Stearic Acid, or Octadecanoic Acid (CAS 57-11-4), is a versatile saturated fatty acid with a broad spectrum of applications. However, not all Stearic Acid is created equal. The specific grade chosen is crucial for optimal performance in diverse industries, from delicate cosmetic formulations to robust industrial processes. As a seasoned manufacturer and supplier based in China, we offer a comprehensive range of Stearic Acid grades to meet your precise requirements.

Understanding the different grades of Stearic Acid is key to successful product development and manufacturing:

1. Cosmetic Grade Stearic Acid: This grade demands the highest purity, typically exceeding 99%, with very low levels of impurities. It is specifically formulated for use in skincare products, shampoos, lotions, and soaps where direct skin contact is involved. Its emulsifying, thickening, and stabilizing properties are essential for creating stable and luxurious personal care items. We supply premium cosmetic grade Stearic Acid powder and flakes for this discerning market.
2. Food Grade Stearic Acid: Meeting stringent regulatory standards like those set by the FDA or EFSA, food grade Stearic Acid is used as a food additive (E570), primarily as a lubricant, anti-foaming agent, and as a raw material for producing other food emulsifiers. Its purity is critical to ensure safety and compliance in edible products.
3. Industrial Grade Stearic Acid: This grade is characterized by its broad applicability in sectors like plastics, rubber, and paints. While still maintaining good purity, it may have a wider range of fatty acid compositions compared to cosmetic or food grades. Its primary functions here include lubrication, stabilization (especially in PVC), and acting as a mold release agent. We offer industrial grade Stearic Acid in various forms, including beads and granular options, at competitive wholesale prices.
4. Rubber Grade Stearic Acid: A specialized industrial grade, this Stearic Acid is optimized for use in rubber processing. It acts as a vulcanization activator and softener, improving the flow properties of rubber compounds during manufacturing and enhancing the final product's flexibility and durability.

The manufacturing location and supplier's expertise significantly influence the quality and cost-effectiveness of Stearic Acid. As a leading Chinese manufacturer, we leverage advanced production technologies and rigorous quality control systems to produce Stearic Acid that meets international standards across all grades.
