Steareth-2 is a surfactant that is made from stearyl alcohol and ethylene oxide.
Steareth-2 is a substance that is not allowed in natural or BIO certified cosmetics.
Steareth-2 is a synthetic irritant, more precisely an ethoxylated compound composed of polyethylene glycol polymer and stearyl alcohol.
Steareth-2 occurs in the form of a light waxy substance, soluble in alcohol, but not in water.
In the cosmetics industry, Steareth-2 functions as an emulsifier, surfactant and surface-active agent, in addition to reducing surface tension and improving the mutual bonds of ingredients in the product.
Steareth-2 is a surfactant that is made from stearyl alcohol and ethylene oxide.
Steareth-2 belongs to the so-called ethoxylated compounds, which are prepared by polymerization of ethylene oxide and are available in a wide range of molecular weights.
During the reaction, the by-product 1,4-dioxane is formed.
These two substances (ethylene oxide, 1,4-dioxane), which are known to have carcinogenic effects, are common contaminants of ethoxylated compounds.
If ethoxylated compounds are used as a cosmetic raw material, the concentration of these contaminants must be reduced to the “permissible level”.
Ethoxylated compounds are not accepted in certified natural and BIO cosmetics.
If an ingredient such as this is absent from certain skin care formulations, the solution would separate (sort of like what you see with certain oil-based salad dressings).
Steareth-2 is often combined with other steareth ingredients, such as steareth-21, since this combination provides an elevated sensory experience.
In 2012, the independent Cosmetic Ingredient Review panel ruled that steareth-2 is safe as used in cosmetics in amounts up to 10%.
There have been concerns about the safety of steareth ingredients because toxic 1,4-dioxane, a by-product of ethoxylation, can be produced; however, this is eliminated through purification processes.
Steareth-2 is polyethylene glycol ethers of stearic acid.
Steareth-2’s ingredients are prepared by interacting with the chemical intermediate gas ethylene oxide with stearyl alcohol, a process which forms an entirely new stable compound.

Steareth ingredients are prepared by interacting with the chemical intermediate gas ethylene oxide with stearyl alcohol, a process which forms an entirely new stable compound.
The number that comes after indicates the average number of ethylene oxide units used in the preparation.
The Steareth ingredients (Steareth-2, Steareth-4, Steareth-6, Steareth-7, Steareth-10, Steareth-11, Steareth-13, Steareth-15, Steareth-20) are polyethylene glycol ethers of stearci acid.
In cosmetics and personal care products, Steareth ingredients are used in the formulation of personal cleanliness products and deodorants, as well as suntan, fragrance, skin, eye and hair products.
The Steareths are prepared by reacting ethylene oxide with stearyl alcohol where the numerical value in the name corresponds to the average number of units of ethylene oxide.
For example, Steareth-2 is prepared using an average of 2 units of ethylene oxide reacted with stearyl alcohol.

In cosmetics and personal care products, Steareth-2 primarily functions as an emulsifier to help water and oil-based ingredients stay together so that an emulsion is formed.
Steareth-2 is used in the formulation of personal cleanliness products and deodorants, as well as suntan, fragrance, skin, eye and hair products.
Steareth-2 is a waxy solid material that helps oil and water to mix together, aka emulsifier.
Steareth-2 is derived from the fatty alcohol, stearyl alcohol by ethoxylating it and thus making the molecule a little water-soluble.
Steareth-2 has only a small amount of ethoxylation and thus the molecule is still largely oil soluble.
Steareth-2 is often mixed with more water-soluble emulsifiers (such as Steareth-20) to create stable emulsion systems.
Steareth-2 is a PEG ether of stearyl alcohol Steareth-2 uses and applications include: Intermediate in the manufacturing of high-foaming surfactants; emulsifier, detergent, dispersant, wetting agent for pulppaper, textiles, paints, adhesives, corrosion inhibitors, petrol oils; surfactant, emulsifier in topical pharmaceuticals, cosmetics; thickener; emollient; solubilizer, coupling agent; stabilizer
