12 HCA

12 HCA

In the context of castor oil derivatives, 12-HCA is often used as an alternative abbreviation for 12-Hydroxystearic Acid (12-HSA). It is a high-purity, waxy solid derived through the hydrogenation of ricinoleic acid, the primary component of castor oil.

  • Appearance: Typically found as white to off-white solid flakes or powder.
  • Chemical Identity: A saturated C18 fatty acid with a hydroxyl group on the 12th carbon (CAS No. 106-14-9).
  • Melting Point: High for a fatty acid, usually between 72°C and 78°C.
  • Solubility: Insoluble in water but soluble in many organic solvents like ethanol and chloroform.

Major Applications in 2026

  • Lubricating Greases: It is a critical raw material for manufacturing lithium and calcium-based multipurpose greases. It provides these greases with excellent water resistance and heat stability (high dropping points).
  • Cosmetics & Personal Care: 12-HCA acts as a thickener, stabilizer, and emollient. It is widely used in creams, lotions, and deodorants to create a smooth, luxurious texture without irritation.
  • Polymers & Coatings: When reacted with acrylic esters, it produces durable thermosetting polymers used for high-quality automotive finishes and industrial equipment coatings.
  • Rubber & Plastics: Functions as an internal lubricant and processing aid for both natural and synthetic rubbers, improving flexibility and mold release.
  • Textiles: Used as a finishing agent to provide fabrics with a smooth texture and increased durability

Why It Is Preferred

  • Eco-Friendly: As a vegetable-derived oleochemical, it is a sustainable and biodegradable alternative to petroleum-based chemicals.
  • Non-Toxic: It is generally classified as a low-risk, safe compound for use in products that come into direct contact with skin.
