查耳酮衍生物改性的W/Si型乳化剂的制备与性能

Preparation and properties of W/Si emulsifiers modified by Chalcone derivatives

摘要:

将查耳酮衍生物(E)-3-(4-烯丙氧基)苯基-1-(4-甲氧基苯基)丙-2-烯-1-酮(Methoxy-Cha)与烯丙基聚醚APEG-400共同接枝到含氢硅油链上,制得了具有紫外吸收性能的W/Si型乳化剂(EMCD),采用NMR确定产物的化学结构。EMCD能稳定硅油包水乳液,硅油水比在25:75~17.5:82.5范围内,EMCD质量分数为2%左右,所制备的乳液稳定性最佳。EMCD与滤光剂MBBT复配后最高总增效率达5.24%。与KF-6017相比,EMCD能使防晒乳液的体外SPF值从21.76提升至33.29,UVA/UVB比值均值从0.433提升至0.587,增强了防晒乳液的广谱防护能力。

Abstract:

W/Si emulsifier (EMCD) with UV absorption was prepared by grafting Chalcone derivative (E)-3-(4-allyloxygen)phenyl-1-(4-methoxy-phenyl)propyl-2-alkene-1-ketone (Methoxy-Cha) and allyl polyether APEG-400 onto hydrogen-containing silicone oil chains. The chemical structure of the product was determined by NMR. EMCD can stabilize the emulsion with the best stability when the ratio of silicon to water ranges from 25:75 to 17.5:82.5, and the mass fraction of EMCD is about 2%. The maximum total efficiency was 5.237% when EMCD was combined with MBBT. Compared with KF-6017, EMCD can increase the SPF value of sunscreen lotion from 21.76 to 33.29, and the average UVA/UVB ratio from 0.433 to 0.587, enhancing the broad spectrum protection capability of sunscreen lotion.
