Description

一种水基电子烟烟液 技术领域
本申请涉及电子烟烟液领域，尤其涉及一种水基电子烟烟液。
背景技术
目前市面上的电子烟主成分为甘油和丙二醇，甘油主要起到雾化发烟的作用。由于甘油溶解性差，流动性弱，粘度高，必须在雾化剂中加入丙二醇。丙二醇的作用是溶解香精香料，提升雾化剂的流动性，同时也能起到雾化发烟的作用。传统上，甘油被认为对人体是安全的。《食品添加剂使用标准》(GB 2760-2014)规定甘油可用作多种用途，每日最高限量为按生产需要使用。但丙二醇并不安全，GB2760-2014中只允许了两个领域的用途：生湿面制品(如面条、饺子皮、馄饨皮、烧麦皮)和糕点，每日最高限量分别为：1.5和3.0g/Kg。
传统上甘油被认为有甜腻感，而且抽吸起来化学感较重，和传统香烟比起来抽吸感比较难使用户接受。
主要组成物为甘油和丙二醇的电子烟烟液粘度和沸点较高，比较费电的同时还容易在雾化器上产生结碳。当雾化温度大于200℃时，经检测，甘油和丙二醇还会产生醇酮类化合物，危害用户的健康。
此外，长久以来的认识中，水对传统的以甘油和丙二醇为主要雾化剂的电子烟油雾化效果有很大的影响，当电子烟油中含水量大于10％，电子烟雾化量显著降低。
因此，有必要研发出一种全新的水基电子烟烟液，其中成分少量包含或甚至不包含丙二醇和甘油，在保证一定发烟量的情况下，提升电子烟烟液的安全性和抽吸口感，并具有更低的粘度和沸点来保护烟具。
发明内容
本发明要解决的技术问题是克服现有技术的不足，提供一种环保、安全性高、口感舒适，发烟效果好且粘度低的电子烟烟油。
为解决上述技术问题，本发明采用以下技术方案：
一种水基电子烟烟液，包括以下质量份的组分：水5份～60份；常温下为固体、溶于水的烟雾提供成分5份～50份；和甘油0份～30份。所述烟雾提供成分为糖醇。 在传统的认识中，通常认为糖醇是结晶形态的固体，没有流动性，不能用作电子烟雾化剂；同时，传统认识中，水对传统的以甘油和丙二醇为主要雾化剂的电子烟油雾化效果有很大的影响，当电子烟油中含水量大于10％，电子烟雾化量显著降低。本发明在调配水基电子烟烟液时，用糖醇作为烟雾提供成分溶于水作为电子烟烟液的主要雾化成分。
进一步地，所述水基电子烟烟液拥有低粘度，本发明中所说的低粘度是指在常温常压下粘度低于甘油+丙二醇烟油粘度，具体地粘度小于或等于200mPa·s，或者小于或等于150mPa·s，或者小于或等于100mPa·s，或者小于或等于75mPa·s，或者小于或等于50mPa·s，或者小于或等于25mPa·s，或者小于或等于20mPa·s，或者小于或等于15mPa·s，或者小于或等于12mPa·s，或者大于或等于1.1mPa·s。本发明在大量实验的基础上发现，水能够降低电子烟烟液的粘度，因而水基电子烟液的粘度小于甘油丙二醇烟油，可以在更低的功率下使用，减少发热功率，避免了发热丝温度高易导致碳化结焦同时可以延长电池使用时间。
进一步地，所述水基电子烟烟液拥有低沸点，本发明中所说的低粘度是指在常温常压下相对于甘油丙二醇类烟油具有较低沸点，具体地沸点小于或等于180℃，或者小于或等于160℃，或者小于或等于140℃，或者小于或等于120℃，或者小于或等于110℃，或者大于或等于103℃。本发明在大量实验的基础上发现，包含糖醇的水基电子烟的烟点小于甘油+丙二醇烟油，可以在更低的功率下使用，减少发热功率，避免了发热丝温度高易导致碳化结焦同时可以延长电池使用时间。
进一步地，所述水基电子烟烟液拥有高比热容，本发明中所说的高比热容是指在常温常压下相对于甘油丙二醇类烟油具有较高比热容，具体地沸点大于或等于2.8J/(g·℃)，或者大于或等于2.8J/(g·℃)，或者大于或等于2.9J/(g·℃)，或者大于或等于3.0J/(g·℃)，或者大于或等于3.1J/(g·℃)，或者大于或等于3.2J/(g·℃)，或者大于或等于3.3J/(g·℃)，或者大于或等于3.4J/(g·℃)，或者大于或等于3.5J/(g·℃)。本发明在大量实验的基础上发现，包含糖醇的水基电子烟的比热容大于甘油+丙二醇烟油，可以防止电子烟加热过快，导致有机成分裂解产生大量有害物质。
进一步地，所述水基电子烟烟液在抽吸时的每口平均雾化量大于或等于0.80ug/口，所述雾化量为捕集所得气溶胶的重量。本发明通过研究发现，包含将糖醇溶于水中组成的混合物的电子烟烟液，拥有良好的发烟效果，其烟雾量不弱于甘油和丙二醇的混合物。
进一步地，所述水基电子烟烟液在抽吸时的每口平均甲醛含量分别小于或等于1.00ug/口和乙醛含量小于或等于0.5ug/口。本发明通过大量实验发现，水基电子烟雾化剂在羰基化合物的生成上，比传统电子烟烟液具有更好的安全性。
进一步地，所述水基电子烟烟液由以下质量份的组分组成：糖醇10份～50份；甘油0份～30份；和水20份～50份。
进一步地，所述水基电子烟烟液由以下质量份的组分组成：糖醇20份～30份；甘油0份～10份；和水20份～40份。
进一步地，所述糖醇选自赤藓糖醇、木糖醇、甘露糖醇和山梨糖醇中的至少一种；优选赤藓糖醇和木糖醇的混合物，所述赤藓糖醇和木糖醇的质量比为1∶1～1∶4；更优选赤藓糖醇、山梨糖醇和木糖醇的混合物，所述赤藓糖醇和木糖醇的质量比为1∶1～1∶4，所述赤藓糖醇和山梨糖醇的质量比为1∶1～1∶4。本发明经过大量实验发现，当糖醇选用质量比1∶1～1∶4之间的赤藓糖醇和木糖醇的混合物，特别时另外加入和赤藓糖醇质量比为1：1～1∶4之间的山梨糖醇时，所述水基电子烟的发烟效果、物理性能、口感口味均达到最优平衡。在本发明中，以水代替丙二醇作为雾化剂中的溶剂部分，和丙二醇相比，水明显具有更优的安全性。赤藓糖醇、木糖醇、甘露糖醇、山梨糖醇都是常用的代糖，并受到了消费者的普遍接受，其安全性也接受了长时间的考验。因此本发明的电子烟即使发生误食也不会产生严重后果。
进一步地，所述的水基电子烟烟液包括用于增加香气的物质和/或烟草提取物，所述用于增加香气的物质包括烟用香精和/或烟用香料，优选质量组分为0.01份～10份，所述烟草提取物优选重量份组分0份～20份。香精一般为液态，香料一般为固态，香精和/或香料的溶剂以水为主，为了促溶和抑制霉变，可加入少量丙二醇或乙醇作为促溶剂或霉变抑制剂。但以不影响吸味或给消费者带来酒醉效应为限。
一种水基电子烟烟液，包括以下质量份的组分：水5份～60份；常温下为固体、溶于水的烟雾提供成分5份～50份。所述烟雾提供成分为糖醇。
进一步地，所述水基电子烟液不包括丙二醇。因丙二醇及其加热后的生成物对人体的不良影响，本发明在经过大量实验之后，调整配比获得不含丙二醇的水基电子烟烟液，在获得良好发烟性能的同时，还能比传统烟液获得更高的安全性。另外在口感上，糖醇能够在一定程度上压制甘油的不良气息。在不可避免需要使用到丙二醇作为促溶剂或霉变抑制剂等功能性助剂时，所述水基电子烟液包括丙二醇小于或等于5份。
进一步地，所述水基电子烟液包括甘油小于或等于30份，或者小于或等于25份，或者小于或等于20份，或者小于或等于15份，或者小于或等于15份，或者小于或等于10份，或者小于或等于5份，优选不包括甘油和丙二醇。本发明在大量实验的基础上发现，甘油和丙二醇除了会在雾化后生成羰基物质之外，还会有很浓厚的甜腻感与化学气息，因此为了提高烟雾口感质量，将甘油和丙二醇剔除出本水基电子烟烟液的组分。
进一步地，在持续抽吸的过程中，所述水基电子烟烟液拥有稳定的雾化效果。本发明经过大量实验测定发现，和传统电子烟烟液相比，无论是包不包含甘油的无丙二醇水基电子烟烟液都拥有非常稳定的发烟效果。
进一步地，所述水基电子烟烟液的雾化效果浮动值为S EPPECT，所述水基电子烟烟液的抽吸口数为n，所述水基电子烟烟液第i口的对应雾化量为S i，所述水基电子烟烟液的平均每口雾化量为
Figure PCTCN2020073137-appb-000001
上述参数满足
Figure PCTCN2020073137-appb-000002
的关系。通过上述公式可以获得水基电子烟烟液的雾化效果浮动值。经过大量实验测定之后可以确认，无论是包不包含甘油的无丙二醇水基电子烟烟液的雾化效果都非常稳定，雾化效果浮动值始终保持在0.1以下。
进一步地，所述水和烟雾提供成分的质量比为1∶4～4∶1；进一步地，所述水和烟雾提供成分的质量比为1∶4～1∶1。当水含量过高时，烟雾提供成分无法帮助水汽形成足够的烟雾；当烟雾提供成分过高时，溶液流动性较差，容易产生结晶，不利于电子烟正常运作。
与现有技术相比，本发明的优点在于：
1、以糖醇和水为主要成分的雾化剂设计方案，本配方具有比传统甘油+丙二醇的雾化剂更优的安全性和抽吸口感。
2、以糖醇和水为主要成分的雾化剂设计方案，新配方具有比传统配方更低的粘度和沸点，能够减少结碳，延长电池工作时间，减少烟具生产成本。
3、本配方具有成本低廉，生产简单的优势。

羰基化合物检测实验一
在电子烟研究领域，通常采用测量气溶胶中醛酮物质含量的方法，衡量烟液的安全性。
1)实验选取的样品为：丙二醇、甘油、空白雾化剂、市售电子烟油样品70(云端一号电子烟油)、市售电子烟油样品82(黄鹤楼蒸汽烟油)、实施例1步骤1所得混合物样品(代号S1，共两个样，分别为S1-1和S1-2)，实施例1步骤2所得的电子烟烟液(代号S2，共两个样，分别为S2-1和S2-2)。
2)测试方法
2.1)直线型吸烟机测试步骤：分别将上述样品灌注于电子烟具，以直线式吸烟机(型号为：SM450)按照钟型曲线的条件进行抽吸，抽吸时，电子烟器具外接恒压源，4.5V。抽吸模式抽吸曲线为方波曲线，抽吸容量55mL，抽吸时间为每口3秒，间隔30秒，抽吸30口。烟雾量采用2片45毫米的剑桥玻璃纤维滤片进行捕集(含醛酮衍生化试剂)。
2.2)高效液相色谱检测步骤：采用行业标准方法《卷烟卷烟主流烟气中主要羰基化合物的测定》测定捕集物中主要羰基化合物的含量。
2.3)电子烟与吸烟机同步步骤：传统雾化器(电阻丝+导油棉)利用稳压电源模块(最大电压6.2V，测试电压4V)与吸烟机同步；超声波雾化器无外接装置，连接自带电池，手动按开关与吸烟机同步。
2.4)验证是否需要吸收瓶步骤：在空白雾化剂中加入较高含量的醛酮标准品，在上述实验方法的基础上，通过在吸烟机上连接带有10ml醛酮衍生化试剂的吸收瓶进行实验，实验结果表明，在吸收瓶衍生液中未检测出醛酮。所以，吸烟机捕集器在2片滤片的情况下可以全部收集30口电子烟烟气中的醛酮化合物，无需再接吸收瓶。
测试结果如下：

从表2-4的对比可知，本发明的水基电子烟雾化剂或水基电子烟油雾化后未发现羰基化合物或其他有害物质。和普通电子烟雾化剂气相成分对比，本水基雾化剂具有更好的安全性。
烟雾捕集测试一
将本实施例6的电子烟烟液灌注于电子烟具，以直线式吸烟机(型号为：SM450)按照钟型曲线的条件进行抽吸，抽吸时，电子烟器具外接恒压源，4.5V。抽吸模式抽吸曲线为方波曲线，抽吸时间为每口3秒，间隔30秒。
烟雾量采用45毫米的剑桥玻璃纤维滤片进行捕集，使用称重法测量剑桥滤片捕集的物质。除了水以外的物质，都会被剑桥滤片捕集，形成烟雾。
本实施例的烟雾捕集数据详见表4。
表5烟雾捕集测试一的烟雾捕集数据
  滤片捕集的重量(mg) 仪器失重(mg) 捕集率
第一个30口 35.9 53.7 66.85％
第二个30口 35 50.7 69.03％
第三个30口 35.2 50.4 69.84％
第四个30口 35.4 50.3 70.38％
第五个30口 35.2 50.4 69.84％
第六个30口 35.5 50.4 70.44％
第七个30口 35.4 50.6 69.96％
滤片捕集的重量可以认为是雾化剂受热后的气相成分，即烟雾部分。仪器失重为电子烟具中受热挥发的烟液部分。由于水不会被滤片捕集，因而滤片捕集量少于仪器 失重量。综合两者的数据，可以计算出捕集率。和烟液的成分配比比对，可以发现捕集率正比于烟液中的溶质部分。可见，本发明的水基电子烟液的雾化量正比于烟液中的溶质部分。
采用相同的电子烟器具，使用纯甘油构成的电子烟油，使用同样的吸烟机，实验前后称量滤片和烟具的重量，获得滤片捕集和烟具失重数据，如表5所示。
表6 纯甘油的烟雾捕集数据
Figure PCTCN2020073137-appb-000006
由于甘油易吸收空气中的水分，导致滤片捕集量高于仪器的失重数据。
从表5和表6的对比可知，本发明的水基烟液具有和甘油类似的雾化量，烟液中的溶质含量为60％的条件下，水基烟液的雾化量在同等条件下，是纯甘油烟油的60％。
将本实施例1-52的电子烟烟液加入普通电子烟雾化器，正常抽吸，产生肉眼可见的淡蓝色烟雾。连续抽吸，烟雾量没有明显减少，口味保持稳定。实验表明，和甘油-丙二醇1∶1的烟油相比，含水率为50％的本发明的雾化剂其捕集物重量也接近甘油-丙二醇1∶1的烟油捕集重量的50％。肉眼观察抽吸时产生的烟雾量，含水率为50％的本发明的雾化剂其烟雾量也接近甘油-丙二醇1∶1的烟油烟雾量的50％。
羰基化合物检测实验二
挑选以下实施例的水基电子烟液，收集其气溶胶，分析气溶胶中每口醛酮含量，将其和传统甘油、丙二醇电子烟油的数据比对，具体的数据见表7:

感官评价测试一
除了用称重法比较烟雾量外，肉眼观察，主观评价的方法也用来评价水基电子烟液的烟雾量。测试本发明实施例所述的电子烟液的感官质量，感官质量评价标准如表8所示，包括烟雾量、甜腻感、刺激性、杂气、余味5个评价项目，每个评价项目的最大标度均为9份，各评价项目均以1分为计分单位。

烟雾捕集测试二
将配置好的实施例20、30和35以及对比例1-8的电子烟液分别灌入电子烟器具储油仓，上电子烟吸烟机抽吸，以剑桥滤片捕集气溶胶。通过称重法，精确称量前50口捕集前后剑桥滤片的重量变化，得到平均每口中气溶胶的重量。将实施例20、30和35以及对比例1-8的电子烟液的数据进行比对，用来衡量水基电子烟液的烟雾量。具体的数据见表10:

对比例3 0.21
对比例4 0.51
对比例5 0.69
对比例6 1.21
对比例7 1.82
对比例8 1.71
根据表10的数据，水在传统电子烟液中的比例不能过高，否则会明显的降低烟雾量，影响抽吸品质，而在水中添加烟雾提供成分则可明显提升烟雾量。
选取实施例20、30、35，将配置的电子烟液，灌入电子烟器具储油仓，以电子烟吸烟机抽吸，剑桥滤片捕集气溶胶。
通过称重法，精确称量捕集前后剑桥滤片的重量变化，得到每口中气溶胶的重量。在同样实验条件下测量对比例8的数据，比较两组数据，用来衡量水基电子烟液的烟雾量。具体的数据见表11：
表11：水基电子烟液和传统电子烟油平均雾化量(ug/口)的比较
Figure PCTCN2020073137-appb-000009
表11的数据证明加入发烟剂，显著的提升了水基电子烟液的烟雾量。其数据仅略低于传统电子烟油。在小烟器具上，直接抽吸，肉眼观察，其烟雾量在可以接受的水平。
根据表11的数据和评吸实验，获得如下结论：水基电子烟液的烟雾量略小于传统甘油、丙二醇电子烟油。适用于追求中小烟雾量的吸烟人群。
在上述实验过程中，以水基电子烟烟液的雾化效果浮动值为S EPPECT，水基电子烟烟液的抽吸口数为n，水基电子烟烟液第i口的对应雾化量为S i，水基电子烟烟液的平均每口雾化量为

发现实施例20、30、35的上述参数均满足
Figure PCTCN2020073137-appb-000011
的关系。通过上述公式可以获得水基电子烟烟液的雾化效果浮动值。经过大量实验测定之后可以确认，无论是包不包含甘油的无丙二醇水基电子烟烟液的雾化效果都非常稳定，雾化效果浮动值始终保持在0.1以下。
电子烟液比热容检测
选取实施例25、26、27和对比例8的电子烟烟液，分别测定其常温常压下的比热容。
表12：水基电子烟液和传统烟油比热容对比
编号 比热容/(J/(g·℃))
实施例25 3.40
实施例26 3.50
实施例27 3.32
对比例8 2.57
从表12可以看出，各种配方的水基烟液的比热容相对于传统电子烟烟油较高，可以防止电子烟加热过快，导致有机成分裂解产生大量有害物质。
电子烟液沸点检测
选取以下实施例和对比例8的电子烟烟液，测定其常压下的沸点。
表13：水基电子烟液和传统烟油沸点对比
编号 沸点/(℃)
实施例12 106

实施例55 108
实施例56 103
实施例57 111
实施例58 108
实施例59 104
对比例8 197
从表13可以看出，各种配方的水基烟液沸点比较接近，明显小于传统电子烟烟油。水基烟液沸点更低，可以在更低的受热温度，更少的供热量下雾化形成气溶胶。
电子烟液粘度检测
选取以下实施例和对比例8的电子烟烟液，测定其常温常压下的粘度。

实施例57 15
实施例58 7
实施例59 4
对比例8 250
从表14可以看出，从水基烟液和传统电子烟烟油的理化性质比对可以得出，水基烟液具有更低的粘度，水基烟液流动性更好，能够在器具设计方面带来诸多优势。
发烟雾化测定
分别将按照表14中实施例和对比例8的物质比例配制电子烟液样品，然后将所述电子烟液分别注入低频振荡器具中，让所述电子烟液充分静置后打开上述器具，然后观测设备的发烟情况，如果设备产生持续且明显的烟雾，则可以认为电子烟液是可以产生烟雾的，则标记为√，如果设备不能产生持续且明显的烟雾，则可以认为电子烟液不能产生烟雾，则标记为×。将测试结果依次记录在表14中，得到如下测试结果：

从表15的对比可知，与普通电子烟烟油相比，本发明的电子烟液具有更低的粘度，能够在低频振荡器具发烟，由于低频振荡器具工作功率较低，从而可以降低器具使用的能耗，延迟器具使用的时间，提高用户使用器具的便利性。此外，由于低频振荡器具工作功率较低，振荡的机械运动较慢，因此在工作过程中产生的热量较少，有着相比高频振荡更低的工作温度，从而降低烟气中的有害物质，比普通电子烟烟油具有更好的安全性。
将上述实施例25、26和27的低粘度、低沸点、高比热容的电子烟烟液置于全新的电子烟器具中，分别进行5轮由半注满到干烧为止的连续加热使用，均未发现碳化结焦现象。将对比例8的电子烟烟液置于全新的电子烟器具中同样进行5轮由半注满到干烧为止的连续加热使用，发现碳化结焦现象。
