Iron
What is Iron?
Iron is a silvery-white transition metal element (symbol Fe, atomic number 26) utilized in cosmetics as micronized powder derived from electrolytic processes for purity. Commonly featured in powder-based makeup like foundations, blushes, and bronzers, it acts as an anticaking agent by absorbing trace moisture from the air, which inhibits particle clumping and maintains product flowability for consistent texture and effortless blending on skin. In hair care items such as dry shampoos and styling powders, it supports conditioning through surface modification that minimizes friction between strands, promoting smoother comb-through and reduced static buildup. This multifunctional role stems from its physical properties rather than chemical reactivity, making it ideal for anhydrous formulations where stability is key.
