What is 12-Hydroxystearic Acid (12-HSA)?

12-Hydroxystearic acid (12-HSA) is an off-white solid fatty acid that comes from castor oil through a process called hydrogenation. It's mainly used to make lithium and calcium-based lubricating greases.

12-HSA is also the main element in coatings and resins that helps to give a strong finish to products in the automotive as well as small appliance sector.

12-Hydroxy Stearic Acid Structure Structure

12-HSA is an off-white solid fatty acid which is commonly used in the production of lithium and calcium lubricating greases. When combined with esters, it forms hard finishes suitable for automotive and small appliance applications

Applications & Uses of 12-Hydroxy Stearic Acid

Industrial and Commercial Uses:

Car and Truck Greases

12-HSA soaps are key parts in mineral oil-based multi-purpose greases. This means the same grease can be used in different parts of cars and trucks, reducing complexity and maintaining good results.

Paint and Coatings

In paints, 12-HSA mixes with acrylic esters to make hard, long-lasting polymers. These are used in high-quality car finishes, industrial equipment coatings, and decorative metal treatments.

Rubber Making

In rubber making, 12-HSA works as both an activator and internal lubricant for natural and synthetic rubbers. This helps during making and improves the final product.

Plastics and Chemical Making

12 hydroxy stearic acid uses include plastics lubrication and as a raw material for making more complex chemicals. It also acts as a high-hydroxyl castor-based wax component.

Beauty Products

In cosmetics, 12-HSA works as a gel-making agent for liquid petroleum products to make them shiny. It mixes into cold creams and vanishing creams to create a jelly-like feeling that users like.

Grease Making

12 HSA manufacturers in India use 12-HSA to make greases stronger and more stable. 12-HSA-based greases provide the dual benefits of sodium greases’ heat tolerance and calcium greases’ water resistance. Adding 12-HSA makes greases work better with improved texture, better heat stability, and higher dropping points.

12-Hydroxy Stearic Acid HS Code & Rules

The HS code for 12-hydroxystearic acid is 2918.19.90, listed under ‘Other saturated acids and their derivatives.’ This code is used in customs papers to make imports and exports hassle-free 12-hydroxystearic acid suppliers worldwide use this code to follow trade rules and ship products safely across countries

12 hydroxy stearic acid uses include making lithium and calcium-based greases for automotives, beauty products, hard polymer coatings, rubber processing, and plastic lubrication. The hydroxyl group helps it to perform better under heat and in chemical processes.
The 12 hydroxy stearic acid HS code is 2918.19.90, used for customs classification and international trade papers by suppliers and importers internationally.
12-HSA is made by treating castor oil with hydrogen at room temperature under 40 psi pressure with alcohol. The resulting hydrogenated castor oil goes through soap-making with NaOH solution, then acid treatment to get pure 12-HSA.
Yes, 12-HSA is considered biodegradable since it is derived from castor oil and has a fatty acid structure that can break down naturally. It is generally safer for the environment than many synthetic alternatives, though proper disposal rules should still be followed.
