IRON HYDROXIDE

Description

Iron hydroxide, also known as ferric hydroxide, is a versatile inorganic compound widely used in skincare and cosmetic formulations. This reddish-brown pigment is prized for its ability to impart warm, earthy tones to various products, including foundations, blushes, and eyeshadows. Beyond its colorant properties, iron hydroxide offers several benefits in skincare applications.

As a mineral-based ingredient, iron hydroxide is generally well-tolerated by most skin types and is considered non-toxic when used in appropriate concentrations. It functions as an effective UV filter, providing broad-spectrum protection against both UVA and UVB rays, thus contributing to sun protection in mineral-based sunscreens. Iron hydroxide also exhibits mild astringent properties, which can help tighten pores and reduce excess oil production.

In formulations, iron hydroxide is often combined with other mineral pigments to achieve desired color outcomes and coverage levels. Its stability in various pH environments makes it suitable for incorporation into a wide range of product types. However, formulators must consider potential oxidation reactions when combining iron hydroxide with certain active ingredients. Proper dispersion techniques are crucial to ensure uniform distribution and prevent clumping in final products.
