What is Oleylamine?

Oleylamine is a long-chain organic amine with a chemical formula usually expressed as C18H37N or C18H34NH3, also known as 9-octadecylamine. It is a C18 unsaturated amine obtained from the reaction of oleic acid and ammonia. It is a colorless to light yellow liquid or crystalline state with a pungent odor and certain corrosiveness. The melting point of oleylamine ranges between 18-26°C, the boiling point is about 348-350°C, and the relative density is 0.813. It is insoluble in water, but can be well soluble in a variety of organic solvents, such as ethanol, acetone, carbon tetrachloride, chloroform, isopropyl alcohol, kerosene, methanol, toluene and white mineral oil.

Oleylamine Uses

Catalyst and Stabilizer: In chemical synthesis, oleylamine can be used as a catalyst or catalyst stabilizer, especially in polymerization reactions (such as ethylene polymerization). It can control the morphology and molecular weight distribution of the polymer and improve reaction efficiency.

Nanomaterial synthesis: In the field of nanotechnology, oleylamine serves as a surfactant and participates in the synthesis of metal nanoparticles (such as gold, silver, platinum, etc.) to help control the size, shape and dispersion of particles and prevent particle agglomeration. It is widely used in Catalysts, electronic materials and pharmaceutical fields.

Quantum dot preparation: In the synthesis of quantum dots, oleylamine serves as a ligand to help form high-quality semiconductor nanocrystals by controlling crystal growth, which is crucial for optoelectronics and biomarking applications.

Surface modification: As a surfactant, oleylamine can improve the surface properties of substances, such as increasing hydrophobicity or changing wettability. Therefore, it plays a role in the surface treatment of coatings, plastics, fibers, paper and other materials to improve their performance and Durability.

Biomedicine: In the field of biomedicine, oleylamine can be used in drug delivery systems as a drug carrier or auxiliary material to help drugs cross cell membranes and improve bioavailability; it is also an intermediate in the synthesis of certain drugs.

Metal extraction and recovery: In the metallurgical industry, oleylamine is used as a flotation agent for the extraction and recovery of precious metals (such as gold and silver). It separates metal ions through selective adsorption and improves recovery rate and purity.

Pesticides and cosmetics: In pesticide formulations, oleylamine is used as an auxiliary to enhance the adhesion and permeability of pesticides; in the cosmetics industry, due to its good moisturizing and emulsifying properties, it is used as an ingredient in skin care products to help form a protective film , reduce water loss.

Analytical Chemistry: As a chemical reagent, oleylamine is used as an extractant or reaction medium in some analytical methods to aid in the separation and determination of specific compounds.

Prominent Applications of Oleylamine in Cosmetics

Emulsifiers and stabilizers: As a nonionic surfactant, oleylamine can effectively reduce the interfacial tension between water and oil phases and help form a stable emulsion system. It is widely used in various types of lotions and cream cosmetics (such as facial creams, sunscreens, etc.) , isolation cream), improve the uniformity and stability of the product, making the product fine in texture, easy to apply and feel refreshing.

Moisturizing and moisturizing: Oleamine has certain lipophilicity and hydrophilicity, which can form a protective film on the surface of the skin to help lock in moisture, reduce evaporation, and achieve a moisturizing effect. For dry skin, it can provide necessary moisture, improve dryness, and make skin soft and smooth.

Cleansing and decontamination: In cleansing products and makeup remover oils, oleylamine can dissolve oil and makeup on the skin surface. Its mild nature reduces skin irritation and is suitable for sensitive skin. It can also help maintain the skin’s natural lipids. Barrier to avoid dryness and tightness caused by over-cleansing.

Film-forming agent: In nail polish and other products that require the formation of a protective film, oleylamine can help form a continuous and elastic film, enhancing the gloss and durability of the product while protecting nails from external damage.

Antistatic agent: In hair care products, oleylamine can reduce static electricity in the hair, improve the combability of the hair, and make the hair look smoother and easier to manage. By forming a thin protective layer on the hair surface, it can also help lock in the hair’s moisture and reduce moisture loss.

Auxiliary ingredients: In cosmetic formulations, oleylamine is sometimes used as an auxiliary ingredient to help improve the solubility and stability of other active ingredients and promote their ability to penetrate the skin, thus enhancing the overall effect of the product.
