12-Hydroxystearic Acid CAS 106-14-9
What is 12-hydroxystearic acid?
12-hydroxystearic acid is extracted from plant oils (such as castor oil) through advanced hydrogenation and refining processes. It is a valuable raw material that combines natural properties with multifunctional advantages. It is used in the chemical, daily chemical, and pharmaceutical industries.
Key Properties of 12-hydroxystearic acid
The unique properties of 12-hydroxystearic acid are primarily due to its molecular structure:
Polar functional groups: One end of the molecule is a carboxylic acid group (-COOH), and the middle is a hydroxyl group (-OH). These two polar groups give it a strong ability to form hydrogen bonds.
Long carbon chain: The rest of the molecule is a long alkyl chain, which is hydrophobic (lipophilic).
This structure (with both a hydrophilic head and a hydrophobic tail) gives it the following key properties:
Excellent thickening ability: This is its most important characteristic. When it reacts with metal hydroxides (such as lithium hydroxide), it forms a unique fibrous or soap fiber structure. These fibers entangle within the base oil, forming a three-dimensional network that securely locks in the oil, resulting in a superior grease.
High Melting Point: Due to strong intermolecular hydrogen bonding, 12-hydroxystearic acid has a high melting point (approximately 78-82°C), which helps to improve the dropping point of the grease produced from it.
Good Chemical Stability: The saturated alkyl chain makes it more stable than unsaturated fatty acids and less susceptible to oxidation and deterioration.

Main Applications of 12-Hydroxystearic Acid
Daily Chemical Industry: Improving Product Stability and User Experience
In skincare products such as face creams and hand creams, 12-hydroxystearic acid acts as a highly effective emulsifier and stabilizer, effectively promoting the uniform blending of the oil and water phases and preventing product separation or clumping. Its properties contribute to the formation of a fine paste structure, enhancing smooth application and absorption, thereby alleviating the problems of some skincare products such as difficulty in spreading and rubbing.
In shampoo and body wash formulas, this ingredient provides both thickening and conditioning properties, enhancing the richness and density of the foam. It also helps moisturize the skin and hair after cleansing, preventing tightness. Therefore, it is particularly suitable for high-end cleansing and care products that emphasize amino acid formulas or silicone-free properties, achieving a balance between cleansing power and mildness.
Lubrication and Chemical Industries: Enhancing Material Performance and Durability
A key raw material for greases, 12-hydroxystearic acid reacts with metal soaps (such as lithium and calcium soaps) to produce greases with high dropping points and anti-aging properties. These greases maintain structural stability under harsh operating conditions such as high temperature and high pressure, resisting melting or loss. They are widely used in automotive bearings, mechanical gears, and motors, helping to extend equipment life and reduce maintenance costs.
In plastics processing, this ingredient acts as a lubricant and dispersant, effectively reducing frictional resistance of plastic particles during the molding process and improving the surface finish of finished products. It also promotes uniform dispersion of pigments and fillers, preventing color spots and color variations, thereby improving the appearance and overall performance of plastic products.
Pharmaceutical and Food Industries: Functional Excipients
In pharmaceutical manufacturing, 12-hydroxystearic acid is often used as a pharmaceutical excipient in dosage form design. For example, in capsule shell formulations, it can be used to adjust disintegration time, enabling targeted drug release in the intestine. In ointments and suppositories, it serves as a matrix component, ensuring uniform drug distribution and enhancing the stability of drug efficacy.
In the food industry, food-grade certified 12-hydroxystearic acid is used as an emulsifier and stabilizer in products such as chocolate, candy, and baked goods. Its functions include preventing oil precipitation, improving food texture, and effectively extending shelf life, making it particularly suitable for foods that require long-distance transportation or long-term storage.
