EU regulations require full ingredient listing but not specific amounts. However, ingredients listed after preservatives (typically 0.5-1%) are present below 1% concentration. For proprietary actives, request concentration confirmation from your OEM partner.<\/p>\n<h3>What does it mean when ingredients are listed in a &#8220;proprietary blend&#8221;?<\/h3>\n<p>Proprietary blends allow suppliers to combine multiple ingredients under one trade name without disclosing individual concentrations. This is legal and common for complex peptide complexes, botanical blends, and proprietary delivery systems. You can request detailed breakdowns under confidentiality agreements.<\/p>\n<h3>How do I verify INCI accuracy for OEM products?<\/h3>\n<p>Request Certificate of Analysis (COA) for all active ingredients, third-party testing verification, and full ingredient disclosure documentation. Weitai provides complete transparency including COA, stability data, and regulatory documentation packages for all products.<\/p>\n<h3>Are &#8220;natural&#8221; or &#8220;organic&#8221; INCI names different?<\/h3>\n<p>INCI naming conventions are the same regardless of product positioning. &#8220;Natural&#8221; or &#8220;organic&#8221; claims are based on ingredient sourcing and certification, not INCI syntax. Cosmos\/Ecocert certified ingredients use standard INCI names with appropriate documentation.<\/p>\n<h2>Conclusion<\/h2>\n<p>INCI literacy is essential for B2B brand owners navigating the OEM skincare market. Understanding ingredient names, quality indicators, and regulatory requirements enables informed supplier selection and product quality evaluation.<\/p>\n<p><strong>Contact Weitai Biotechnology for OEM samples and formulation support<\/strong><\/p>","protected":false},"excerpt":{"rendered":"<p>Understanding INCI: The International Language of Cosmetics INCI (International Nomenclature of Cosmetic Ingredients) is the standardized naming system for cosmetic<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"om_disable_all_campaigns":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-23767","post","type-post","status-publish","format-standard","hentry","category-blog"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO Pro 4.9.0 - aioseo.com -->\n\t<meta name=\"description\" content=\"Understanding INCI: The International Language of Cosmetics INCI (International Nomenclature of Cosmetic Ingredients) is the standardized naming system for cosmetic ingredients used globally.
