Stearyl Alcohol is a pure and natural fatty alcohol from the fatty acid of Coconut Oil. The fatty alcohols are not at all similar to what you might think of when you think of alcohol, from petro or even the natural distilled grains, which would be drying to the skin.
Stearyl Alcohol and other Fatty Alcohols, in contrast, are very moisturizing to the skin where they help to lock in the skin's natural moisture levels, and impart a smooth, soft, feel to both the product and the skin.
Stearyl Alcohol can be usefully employed in your emulsions, and anhydrous formulas to increase viscosity (thicken), and to give the product a cushioned body.
Stearyl Alcohol is one of the most widely used of the natural fatty alcohols, often employed as the sole conditioning agent in natural creme rinse or natural hair conditioners, as it adequately moisturizes and improves wet / dry comb out.
A natural, and easy to use, rheology modifier that will improve the texture of all formulas that contain an oil phase, where Stearyl Alcohol delivers a 'conditioned' feel to the skin.
Stearyl Alcohol NF is also a good choice when you're looking for a natural thickener, where it also provide a rich, smooth, emulsion.
Stearyl Alcohol is also, commonly, used as a natural thickener, which improves the stability of the emulsion to function, as a co-emulsifier, and it is compatible with almost all common cosmetic ingredients.
When Stearyl Alcohol is used as the thickener in your formulation, as opposed to other natural thickener choices, it offers more ease of use because it won't impact the system pH, or add thixotropic behavior.
A great choice when you optimize your formulas to strip out incidental ingredients for greener formulations. As a thickener Stearyl Alcohol offers simplicity.
When compared to Cetyl Alcohol in formulation the Stearyl Alcohol will deliver a softer end product with a whiter appearance.
Stearyl alcohol is a vegetable derived long chain fatty alcohol.
Stearyl alcohol is commonly found in a wide variety of skin care and cosmetic products.
What does it do?
Stearyl alcohol has emollient properties and also can function as an emulsifier and thickener in products.
In stick products, such as deodorants and antiperspirants, Stearyl alcohol helps to emulsify the active ingredient and fragrance into the wax base.
Stearyl alcohol also helps modify the physical texture of the stick’s waxy base.
Octadecan-1-ol 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 is a long-chain primary fatty alcohol, a fatty alcohol 18:0 and a primary alcohol.
Stearyl alcohol derives from a hydride of an octadecane.
Stearyl Alcohol, Oleyl Alcohol and Octyldodecanol are long chain fatty alcohols.
Stearyl Alcohol is a white, waxy solid with a faint odor, while Oleyl Alcohol and Octyldodecanol are clear, colorless liquids.
These three ingredients are found in a wide variety of products such as hair conditioners, foundations, eye makeup, skin moisturizers, skin cleansers and other skin care products.
Why is Stearyl Alcohol used in cosmetics and personal care products?
Stearyl Alcohol, Oleyl Alcohol and Octyldodecanol help 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.
When used in the formulation of skin care products, Stearyl Alcohol, Oleyl Alcohol and Octyldodecanol act as a lubricants on the skin surface, which gives the skin a soft, smooth appearance.
Stearyl Alcohol and Oleyl Alcohol are mixtures of long-chain fatty alcohols.
Stearyl Alcohol consists primarily of n-octadecanol, while Oleyl Alcohol is primarily unsaturated 9-n-octadecenol.
Octyldodecanol is a branched chain fatty alcohol. Fatty alcohols are higher molecular weight nonvolatile alcohols.
They are produced from natural fats and oils by reduction of the fatty acid (-COOH) grouping to the hydroxyl function (-OH).
Alternately, several completely synthetic routes yield fatty alcohols which may be structurally identical or similar to the naturally-derived alcohols.
Stearyl Alcohol is emollient and viscosity controlling agent is cosmetics products.
Stearyl Alcohol has emulsifying, surfactant/cleansing and emulsion stabilising properties.
Stearyl Alcohol is a handy multi-tasker, white to light yellowish oil-loving wax that works very well in oil-in-water emulsions.

What is Stearyl alcohol?
Stearyl alcohol is an organic compound that is classified as a fatty alcohol.
Stearyl alcohol is a white, waxy granule or flake, which doesn’t dissolve in water.
Stearyl alcohol is derived from stearic acid which is most commonly found in vegetable, palm and coconut oils.
Stearyl alcohol is often used in hair shampoos and conditioners, moisturisers, make up, cleansers, perfumes and foundation.
What does it do?
Stearyl alcohol is used as an ingredient in a wide variety of skin care and cosmetics.
Stearyl alcohol has a number of uses including acting as an emollient, an emulsifier, and a thickener in ointments.
As an emulsifier Stearyl alcohol helps stop products from separating into their oil and water components.
Despite alcohols being associated with drying the skin, as an emollient it acts as a lubricant in moisturisers. Stearyl alcohol helps give the skin a smoother and soft appearance.
Stearyl alcohol is also added to products as it helps stop them from being overly foamy or bubbly, especially if they are dropped or shaken.
Stearyl alcohol is regarded as a safe ingredient. Stearyl alcohol is a low hazard, low irritant ingredient with low toxicity.

Stearyl alcohol is a natural fatty alcohol that is used as an emollient, emulsifier, and thickener in a variety of cosmetics and personal care products.
Stearyl alcohol also referred to as octadecyl alcohol or 1-octadecanol, is an organic compound that is classified as a fatty alcohol.
Fatty alcohols are a hybrid between alcohols and fatty acids or oils. This makes them highly versatile skincare ingredients.
Stearyl alcohol is derived from stearic acid, a natural saturated fatty acid, by the process of catalytic hydrogenation.
Catalytic hydrogenation is a process of adding hydrogen atoms to a molecule using a metal as a catalyst.
Stearyl alcohol takes the form of white granules or flakes, which are insoluble in water.
Stearyl alcohol is most commonly used in beauty products such as moisturizers, ointments, shampoos, masks, exfoliators, some cosmetics, and hair conditioners.
Stearyl alcohol is derived from coconut and palm kernel oils. The oils are converted to alcohol, distilled and hydrogenated into stearyl alcohol.
Oil-in-water emulsions used in many pharmaceutical creams are not stabilized by the surfactant mechanical properties but rather stabilized by forming a gel network consisting of the structure-forming agents such as stearyl alcohol, cetyl alcohol, cetostearyl alcohol, etc.
Stearyl Alcohol helps to improve the texture of products, reduce moisture loss from the skin and protect the skin from allergens and bacteria
Stearyl alcohol is often misunderstood because of its name. Stearyl alcohol is a non-drying ingredient.
Due to its name, stearyl alcohol is often misunderstood to be harmful to the skin since it is an alcohol.
It is true that some alcohols, like ethyl or rubbing alcohol, can be extremely drying to the skin.
However, quite the opposite is true for stearyl alcohol, which is well known to effectively condition and soften the skin and hair.
Octadecanol is mainly used to improve the texture of formulations, to make them more appealing to the senses.
While this may not seem like an important element to a product, it is vital to ensure the product doesn’t separate or become clumpy so that the key ingredients can be distributed evenly to the skin.
The main way the stearyl alcohol does this is through acting as a thickener.
Thickeners and gelling agents are widely used throughout the cosmetic industry due to their ability to provide the products with the desired feel.
Thickeners improve the consistency, viscosity, or adhesion to the skin.
The term viscosity corresponds to the concept of “thickness”, for example, honey has a higher viscosity than water.
Thus, stearyl alcohol can be used to thicken formulas, adding body and viscosity.
Another function of stearyl alcohol is as an emulsifier.
An emulsifier is needed for products that contain both water and oil-based ingredients.
When water and oil are mixed together and vigorously shaken, a dispersion of oil droplets in water – and vice versa – is formed.
When shaking stops, however, the two types of ingredients start to separate. To address this problem, an emulsifier like stearyl alcohol can be added.
This helps the droplets remain dispersed and produces a stable smooth textured product.
As an emollient, topically applied stearyl alcohol has the ability to soften and soothe the skin.
The fatty acids that make up this ingredient create a barrier on the skin that effectively seals moisture in while keeping the air and other environmental elements out.
Therefore, stearyl alcohol can be used in creams, lotions, and ointments that are designed to improve dry, flaky skin.
Emollients help to maintain the skin’s natural barrier which is vital to the health of the skin.
Disruption of the skin’s natural barrier has been linked to conditions such as eczema, dermatitis, and psoriasis.
The emollient properties of stearyl alcohol also help to smooth and detangle hair, which is why this ingredient is used in various hair care products.
Is It Safe?
The U.S Food and Drug Administration or FDA, a governing body responsible for regulating the safety of food, drugs and cosmetic ingredients, reviewed the safety of stearyl alcohol. The FDA approved its use in cosmetic and skincare formulations as well as its use as a food additive.
The safety of stearyl alcohol has also been assessed by the Cosmetic Ingredient Review Expert Panel.
