INCI name:Stearyl Alcohol
CAS Number: 112-92-5

Stearyl alcohol also known as 1-octadecanol is a fatty alcohol classified as a saturated fatty alcohol with the formula CH₃(CH₂)₁₆CH₂OH used as an emollient and to help keep other ingredients intact in a formulation. Stearyl alcohol is a thickener of cosmetic products, mainly creams, and lotions. It is typically produced through hydrogenation (process change from a liquid into a solid or semi-solid state) of stearic acid. Stearyl alcohol is a natural alcohol. It changes the viscosity and adds a to creams and lotions, whilst adding stability. Stearyl Alcohol helps to form emulsions and prevent an emulsion from separating into its oil and liquid components. These ingredients also reduce the tendency of finished products to generate foam when shaken.

Uses & Benefits:
Stearyl alcohol has a wide range of uses as an ingredient in lubricants, resins, perfumes, cosmetics, shampoos, conditioners, and cosmetics. Stearyl alcohol functions as an adjuvant emulsifier ensuring that oil and water can be blended so that products ultimately feel thicker and more cosmetically pleasing and makes the cream smoother. It takes the form of white granules or flakes, which are insoluble in water.
In cosmetics, alcohol is used for its high volatility (it disappears immediately after application), its drying and refreshing properties. It facilitates the penetration of active ingredients into the superficial layers of the skin and promotes the deposit of ingredients on the skin or hair.
Not only is it considered safe and non-toxic for use on the skin and hair, but it's also not drying or irritating like other types of alcohol. Due to its chemical structure, Stearyl alcohol is even permitted by the FDA as an ingredient in products labeled “alcohol-free.”
Appearance:
Stearyl alcohol is also known as 1-octadecanol, and in its raw form is a white, waxy substance.
