例如向肌肤赋予的顺滑性、以及例如银色(silver)的、或者从黄色至橙色的颜色的、或者红色或其他颜色的不过强的显色。
附图说明
图1为用扫描型电子显微镜(SEM)对光亮性颜料的一例的截面进行观察而得的结果。
图2为用SEM对光亮性颜料的一例的表面进行观察而得的结果。
具体实施方式
以下,对本发明的实施方式进行说明,但以下的说明并不意在将本发明限制于特定的实施方式。
本说明书中,“主成分”是指含有率最高的成分。MMD是平均摩擦系数(MIU;meanfriction coefficient)的平均偏差(mean deviation of mean friction coefficient,平均摩擦系数的平均偏差)的简称。MMD是与肌肤触感的顺滑性对应的指标。MMD越低,触感的顺滑性越会提高。MMD的测定方法的详情在实施例的栏中进行说明。
本实施方式的光亮性颜料具备薄片状基体以及薄片状基体上的包含氧化锆的被膜(含有氧化锆的膜)。光亮性颜料具备以下特征中的至少一者、优选两者。
1)光亮性颜料的MMD为1.5以下
2)光亮性颜料的比表面积为0.5cm2/g以上
氧化钛由于其高折射率而作为可实现鲜艳的显色的被膜形成材料为人所知。然而,至少在改善向肌肤赋予的触感方面,存在研究替代材料的余地。本发明人对各种材料进行了研究,结果发现,氧化锆适于达成低的MMD。光亮性颜料的优选的MMD为1.0以下、0.8以下、进而0.6以下、尤其是0.5以下。MMD的下限没有特别限制,例如为0.01以上。
薄片状基体的种类也会对MMD造成影响。例如,薄片状基体为云母、合成云母、薄片状氧化铝、绢云母、薄片状二氧化钛、或薄片状氧化铁时,一般难以达成低的MMD。然而,若根据本实施方式,则即使使用这些薄片状基体,也能够达成1.5以下、例如超过1.0且为1.5以下的MMD。另一方面,薄片状基体为薄片状玻璃或薄片状二氧化硅时,若根据本实施方式,则能够达成1.0以下、进而低于1.0的上文中记载的范围(例如0.6以下)的MMD。
本实施方式的光亮性颜料可具有例如2.1以下、优选2.0以下、更优选1.5以下、根据情况的1.0以下的MIU。MIU的下限没有特别限制,例如为0.01以上。
被膜在薄片状基体上的形成一般通过液相成膜法来实施。为了得到MMD足够低的含有氧化锆的膜,期望预先对要析出氧化锆的表面实施前处理。前处理的一例是利用包含含有锡的盐的液体对该表面的接触处理。
发现利用包含含有锡的盐的液体的前处理使光亮性颜料的比表面积增加。比表面积的增加可成为有助于提高触感或其他受到比表面积的影响的特性的要因。比表面积的优选范围为0.8cm2/g以上、1.0cm2/g以上、2.0cm2/g以上、2.5cm2/g以上、3.0cm2/g以上、3.5cm2/g以上、4.0cm2/g以上。比表面积可以为4.5cm2/g以上。比表面积的上限没有特别限制,例如为100.0cm2/g以下、50.0cm2/g以下、20.0cm2/g以下、进而18.0cm2/g以下、根据情况的15.0cm2/g以下。
也发现虽然由含有氧化锆的膜赋予的光亮感稍低,但对于粉底等彩妆化妆品而言,反而可成为赋予高透明感的要因。基于L*a*b*表色***,本实施方式的光亮性颜料的使用D65光源所测定的反射色可具有30以上且小于70、进而35以上且68以下、尤其是40以上且65以下的L*。含有氧化钛的膜的上述L*通常高于70。另外,若适当地调整膜厚,则含有氧化锆的膜能够实现彩妆化妆品所期望的显色、具体而言从银色至黄色、橙色、红色、进而紫色的显色。需要说明的是,反射色的测定方法在实施例的栏中进行说明。
含有氧化锆的膜在赋予强的光亮感、显色的方面上比含有氧化钛的膜差。然而,含有氧化锆的膜在防止有时在含有氧化钛的膜中显著观察到的补色(日语:補色)的方面上比含有氧化钛的膜优异。若补色显著地显现,则有时观察到基于光亮性颜料的显色稍微不鲜艳。对于补色而言,光亮性颜料的添加量多时,容易发生问题。
以下,对构成光亮性颜料的薄片状基体和被膜进行说明。
(薄片状基体)
薄片状基体是也被称为鳞片状基体等的微小的板状薄片。薄片状基体例如为选自薄片状玻璃、薄片状氧化铝、薄片状石墨、薄片状氧化铁、薄片状二氧化钛、薄片状二氧化硅、氯氧化铋、云母、滑石和绢云母中的至少1种。薄片状基体优选为薄片状玻璃、薄片状氧化铝或云母。云母可以为天然云母,也可以为合成云母。以下,对作为特别优选的薄片状基体的薄片状玻璃进行说明。
构成薄片状玻璃的玻璃组合物是不仅包含氧化硅、还进一步包含氧化硅以外的金属氧化物的组合物,具体而言,可以是不仅包含氧化硅、还包含选自氧化铝、氧化钙和氧化钠中的至少一者的组合物。在玻璃组合物中,氧化硅可以是主成分。玻璃组合物中的氧化硅的含有率没有特别限制,例如为40质量%以上、45质量%以上,可以为75质量%以下。关于玻璃组合物,在换算为100μm的厚度时,在400~800nm的波长范围内可以具有超过60%、进而超过70%的透射率。具体而言,玻璃组合物可以是相当于选自钠钙玻璃、A玻璃、C玻璃、E玻璃、硼硅酸玻璃和铝硅酸玻璃中的至少一种的组合物。由这些多成分玻璃组合物构成的薄片状玻璃适于利用量产性优异的熔融法来制造。
薄片状玻璃的优选的平均粒径为1~180μm、3~120μm、根据情况的5~100μm。需要说明的是,薄片状玻璃的平均粒径设为通过在利用激光衍射法测定的光散射当量直径的粒度分布中从粒径小的一侧起的体积累积相当于50%时的粒径(D50)来确定。薄片状玻璃的优选厚度为0.1~10μm、进而0.2~5μm、尤其是0.25~2μm。若平均粒径和厚度过大,则不易得到具有充分良好的触感的光亮性颜料。其中关于厚度,有时可由厚度1~3μm的薄片状玻璃得到极其良好的触感。需要说明的是,这些数值范围也可以是薄片状玻璃以外的薄片状基体的优选的平均粒径和厚度。
薄片状玻璃可以利用例如吹制法来制造。吹制法是指以下方法:将原料碎玻璃熔融,将已熔融的玻璃从圆形狭缝连续地取出,此时从设置于圆形狭缝内侧的吹胀喷嘴吹入空气等气体而使熔融的玻璃膨胀成空心球状,并将发生膨胀而变薄的玻璃粉碎而制成薄片状(鳞片状)。作为薄片状玻璃,例如可使用由日本板硝子公司以GLASFLAKE(注册商标)系列销售的市售品。
与云母等结晶性粒体相比,薄片状玻璃的表面的平滑性优异。因此,薄片状玻璃特别适于实现足够低的MMD。
在优选的一个方式中,光亮性颜料具备薄片状玻璃以及在其表面直接形成的单层的含有氧化锆的膜。但是,也可以在薄片状基体的表面形成基底膜。在该情况下,包含氧化锆的被膜形成在基底膜的表面上。基底膜可以为单层,也可以为多层。基底膜可以为包含氧化物的膜。
(含有氧化锆的膜)
含有氧化锆的膜至少包含氧化锆。含有氧化锆的膜可以以氧化锆为主成分。含有氧化锆的膜的优选的膜厚为40~160nm、进而50~140nm、尤其是70~120nm、根据情况的90~110nm。基于含有氧化锆的膜的显色可通过控制膜厚而适当调整,随着膜厚变大,通常从银色向黄、橙、红、紫移动。在优选的一个方式中,含有氧化锆的膜的表面露出。
若考虑在彩妆化妆品中的使用,则含有氧化锆的膜的膜厚优选容易得到从银色经由黄、橙至红的显色的50~140nm。若考虑在粉底中的使用,则含有氧化锆的膜的膜厚优选容易得到从银色经由黄至橙的显色的50~120nm。但是,对于粉底以外的彩妆化妆品而言,由超过120nm且为160nm以下的范围的膜厚容易得到的从红至紫的显色有时也是有用的。
液相成膜法适合于含有氧化锆的膜在薄片状基体上的形成。该液相成膜法通常通过将薄片状基体分散于包含含有锆的盐的液体、并对该液体进行搅拌来实施。液体可以是溶解有含有锆的盐的水溶液。含有锆的盐例如为硫酸锆、氯氧化锆(日文:酸塩化ジルコニウム)、碳酸锆铵。根据需要,可以在液体中投入酸等pH调节剂。pH例如可调节至1.9~4.0、进而2.0~3.5的范围。
如上所述,通过使用了包含含有锡的盐的液体的前处理,从而容易从含有氧化锆的膜得到足够低的MMD。基于该前处理的MMD降低的机制在现阶段虽不明确,但存在以下可能性:生成的氧化锆的表面、密度受到影响,其结果,MMD降低。包含含有锡的盐的液体可以为溶解有含有锡的盐的水溶液。含有锡的盐例如为氯化锡,更具体而言,为氯化锡(II)、氯化锡(IV)、氯化锡(II)二水合物、氯化锡(IV)五水合物。
以下,对包含光亮性颜料的组合物和涂装体进行说明。
(组合物和涂装体)
本实施方式的含有颜料的组合物包含本实施方式的光亮性颜料。作为组合物,可以例示选自涂料、油墨、化妆料和树脂组合物中的至少一者。作为树脂组合物,可以例示人造大理石成型品。本实施方式的涂装体具备基材和其上的涂膜,涂膜包含本实施方式的光亮性颜料。作为涂装体,可以例示涂装纸。但是,基材并不限于纸,也可以是金属、树脂、陶瓷或其他基材。涂膜可以包含本发明的含有颜料的组合物。
本实施方式的光亮性颜料的特征在将颜料作为化妆料使用时容易被识别为优点。化妆料没有特别限定,可以为乳霜(日文:クリーム)等基础化妆品、头发定型剂等护发化妆品、身体乳霜、爽身粉、止汗剂、防晒剂等身体护理产品、入浴剂等,优选为粉底、睫毛膏、眼影、眼线、口红、唇彩、腮红、指甲油等彩妆化妆品。彩妆化妆品可以为口红、腮红等局部彩妆化妆品,也可以为遮瑕膏、粉底、定妆粉等基础彩妆化妆品。
化妆料的方式没有特别限定,例如为粉末、棒、笔、乳霜、乳液、分散体、油、片剂、胶囊、线笔(日文:ライナー)、涂剂、凝胶或其他方式。例如,粉底可以为饼型、粉末型、乳霜型、液体型中的任一种。化妆料中,作为光亮性颜料以外的成分,可包含以往使用的成分。光亮性颜料以外的成分根据化妆料的种类而适当选择。化妆料也可以包含光亮性颜料以外的颜料。
例如在粉底中配合体质颜料、着色颜料、白色颜料、珍珠光泽颜料等。体质颜料是为了赋予进展性(日文:進展性)、附着性、进而赋予光泽而使用的,也作为增量剂而使用。着色颜料是为了赋予基本的色调而使用的。白色颜料是为了赋予隐蔽力、白色而使用的。珍珠光泽颜料是为了赋予珍珠光泽(珠光效果)而使用的。局部赋予光泽即可的珍珠光泽颜料在粉底中的配合量最多为粉底总量的8质量%左右。与此相对,体质颜料可以说是形成粉底的骨架的基本成分,并且为了调整粉底整体的特性,通常配合比上述更多的量。
化妆料可以包含少量的、换言之光亮性颜料作为珍珠光泽颜料发挥功能的程度的本实施方式的光亮性颜料,也可以包含相当量的、换言之光亮性颜料实质上作为体质颜料或与其类似的颜料发挥功能的程度的本实施方式的光亮性颜料。在后者的情况下,可以将相对于化妆料总量的光亮性颜料的含量设为例如10质量%以上、尤其是12~30质量%。
以下,通过实施例来说明本发明的具体例,但以下的实施例也并不出于限制本发明的意图提出。光亮性颜料的特性如下地进行评价。
(触感:MIU和MMD)
与滑动性对应的MIU以及与顺滑性对应的MMD使用KATO TECH公司制的摩擦感测试仪“KES-SE”进行测定。摩擦件使用10mm见方的硅酮元件,测定条件设为静负荷50g、测定速度1mm/秒。将光亮性颜料以每单位面积的质量为1.3mg/cm2的方式均匀散布于黑色人工皮革(IDEATEX JAPAN公司制“PROTEIN LEATHER(注册商标)合成皮革”)上,而制作测定对象试样。需要说明的是,测定时的相对湿度为54%。
(反射光:亮度和颜色)
反射光的亮度L*使用柯尼卡美能达公司制的测色计“CR-400”进行测定。将光亮性颜料以成为10质量%的方式添加至透明丙烯酸类树脂(日本油漆公司制NIPPE ACRYL“AutoClear Super”)中并混合,将所得的组合物涂布在白底/黑底的隐蔽率测定用纸上,而制作测定对象试样。组合物以涂膜的厚度成为9mil(约228.6μm)的方式进行涂布,但干燥后的涂膜的厚度成为70~80μm。所用的光源为D65光源,测定面为黑底涂布面。测定的反射光设为垂直反射光。测定的反射光使用CIE2°视野等色函数进行观测。
(膜厚、基体厚度)
被膜的膜厚和基体的厚度通过使用扫描型电子显微镜(SEM)观察光亮性颜料的截面来测定。
(平均粒径D50)
对于薄片状基体的平均粒径而言,将作为测定对象的薄片状基体分散于水中,用Microtrac公司制“MT3300”测定体积累积50%当量直径(D50)。
(比表面积)
使用Quantachrome Instruments公司制“NOVA4200e”,利用氮气法,测定BET比表面积。
(试样1)
·薄片状基体的前处理
作为薄片状基体,使用平均粒径(D50)为80μm、厚度为1.3μm的薄片状玻璃。本示例和以后的示例中使用的薄片状玻璃均为日本板硝子公司制GLASFLAKE(注册商标),并由多成分玻璃构成。该多成分玻璃包含SiO2、Al2O3、MgO和CaO,还包含碱成分(选自Li2O、Na2O和K2O中的至少一种)。首先,将薄片状基体150g与水1.5L进行混合并搅拌。接着,向其中添加盐酸,将pH调节至1.45~1.55。接下来,向其中添加浓度1.3质量%的氯化锡(IV)水溶液9.06mL。然后,进一步继续搅拌,通过过滤将粉末与液体分离。将所分离的粉末分散于水中,再次进行过滤,得到了已完成前处理的薄片状基体。
·含有氧化锆的膜的形成
将已完成前处理的薄片状基体150g与水1.5L混合,升温至75±3℃。接着,向其中添加盐酸和氢氧化钠,调节至pH2.0~3.5。接下来,一边维持上述pH,并且同时一边滴加浓度20质量%的硫酸锆水溶液和浓度10质量%的氢氧化钠水溶液4小时,被覆氧化锆膜。然后,通过过滤将粉末与液体分离。对于所分离的粉末,依次实施:分散在已用盐酸调节至pH2.0~3.5的水溶液中并搅拌、然后进行过滤的操作2次;以及分散在水中并搅拌、然后进行过滤的操作2次。最后,将粉末在180℃的气氛下干燥12小时,在600℃进行2小时烧成。如此地,得到了在表面形成有含有氧化锆的膜的薄片状基体。

作为薄片状基体,使用平均粒径(D50)为160μm、厚度为1.3μm的薄片状玻璃,除此之外,与试样4同样地操作,得到了在表面形成有含有氧化锆的膜的薄片状基体。
(试样9)
在含有氧化锆的膜的形成工序中,将滴加时间设为4小时30分钟,除此之外,与试样1同样地操作,得到了在表面形成有含有氧化锆的膜的薄片状基体。
(试样10)
在含有氧化锆的膜的形成工序中,将滴加时间设为4小时45分钟,除此之外,与试样1同样地操作,得到了在表面形成有含有氧化锆的膜的薄片状基体。
(试样11)
在含有氧化锆的膜的形成工序中,将滴加时间设为6小时,除此之外,与试样1同样地操作,得到了在表面形成有含有氧化锆的膜的薄片状基体。
(试样12)
不实施薄片状基体的前处理,通过以下而形成含有氧化锆的膜。所用的薄片状基体与试样1相同。
·含有氧化锆的膜的形成
向水150mL中添加盐酸,将pH调节至2.0~3.5。向其中依次添加尿素0.5g和硫酸锆21g。接下来,向其中添加薄片状基体6g,进而进行搅拌。然后,通过过滤将粉末与液体分离。然后,将所得到的粉末用水洗涤,在90℃干燥1.5小时,进而在800℃进行1小时烧成。如此地,得到了在表面形成有含有氧化锆的膜的薄片状基体。
(试样13)
使用了日本板硝子公司制“METASHINE(注册商标)MT1080RS”。
(试样14)
作为薄片状基体,使用平均粒径(D50)为10μm的日本光研工业株式会社制合成云母,除此之外,与试样1同样地操作,得到了在表面形成有含有氧化锆的膜的薄片状基体。需要说明的是,合成云母的厚度为数μm以下。
(试样15)
使用在作为薄片状基体的合成云母的表面形成有含有氧化钛的膜的Merck公司制“Timiron Ice Crystal”。
将评价的结果示于表1和表2。需要说明的是,表1和表2的“-”是指未测定,表2的“*”是指“从亚微米至数μm的宽范围”。
[表1]
·对于试样12,未实施锡前处理。
[表2]
·云母的厚度分布在从亚微米至数μm的宽范围。
根据表1和表2能够理解,相比于含有氧化钛的膜,含有氧化锆的膜在光亮性颜料给予的顺滑性的方面上更优异。顺滑性的改善在使用薄片状玻璃作为薄片状基体的情况下变得显著。另外能够理解,相比于含有氧化钛的膜,含有氧化锆的膜更适于实现受到抑制的亮度。也能够理解,薄片状基体的锡前处理有助于MMD的降低和比表面积的增加。
需要说明的是,试样1~13的MIU在0.8~3.8的范围内。MIU为1.5以下的是试样1、4、9-11,其薄片状基体的D50为100μm以下,厚度在1~3μm的范围内,并且具有含有氧化锆的膜。
使用试样4~11、13和15的光亮性颜料,基于表3的配方制备粉底。将粉底涂布于肌肤,基于以下的指标对其外观进行评价。
4分:可见肌肤自然明亮。也不炫目。
3分:可见肌肤明亮,但稍有炫目。
2分:肌肤为稍微不自然的色调。
1分:肌肤可见不自然的炫目。
[表3]
(粉底配方)
在表4中与光亮性颜料的触感(MIU和MMD)一起地示出结果。
[表4]
需要说明的是,按照与上述同样的配方将具有含有氧化钛的膜的光亮性颜料(试样13和15)配合在粉底中并对外观进行了评价,结果全部为“1分”。作为为了调整粉底整体的特性而添加的颜料,具有含有氧化锆的膜的光亮性颜料比具有含有氧化钛的膜的光亮性颜料更优异。
使用SEM对形成有含有氧化锆的膜的薄片状基体进行观察,将结果示于图1和图2。在图1所示的截面中,示出了膜厚90nm的含有氧化锆的膜。如图1和图2所示,含有氧化锆的膜由数十nm左右的大小的粒子致密地构成。
