Consumer trust begins with safety, and this food-grade silicone colorant is formulated to meet the strictest global regulations for food-contact articles. It is designed specifically for coloring silicone bakeware, baby bottle nipples, pacifiers, reusable food storage bags, and ice cube trays, where any migrating substance is unacceptable. Each batch is tested to FDA 21 CFR 177.2600, EU 1935/2004, and LFGB standards, with full traceability documentation provided.
The colorant uses only high-purity pigments and a platinum-compatible, non-toxic silicone carrier. It is free from heavy metals, phthalates, BPA, and any substance listed on REACH or Proposition 65 restricted lists. When used as directed, the cured silicone remains completely inert and does not impart taste, odor, or color to food, even under high-temperature baking conditions up to 230°C.
This formulation has been optimized for addition-cure (platinum) liquid silicone rubber systems, including those used in injection molding and compression molding of kitchenware. It disperses rapidly without agglomerates and does not interfere with the hydrosilylation reaction, so cure speed and final physical properties are unaffected. The recommended addition is 1–4% by weight, and the colorant is compatible with transparent, translucent, and heavily filled silicone bases alike.
Because it is a liquid with a moderate viscosity, it can be metered precisely by dosing pumps into continuous mixing equipment, ensuring consistent color from shot to shot in high-volume manufacturing. The cured color withstands repeated dishwasher cycles, microwave radiation, and freezer storage without fading. Brands seeking to differentiate their silicone kitchenware with custom colors—pastel shades for baby lines, vibrant hues for gourmet bakeware—can work with our color-matching service to create exclusive, food-safe signatures. With this food-grade silicone colorant, your products gain the visual appeal they need while maintaining the absolute safety your customers expect.
