Description
技术领域
本发明涉及化妆品技术领域，具体涉及一种光感防晒粉饼。
背景技术
粉饼，可用于脸部遮瑕、赋色、修饰。目前市售的粉饼具有较好防晒效果较少，并且在化妆室用粉饼化好比较满意的妆色，再到室外有强光照射下，妆色感觉很发白发亮，不自然。
发明内容
本发明的目的在于克服现有技术存在的不足之处而提供一种光感防晒粉饼。
为实现上述目的，本发明采取的技术方案为：一种光感防晒粉饼，包含以下重量百分含量的组分：光感二氧化钛4～16％和纳米氧化锌1～4％；所述光感二氧化钛为包含纳米级二氧化钛、氧化铁和氢化聚二甲基硅氧烷。
本发明所述光感防晒粉饼采用上述配比的光感二氧化钛和氧化锌复配，具有优异的防晒效果，并且会根据周围光照条件自动调节粉体颜色，避免妆色偏白发亮，化妆出来的妆色会随着光线强度改变而妆色改变。
所述光感二氧化钛采用纳米级二氧化钛、氧化铁和氢化聚二甲基硅氧烷配制而成，可以随着光照强度改变，原料的亮度也随之改变。添加至粉饼中时，光感二氧化钛可以采用聚二甲基硅氧烷进行表面处理。所述光感二氧化钛为纳米级的二氧化钛，优选粒径D50小于100nm，所述纳米氧化锌为纳米级氧化锌，优选粒径D50小于50nm。
优选地，所述光感防晒粉饼包含以下重量百分含量的组分：光感二氧化钛 6～10％和氧化锌1～3％。光感二氧化钛和纳米氧化锌以上述配比时，具有更佳的防晒效果，妆感在光线下更自然。更优选地，所述光感防晒粉饼包含以下重量百分含量的组分：光感二氧化钛8％和纳米氧化锌2％。
优选地，所述光感防晒粉饼还包含以下重量百分含量的组分：甲氧基肉桂酸乙基己酯0.5～2％、p-甲氧基肉桂酸异戊酯0.5～2％和二乙氨羟苯甲酰基苯甲酸己酯0.5～2％。本发明所述粉饼中还添加了上述三种化学防晒剂，这三种化学防晒剂与光感二氧化钛和纳米氧化锌复配，能使粉饼更具防晒效果。
更优选地，所述光感防晒粉饼还包含以下重量百分含量的组分：甲氧基肉桂酸乙基己酯1％、p-甲氧基肉桂酸异戊酯1％和二乙氨羟苯甲酰基苯甲酸己酯 1％。三种化学防晒剂采用上述配比时，防晒效果更佳。
优选地，所述光感二氧化钛包含以下重量百分含量的组分：纳米级二氧化钛92.15～96.03％、氧化铁0.97～4.85％和氢化聚二甲基硅氧烷3％。
优选地，所述光感防晒粉饼还包含以下重量百分含量的组分：滑石粉 30～50％、云母10～45％和硅石2～20％。所述粉饼中添加了上述配比的肤感调节剂，使粉饼具有较好的肤感和贴肤性。
优选地，所述光感防晒粉饼还包含甘油三(乙基己酸)酯4～16％。甘油三 (乙基己酸)酯在粉饼中的添加能增加粉饼的润肤性能。
优选地，所述光感防晒粉饼还包含生育酚乙酸酯0.02～0.5％。生育酚乙酸酯具有抗氧化作用，能避免粉饼中的油脂酸败氧化。
优选地，所述光感防晒粉饼还包含着色剂、粘合剂和防腐剂。
优选地，所述粘合剂为硬脂酸镁。
优选地，所述防腐剂为苯氧乙醇和乙基己基甘油的混合物。优选地，苯氧乙醇和乙基己基甘油的重量之比为：9：1。苯氧乙醇在80℃以下稳定，有抑制细菌效果，乙基己基甘油因其具有抗菌性，且稳定性强，与苯氧乙醇复配能增强其效果，使其可减少用量。
本发明的有益效果在于：本发明提供了一种光感防晒粉饼，本发明所述光感防晒粉饼采用二氧化钛和氧化锌复配，具有优异的防晒效果，并且会根据周围光照条件自动调节粉体颜色，避免妆色偏白发亮，化妆出来的妆色会随着光线强度改变而妆色改变。

2、试验部位选取后背，受试部位皮肤色泽均一，无色素痣及色斑等。
3、剂量约为2mg/cm2，准确均匀涂抹在受试皮肤。并在受试部位旁做好标记，受试皮肤约为30cm2。
4、发射近日光的UVA区连续光谱2～4小时，使用适当滤光片将波长短于320nm的紫外线和波长大于400nm的可见光、红外线过滤掉。
5、根据上述条件定期检测维护，记录定期检测结果，试验时MPPD (MPPD是指最小持续黑化量：即辐照后2～4小时在整个辐照部位产生轻微黑化所需的最小紫外线辐照量或最短时间)应选择在观察曝光后2～4小时之内的一个固定时间点进行，并使用公式 PFA＝MPPDp/MPPDu(式中MPPDp为测试产品保护的MPPD；MPPDu为测试产品未保护的MPPD)计算PFA平均值。
6、根据PFA值与与防晒时间的关系，PFA值小于2防护时间无、PFA值在2～3防护时间约为2～4小时、PFA值4～7防护时间约为4～8小时、 PFA值大于8时防护时间大于8小时。当PFA值大于8时，以抵抗 UVA时间＝PFA值*60计算，根据以上信息可大概得出抵抗UVA的防护力时间。
7、试验计算结果如下表2。
表2
| 项目 | PFA均值 | 抵抗UVA时间(分钟) |
| 实施例1 | 13 | 780 |
| 实施例2 | 10 | 600 |
| 实施例3 | 8 | 480 |
| 实施例4 | 11 | 660 |
| 实施例5 | 9 | 540 |
| 实施例6 | 8 | 480 |
| 实施例7 | 11 | 660 |
| 实施例8 | 8 | 480 |
| 对比例1 | 4 | 240 |
| 对比例2 | 8 | 480 |
实施例10
测试实施例1～8和对比例1～2所述粉饼的SPF值，测试方法为：
1、选取100名10～60岁健康人员，男女均可。
2、试验部位选取后背，受试部位皮肤色泽均一，无色素痣及色斑等。
3、剂量约为2mg/cm2，准确均匀涂抹在受试皮肤。并在受试部位旁做好标记，受试皮肤约为30cm2。
4、发射近日光的UVB区连续光谱20±4小时，使用适当滤光片将波长短于280nm的紫外线和波长大于320nm的长波紫外线、可见光、红外线过滤掉。
5、根据上述条件定期检测维护，记录定期检测结果，试验时MED(MED 是指最小红斑量)应选择在观察曝光后24±4小时之内的一个固定时间点进行，并使用公式SPF＝MEDp/MEDu(式中MEDp为测试产品保护的MED；MEDu为测试产品未保护的MED)计算SPF平均值。再根据SPF值计算出防护UVB时间。
6、由于个人肤质不一样防护UVB时间也不一样，选取15分钟出现最小红斑量。再根据值进行计算(分钟)＝SPF值*15。
7、试验计算结果如下表3。
表3
| 项目 | SPF均值 | 防护UVB时间(分钟) |
| 实施例1 | 45 | 675 |
| 实施例2 | 36 | 540 |
| 实施例3 | 38 | 570 |
| 实施例4 | 34 | 510 |
| 实施例5 | 31 | 465 |
| 实施例6 | 32 | 480 |
| 实施例7 | 31 | 465 |
| 实施例8 | 32 | 480 |
| 对比例1 | 44 | 660 |
| 对比例2 | 26 | 390 |
实施例11
为了验证本发明的上妆效果，做上妆测试粉饼妆效自然度。选取100名志愿者，年龄在20周岁-30周岁，分为10组，每组10人。由测试人员为志愿者清洁脸部，在同一环境静坐20分钟，再分别使用实施例1～8、对比例1、对比例2、进行上妆试验。再查看上妆的效果，并得出结论是否实用。如下表4。
表4
| 项目 | 上妆效果 | 结论 |
| 实施例1 | 取粉容易、上妆自然 | 实用 |
| 实施例2 | 取粉容易、上妆自然 | 实用 |
| 实施例3 | 取粉容易、上妆自然 | 实用 |
| 实施例4 | 取粉容易、上妆自然 | 实用 |
| 实施例5 | 取粉容易、上妆自然 | 实用 |
| 实施例6 | 取粉容易、上妆自然 | 实用 |
| 实施例7 | 取粉容易、上妆自然 | 实用 |
| 实施例8 | 取粉容易、上妆自然 | 实用 |
| 对比例1 | 取粉容易、上妆自然 | 实用 |
| 对比例2 | 取粉困难、上妆卡粉 | 不实用 |
实施例12
依据实施例9～11的试验数据，防护UVA、UVB的时间，以防护低值来计算总防护时间，得出以下测试结果，如表5。
表5
从表5可以看出，光感二氧化钛和氧化锌复配的防晒效果比单独使用的效果更佳，光感二氧化钛和氧化锌采用实施例1的配比复配时防晒效果更佳。光感二氧化钛的添加能够使粉饼使用效果更自然，三种化学防晒剂与光感二氧化钛和纳米氧化锌复配，能使粉饼更具防晒效果。
最后所应当说明的是，以上实施例仅用以说明本发明的技术方案而非对本发明保护范围的限制，尽管参照较佳实施例对本发明作了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的实质和范围。
