丝肽

产品定义：
丝肽指蚕丝丝素蛋白质经降解形成水溶性的多肽物质。分子量一般在500－10000之间，水溶性好，白色粉末，茚三酮反应呈阳性。PH值4.5－6.5。
应用特性：
 
1、具有天然保湿、营养肌肤和促进皮肤伤口愈合作用
用富含丝肽的护肤品经常涂抹皮肤可达到美容及防止多种皮肤疾病的效果。经临床证明：对皮肤皱裂、皮炎、瘙痒、消除黄褐斑具有良好的疗效。实验结果表明，丝肽无刺激性，并可加快伤口愈合。丝肽还可防止粉尘、涂料、酸、碱化学物质对皮肤的侵蚀和伤害。
2、极为优异的护发功能
丝肽的护发功能主要体现在对头发的吸收性和吸附性、成膜性、调湿保湿性。
The protection for hair includes absorbability and adsorption, membrane, moisture retention.
 
（1）吸收性和吸附性：
丝肽与其它水解蛋白(胶原蛋白、骨胶蛋白、明胶蛋白等)相比，最大特点就是营养丰富易被头发所吸收。丝肽对于皮肤和毛发的吸收主要依靠渗透作用，具有直接性。丝肽浓度提高，则头发对丝肽的吸收量也相应增加。若是受损伤的头发，对低分子量丝肽的吸收和吸附量更大，相应地丝肽对头发的修复和保护作用越明显。
Compared to other protein hydrolysate peptide (protein collagen, bone glue protein, gelatin proteins, etc), silk peptide is nutrient-rich but can be easily absorbed by hair. Skin and hair absorb silk peptide directly and mainly by infiltration. When silk peptide concentration increases, the hair’s absorption for silk peptide will increase corresponding. For injury hair with greater adsorption capacity for the low molecular weight silk peptides, the corresponding effects for silk peptide on hair restoration and protection will be more obvious.
（2）成膜性：
分子量在500-2000的丝肽，其在头发上的成膜性极好，且膜具特有的光泽，头发手感好，有弹性。X射线衍射法表明：丝肽所形成的膜为β型结晶，丝肽在头发上形成的膜，可增加头发弹性和光泽。同时也可用作头发定型剂，将PVP、胶原肽、淀粉类水溶液与丝肽作对比，在80%RH的潮湿条件下，用丝肽作定型剂，可使头发长期保持良好的发型。
The silk peptide whose molecular weight ranges between 500 and 2,000, is better at making membrane, the membrane has nice luster, feels well and spring. The method of X-radial experiment showed that the membrane made from silk peptide is β-model crystal, so that the membrane covered on the hair can be hardly washed out. This is the theory of the method how the silk peptide can protect the hair. The membrane not only avoid the damnification by the chemical material, but also can enhance the spring and glare of the hair. The membrane can finalize the shape. Compared to PVP, glue peptide and amylum under 80%RH, the silk peptide is the best in keeping the hairstyle.
 
（3）调湿保湿性：
头发失去一定的水分就会干燥、开叉、容易折断、脱落。丝肽在头发表面形成的膜能防止水份过多蒸发，作为天然调湿因子，还能调节头发表面小空间的湿润度，使头发柔软、光滑。
The hair will be dry,spliting,easy to break and drop if losing some moisture.There are many hydrophilic genes, such as -OH, -COOH, -NH2, >NH, on the surface of the solid construct of its molecule. This structure shows that the silk peptide can allocate wet gene equally, and has good action of keeping hair moist and smooth.
