Calcium Stearate CAS 1592-23-0

INCI Name:Calcium Stearate

BLIT Chemical Calcium Stearate is White light crystalline powder, decomposed under intense heat.Insoluble in water, cold ethyl alcohol and diethyl ether, soluble in hot benzene, methylbenzene and turpentine, slightly soluble in hot ethyl alcohol and diethyl ether.It’ll decompose into stearic acid and its corresponding calcium salt when meeting strong acid.

Calcium Stearate is a calcium salt of stearic acid, known for its excellent lubricating, anti-caking, and stabilizing properties. It is widely used in various industries, including cosmetics, plastics, rubber, pharmaceuticals, and food, due to its versatility and safety profile. As a non-toxic, water-repellent powder, Calcium Stearate serves as a key additive to enhance the texture, stability, and processing of products.

Lubricant: Provides smoothness and reduces friction in various formulations, improving flow and processability.

Anti-Caking Agent: Prevents clumping in powders and granular materials, ensuring free-flowing characteristics.

Heat Stabilizer: Protects against degradation during processing in plastics and rubber applications.

Water Repellency: Offers hydrophobic properties, making it ideal for moisture-resistant applications.

Application：

Cosmetics and Personal Care: Used in face powders, foundations, creams, and lotions to improve texture, enhance spreadability, and prevent caking. It also acts as a lubricant, providing a smooth application and a soft feel on the skin.

Plastics Industry: Calcium Stearate can be used as thickener for lubricating grease, as well as water-proofing agent for waterproof fabrics.

Rubber Industry: Acts as a mold release agent and lubricant in rubber processing, aiding in the efficient release of rubber products from molds and enhancing the overall quality of the finished goods.

Pharmaceuticals: Used as a tablet lubricant and anti-adherent in pharmaceutical formulations, ensuring consistent tablet size and shape while preventing ingredients from sticking to equipment.

Food Industry: Serves as a food additive (E470a) in powdered products to prevent caking and improve texture, commonly found in spices, flavorings, and dietary supplements.

Calcium Stearate can be used as stabilizer and lubricating agent for polyvinyl chloride, as well as halogen absorbent for polyethylene and polypropylene.

Calcium Stearate can be used as thickener for lubricating grease, as well as water-proofing agent for waterproof fabrics.

Calcium Stearate can be used as flatting agent for paints as well as lubricating agent for pencil leads.

Usage Guidelines:

Cosmetic Formulations: Use Calcium Stearate at concentrations of 0.5% to 5% in face powders and other cosmetic products to improve texture, spreadability, and anti-caking properties. Incorporate it into the powder phase or blend it with other dry ingredients for uniform distribution.

Plastic Manufacturing: Add Calcium Stearate at levels of 0.1% to 1% as a heat stabilizer and lubricant in PVC and other plastic formulations. It should be thoroughly mixed with the polymer to enhance processing efficiency and prevent thermal degradation during high-temperature processing.

Rubber Processing: In rubber applications, use Calcium Stearate at 0.5% to 3% to improve mold release and flow properties. It can be mixed with other rubber ingredients to ensure consistent dispersion throughout the compound.

Pharmaceutical Applications: For tablet manufacturing, use Calcium Stearate as a lubricant and anti-adherent at 0.25% to 1%. It helps to improve the flow of powders and prevent them from sticking to the tablet press, ensuring consistent tablet quality.

Food Industry Applications: In the food industry, Calcium Stearate can be used as an anti-caking agent in powdered products at levels up to 2%. It should be uniformly mixed with other dry ingredients to ensure optimal performance.
