Nanomaterials thus form a new family of chemical agents that display multiple differences in terms of composition, dimensional characteristics and physico-chemical properties. For example, gold is completely inactive at the micrometric scale, but becomes an excellent catalyst for chemical reactions when it reaches nanometric dimensions.<br\/><\/p>\n\n<h3 class=\"wp-block-heading\">Nanomaterials present in the food industry, water and cosmetic products<\/h3>\n\n<p class=\"wp-block-paragraph\">Inorganic nanoparticles are used in the food industry as additives depending on their properties: flavour enhancers, whitening agents, decoration, anti-caking agents, clarifying agents or abrasives, etc. They can also be found in cosmetic products and wastewater.<\/p>\n\n<h3 class=\"wp-block-heading\">Titanium dioxide (TiO2)<\/h3>\n\n<p class=\"wp-block-paragraph\">Listed as an additive (E171), TiO2 is used for its whitening and glossy properties in many confectionery items, pastry decorations, ice cream and biscuits. From a regulatory standpoint, it is <a href=\"https:\/\/dev.phytocontrol.com\/en\/regulatory-watch\/french-ban-on-titanium-dioxide-e171-in-foodstuffs\/\">banned in foodstuffs.<\/a> <br\/><\/p>\n\n<h3 class=\"wp-block-heading\">Gold nanoparticles<\/h3>\n\n<p class=\"wp-block-paragraph\">Gold leaf or powder (E175) is used mainly as a colouring agent, or for decorating confectionery and chocolates, as well as in liqueurs. Gold nanoparticles may be present in wastewater. <br\/> <strong>Gold nanoparticles have optical properties used in nanomedicine for anti-cancer therapy and imaging. They are also used in cosmetic formulations such as creams, make-up, powders, etc.<\/strong><\/p>\n\n<h3 class=\"wp-block-heading\">Silver nanoparticles<\/h3>\n\n<p class=\"wp-block-paragraph\">Silver nanoparticles are mainly used for their biocidal properties, through the release of Ag+ ions (known for their toxicity). They are found in certain food supplements, food packaging, non-food products (e.g. toothpaste), and textiles. Silver nanoparticles may be used as a food additive (E174), mainly for decorating confectionery and pastries. <br\/><\/p>\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.phytocontrol.com\/wp-content\/uploads\/2021\/04\/fond_de_teint.png\" alt=\"foundation makeup\"\/><\/figure>\n\n<h3 class=\"wp-block-heading\">The Phytocontrol solution<\/h3>\n\n<p class=\"wp-block-paragraph\">Phytocontrol is able to detect and quantify the particle size distribution of titanium dioxide, gold and silver nanoparticles using its latest-generation <strong>SP-ICP-MS<\/strong> technology. <br\/><br\/> The Group&#8217;s 3 areas of expertise: <strong> <a href=\"https:\/\/dev.phytocontrol.com\/en\/agrifood\/\">Agrifood <\/a><\/strong>for the <strong>food industry<\/strong>, <strong><a href=\"https:\/\/dev.phytocontrol.com\/en\/waters\/\">Waters <\/a><\/strong>for the <strong>water and environment<\/strong> sector, and <strong><a href=\"https:\/\/dev.phytocontrol.com\/en\/biopharmaen\/\">Biopharma <\/a><\/strong>for the <strong>cosmetic products<\/strong> sector, support you in managing potential risks related to nanomaterials according to your field of application. <br\/> <br\/><\/p>\n\n<p class=\"wp-block-paragraph\">Need technical, regulatory or pricing information?
