考察了4种紫外线吸收剂DHHB、OS、OMC、MCE进行复配,对5种化妆品中常见的着色剂进行光稳定性研究.经过28天的光稳定性试验,以色素保存率进行分析,研究结果表明,0.1%的紫外线吸收剂复配物即可对着色剂产生一定的保护作用,而0.5%的复配物能显著改善着色剂的光稳定性.在日化产品中添加紫外线吸收剂能够明显改善着色剂因紫外线引起的褪色、变色或者光降解变质等问题.
Study on the photostability of four preferred UV absorber compounds on colorants
Color plays an important role in the daily chemical product market.The transparent packaging of daily chemical products are loved by consumers,but it is difficult to avoid the inner material of the product from fading,discoloration or photodegradation.UV light is a major contributor to colorant fading,which can affect color stability by damaging chromogenic groups and producing free radicals.In view of this,the combination of four ultraviolet absorbers DHHB,OS,OMC,and MCE was investigated,and the photostability of five common colorants in cosmetics was studied.After 28 days of photostability test,the pigment preservation rate was analyzed,and the results showed that 0.1%of the UV absorber compound could have a certain protective effect on the colorant,and 0.5%of the compound could significantly improve the photostability of the colorant.Adding ultraviolet absorbers to daily chemical products can significantly improve the fading,discoloration or photodegradation of colorants caused by ultraviolet rays.
