A Practical Guide to 21 CFR 177.2600"},"content":{"rendered":"<h1 class=\"wp-block-heading\">What Is FDA Silicone?<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cFDA\u201d often appears beside hardness, viscosity and cure time in a silicone RFQ. But FDA status is not a physical property and cannot be confirmed from a TDS or platinum-cure label.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This guide explains what FDA silicone means, what 21 CFR 177.2600 requires and how to evaluate supporting documents before approving a food-mold material.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Quick answer:<\/strong> FDA silicone is not a separate polymer or blanket certificate issued by the U.S. Food and Drug Administration. For repeated-use food-contact rubber, it usually means a defined silicone formulation supported under an applicable U.S. basis\u2014commonly 21 CFR 177.2600. Compliance depends on the formulation, cured condition, intended use and evidence.<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Regulatory note: This article provides general information, not legal advice. Final requirements should be confirmed for the finished article, target market and intended conditions of use.<\/em><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is FDA Silicone Made Of?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">FDA silicone usually combines a silicone base polymer with reinforcing silica, crosslinkers and, depending on the cure system, catalysts, inhibitors or vulcanizing agents. Pigments and other processing ingredients may also be present.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What makes it different from a general-purpose industrial silicone is not its appearance. It is whether the complete formulation and cured material are supported for the intended food-contact use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Two translucent silicones can have the same hardness and appearance while only one has appropriate formulation and extractables evidence. Softness, colour and odour are not substitutes for documentation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a broader explanation of food-contact requirements across different markets, read <a href=\"https:\/\/topsilsilicone.com\/ko\/what-does-food-grade-silicone-really-mean\/\">What Does Food-Grade Silicone Really Mean?<\/a>.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"http:\/\/topsilsilicone.com\/wp-content\/uploads\/fda-silicone-complete-formulation-1024x572.jpg\" alt=\"Two-part RTV-2 silicone formulation with cured silicone, reinforcing silica and pigments\" class=\"wp-image-8899 lazyload\"\/><noscript><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"572\" src=\"http:\/\/topsilsilicone.com\/wp-content\/uploads\/fda-silicone-complete-formulation-1024x572.jpg\" alt=\"Two-part RTV-2 silicone formulation with cured silicone, reinforcing silica and pigments\" class=\"wp-image-8899 lazyload\" srcset=\"https:\/\/topsilsilicone.com\/wp-content\/uploads\/fda-silicone-complete-formulation-1024x572.jpg 1024w, https:\/\/topsilsilicone.com\/wp-content\/uploads\/fda-silicone-complete-formulation-300x167.jpg 300w, https:\/\/topsilsilicone.com\/wp-content\/uploads\/fda-silicone-complete-formulation-768x429.jpg 768w, https:\/\/topsilsilicone.com\/wp-content\/uploads\/fda-silicone-complete-formulation-18x10.jpg 18w, https:\/\/topsilsilicone.com\/wp-content\/uploads\/fda-silicone-complete-formulation-600x335.jpg 600w, https:\/\/topsilsilicone.com\/wp-content\/uploads\/fda-silicone-complete-formulation.jpg 1376w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/noscript><figcaption class=\"wp-element-caption\">A food-contact assessment must consider the complete silicone formulation\u2014not only the base polymer<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Why Is Silicone Used for Food-Contact Molds?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Silicone is considered for reusable food molds because it can combine:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>flexibility for demolding detailed shapes;<\/li>\n\n\n\n<li>stability across a wide temperature range;<\/li>\n\n\n\n<li>low water absorption and fine-detail reproduction;<\/li>\n\n\n\n<li>repeated-use durability when the grade and mold design are appropriate.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These are potential advantages, not universal specifications. Temperature resistance, tear strength, shrinkage and mold life vary by grade. Compliance also does not guarantee the correct working time, viscosity or strength for a particular mold.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Material safety and production performance must therefore be evaluated together.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Does the FDA Approve or Certify Silicone?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cFDA-approved silicone\u201d is a common commercial phrase, but it can create the wrong impression that the FDA issues a universal approval certificate for every commercial silicone grade.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">U.S. food-contact substances may be supported through a regulation, effective Food Contact Notification (FCN), Threshold of Regulation exemption or another valid basis. Authorization is connected to substance identity, intended use and conditions of use; an FCN is also manufacturer- or supplier-specific. See the FDA\u2019s overview of <a href=\"https:\/\/www.fda.gov\/food\/food-packaging-other-substances-come-contact-food-information-consumers\/understanding-how-fda-regulates-substances-come-contact-food\" target=\"_blank\" rel=\"noopener\">how food-contact substances are regulated<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For silicone evaluated under 21 CFR 177.2600, more precise wording includes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\u201cFDA-compliant silicone\u201d;<\/li>\n\n\n\n<li>\u201ccomplies with 21 CFR 177.2600\u201d; or<\/li>\n\n\n\n<li>\u201ctested to the applicable requirements of 21 CFR 177.2600.\u201d<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Buyers should still ask which grade, colour, cured condition and use the declaration or report covers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Does FDA 21 CFR 177.2600 Cover?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.ecfr.gov\/current\/title-21\/chapter-I\/subchapter-B\/part-177\/subpart-C\/section-177.2600\" target=\"_blank\" rel=\"noopener\">21 CFR 177.2600<\/a> addresses rubber articles intended for repeated use in manufacturing, processing, preparing, packaging, transporting or holding food.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It includes silicone basic polymer and several silicone elastomer categories, but the word \u201csilicone\u201d alone does not establish compliance.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Formulation Eligibility<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The complete formulation\u2014not only the base polymer\u2014must be considered. Curing materials, fillers, plasticizers, colourants and processing ingredients need an appropriate basis and must observe relevant limitations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Substances should not exceed the amount reasonably required for their technical effect or be intended to affect food.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Evidence for natural-colour silicone should not automatically cover every custom colour.

Finished-Surface Extractables<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For repeated contact with aqueous and fatty foods, the finished food-contact surface must meet the following total extractables limits under the specified conditions:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Intended contact<\/th><th>Extraction condition<\/th><th>Total extractables limit<\/th><\/tr><\/thead><tbody><tr><td>Aqueous food<\/td><td>Distilled water at reflux temperature<\/td><td>First 7 hours: \u226420 mg\/in\u00b2; succeeding 2 hours: \u22641 mg\/in\u00b2<\/td><\/tr><tr><td>Fatty food<\/td><td>n-Hexane at reflux temperature<\/td><td>First 7 hours: \u2264175 mg\/in\u00b2; succeeding 2 hours: \u22644 mg\/in\u00b2<\/td><\/tr><tr><td>Dry food<\/td><td>Formulated and cured under good manufacturing practice for repeated use<\/td><td>No corresponding numerical extraction limit stated in paragraph (d)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">These are test-specific total extractables limits, not universal migration limits.
