Stearyl alcohol, or 1-octadecanol, is an organic compound classified as a saturated fatty alcohol with the formula CH3(CH2)16CH2OH.

Stearyl alcohol is an organic compound in the form of white crystalline granules, derived from fats and oils

Stearyl alcohol is a fatty alcohol sold in flakes, pastilles, and beads.

Stearyl alcohol helps to emulsify the active ingredient and fragrance in deodorants and antiperspirants.

Stearyl alcohol also helps modify the physical texture of the stick’s waxy base.

Stearyl alcohol takes the form of white granules or flakes, which are insoluble in water. 

Stearyl alcohol is mostly used as an ingredient in lubricants, perfumes, resins, and cosmetics.

Stearyl alcohol is in a class known as fatty alcohols, which, unlike irritating types of alcohols, do not dry out the skin. 

Stearyl alcohol is an emollient to soften the skin, while also working as an emulsifier to help oil and water combine and give products a smooth consistency

Stearyl alcohol is a natural alcohol-based thickener of cosmetic products, mainly creams, lotions, and antiperspirants. 

Stearyl alcohol changes the viscosity and adds a to creams and lotions, whilst adding stability

 

Stearyl alcohol acts as an emollient, leaving the skin feeling smooth and soft by forming a protective layer on the surface and helping to prevent moisture loss.

Stearyl alcohol has a wide range of uses as an ingredient in lubricants, resins, perfumes, and cosmetics. 

Stearyl alcohol is used as an emollient, emulsifier, and thickener in ointments, and is widely used as a hair coating in shampoos and hair conditioners. 

Stearyl heptanoate, the ester of stearyl alcohol and heptanoic acid (enanthic acid), is found in most cosmetic eyeliners. 

Stearyl alcohol has also found application as an evaporation-suppressing monolayer when applied to the surface of water.

Stearyl alcohol is prepared from stearic acid or some fats by the process of catalytic hydrogenation. It has low toxicity.

Stearyl alcohol is a long-chain primary fatty alcohol consisting of a hydroxy function at C-1 of an unbranched saturated chain of 18 carbon atoms. 

Stearyl alcohol has a role as a plant metabolite, a human metabolite, and an algal metabolite. 

Stearyl alcohol is a long-chain primary fatty alcohol, a fatty alcohol 18:0, and a primary alcohol. It derives from a hydride of an octadecane.

Stearyl alcohol is one of the most promising fatty alcohols to be used for food applications as an oil-structuring agent.

Stearyl alcohol can be used in personal care products as an emollient, helping to nourish skin and hair, leaving them soft and smooth. 

Stearyl alcohol also has emulsion-stabilizing properties and can be used to help balance and add structure to oil-water formulations.

Stearyl alcohol is typically produced through hydrogenation (process change from a liquid into a solid or semi-solid state) of stearic acid. 

Stearic acid is a saturated fatty acid prevalent in animal fats, but rich plant sources of stearic acid include palm fruit, cocoa butter, and shea butter.
