Biodegradable Hyperbranched Polyesters as Scaffolds for Next-Generation Sunscreens

黑色素瘤皮肤癌是英国第五大流行癌。防晒是一个不断增长的全球市场，越来越多的消费者在日光浴时使用防晒产品，或将其作为日常生活的一部分，以防止有害的紫外线辐射。一次性使用的保护剂依赖于有机紫外线吸收剂，由于它们在皮肤内的渗透性和它们对环境的影响，它们处于立法压力之下。夏威夷已经禁止使用最具破坏性的保护剂，许多其他地区正在审查其使用情况。通过将这些UV吸收剂附着到预成型的生物来源和生物衍生的聚合物上，可以减轻这些有效试剂的负面影响。该产品将使高价值特种聚合物添加剂行业能够更好地为全球市场提供独特的产品。

Melanoma skin cancer is the 5th most prevalent carcinoma in the UK. Sun protection is a growing world market with more and more consumers utilising sun protection products both while sunbathing or as part of their daily routine against harmful UV radiation. Apply-once protection agents rely upon organic UV absorbers which are under legislative pressure due to their permeation within the skin and their environmental impact. Hawaii has outlawed the most damaging protection agents from formulations with many other territories reviewing their use. By attaching these UV absorbers to pre-formed, bio-sourced and bio-derived polymers the negative impact of these effective agents can be mitigated. This offering will allow the high value speciality polymer additive industry to build-back better with a unique offering to the world marketplace.
