[0019] 本发明的护肤组合物以线型聚甲基苯基硅氧烷、 网状型聚甲基苯基硅氧烷、 硅 橡胶和聚二甲基硅氧烷复配形成的聚硅氧烷弹性体复配物、 聚二甲基硅氧烷和 聚醚改性聚硅氧烷五种聚硅氧烷作为关键的基质组分, 并配以单甘酯、 十八醇 、 吐温 -60和水, 形成本发明的护肤组合物。 由于以上组分, 尤其是五种聚硅氧 烷组分的相容和协同作用, 使得本发明的护肤组合物表现出能高效阻挡外界环 境侵害、 能显著修复改善肤质、 手感爽滑不粘腻的优良特性。
[0020] 更重要的是, 与一般的线型与网络型聚硅氧烷复配单纯用于改善化妆品手感如 爽滑性, 粘腻感, 弹性触感和皮肤涂膜强度的设计目的不同, 本发明的护肤组 合物, 尤其是线型聚甲基苯基硅氧烷与网状型聚甲基苯基硅氧烷的组合, 能形 成一种全新的生理活性成分微粒的空间分散承载与防护结构; 能显著增强生理 活性成分微粒的体系相容性与悬浮分散稳定性, 增强生理活性成分的缓释控制 能力以及真皮渗透性; 从而改善生理活性成分的生物利用度, 有效防止或减少 生理活性成份在皮肤表面集中聚集诱发对人体有负面影响的潜在致敏反应, 防 止或减少环境对其生物活性有负面影响的任何化学改变, 例如氧化、 氢化和异 构化, 尤其是 UV紫外线诱导的活性成分分解; 增强护肤品生理活性成分的效能 和整体配方的稳定性。
[0021]
[0022] 具体实施方式 [0023] 下面通过具体实施方式对本发明作进一步详细说明。
[0024] 本发明称为护肤组合物, 应当理解, 是指用于皮肤防护的组合物。 然而, 本发 明对于组合物的具体形式比如包装形式和施用形式没有特别限定, 并且本发明 的护肤组合物虽然优选是那种直接涂覆到人体或其它动物体的护肤品, 但是本 发明并不局限于直接涂覆到人体的护肤品, 也可以包括对人体间接起到防护作 用的组合物。 典型但非限定性的护肤组合物的例子, 比如膏霜瓶装、 软管包装 、 走珠包装、 乳液喷剂包装、 面膜或湿纸巾包装或织物表面预涂布等形式的组 合物。
[0025] 本发明的突出特点在于, 以线型聚甲基苯基硅氧烷、 网状型聚甲基苯基硅氧烷 、 硅橡胶和聚二甲基硅氧烷复配形成的聚硅氧烷弹性体复配物、 聚二甲基硅氧 烷和聚醚改性聚硅氧烷五种聚硅氧烷作为关键的基质组分, 用于形成护肤组合 物。 这五种聚硅氧烷彼此具有良好的相容和协同作用, 并且与其他组分具有良 好的相容和协同作用。 因此, 本发明的护肤组合物表现出良好的阻挡外界环境 侵害、 能显著改善肤质、 手感爽滑不粘腻的优良特性。 对生理活性成分具有良 好的体系相容性和悬浮分散稳定性、 缓释控制能力和真皮渗透性、 良好的生物 利用度、 防止或减少生理活性成份对人体的负面影响、 以及保护生理活性成份 不受外界不利环境影响。
[0026] 需要特别强调的是, 改善肤质、 手感爽滑不粘腻仅是本发明的护肤组合物的一 方面的特性。 从本发明的设计构思出发, 本发明最关键的构思之一在于: 采用 线型聚甲基苯基硅氧烷与网状型聚甲基苯基硅氧烷的组合, 能形成一种全新的 生理活性成分微粒的空间分散承载与防护结构; 能显著增强生理活性成分微粒 的体系相容性与悬浮分散稳定性, 增强生理活性成分的缓释控制能力以及真皮 渗透性; 从而改善生理活性成分的生物利用度, 有效防止或减少生理活性成份 在皮肤表面集中聚集诱发对人体有负面影响的潜在致敏反应, 防止或减少环境 对其生物活性有负面影响的任何化学改变, 例如氧化、 氢化和异构化, 尤其是 U V紫外线诱导的活性成分分解; 增强护肤品生理活性成分的效能和整体配方的稳 定性。
[0027] 线型聚甲基苯基硅氧烷和网状型聚甲基苯基硅氧烷组合使用, 涉及聚合物分子 链与分散其间的生理活性成分微粒这两个微观体系复合协同, 通过改变各自的 行为, 从而形成全新可调的生理活性成分微粒的空间分散承载与防护体系, 具 体的优势说明如下:
[0028] 线型聚甲基苯基硅氧烷对生理活性成分的优异相容性, 表现在: 生理活性成分 微粒作为线型聚甲基苯基硅氧烷各链段之间的缠结点 (在分子热运动的作用下 , 缠结点处于不断解体和重建的动态平衡中, 使得整个线型聚甲基苯基硅氧烷 与生理活性成分形成具有瞬变的空间网状结构) ; 从空间位阻效应角度分析, 线型聚甲基苯基硅氧烷分子链间可以实现紧密的堆积, 其空间位阻效应较大, 其所起到的支撑强度、 粘度和悬浮稳定性显著提高, 同吋线型聚甲基苯基硅氧 烷相对网状型聚甲基苯基硅氧烷, 具备更轻快的皮肤表面铺展能力。
[0029] 网状型聚甲基苯基硅氧烷在兼顾线型聚甲基苯基硅氧烷的特点的同吋, 因其结 构中存在 (网状型) 支链结构, 使其高分子长链间的缠绕比线型大, 故具有搅 拌与剪切变稀效应, 属于非牛顿液体; 且高分子长链间的缠绕大, 使生理活性 成分微粒的缠结相容能力更强。 从空间位阻效应角度分析, 网状型聚甲基苯基 硅氧烷分子链间 (包括网状型支链结构的大小链段间) 可以实现非常紧密的三 维和共平面堆积, 其空间位阻效应很大。 具体表现在, 在搅拌与剪切等典型护 肤品加工工艺中: (1) 最终呈现为生理活性成分微粒的优异分散性; (2) 高 分子长链间的缠绕大, 各个链段分段运动在外力作用下, 高分子链顺外力场有 所伸展伴随一定量的高弹形变, 这部分高弹形变是可逆的, 外力消失后, 高分 子链又蜷曲起来, 因而生理活性成分微粒作为缠结点, 在搅拌与剪切中, 呈现 出与网状型聚甲基苯基硅氧烷更均匀与更牢固的结合, 同吋网状型聚甲基苯基 硅氧烷在皮肤表面的成膜牢度优于线型聚甲基苯基硅氧烷; (3) 综合线型聚甲 基苯基硅氧烷和网状型聚甲基苯基硅氧烷的各自优点, 按合适比例组合, 能形 成一种全新的生理活性成分微粒的空间分散承载与防护结构, 且纳 (微) 米颗 粒分散的稳定性可以调节。
[0030] 此外, 采用线性和网状型聚甲基苯基硅氧烷为主的高含量聚硅氧烷作为基质材 料, 使得基质具有很好的相容性和强渗透力。 依靠这样的基质材料, 能够使尿 囊素和透明质酸等传统护肤化合物, 以及其他生理活性成分等可以在皮肤发挥 营养功能和提高皮肤抵御力的功能, 借助基质的特殊渗透力和相容性, 从皮肤 表皮角质层进入真皮层从而发挥真正作用。 与之相反, 相容性和渗透能力不好 的基质没有能力承担起这样的作用。
[0031] 此外, 线性和网状型聚甲基苯基硅氧烷, 兼具优异的射线辐照吸收能力, 使得 以线性和网状型聚甲基苯基硅氧烷为主体的基质材料, 具有优异的环境射线 ( 尤其是 UV紫外线) 屏蔽防护能力。 依靠这样的基质材料, 能防止或减少不利环 境对分散在其中的生理活性成分微粒的活性削弱或其他有负面影响的任何化学 改变, 例如氧化、 氢化和异构化等, 尤其是 UV紫外线诱导的活性成分的分解; 增强了护肤品生理活性成分的效能和整体配方的稳定性。
[0032] 聚硅氧烷弹性体复配物, 是由相对高分子量的硅橡胶和相对低分子量的聚二甲 基硅氧烷复配形成的复配物, 由于具有高聚合度弹性体和低聚合度的高分子链 间长短相配合, 能最大程度地限制油腻感, 能调节膏体粘度, 使之更细腻; 能 保持持久干爽与丝绸般的滑爽。 需要说明的是, 该复配物中硅橡胶与聚二甲基 硅氧烷的含量可以在很宽泛的范围内变动, 典型但非限定性的含量比例如 1 : 99 -99: 1, 优选 5: 95-95: 5, 更优选 10: 90-90: 10, 又更优选 20: 80-80: 20。
[0033] 聚二甲基硅氧烷, 能限制油份的油腻感和低表面张力和憎水性, 能帮助其他成 份的吸收和扩散作用, 且易产生润滑感。
[0034] 聚醚改性聚硅氧烷, 在水的乳化体系中可溶, 能与非离子表面活性剂组合成复 合型非离子乳化剂, 可以得到稳定的乳液体系, 并使护肤组合物性能稳定, 透 明性与爽滑性增加。
[0035] 本发明中恰当选择的上述五种聚硅氧烷, 不但在性能上具有良好的相容、 协同 和互补作用, 而且各种聚硅氧烷在组分配比上比例恰当, 有利于各自性能的发 挥和互相之间性能的协同。
[0036] 具体而言, 按照重量百分数计上述护肤组合物包含: 线型聚甲基苯基硅氧烷 7- 12% , 网状型聚甲基苯基硅氧烷 7-14%, 硅橡胶和聚二甲基硅氧烷复配形成的聚 硅氧烷弹性体复配物 2-6%, 聚二甲基硅氧烷 2-6%, 聚醚改性聚硅氧烷 1-4%。 发 明人还发现, 上述五种聚硅氧烷的总含量为 27%以上能够具有更加优异的性能。
[0037] 除了上述五种聚硅氧烷以外, 本发明的护肤组合物还含有单甘酯、 十八醇、 吐 温 -60, 和水。
[0038] 单甘酯, 或称单硬酸酯甘油酯, 涂于皮肤具有光滑与柔软的感觉; 既可增加乳 膏体的稠度和硬度, 又可增加乳膏吸水能力, 还可以起辅助乳化的作用。
[0039] 采用液态脂质与固态脂质 (单甘酯) , 可以形成生理活性成分的微纳米载体系 统。 固态脂质和液态脂质的混合物, 在常温下呈现固态, 随液态脂质加入固态 脂质中后, 可以改变固态脂质的结晶形式, 产生晶格缺陷, 从而可以容纳生理 活性成分, 增加生理活性成分的负载量, 避免生理活性成分在存储过程中发生 的渗漏。
[0040] 十八醇, 常用作膏体憎稠剂; 膏体细腻光亮, 手感柔和。
[0041] 吐温 -60, 是一种非离子表面活性剂; 与聚醚改性聚硅氧烷、 单甘酯等组成复 合型非离子乳化剂, 也起到增溶剂、 润湿剂的作用。
[0042] 本发明中, 上述单甘酯、 十八醇和吐温 -60在组分配比上比例恰当, 有利于各 自性能的发挥以及与上述五种聚硅氧烷之间的性能的协同。 具体而言, 按照重 量百分数计上述护肤组合物包含: 单甘酯 3-5%, 十八醇 4-7%, P土温 -60 1-3%。
[0043] 本发明的护肤组合物中各种组分的含量允许在上述规定的范围内变化, 而对性 能没有显著的影响。 然而, 超出上述范围可能对性能有显著的影响。
[0044] 具体而言, 本发明的护肤组合物中各种组分的含量, 按照重量百分数计:

[0053] 与现有技术相比, 具有上述组成和含量的护肤组合物的优势在于:
[0054] 首先, 与一般的线型与网络型聚硅氧烷复配单纯用于改善化妆品手感如爽滑性 , 粘腻感, 弹性触感和皮肤涂膜强度的设计目的不同, 本发明的护肤组合物, 尤其是线型聚甲基苯基硅氧烷与网状型聚甲基苯基硅氧烷的组合, 能形成一种 全新的生理活性成分微粒的空间分散承载与防护结构; 能显著增强生理活性成 分微粒的体系相容性与悬浮分散稳定性, 增强生理活性成分的缓释控制能力以 及真皮渗透性; 从而改善生理活性成分的生物利用度, 有效防止或减少生理活 性成份在皮肤表面集中聚集诱发对人体有负面影响的潜在致敏反应, 防止或减 少不利环境对分散在其中的生理活性成分微粒的活性削弱或其他有负面影响的 任何化学改变, 例如氧化、 氢化和异构化, 尤其是 UV紫外线诱导的活性成分分 解; 增强护肤品生理活性成分的效能和整体配方的稳定性。
[0055] 其次, 本发明的护肤组合物采用世界公认并经中国医学科学院等单位检测证实 为无生理毒性和任何刺激性的五种聚硅氧烷作为主要组份 (基质) , 与在化妆 品行业中已通过安全评价的其他原料组份制作而成, 故本护肤组合物具有高度 安全性, 对婴儿、 儿童幼嫩的皮肤无任何刺激性, 可适合不同年齢、 不同肤质 、 不同性别的人群, 在身体任何部位且一年四季都可以使用。 值得重视的是, 并非所有的硅氧烷都具备无毒无刺激的特点, 例如, 八甲基环四硅氧烷、 十甲 基环五硅氧烷 (环戊甲基硅氧烷) 等非聚合体的硅氧烷, 它们虽然也能给化妆 品带来爽滑不油腻, 以及丝绸般的手感, 但其潜在的毒性与刺激作用已经引起 业界重视。 与之比较, 本发明的护肤组合物采用的都是有一定聚合度的完全没 有毒性和刺激作用的低分子量或高分子量的聚硅氧烷。
[0056] 再次, 本发明的护肤组合物由于采用五种不同结构的聚硅氧烷作为主要原料组 份, 并且优选这五种聚硅氧烷总组份含量高达 27%以上。 使本护肤组合物既能充 分体现大量应用于现代医学的新型高分子材料一聚硅氧烷所具有的耐寒、 耐 热、 低表面张力、 润滑、 防潮、 疏水、 不油腻等一系列共同优良特性, 又能发 挥五种不同结构的聚硅氧烷各自的特点; 特别是占高比例含量的线型和网状型 聚甲基苯基硅氧烷具有优异的成膜性, 相容性 (配偶性) , 耐紫外能力和很强 的渗透能力, 使作为本护肤组合物基质的聚硅氧烷对皮肤渗透力、 成膜透气能 力、 自清洁、 自愈合、 自修复能力大大增强; 能很快在皮肤表面形成一层能耐 紫外光 dfl 照、 防水、 减少细菌病毒等微生物与粉尘粘附的能促进皮肤自由呼吸 的透氧薄膜, 能高效阻挡外界环境侵害, 能显著改善肤质, 手感爽滑不粘腻等 特征; 本发明的高含量的聚硅氧烷护肤组合物 (五种聚硅氧烷总组份含量高达 2 7%以上) 对下列常见皮肤病有特定疗效: 防冻, 防裂 (皲裂和皱裂) 有效率可 高达 98%, 且见效快 (一般三天) , 能防止复发; 能防治湿疹, 对夏季多汗日晒 , 冬季皮肤干裂皮屑脱落混合汗液皮脂造成的脏物皮表堆积以及粘附衣物, 高 温潮湿以及冷温阴湿等因素诱发的皮炎 -真菌感染等以及急性慢性湿疹, 均十分 有效; 能防治婴儿、 儿童的尿布湿疹 (俗称红屁股) 与老年人或长期卧床病人 的褥疮; 能软化伤口, 有辅助去疤痕的效能; 能有效防治强紫外光照的灼伤 ( 高原、 戈壁沙漠、 北方雪原、 南方丛林海滩、 航海航空等环境) ; 能有效防治 与舒缓以上五点原因诱发的皮肤损伤伴随的皮肤瘙痒, 止痒效果明显; 作为极 地考察与航天队员的护肤品, 能有效地抵御了严寒冰冻和强烈射线 (紫外线) 晒照。
[0057] 最后, 本发明的护肤组合物采用: (1) 与其他原料配位性 (相容性) 、 乳化 性能十分理想的聚甲基苯基硅氧烷为主要原料组份; (2) 由吐温 (60) 、 聚醚 改性聚硅氧烷、 单甘酯等组合成复合型非离子乳化剂。 使得乳化系统产生适合 体系需要的 HLB值, 提高界面膜 (两相间) 结合力, 增加乳化系统的稳定性, 改善产品的稠度与外观, 从而创新解决了传统护肤品的聚硅氧烷含量接近 15%吋 乳化体系"难以制取、 难以稳定"的技术难题, 成功制得了能经受冷热循环考核、 乳化性能十分稳定、 颗粒分布均匀细腻的高聚硅氧烷含量 (高达 27%) 的护肤组 合物。
[0058] 特别需要强调的是, 本发明人经深入研究发现, 上述五种聚硅氧烷由于具有良 好的相容性, 因此能够按照本发明的配方量进行作为生理活性成分的有效交联 承载结构合理配置, 使得聚硅氧烷含量能够达到 27%以上, 从而为本发明的护肤 组合物的优良性能特别是对生理活性成分的包容承载能力, 奠定良好的基础, 因为护肤组合物中基质的含量及其种类对其性能有决定性影响。 这种高聚硅氧 烷含量是传统的护肤品中从未曾实现的。
[0059] 以上介绍了本发明的护肤组合物的关键组分及其含量, 以及带来的优异的性能 。 作为护肤组合物, 考虑到多种用途和性能需求, 还可以添加其他组分。
[0060] 因此, 作为本发明的护肤组合物的进一步改进的技术方案, 还可以包含尿囊素 和透明质酸钠。
