Description

一种护肤品及其制备方法
本申请要求于2015年8月28日提交中国专利局、申请号为201510540636.X、发明名称为“一种护肤品及其制备方法”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明属于美容护肤品领域,具体涉及一种护肤品及其制备方法,尤其涉及一种祛痘护肤品及其制备方法。
背景技术
痤疮,俗称痘痘,又叫青春痘、粉刺、寻常性痤疮、暗疮,是一种常见皮肤疾病,能造成人体皮肤上皮脂腺或毛囊的发炎,局部病变时会产生能挤出白色或乳白色碎米样粉汁的刺状丘疹。痘痘好发于青春期的男性和女性,男性略多于女性,但女性发病早于男性。痘痘好发于面颊、额部、颊部和鼻唇沟,其次是胸部、背部和肩部。痘痘皮损一般无自觉症状,炎症明显时可伴有疼痛,可分为粉刺、丘疹、脓疱、囊肿结节。有80-90%的青少年患过痘痘,青春期后往往能自然减退或痊愈,个别患者也可延长到30岁以上。虽然痘痘是有自愈倾向的疾病,但是痘痘本身以及痘痘治疗不及时引起的瘢痕可以严重影响患者的生活质量,造成患者的精神压力和经济负担,需引起关注。
痘痘的发生主要与皮脂分泌过多、毛囊皮脂腺导管堵塞、细菌感染和炎症反应等因素密切相关。进入青春期后人体内雄激素特别是睾酮的水平迅速升高,促进皮脂腺发育并产生大量皮脂。同时毛囊皮脂腺导管的角化异常造成导管堵塞,皮脂排出障碍,形成角质栓即微粉刺。毛囊中多种微生物尤其是痤疮丙酸杆菌大量繁殖,痤疮丙酸杆菌产生的脂酶分解皮脂生成游离脂肪酸,同时趋化炎症细胞和介质,最终诱导并加重炎症反应。
痘痘分为炎性痘痘及非炎性痘痘。皮肤油脂分泌过旺及毛孔堵塞通常会形成非炎性痘痘(即粉刺),细菌在粉刺内过度生长会引起炎症,从而形成炎性痘痘。炎性痘痘对于皮肤的损害达到真皮层会形成痘痕(痘印/痘疤)。
然而目前各种用于治疗痘痘的药物中大多含有激素、抗生素,这类药虽然能达到祛痘的效果,但是其副作用也相对较大,依赖性强,不宜长期使用。而目前市场上常用的祛痘产品则选用水杨酸、辛酰水杨酸、乙醇、果酸等成分为主要功效物质,用于杀菌消炎,避免形成炎性痘痘。但水杨酸、辛酰水杨酸、乙醇、果酸等成分刺激性较大,常常会造成皮肤敏感、刺痛、严重脱皮等副作用,且长期使用后会产生耐受性。此外市场上还存在以中草药提取物为主要成分的祛痘产品,但过于温和,起效慢、效果差。

1.2、中药组合物样品:D1、D2、D3、D4、D5、D6样品,4℃存放备用。其中D1至D6依次对应实施例1、2、3和对照例1、2、3制备 的产品。
1.3、培养基:痤疮丙酸杆菌培养基,调节pH为6.6~7.0。其中固体培养基中加入琼脂15g/L。
2、方法
2.1、菌悬液制备及接种
取冷冻保藏菌悬液0.1ml于5ml痤疮丙酸杆菌液体培养基中,于37℃厌氧条件培养2d,为实验菌悬液。
2.2、药液制备:将D1、D2、D3、D4、D5、D6分别用生理盐水稀释成试验浓度0.1%,然后分别梯度稀释。第一次试验梯度稀释浓度分别为100%(样品原液)、50%、25%、12.5%、6.25%、3.125%、1.56%、0.78%。第二次试验复测梯度稀释浓度分别为10%、8%、6%、4%、2%。
2.3、菌液制备
用痤疮丙酸杆菌液体培养基稀释菌悬液,使其最终菌浓度为l06CFU/ml。
2.4、培养及结果判读:在微孔中加入菌液100μL和药液100μL,同时设不加菌的阴性对照和不加药液的正常生长对照,每种药做3个平行,取平均值。置37℃厌氧孵育,48h后观察结果。采用肉眼判断有无浑浊,采用直接法读取数据。结果判断的前提是生长对照良好,空白对照无菌生长清晰,其它孔随药物浓度梯度升高而菌的生长受到抑制。

2.5、结果:
从表1结果可见,3组实施例0.1%的溶液,均在其稀释至12.5%浓度及以上,对痤疮丙酸杆菌有良好抑制作用,而对照例中D4在25%稀释液及以上才能达到效果,D5及D6则需要50%浓度以上。从表2结果可见,经过验证,D1、D3的抑菌浓度可在8%稀释液达到,而D2也在10%的浓度达到了抑菌效果。
由上述结果可知,最低添加本发明所述组合物成品约0.01%,即可基本达到抑制痤疮丙酸杆菌的效果,且本发明所述组合物比单味药材使用具有更强的抑菌效果。
