Personal care compositions comprising a polymer-bound UV absorber are described that provide enhanced properties, including customizable UV spectrum protection, broad-spectrum UV spectrum protection, water resistance, and labile UV stabilization. The polymer comprises anhydride functionality, such as maleic anhydride or a derivative thereof, and the UV absorber contains at least one hydroxyl, primary amine, or secondary amine group.
The personal care compositions may be used to treat and/or protect against burns, cancers, erythema, lentigo (“liver spots”), keratotic lesions, wrinkles, and cellular changes of the skin; and/or color changes, embrittlement, lack of luster, tangles, split ends, and/or unmanageability of the hair.
本文描述了含有聚合物结合的紫外线吸收剂的个人护理组合物,提供了增强的性能,包括可定制的紫外线光谱保护,广谱紫外线光谱保护,耐水性和不稳定的紫外线稳定性。聚合物包含酐官能团,例如马来酸酐或其衍生物,而紫外线吸收剂含有至少一个羟基,一级胺或二级胺基团。这些个人护理组合物可用于治疗和/或预防烧伤、癌症、红斑、黑色素瘤(“肝斑”)、角化病变、皱纹和皮肤细胞变化;以及头发的颜色变化、变脆、缺乏光泽、打结、分叉和/或难以管理。
