Description

Hydrophilic Black Oxide is a black pigment with hydrophilic (water-attracting) properties, used in cosmetic formulations to impart color and provide aesthetic benefits. It is often used in various types of products, including makeup and skincare, to enhance visual appeal and performance.

Chemical Composition and Structure

Active Compounds: Primarily composed of iron oxides.
Structure: The compound is a fine, black powder with a crystalline structure.
Hydrophilic Nature: Modified to have an affinity for water, which helps in its dispersion in aqueous formulations.

Physical Properties

Appearance: Fine, black powder.
Odor: Odorless.
Solubility: Hydrophilic, meaning it disperses well in water-based formulations.
Texture: Smooth, non-gritty powder.

Production Process

Synthesis: The black oxide is produced through the oxidation of iron compounds.
Modification: It is treated to enhance its hydrophilic properties.
Milling: The material is finely ground to achieve a powdery consistency.
Packaging: Packaged under controlled conditions to prevent contamination and degradation.

Applications

Cosmetics: Used in makeup products like foundations, eyeliners, and mascaras for its pigmentation and color stability.
Skincare: Included in formulations to provide a visual effect and improve the texture of the product.
Pharmaceuticals: May be used in certain topical applications for its colorant properties.

Environmental and Safety Considerations

Biodegradability: Generally inert and does not biodegrade but is stable in formulations.
Toxicity: Considered safe for use in cosmetics when used according to recommended guidelines. It should be used in appropriate concentrations to avoid any potential skin irritation or allergic reactions.
Disposal: Dispose of in accordance with local regulations for non-hazardous waste.

INCI Functions:
