General Description:
Magnesium Carbonate is a white solid mineral that occurs naturally as a mineral known as magnesite. It is typically used in various industrial applications and can be synthesized for specific uses, including in cosmetics.
Uses in the Cosmetic Industry:
In the cosmetic industry, Magnesium Carbonate serves several potential purposes in formulations, including:
- Absorbent: Magnesium Carbonate may be used as an absorbent in cosmetics, similar to other absorbent powders like talc or kaolin clay. It helps to absorb excess moisture and oils from the skin, making it suitable for use in powders and dry formulations.
- Texturizer: It can contribute to the texture and consistency of cosmetic products, providing a smooth and silky feel.
- Anticaking Agent: In powdered cosmetics, Magnesium Carbonate may act as an anticaking agent, preventing clumping and ensuring even distribution of the product.
- Opacifying Agent: It may be used as an opacifying agent in cosmetics to provide opacity and enhance the appearance of creams, lotions, and other formulations.
Hazard:
While Magnesium Carbonate is generally considered safe for use in cosmetics, there are some potential hazards and considerations:
- Respiratory Irritation: Inhalation of fine particles of Magnesium Carbonate powder can potentially irritate the respiratory tract. Proper handling and precautions should be taken during manufacturing to minimize airborne exposure.
- Skin Sensitivity: Some individuals may experience skin irritation or allergic reactions to Magnesium Carbonate, especially if they have sensitive skin. Patch testing is recommended, especially for new products or formulations.
- Quality Control: The purity and source of Magnesium Carbonate can vary, affecting its effectiveness and safety. Cosmetic manufacturers should ensure they source high-quality, pharmaceutical-grade Magnesium Carbonate for their formulations.
CAS Number: 39409-82-0
INCI: Magnesium Carbonate
Composition: Light Magnesium Carbonate is composed of magnesium, carbon, and oxygen atoms, with the chemical formula MgCO3. It may also contain hydroxide ions, depending on the method of production and hydration level.
Purity Grade: No purity grade applicable
Appearance: Light Magnesium Carbonate typically appears as a fine white powder with a soft texture.
Solubility: Light Magnesium Carbonate is sparingly soluble in water and insoluble in alcohol. However, it can dissolve in acidic solutions due to the formation of soluble magnesium salts.
Preservation: Light Magnesium Carbonate should be stored in a tightly sealed container in a cool, dry place away from moisture and heat sources. It should also be protected from exposure to acids, which can cause decomposition.
Storage: Store in a closed container at a dry place at room temperature
Raw Material Source: Magnesium carbonate is typically sourced from natural mineral deposits, such as magnesite or dolomite. It can also be synthesized through chemical reactions between magnesium salts and carbonate sources.
Manufacture: Light Magnesium Carbonate can be manufactured through various methods, including precipitation reactions between magnesium salts (such as magnesium sulfate or magnesium chloride) and sodium carbonate or sodium bicarbonate. The resulting precipitate is then washed, dried, and milled to produce the final product.
Animal Testing: Not animal tested
GMO: GMO-free (does not contain plant-derived components)
Vegan: Does not contain animal-derived components
Proposition: LIGHT MAGNESIUM CARBONATE complies with relevant regulations and guidelines
Warning: Avoid contact with eyes. In case of contact, rinse thoroughly with water. Use appropriate protective equipment when handling. Keep out of reach of children.
THE STORY OF LIGHT MAGNESIUM CARBONATE
Light Magnesium Carbonate: The Ultra-Fine Absorbent Mineral for Dry, Smooth & Balanced Formulations
Light Magnesium Carbonate is a highly porous, lightweight mineral powder known for its excellent oil absorption, mattifying, and moisture-controlling properties.
It provides a smooth, silky touch and is widely used in face powders, dusting powders, deodorants, dry shampoos, pharma products, and sports/fitness formulations.
Refined Mineral Compound Produced Through Carbonation & Purification Processes
Light Magnesium Carbonate is created by treating magnesium salts (such as magnesium sulfate or chloride) with alkali carbonates, followed by:
• Filtration
• Drying
• Micronization
• Purification
This results in a soft, highly absorbent, ultra-light powder with exceptional surface area and cosmetic elegance.
TRCkem supplies pharma- and cosmetic-grade Light Magnesium Carbonate suitable for powders, deodorants, and skincare systems.
Absorb. Mattify. Smooth
