Chemical Structure

Oleyl Alcohol CAS 143-28-2 Manufacturer | Cosmetic & Industrial Grade | Zhishang Chem

Basic Info

Oleyl Alcohol (CAS Registry Number: 143-28-2), systematically named cis-9-octadecen-1-ol, is a long-chain unsaturated fatty alcohol featuring an eighteen-carbon structure with a central cis double bond. Defined by the chemical formula C18H36O, this non-ionic oleochemical appears as a clear, colorless to pale yellow oily liquid that remains fluid at ambient room temperatures, unlike its saturated counterparts such as stearyl alcohol or cetyl alcohol.
 
At Shandong Zhishang Chem Co., Ltd., our Oleyl Alcohol is produced through selective hydrogenation and precision fractional distillation of vegetable-derived fatty acids. This process yields an optimal balance between unsaturated C18 content and low oxidation potential. Oleyl Alcohol serves as a multifunctional emollient, coupling solvent, skin penetration enhancer, viscosity modifier, and chemical intermediate across personal care cosmetics, topical pharmaceutical formulations, textile auxiliaries, and high-performance metalworking lubricants.

Product Packaging

Oleyl Alcohol provides a distinct combination of lipophilic fluidity, surface activity, and film-forming characteristics that make it valuable across multiple commercial sectors:
 
Personal Care & Cosmetics: Functions as a rich, non-greasy emollient, pigment dispersant, and coupling agent in lipsticks, skin lotions, creams, hair conditioners, and color cosmetics, imparting a silky feel and improving product spreadability.
 
Topical Pharmaceuticals & Transdermal Delivery: Acts as an effective transdermal penetration enhancer, disrupting lipid bilayers safely to increase active ingredient absorption in creams, ointments, and gel patches.
 
Specialty Solvents & Coupling Agents: Serves as a carrier and co-solvent for oil-soluble active ingredients, fragrances, and botanical extracts in clear anhydrous formulations.
 
Industrial Lubricants & Textile Auxiliaries: Utilized as a friction-reducing additive, emulsifier intermediate, and anti-wear lubricity agent in metal processing fluids, textile softening auxiliaries, and plasticizer synthesis.

FAQ

A1: Because of the cis double bond in its molecular chain, Oleyl Alcohol remains a liquid at room temperature. This liquid state allows it to provide rich emolliency, pigment coupling, and penetration enhancement in liquid and cold-processed formulations without requiring melting or thermal processing.

A2: Oleyl Alcohol should be stored in original sealed drums under an inert nitrogen blanket in a dry, cool warehouse away from direct heat, sunlight, and strong oxidizing agents. Under proper storage conditions below 25 degrees Celsius, its shelf life is 24 months from the manufacturing date.

A3: Yes. Our Oleyl Alcohol is derived 100% from vegetable oil sources, making it fully suitable for vegan, cruelty-free, and clean-label cosmetic product lines.

A4: Standard packaging options include 170 kg steel drums, 20 kg plastic drums, and 850 kg IBC totes. Custom sample containers are available upon request for laboratory trial evaluations.

Quality Management & International Certifications

To meet stringent international compliance requirements for personal care ingredients and industrial oleochemicals, Shandong Zhishang Chem operates under unified quality assurance protocols:
 
ISO 9001:2015 Quality Management Framework: Full end-to-end quality tracking from raw vegetable oil sourcing through hydrogenation, fractionation, and nitrogen-sealed drumming.
 
EU REACH Registration Compliance: Complete technical dossier support and tonnage coverage available for European Union cosmetics and industrial buyers.
 
Plant-Based & Sustainable Sourcing: Derived exclusively from natural vegetable feedstocks, free from animal-derived contaminants, and supporting sustainable palm/vegetable oil supply chain standards.
 
Cosmetic Safety Standards Alignment: Produced under sanitary manufacturing conditions to keep heavy metal, residual solvent, and pesticide trace levels strictly below international safety limits.
Unsaturated fatty alcohols require tight controls over oxidation stability and carbon chain purity to ensure long-term formulation clarity and prevent odor development. Every production batch of Oleyl Alcohol passes through a four-stage internal testing sequence before releasing the official Certificate of Analysis:
 
Gas Chromatography Carbon Chain Profiling (GC-FID): Verifies the exact C18:1 unsaturated oleyl alcohol percentage while limiting saturated alcohol impurities like cetyl and stearyl alcohols.
 
Iodometric Titration for Unsaturation Verification: Accurately checks the double-bond density via iodine value determination, guaranteeing consistent fluidity and solvency performance.
 
Peroxide Value & Acid Value Analysis: Checks oxidation stability to ensure the product is free from rance-causing peroxides or free fatty acids, ensuring long shelf life in personal care formulations.
 
Physical Cloud Point & Refractive Index Verification: Measures low-temperature liquid transparency and optical consistency across batch samples.
