- DESCRIPTION
CAS Number : 7631-86-9
INCI: Silica
Composition: Precipitated silica primarily consists of silicon dioxide (SiO2), with small amounts of water and impurities depending on the manufacturing process.
Purity Grade: No purity grade applicable
Appearance: Precipitated silica typically appears as a fine white powder or granules.
Solubility: Precipitated silica is insoluble in water and organic solvents. It forms stable suspensions in liquids.
Preservation : Precipitated silica should be stored in a cool, dry place away from direct sunlight and moisture to prevent agglomeration and degradation. It should be kept in airtight containers to maintain its quality.
Storage: Store in a closed container at a dry place at room temperature
Country of Origin: India
Raw Material Source : The raw materials for precipitated silica include sodium silicate (derived from sand or quartz) and mineral acids such as sulfuric acid or hydrochloric acid.
Manufacture: Precipitated silica is manufactured through the reaction of sodium silicate with a mineral acid such as sulfuric acid or hydrochloric acid, resulting in the precipitation of silica particles. The precipitated silica is then filtered, washed, and dried to obtain 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: PRECIPITED SILICA 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.
General Description:
Precipitated silica is a form of synthetic amorphous silica, produced by the precipitation of silica (silicon dioxide) from a solution. It is a fine, white, odorless powder with high purity and a variety of particle sizes. Precipitated silica differs from naturally occurring silica in its production method, which allows for controlled particle size and surface area.
- Uses in the Cosmetic Industry:
Precipitated silica serves several purposes in cosmetics: - Matting Agent: It is used to impart a matte finish in cosmetic products, such as foundations, powders, and blushes. Precipitated silica absorbs excess oil and reduces shine on the skin, providing a smooth, non-greasy appearance.
- Thickener: Precipitated silica acts as a thickening agent in cosmetic formulations, improving viscosity and texture. It helps stabilize emulsions and suspensions, enhancing the overall stability and consistency of products.
- Abrasive: In toothpaste and exfoliating products, precipitated silica serves as an abrasive agent that gently removes plaque and dead skin cells without causing irritation.
- Anti-caking Agent: It prevents clumping and improves flow properties in powdered cosmetics, ensuring uniform distribution and ease of application.
- Absorbent: Precipitated silica absorbs moisture and sweat, making it useful in antiperspirants and deodorants to enhance dryness and reduce odors.
Hazard:
While generally regarded as safe for use in cosmetics, there are some potential hazards and considerations associated with precipitated silica:
- Skin Irritation: Excessive or prolonged exposure to precipitated silica can cause skin irritation, especially in individuals with sensitive skin. It is advisable to use products containing precipitated silica as directed and to perform a patch test if you have sensitive skin.
- Respiratory Hazard: Inhalation of fine silica dust can irritate the respiratory tract and lungs. Workers handling powdered forms of precipitated silica should use appropriate respiratory protection to minimize exposure.
- Eye Irritation: Direct contact with precipitated silica powder can irritate the eyes. Safety precautions should be taken during handling to avoid eye exposure.
- Environmental Impact: Like other fine particles, precipitated silica can pose environmental risks if not properly managed during disposal. Efforts should be made to minimize its release into the environment.
- Regulatory Compliance: Cosmetic-grade precipitated silica must comply with regulatory standards set by authorities such as the FDA in the United States and the European Commission. Maximum allowable concentrations and purity levels are specified to ensure consumer safety.
