Steareth-20 as surfactant is used for skin and hair-cleaning purposes and as emulsifier and solubilizing agent in cosmetics and Hair Colorants. 

Steareth-20 helps to keep the product stable over time and is also a “wash-out” component in Developers and Hair Colorants, means it helps to remove all residues after a Hair Color application.

Steareth-20 is a synthetic ingredient that functions as a cleansing agent, a surfactant, and an emulsifier to improve the texture and feel of formulations.

Steareth 20 is used as cleansing agent, a surfactant and an emulsifier, like many other PEG and other oil derived substances. 

According to the Cosmetics Database Steareth 20 is found most often in eye creams, anti-aging skin care products and moisturizers.

Steareth-20 is added to cosmetics and skincare products because it functions as a cleansing agent, a surfactant, and an emulsifier. 

These abilities help to improve the texture and feel of skincare products. 

Derived from the benign fatty ingredient stearyl alcohol, Steareth-20 functions primarily as a surfactant but is also used to make products more stable, especially if they contain active ingredients in an emulsion.

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 stearic acid. 

Steareths are waxy compounds. 

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.

Coemulsifier

Steareth-20 is a synthetic ingredient that functions as a cleansing agent, a surfactant, and an emulsifier in a variety of cosmetics and skincare products.

The group of steareth ingredients are synthetic compounds that are created through a process known as ethoxylation, a chemical reaction in which ethylene oxide is added to a substrate. 

With steareth-20, the substrate is stearyl alcohol, a fatty alcohol that is derived from stearic acid. 

The number associated with the steareth-20 indicates the average number of repeating ethylene oxide units in the molecule. 

The steareth ingredients are waxy solids that can be used in cosmetics at concentrations of up to 25 percent.

Steareth-20  is a Surfactant

Steareth-20 is an ingredient which lowers the surface tension between two substances, such as two liquids or a liquid and a solid. 

In skincare products, Steareth-20 works to degrease and emulsify oils and fats and suspend dirt, allowing them to be washed away. 

This is possible because while one end of Steareth-20 is attracted to water, the other end is attracted to oil. 

Thus, Steareth-20 attracts the oil, dirt, and other impurities that have accumulated on your skin during the day and wash them away. 

Due to these properties, steareth-20 can be found in many different cleansers and body washes.

Steareth-20 is an Emulsifier

Steareth-20 also functions as an emulsifier. 

An emulsifier is needed for products that contain both water and oil-based ingredients. 

When water and oil are mixed together the two ingredients often separate or split. 

To address this problem, an emulsifier like steareth-20 can be added which helps to produce a stable product.

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-20 is prepared using an average of 20 units of ethylene oxide reacted with stearyl alcohol.

Steareth-20 is an emulsifier for cosmetic and pharmaceutical oil-in-water emulsions. 

This emulsifier is particularly suitable for sprays and antiperspirants/deodorant roll-ons in combination with Steareth-2.

Steareth-20 is added to cosmetics and personal care products because it functions as a cleansing agent, a surfactant, and an emulsifier.

In skin care products, Steareth-20 works to degrease and emulsify oils and fats and suspend soil, allowing them to be washed away.

Steareth-20 (PEG-20 Stearyl Ether) is a type of Polyethylene glycol (ether) made from Stearyl alcohol used for cleansing, slight conditioning, as well as keeping a product from separating into its oil and water components. 

Steareth-20 is a whiteish waxy solid that’s water dispersible. 

Steareth-20 is found in a ton of products, such as moisturizers, hair products, facial cleansers, makeup, and hair grooming products
