The widespread utilization of nail gels in the cosmetic and beauty industry, with an anticipated market value of US $65.8 Million by 2026, has raised concerns about health risks associated with conventional compositions containing monomeric acrylate reactive diluents. Technical challenges, such as oxygen inhibition leading to incomplete cure and hence tackiness after curing, further complicate their application process. This study investigates UV-LED nail gels utilizing an innovative organic-inorganic hybrid (OIH) binder system, as the utilization of OIH coatings in nail gels has been scarcely, if at all, reported, with a substantial bio-based content (>50%) without the use of any acrylate oligomer/monomers. By eliminating hazardous monomeric acrylates and addressing challenges related to free radical polymerization, the formulated nail gels achieve a 100% solid composition, free from VOC and HAPs, and possess significant bio-renewable content, ensuring safety, sustainability, and compliance with essential requirements.
美甲凝胶在化妆品和美容行业的广泛应用，预计到2026年市场价值将达到6580万美元，这引发了人们对含有单体丙烯酸酯活性稀释剂的传统配方所带来的健康风险的担忧。诸如氧气抑制导致固化不完全从而固化后发粘等技术挑战，进一步使它们的应用过程变得复杂。本研究调查了使用创新型有机-无机杂化（OIH）粘合剂体系的紫外光发光二极管美甲凝胶，因为在美甲凝胶中使用OIH涂层的情况即使有报道也极为罕见，该体系具有大量生物基成分（>50%）且不使用任何丙烯酸酯低聚物/单体。通过消除有害的单体丙烯酸酯并解决与自由基聚合相关的挑战，所配制的美甲凝胶实现了100%的固体成分，不含挥发性有机化合物和有害空气污染物，并且具有显著的生物可再生成分，确保了安全性、可持续性并符合基本要求。
