STTR Phase II: Benign Thin Film Composite Particles for Protection from UVA/UVB - Rays

这个小企业技术转让研究（STTR）第二阶段项目提供了表面钝化的复合二氧化钛/氧化锌颗粒的商业化，用于对UVA和UVB辐射的良性保护。 复合颗粒通过新型原子层沉积（ALD）技术制造。 这些材料的目标是用于防晒护肤制剂;惰性涂层将允许颗粒容易地分散在各种制剂中，并将防止活性二氧化钛或氧化锌与皮肤之间的直接接触。 在更多种类的护肤产品中引入新的、更有效的UVA/UVB防护，可以帮助解决太阳引起的皮肤癌这一主要健康问题。该第二阶段项目将集中于改进材料设计、大规模生产，并证明这些复合材料在UVA/UVB透射率和防晒因子配方中的有效性。

This Small Business Technology Transfer Research (STTR) Phase II project provides for the commercialization of surface-passivated composite titania/zinc oxide particles for benign protection from UVA and UVB radiation. The composite particles are manufactured via novel atomic layer deposition (ALD) technology. These materials are targeted at use in sunblock skin care formulations; the inert coating will allow easy dispersion of the particles in a variety of formulations, and will prevent direct contact between active titania or zinc oxide and the skin. The major health problem of sun-induced skin cancer could be helped with the introduction of new, more effective UVA/UVB protection in a wider variety of skin care products.This Phase II project will focus on refining the material design, production at larger scale, and proving the effectiveness of these composites in formulations for UVA/UVB transmittance and sun protection factors.
