Metallic Stearates Market: Introduction
In terms of value, the global metallic stearates market is anticipated to expand at a CAGR of ~5% from 2020 to 2030. Metallic stearates are used as acid scavengers, lubricants, and release agents in the plastics industry. PVC (polyvinyl chloride) is one of the oldest and widely used plastics. It is durable and light, and exhibits low permeability. It is fire resistant, and offers good insulation properties. PVC rarely absorbs water and is stable toward acid, alkali, alcohol, oil, and petrol. It is difficult to convert PVC; therefore, processing additives are needed to improve the melting viscosity and the flow properties of PVC. Metallic soaps are vital additives for PVC, as they offer excellent stabilizing and lubricating properties.
Calcium and zinc (CaZn) stearates are considered ideal heat stabilizers for PVC production. They are primarily employed to prevent degradation of plastics by heat, especially during processing. Currently, CaZn-based heat stabilizers are employed in various applications, especially those requiring nontoxic properties, such as medical and food packaging. Additionally, solid CaZn heat stabilizers are highly useful for interior applications requiring low VOCs. CaZn heat stabilizers are also being increasingly considered as more environment-friendly alternatives to BaZn and Tin stabilizers.
Side Effects of Magnesium Stearates to Hamper Metallic Stearates Market
Magnesium stearate is an additive that is primarily used in medication capsules. It is considered a flow agent. It helps prevent the ingredients in a capsule from sticking to each other. It also helps improve the consistency and quality control of medication capsules. The U.S. Food and Drug Administration (FDA) has approved magnesium stearate for usage as an additive in food and medications. According to the National Center for Biotechnology Information, magnesium stearate is considered safe for consumption at amounts below 2,500 milligrams (mg) per day. For a 150-pound adult, that equals 170,000 mg per day. However, in a few cases, magnesium stearates exhibit side effects.
Some people may experience allergy symptoms after consuming foods or supplements containing magnesium stearate. It can have a laxative effect, meaning it can irritate the mucosal lining of an individual’s bowels. This causes the bowels to spasm, thus causing a bowel movement or even diarrhea.

Sodium Stearates to Offer Growth Opportunities
In terms of type, the global metallic stearates market has been divided into aluminum stearates, calcium stearates, magnesium stearates, zinc stearates, sodium stearates, and others. Sodium stearates is projected to be a highly lucrative segment of the global metallic stearates market during the forecast period. It is likely to expand at a CAGR of 4% from 2020 to 2030. Sodium stearate is a major constituent of most vegetable-based soaps, owing to its consistency. In a deodorant, it has the unique ability to form a structure with other materials such as vegetable propylene glycol, glycerin, and propanediol to produce a solid stick shape.
Powder Form to Dominate Metallic Stearates Market
In terms of form, the global metallic stearates market has been classified into granular, powder, prills, flakes, pellets, and pastilles. In terms of value and volume, the powder segment constituted a significant share of the global metallic stearates market in 2019. Powdered metallic stearates are extensively used in pharmaceuticals. This is estimated to drive the powder segment in the near future.
Plastics & Rubbers to be Key Application
In terms of application, the global metallic stearates market has been segregated into plastics & rubbers, food, pharmaceutical, paints & varnishes, building materials, cosmetics, lubricants & detergents, and others. The plastic & rubber segment is anticipated to dominate the market during the forecast period. Metallic stearates are used as dry lubricants in various applications. In the plastics industry, they are added to resin (PVC type) granules to provide lubrication and mold release in injection molding applications. Good lubricity, hydrophobicity, compatibility, and melt point possessed by metallic stearates help provide the necessary performance in the plastic & rubber industry. This is expected to boost the global metallic stearates market in the near future.
