General Description:

Sodium Meta Silicate Anhydrous is a chemical compound with the formula Na2SiO3. It is a white, crystalline solid that is soluble in water and alkaline in nature. Anhydrous forms of sodium metasilicate do not contain water molecules in their crystal structure.

Uses in the Cosmetic Industry:

  • Sodium Meta Silicate Anhydrous serves several purposes in cosmetics, including:
  • Cleansing Agent: It is used in cleansers, soaps, and detergents for its ability to break down oils and dirt, helping to cleanse the skin and hair effectively.
  • Emulsifier: Sodium metasilicate can act as an emulsifying agent, helping to stabilize oil-in-water emulsions in cosmetic formulations such as creams and lotions.
  • Buffering Agent: It helps to maintain the pH of cosmetic products, ensuring that they remain stable and compatible with the skin.
  • Chelating Agent: Sodium metasilicate can chelate metal ions in water, reducing the effects of hard water in cleansing products.

Hazard:

While sodium metasilicate anhydrous is generally regarded as safe for use in cosmetics, there are some considerations:

  • Skin Irritation: In high concentrations, sodium metasilicate can potentially cause skin irritation, especially in individuals with sensitive skin. Proper formulation and usage levels are important to minimize the risk of irritation.
  • Eye Irritation: Direct contact with sodium metasilicate powder or solutions can irritate the eyes. Safety precautions should be taken during handling to avoid eye exposure.
  • Respiratory Sensitization: Inhalation of sodium metasilicate dust can irritate the respiratory tract. Proper ventilation and handling procedures should be followed to minimize exposure.
  • Environmental Impact: Sodium metasilicate is biodegradable, but large amounts released into water bodies can affect pH levels and aquatic life. Proper disposal practices should be followed.
  • Regulatory Compliance: Cosmetic-grade sodium metasilicate anhydrous must comply with regulatory standards set by authorities such as the FDA in the United States and the European Commission. Maximum allowable concentrations and usage conditions are specified to ensure consumer safety.

CAS Number: 6834-92-0

INCI: Sodium Metasilicate

Composition: Sodium metasilicate anhydrous is composed of sodium ions (Na+) and metasilicate ions (SiO3^2-).

Purity Grade: No purity grade applicable

Appearance: Sodium metasilicate anhydrous appears as a white, granular or powdered substance.

Solubility: Sodium metasilicate anhydrous is highly soluble in water, forming an alkaline solution. It is sparingly soluble in organic solvents.

Preservation: Sodium metasilicate anhydrous is typically stable under normal storage conditions when kept in a dry environment and protected from moisture. It should be stored in tightly closed containers to prevent absorption of water vapor from the atmosphere.

Storage: Store in a closed container at a dry place at room temperature

Raw Material Source : The raw materials for sodium metasilicate production include sodium carbonate and silicon dioxide (silica sand).

Manufacture: Sodium metasilicate anhydrous is produced by fusing sodium carbonate with silica sand (silicon dioxide) at high temperatures. The resulting molten mass is then quenched with water to form an amorphous solid, which is further processed into the crystalline form of sodium metasilicate anhydrous.

Animal Testing: Not animal tested

GMO: GMO-free (does not contain plant-derived components)

Vegan: Does not contain animal-derived components

Proposition: SODIUM META SILICATE ANHYDROUS 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.

Collapsible content

Sodium Metasilicate Anhydrous is an inorganic compound widely used in personal care and cosmetic formulations for its alkalinity, cleansing, and stabilizing properties. It serves as a pH adjuster, buffering agent, and cleansing aid, helping enhance the performance of products such as cleansers, scrubs, and exfoliating formulations. Its anhydrous form ensures high purity, stability, and ease of formulation handling.

CAS Number: 6834-92-0
INCI Name: Sodium Metasilicate

pH Regulation: Maintains the desired alkalinity in cleansing and exfoliating formulations.
Stabilization: Helps stabilize emulsions and other formulation systems.
Cleansing & Exfoliation: Enhances removal of impurities, dead skin, and buildup.
Enhanced Performance: Boosts the effectiveness of surfactants and cleaning agents.
Preservative Synergy: Exhibits mild antimicrobial properties that can support product preservation.

Yes, Sodium Metasilicate Anhydrous is considered safe when used in low, regulated concentrations. It must be carefully formulated to maintain skin compatibility. It is recommended only for rinse-off or controlled-use formulations to avoid potential irritation from high alkalinity.
