Overview
Success Gadget Nanotecnologia e Novos Materiais is a Portuguese company based in Barcelos that researches, develops and commercialises advanced technological solutions for textiles and other surfaces. Its core asset is a patented nanotechnology platform called Sil2U, which the company describes as unique on the market and as its competitive advantage. The company has an embryonic link to the University of Minho and operates within a business group closely connected to the textile industry, from which it has gained operational autonomy. The company's mission is framed around protecting consumer well-being and contributing to a healthier society. Its portfolio spans anti-viral disinfectants, anti-insect treatments for textiles, washing machines, industrial applications, cosmetics, multi-surface use and paints/varnishes, as well as anti-odour solutions for textiles and sprays. It also markets a Breath technology line. Success Gadget states that it carries out research, product development and commercialisation entirely in-house, and that it operates an R&D laboratory equipped with advanced instrumentation and staffed by dedicated human resources. In 2018 the company obtained recognition of its suitability to conduct R&D activities from the Portuguese National Innovation Agency (Agência Nacional da Inovação), which makes its partners eligible for support in areas such as Cultural and Creative Industries – Fashion (technical textiles and apparel), Habitat (home textiles, paints and coatings, new/advanced materials), Health (biotechnology and health) and Production Technologies and Process Industry (industrial biotechnology). The company also claims to be the first European company with an anti-insect product containing IR3535 authorised in the ECA and compliant with the Biocidal Product Regulation, underlining that the safety and efficacy of its formula substances are proven and authorised under strict directives. Success Gadget presents itself as a biofunctional innovation player with a conscious positive market impact and effective environmental savings in its processes. Its services cover research and development, laboratory testing, clinical trials, production and distribution. Application areas and patents cover fashion and technical textiles, construction (paints and coatings), health (hospitals and biotechnology) and industrial biotechnology. The company publishes news and updates on topics such as COVID-19 prevention, tropical diseases, the link between global warming and tropical diseases, and the Global Arbovirus Initiative, positioning its technology as relevant to public-health challenges as well as to consumer textile performance.
History
Success Gadget Nanotecnologia e Novos Materiais is a Portuguese company headquartered in Barcelos. It emerged with an embryonic connection to the University of Minho and subsequently achieved autonomy within a business group that has close ties to the textile industry. This origin shaped its focus on advanced materials and surface treatments for textiles and related substrates. The company built its activity around a patented nanotechnology platform named Sil2U, which it presents as unique on the market and as the foundation of its competitive advantage. Rather than acting only as a formulator, Success Gadget describes an integrated model in which research, development of innovative products and their commercialisation are all carried out in-house. It operates an R&D laboratory equipped with advanced equipment and staffed with the human resources and investment needed to pursue its objectives. A significant institutional milestone came in 2018, when the Portuguese National Innovation Agency recognised the company's suitability to carry out R&D activities. This status gives its partners eligibility for support in several domains: Cultural and Creative Industries – Fashion (technical textiles and apparel); Habitat (home textiles, paints and coatings, new materials/advanced materials); Health (biotechnology and health); and Production Technologies and Process Industry (industrial biotechnology). Success Gadget has also positioned itself in the biocidal products space. It states that it is the first European company with an anti-insect product containing IR3535 authorised in the ECA and compliant with the Biocidal Product Regulation, emphasising that the safety and efficacy of the substances in its formulas are proven and authorised under rigorous directives. Its service offering extends from research and development through laboratory testing and clinical trials to production and distribution. In terms of applications and patents, the company lists fashion and technical textiles, construction (paints and coatings), health (hospitals and biotechnology) and industrial biotechnology. Its public communications have addressed COVID-19 prevention, tropical diseases, the relationship between global warming and tropical diseases, and the Global Arbovirus Initiative, reflecting an effort to connect its biofunctional technologies to broader public-health concerns. The company continues to market its AntiVírico SG, Anti-Inseto SG and Antiodor SG product families and its Breath technology line.
