Product Description

Magnesium silicate is a white or off-white fine free-flowing powder with CAS number 1343-88-0. It is a versatile inorganic additive commonly applied in food, cosmetics and related industries. It mainly functions as an anticaking agent and adsorbent, which can absorb excess moisture, oil and impurities efficiently. It helps powdered products stay loose and prevents particles from clumping together during storage and transportation. This product has stable chemical properties and can also be used as a carrier or filter aid in different formulations. It features low reactivity and will not alter the original flavor and texture of the end product at proper dosages. Our product is produced under strict quality control to guarantee consistent batch performance. We can provide supporting documents such as COA and SDS for inspection and customs clearance. It effectively absorbs excess moisture and oil to prevent powder caking and maintain good flowability. It acts as an adsorbent to trap unwanted impurities and support clarification in liquid systems. It can be used as an inert carrier for active ingredients in various powder formulations.

Functions and Effects

Magnesium silicate powder acts as an efficient anticaking agent for various powder formulations. It absorbs surplus moisture and oil to stop solid particles from sticking together and forming lumps. It preserves good free-flowing characteristics of powdered raw materials throughout storage and transit. It works as an adsorbent to trap undesired impurities in food and cosmetic systems. It can also serve as a carrier and filter aid to improve the stability of finished products. It helps reduce blockages during automated powder filling and packaging processes. It maintains consistent physical performance under normal temperature and humidity storage conditions. It does not easily react with most common raw materials in standard formulations. It helps extend the shelf stability of powdered end products by controlling moisture. It can assist in clarifying liquid systems by adsorbing suspended fine contaminants. It meets the dosage limits set by global food and cosmetic regulations for safe use. It delivers stable adsorption performance even in complex mixed powder formulas. It is compatible with most other common anti-caking additives.

Application Fields

Magnesium silicate powder is widely used as an anticaking agent and adsorbent in food, cosmetic and industrial fields. It is suitable for various powdered food blends, seasoning powders and dietary supplement powders to maintain flowability. It can be added to cosmetic powders such as loose powder and pressed powder to absorb excess sebum and oil. It is also adopted as a filter aid and clarifying agent in liquid processing to remove suspended impurities. It can be used as an inert carrier for active ingredients in different powder formulations. It is applicable in automated powder production lines to avoid clogging during packaging and conveying. It complies with corresponding regulatory limits for food and cosmetic raw materials in export markets. It is commonly packed in woven bags or paper drums for bulk shipment and long-term storage. It can be blended with other anti-caking additives to achieve better comprehensive performance. It needs to be dosed in accordance with local regulations for different application scenarios. It can improve the texture and spreadability of cosmetic powder products. It is available in different particle sizes to match diverse formulation requirements. It is well accepted by many international customers for its stable quality.
