Abstract

本說明書提供包含一防滲層之一化妝品組合物施用器。本說明書之化妝品組合物施用器係被設計使得一化妝品組合物被一施用層而非一彈性層吸收。藉此，能確保防潮之持久性且能維持該施用器之彈性和親膚性。此外，該化妝品組合物對皮膚之導送率可被提高，其係藉由抑制該化妝品組合物施用器吸收該液狀化妝品組合物。

Description

包含防滲層之化妝品組合物施用器
本說明書係關於一種化妝品組合物施用器。
[參考文件]  韓國專利公報2013-0122560。
由於可攜式液狀化妝品組合物及化妝品組合物施用器之使用增加，尋求方便使用之施用器。現存可攜式容器型施用器不利之處在於化妝效果(cosmetic effect)會隨時間降低，因為該施用器之彈性及親膚性(pleasantness)會降低。
在可便於容置化妝品組合物之粉餅型(pact-type)容器中提供經薄化處理之海綿，使易於上妝或修飾妝容(makeup)。使用時置於該容器中之化妝品組合物施用器會被油類、濕氣、皮脂及灰塵污染，且其通常會被長時間保留在該容器內部。尤其低黏性化妝品組合物及該施用器間之相容性會影響該化妝品組合物施用器之壽命(life span)。
通常一化妝品組合物施用器可由以下組成：一施用層(application layer)，其係由具有細孔(fine pores)之泡沫體(foam)形成，用以提供適合之化妝效果；一彈性層(elastic layer)，其係由泡沫體形成，以使妝容有良好之貼合性(application)及黏附性(adhesion)；及一覆蓋層(cover layer)，用以避免手之污染。該泡沫體可為有孔之泡沫體，且端視起泡程度、起泡方法等而可為各種型式。該泡沫體可被分為一適於施用者及一適於作為支撐(support)者。該泡沫體會吸收內容物(contents)。尤其很會吸收低黏性之液狀內容物。該含有彈性層之化妝品組合物施用器具有良好彈性且提供初始親膚感(pleasant feeling)。然而，該彈性會隨著該泡沫體逐漸吸收內容物而下降，結果造成親膚感也下降。主要使用以酯為主(ester-based)之聚氨酯(polyurethane)作為該彈性層之泡沫體。然而，該以酯為主之聚氨酯易受潮。雖然以醚為主(ether-based)之聚氨酯能防潮，其具有無法以熱加工法(thermal processing)封裝之問題。
[技術問題] 本說明書涉及提供一化妝品組合物施用器，其能藉由增加化妝品組合物對皮膚之導送率(delivery ratio)及維持柔軟觸感、彈性及親膚感而提升化妝效果，由於該化妝品組合物施用器對該化妝品組合物之吸收被抑制。
[技術手段] 在一態樣中，本說明書提供一含有防滲層之化妝品組合物施用器。
[有利之效果] 本說明書之化妝品組合物施用器係被設計成可使一化妝品組合物被施用層而非彈性層吸收。藉此可確保防潮持久性，並可維持該施用器之彈性及親膚性。而且，該化妝品組合物對皮膚之導送率可被提高，其係藉由抑制該化妝品組合物施用器對該液狀化妝品組合物之吸收。
[最佳實施方式] 在本說明書中，一「施用器」係指用以導送任何材料(material)或物質(substance)至皮膚之工具。該術語係以最廣泛之概念使用，其包含任何實施手段，諸如粉撲(puff)、棒(tips)、刷(brush)等。
在本說明書中，一「泡沫體」係指藉由起泡然後硬化聚氨酯、橡膠、塑膠等所形成之物質。
在本說明書中，「吸收率」係指任何材料或物質被施用器等吸收時之程度。理想吸收量既不會太多也不會太少。
在本說明書中「導送率」係指任何材料或物質由一施用器至一物體之有效導送之程度。
在下文中，本說明書特定之例示性具體實施例係被詳述以使得本說明書所屬技術領域之普通技術人士可以輕易實施本說明書。
在一態樣中, 本說明書提供一含有防滲層之化妝品組合物施用器。
具體地，本說明書例示性具體實施例之化妝品組合物施用器可含有一施用層、接觸該施用層下側之一防滲層及接觸該防滲層下側之一彈性層。而且，其可進一步包含接觸該彈性層下側之一覆蓋層。
在本說明書之例示性具體實施例中，該施用層係直接接觸一化妝品組合物 (下文中也稱作內容物)且將該化妝品組合物導送及施用至皮膚之層。該彈性層係使該化妝品組合物施用器產生觸感及提供彈性之層，如此使得該化妝品組合物被施用及黏附在皮膚上。該覆蓋層，也稱作防污層(contamination-preventing layer)，係在手持該化妝品組合物施用器時避免手及該施用器被污染之層。
在本說明書之例示性具體實施例中，抑制該化妝品組合物(內容物)之吸收之該防滲層係被引入該施用層及該彈性層之間，藉此提供可藉由抑制該彈性層及該覆蓋層吸收該內容物而維持該施用器之彈性及親膚感之施用器。
在本說明書之例示性具體實施例中，該化妝品組合物施用器中該施用層之一側可與該防滲層一體成形(formed integrally)。例如，該施用層之下側與該防滲層可相同。在一例示性具體實施例中，該防滲層及該施用層可不需額外加工而製得，其係藉由在該防滲層上製備及起泡該施用層。若該施用層係如上述與該防滲層一體成形，該化妝品組合物係經由該施用層之上側(upper side)被吸收，但無法穿透其下側。
在本說明書之例示性具體實施例中，該防滲層係位於該施用層及該彈性層之間，且可由熱密封加工法(thermal sealing processing)接合之材料形成。
在本說明書之例示性具體實施例中，該防滲層可具有0.01-3.0 mm之厚度。當該厚度係在上述範圍中，由於其高度可加工性，一強力之接合係被形成在該施用器之邊緣(edge)。同時，由於對皮膚有良好之黏附性，該施用器具有柔軟觸感且提供改進之化妝效果。
在一例示性具體實施例中，該防滲層可具有2-10 kg/cm3 之抗拉強度(tensile strength)及200%或以上之伸長率(elongation percentage)。
在本說明書之例示性具體實施例中，該防滲層可包含由一或多種材料製成之防滲膜，該材料係選自於由以下所組成之群組：聚氨酯(polyurethane)、矽氧烷(silicone)、聚乙烯(polyethylene)、 聚丙烯(polypropylene)、聚烯烴(polyolefin)、丙烯腈丁二烯橡膠 (acrylonitrile butadiene rubber ，NBR)、聚氯乙烯(polyvinyl chloride)、乙烯乙酸乙烯酯丁基橡膠(ethylene-vinyl acetate butyl rubber，EVA)、苯乙烯-異戊二烯-苯乙烯(styrene-isoprene-styrene ，SIS)、 苯乙烯-乙烯-丁烯-苯乙烯 (styrene-ethylene-butylene-styrene ，SEBS)、聚乙烯醇(polyvinyl alcohol ，PVA)、腈橡膠(nitrile rubber)、丁基橡膠(butyl rubber)、氯平橡膠 (chloroprene rubber ，Neoprene®)及聚酯(polyester)或該等材料之聚合物。
在本說明書之例示性具體實施例中，該防滲層可能具有閉孔結構(closed cell structure)或多微孔結構(microporous cell structure)。閉孔結構或無胞室(with no cells)之多微孔結構無法吸收液狀材料。
在本說明書之例示性具體實施例中，該施用層可能含有一泡沫體。特別地，該施用層可能含有由一或多選自於由聚酯、丙烯腈丁二烯橡膠(NBR)、苯乙烯-丁二烯橡膠(SBR)、天然橡膠 (NR)、聚氯乙烯、聚乙烯、乙烯乙酸乙烯酯丁基橡膠(EVA)、乳膠、矽氧烷、苯乙烯-異戊二烯-苯乙烯(SIS)、苯乙烯-乙烯-丁烯-苯乙烯(SEBS)、聚乙烯醇(PVA)、腈橡膠、丁基橡膠、氯平橡膠(Neoprene®)、聚烯烴及聚氨酯所組成之群組所製得之泡沫體，但未特別限制於此。該由矽氧烷製得之泡沫體可能係由一矽氧烷為主之彈性體製得者。該聚氨酯具體可能特別為濕式(wet-type)聚氨酯，更特別為以聚酯為主之聚氨酯、以聚醚為主之聚氨酯及由聚酯-聚醚混合之聚氨酯之一。
在一例示性具體實施例中，該泡沫體可能包括一膜狀泡沫體(membrane foam)或一植絨泡沫體(flock foam)。在本說明書之例示性具體實施例中，該膜狀泡沫體係一聚合物泡沫體，諸如以一膜披覆之橡膠、聚乙烯或聚氨酯，其通常在以膜包覆前具有比該泡沫體小之胞室大小(cell size)。在本說明書之例示性具體實施例中，該植絨泡沫體係一聚合物泡沫體，在其中已有附加纖維。該纖維可能為一或多選自於由棉、壓克力(acryl)、聚醯胺(polyamide)、尼龍(nylon)、聚酯、絲及嫘縈(rayon)所組成之群組。特別可以為棉、壓克力、聚醯胺、尼龍、聚酯、絲、與壓克力混紡之棉、與嫘縈混紡之棉、與棉混紡聚酯混紡之尼龍(nylon mixed with polyester mixed with cotton)或與聚酯混紡之壓克力。
在本說明書之例示性具體實施例中，該施用器之各層可能彼此融合(fused)。該融合方法沒有特別受限且包含熱封(thermal sealing)、雷射融合(laser fusion)、超音波融合(ultrasonic fusion)、高壓融合(high-pressure fusion)等。
在本說明書之例示性具體實施例中，該施用器可能在100-300 ºC被熱密封(thermally sealed)，特別為在130-250 ºC。意即，該防滲層可能由可在100-300 ºC(特別為130-250 ºC)被熱密封(接合)之材料製成。在本說明書中，所有施用層、防滲層、彈性層及覆蓋層皆可能以熱封法接合。
在一例示性具體實施例中，該施用層係導送及施用化妝品組合物至皮膚上之層，且該化妝品組合物係被該施用層吸收。同時，因為該化妝品組合物不會被該防滲層吸收，除了該施用層外，該化妝品組合物不會被該施用器吸收到其中。意即，被該施用層吸收之該化妝品組合物不會被該施用器進一步吸收到其中，且因此被導送至皮膚之該化妝品組合物之量會增加。
在本說明書之例示性具體實施例中，該彈性層可能由聚氨酯泡沫體形成，特別為乾式(dry-type)聚氨酯泡沫體、更特別為以聚酯為主之聚氨酯泡沫體，雖然沒有特別受限於此。該彈性層可能由具有每吋約100個孔洞(ppi)之泡沫體形成。
在本說明書之例示性具體實施例中，該覆蓋層可能由聚氨酯膜形成，特別為濕式聚氨酯膜，雖然沒有特別受限於此。
在本說明書之例示性具體實施例中，該施用器未特別受限，只要其為可導送化妝品組合物至皮膚者。例如，其可能為粉撲。
在本說明書之例示性具體實施例中，該化妝品組合物可能為液狀 化妝品組合物，雖然沒有特別受限於此。
在本說明書之例示性具體實施例中，該化妝品組合物可能為溶液(solution)、乳液(emulsion)或懸浮液(suspension)，雖然沒有受限於此。
在本說明書之例示性具體實施例中，該化妝品組合物可能為乳液，特別為油包水(water-in-oil，W/O)或水包油(oil-in-water，O/W)乳液，或分散液(dispersion)，特別為油性或水性分散液。
在本說明書之例示性具體實施例中，該化妝品組合物可能被配製成例如妝前乳(makeup primer)、妝前底霜(makeup base)、液狀或高黏性粉底(foundation)、兩用粉餅(twin cake)、遮瑕膏(concealer)、唇膏(lipstick)、唇蜜(lip gloss)、蜜粉(powder)、唇線筆(lip liner)、眉筆(eyebrow)、眼線筆(eye liner)、眼影(eye shadow)、腮紅(blusher)、防曬乳(sunscreen)、乳液(lotion)、乳霜(cream)、精華液(essence)等，雖然沒有受限於此。
本說明書之一態樣之化妝品組合物施用器可能被置於常被稱為粉餅(pact)之容器中，其包含作為該化妝品組合物施用器之粉撲、可容納其之下部件及具有一頂蓋之上部件，其有一反射鏡與其連接。
在一態樣中，本說明書提供一化妝品組合物施用器，其中該內容物係被防止被該彈性層吸收，且只被該施用層吸收並由其釋放出。因為該內容物未被該化妝品組合物施用器吸收，可解決內容物含量減少或潮濕所致不親膚感(unpleasant feeling)之問題。因此，提供一化妝品組合物施用器，其能一直維持柔軟觸感及彈性且對皮膚提供優良之導送。   [實施例]
在下文中，本說明書將藉由實施例詳細說明。然而，以下實施例僅用於說明目的，顯然地對本領域普通技術人員而言本說明書之範圍並不受實施例限制。   [製備實施例1]化妝品組合物之製備
含有油性成份、乳化劑、有機或無機防曬劑、顏料及水性成分之化妝品組合物(粉底)係如表1所述製備。該化妝品組合物具有28,000 cps (厘泊)之黏性。該黏性係使用布魯克非黏度計(Brookfield RVDV-III Ultra; Serial No. RY6521152)測量，設為轉軸編號63及轉軸轉速5 rpm或轉軸編號64及轉軸轉速12 rpm。 【表1】
Figure 105108228-A0304-0001
 [試驗實施例1] 包含防滲層之施用器對內容物之吸收
在不具防滲層之施用器(粉撲) (比較實施例1)或在具防滲層之施用器(粉撲) (實施例1)中加載15 g液狀內容物(化妝品組合物)後，藉由測量最大吸收重量比較對該內容物之吸收程度。對該內容物之導送率係被計算如下。結果顯示於表2中。 [方程式1] 內容物之導送率= 施用於皮膚上之內容物之量 (g) / 加載於施用器中之內容物之量施用器 (g) x 100
比較實施例1及實施例1之施用器除防滲層外有相同之施用層、彈性層及覆蓋層結構。特別該施用層係以具100-200 µm胞室大小(cell size)之濕式聚氨酯泡沫體形成。該防滲層係以具10-100 µm厚度之無胞室(cell-free)聚氨酯片材形成。該彈性層係以具2.5-4.5 mm厚度及250-400 µm胞室大小(cell size)之乾式聚氨酯泡沫體形成，其具有許多大型孔洞。該覆蓋層係以具0.3-1.5 mm厚度之聚氨酯片材形成，以避免手之污染及在掌中滑動。至於該施用器之硬度，「Asker F硬度(hardness)」係在該施用器吸收該組成物前使用Asker硬度計(F型)測量。   【表2】
Figure 105108228-A0304-0002
由表2，可看見該含有防滲層之施用器表現出低吸收率且內容物未被該彈性層吸收。   [試驗實施例2] 防滲層厚度之測定
對該防滲層厚度之效果進行測試。化妝效果、感覺及可加工性取決於防滲層之厚度進行評價。結果顯示於表3。
實施例2-5及比較實施例2之施用器係與實施例1相同，除了該防滲層之厚度外。   【表3】
Figure 105108228-A0304-0003
如表3所述，當該防滲層厚度大於3.0 mm時，該施用器因為加工不良使邊緣之接合處(joint)薄弱。而且，該施用器堅韌，且因為對皮膚之黏附性不佳使化妝效果無法令人滿意。因此，理想該防滲層具有0.01-3.0 mm之厚度。
當該防滲層之厚度為0.01-3.0 mm，該施用器對該內容物之持久性可被確保。因為該防滲層防止該施用器吸收該內容物，該施用器之彈性及親膚性可被維持。而且，由該施用器導送至皮膚之內容物量可被提高。
無
