Oleic Acid

## Oleic Acid (CAS 112-80-1): Key Functions and Uses

1. **Versatile Monounsaturated Fatty Acid**
Oleic Acid is a C18:1 monounsaturated fatty acid, commonly classified as an **omega-9 fatty acid**. Its long hydrophobic chain and carboxylic acid group give it useful emulsifying, lubricating, solubilizing, and surface-active properties.

2. **Emulsifier and Solubilizing Agent**
Oleic Acid helps blend oil-soluble and water-compatible ingredients in selected formulations. It is used in emulsions, creams, lotions, coatings, aerosols, and other systems where improved dispersion, solubility, or formulation stability is required.

3. **Cosmetic and Personal-Care Ingredient**
In suitable cosmetic grades, Oleic Acid functions as an emollient, conditioning agent, surfactant, and carrier for skin-care and hair-care formulations. It can contribute to skin feel, spreadability, and the delivery of oil-soluble components.

4. **Pharmaceutical Excipient and Formulation Aid**
Pharmaceutical-grade Oleic Acid may be used as an excipient, solubilizer, emulsifying component, or carrier in selected topical, oral, and lipid-based formulations. Its use depends on purity, oxidation stability, dosage form, and applicable pharmacopeial requirements.

5. **Soaps, Surfactants, and Oleate Derivatives**
Oleic Acid is an important raw material for producing oleates, soaps, surfactants, detergents, and specialty esters. These derivatives are used in cleaning products, textiles, coatings, lubricants, and industrial formulations.

6. **Lubricants and Metalworking Applications**
Oleic Acid can function as a lubricant, friction modifier, dispersant, or additive in metalworking fluids and industrial lubricant systems. It may also support ore flotation, corrosion-control research, rubber processing, and surface-treatment formulations.

7. **Polymer, Plasticizer, and Biofuel Research**
Oleic Acid is used as a feedstock or intermediate for plasticizers, epoxidized oleates, polymer modifiers, biodiesel, and other oleochemical products. Its reactivity enables esterification and further chemical conversion into value-added materials.

8. **Quality, Procurement, and Safety Considerations**
When sourcing Oleic Acid 112-80-1, buyers should verify fatty-acid composition, assay, iodine value, acid value, peroxide value, oxidation stability, moisture, color, source, grade, packaging, and certificate of analysis. Useful SEO keywords include **Oleic Acid, CAS 112-80-1, omega-9 fatty acid, emulsifier, surfactant, cosmetic ingredient, pharmaceutical excipient, lubricant additive, oleate ester, biodiesel raw material, and industrial fatty acid**. Users should select a grade suitable for the intended application and follow the supplier’s Safety Data Sheet and applicable regulations.
