Aluminum Iron Calcium Magnesium Zirconium Silicates are a group of inorganic compounds often used as mineral-based ingredients in cosmetics and personal care products. They are known for their ability to absorb moisture, enhance texture, and provide a matte finish to formulations.

Chemical Composition and Structure

The chemical composition of Aluminum Iron Calcium Magnesium Zirconium Silicates includes:

• Aluminum (Al): A metal that contributes to the structure and stability of the silicate compound.
• Iron (Fe): An element that may be present to enhance color and provide additional properties.
• Calcium (Ca): A metal that helps stabilize the silicate matrix and contributes to its mineral properties.
• Magnesium (Mg): An element that further enhances the structural integrity of the silicate compound.
• Zirconium (Zr): A metal that improves the performance and stability of the silicate formulation.
• Silicates: The silicate framework provides the structural basis, contributing to the compound's properties and functions.

Structurally, these compounds consist of a silicate lattice that incorporates aluminum, iron, calcium, magnesium, and zirconium ions, resulting in a stable mineral complex with various applications in cosmetic formulations.

Physical Properties

• Appearance: Typically a fine, white to off-white powder.
• Solubility: Insoluble in water but can disperse in aqueous formulations.
• pH: Generally neutral to slightly alkaline, depending on the specific formulation.
• Melting Point: High melting point, which contributes to stability in various applications.
• Stability: Chemically stable under normal storage conditions and resistant to degradation.

Production Process

• Synthesis: These silicates are usually derived from naturally occurring minerals through a process of purification and refinement.
• Modification: The raw materials may undergo various treatments to enhance their properties, such as increasing absorbency or improving texture.
• Formulation: The final product is formulated into cosmetic products, where it is combined with other ingredients to achieve desired characteristics like texture and performance.

Applications

• Medical: Limited use in medical applications, primarily as absorbents or stabilizers in specific formulations.
• Cosmetics: Commonly used in powders, foundations, and other makeup products for their absorbent and texturizing properties. They help control oil and shine while providing a smooth application.

INCI Functions:

Bulking agent. It regulates the water content, dilutes other solids, can increase the volume of a product for better flow, acts as a buffer against organic acids, helps to keep the pH of the mixture within a certain level.

• Industrial Uses: Occasionally utilized in industrial applications where moisture absorption or thickening is required.

Environmental and Safety Considerations

Aluminum Iron Calcium Magnesium Zirconium Silicates are generally regarded as safe for use in cosmetics and personal care products when applied according to recommended guidelines. They are not known to cause significant irritation in most individuals. However, as with any ingredient, individuals with specific sensitivities should exercise caution. Sourcing should be responsible to ensure that the silicates are free from harmful contaminants and produced with minimal environmental impact.
