Product Description

Magnesium stearate fine white powder for coating plastic  textile as emulsifier demoulding lubricant stabilizer

Magnesium stearate appears as a fine white powder with a smooth and greasy touch, featuring unique physical and chemical properties. In terms of solubility, it is insoluble in cold water, ethanol, and ether, but dissolves in hot water and hot ethanol. When exposed to acids, it decomposes into stearic acid and the corresponding magnesium salt.

As a multifunctional material, magnesium stearate plays a key role in various industries. In the food sector, it is a common additive used to regulate texture and stability; in the  industry, it is frequently employed as a tablet lubricant to facilitate molding and demolding without affecting drug efficacy. In coatings, plastics, and rubber industries, magnesium stearate serves as an emulsifier, demolding agent, lubricant, and stabilizer, improving product processing performance and quality. In textiles, it acts as an auxiliary agent to optimize production processes. Additionally, it is an excellent stabilizer and lubricant for materials like PVC, cellulose acetate, and ABS resin. When combined with calcium and zinc soaps, it is suitable for producing non-toxic products, greatly expanding its application scenarios. With its stable performance and wide applicability, magnesium stearate has become an indispensable raw material in numerous industrial production processes.

Basic Info

Medical Industry
Function: Serves as a lubricant and release agent for tablets and capsules with stabilizing effects, reducing friction between drug particles, enhancing flowability during tableting, minimizing die wear, preventing tablets from sticking to punches to improve demolding efficiency and avoid chipping/adhesion, while acting as a thickener in ointment bases to regulate consistency and stability.
Coatings & Inks
Function: Acts as an emulsifier, lubricant and anti-sediment agent, improving pigment dispersion in coatings, preventing filler settlement, enhancing coating uniformity; reducing friction between ink and printing equipment as an ink lubricant to ensure clarity, and imparting smooth tactile feel and scratch resistance to coatings (e.g., wood/metal paints).
Plastics & Rubber Industry
Function: Works as a stabilizer, lubricant and release agent. In plastics, applied to PVC, cellulose acetate, ABS resin etc., inhibiting thermal degradation during processing, reducing melt viscosity, improving extrusion/injection flow; used in non-toxic plastic products (e.g., food packaging) when compounded with calcium/zinc soaps. In rubber, as an auxiliary to vulcanization accelerators, shortening curing time and enhancing abrasion/tear resistance of tires, seals etc.
Textile Industry
Function: Acts as a textile auxiliary for softening, lubrication and antistatic properties, added to fiber spinning oils to improve yarn smoothness and bundling, reducing breakage during weaving; serving as an emulsifier in fabric finishing agents to enhance adsorption and uniform distribution on fiber surfaces.
Cosmetics Field
Function: Used as a cosmetic base, lubricant and thickener, improving flowability and preventing caking in powder products like foundations/eyeshadows; regulating consistency in creams/lotions to impart silky texture; acting as an anti-adhesive in pressed powders to improve compaction and demolding.
