Properties of 1. octadecanol

octadecanol, also known as stearyl alcohol (Stearyl Alcohol), is a long chain fatty alcohol with the formula C18H38O. It appears as a white waxy solid at room temperature, with low toxicity and low volatility. Octadecanol has good lubricity, emulsification and thickening properties, which make it widely used in many fields. The melting point is about 58 ° C., the boiling point is 210 ° C., the solubility in water is very low, but soluble in ethanol, ether and other organic solvents.

Use of 2. octadecanol

the main uses of octadecanol can be summarized in the following aspects:

cosmetics and Personal Care Products: Due to its good emollient and moisturizing properties, octadecanol is widely used in skin care products, shampoos, hair conditioners and lip balms as emulsifiers, thickeners and stabilizers.
pharmaceutical industry: In the pharmaceutical field, octadecanol is often used as a pharmaceutical excipient, especially in the preparation of ointments and emulsions, which plays an emulsifying and thickening role.
plastics and rubber industry: Octadecanol can be used as a lubricant and plasticizer to improve the processing performance and surface quality of plastic and rubber products.
Textile and leather industry: As a softener and lubricant, octadecanol can improve the feel and gloss of textiles and leather.

Upstream feedstock for 3. octadecanol

the production of octadecanol is mainly carried out by chemical synthesis and natural extraction:

chemical synthesis: Octadecanol is often prepared industrially by hydrogenation of fatty acids or reduction of fatty acid esters. The raw material fatty acids are mostly derived from the cleavage products of vegetable oils or animal fats.
natural extract: Natural octadecanol is usually extracted from vegetable oils such as coconut oil and palm oil. Octadecanol produced in this way generally has higher purity and better biocompatibility.

Downstream products of 4. octadecanol

as an important chemical raw material, octadecanol's downstream products mainly include:

cosmetics and Personal Care Products such as all kinds of skin cream, facial cleanser, shampoo, conditioner, etc.
Drugs such as ointment, cream, ointment and other pharmaceutical preparations.
Industrial Products such as lubricants, plasticizers, softeners, etc.

These downstream products are widely used and the market demand is large, which drives the production and sales of octadecanol.

Storage Method of 5. Octadecanol

the storage of octadecanol requires attention to the following points:

temperature control: Octadecanol is solid at room temperature, and the storage temperature should be kept at a low level to prevent it from melting. Storage temperatures below 20°C are generally recommended.
Moisture-proof measures: Although the hygroscopicity of octadecanol is not strong, in order to prevent it from being affected by moisture, it should be kept dry during storage and avoid contact with moisture.
Sealed packaging: Octadecanol should be stored in a sealed container to prevent it from contacting impurities in the air and avoid oxidation and pollution.
Fireproof and explosion-proof: Although octadecanol has a high ignition point, it is still necessary to avoid high temperature and fire sources to prevent accidental fires. In addition, it should be stored in a well-ventilated warehouse to prevent the accumulation of combustible gas from causing an explosion.

6. market prospect and development trend

with the increasing demand for cosmetics and personal care products, the market demand for octadecanol is also growing. Increased awareness of green environmental protection has also contributed to the increase in the market share of octadecanol from natural sources. In the future, the application of octadecanol in high value-added fields such as new materials and biomedicine is expected to be further expanded.

In summary, octadecanol has been widely used in many fields due to its unique physical and chemical properties. With the progress of technology and the change of market demand, the production process and application range of octadecanol will continue to expand, and the prospect is very broad.
