STEARETH-2

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. They 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.
When added to cosmetics and personal care products, the Steareth ingredients reduce the interactive forces between molecules of other liquids so that an emulsion is formed. If an ingredient such as a Steareth is not added to some personal care products, the ingredients in the product would separate like some salad dressings.
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.

Chemical and physical properties of Steareth 2
Steareths-2, -10 and -20 are waxy solids. They are soluble in ethanol and other lower alcohols and insoluble in mineral oil and coal tar hydrocarbon.
Solubility in water varies and increases with increasing ethylene oxide These compounds have an average molecular weight range of 358 for Steareth 2 to 1150 for Steareth 20. In cosmetic grade steareth (-2, -10, -20),
about 95% of the alkyl chain is stearyl (C18), with smaller amounts consistent in cetyl (Cq6) and "other alkyl groups" (not specified)

When added to cosmetics and personal care products, Steareth ingredients reduce the interactive forces between molecules of other liquids so that an emulsion is formed. If an ingredient such as a Steareth is not added to some personal care products, the ingredients in the product would separate like some salad dressings.

Scientific Facts:
Steareth is prepared by reacting ethylene oxide with stearyl alcohol where the numerical value in the name is the average number of ethylene oxide units. For example, Steareth 2 is prepared using an average of 2 units of ethylene oxide reacted with stearyl alcohol. The ingredients of Steareth are a series of polyoxyethylene stearyl ethers. In cosmetics and personal care products, Steareths work primarily as surfactants - emulsifiers. They can also be used as wetting agents, solubilizers and nonionic surfactants

Steareth-2 is Polyoxyethylene fatty ether derived from stearyl alcohols designed to emulsify and produce stable dispersions of cosmetic materials

Steareth-2 is a water-in-oil emulsifier.
Steareth-2 is also used in antiperspirants, depilatories, cold waves, bleaches and dyes.

Steareth-2 is a waxy solid material that helps oil and water to mix together (emulsifier).
Steareth-2 is derived from the fatty alcohol, stearyl alcohol by ethoxylating it and thus making the molecule a little water-soluble.
This version 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 Ethoxylated stearyl alcohol. Steareth-2 is Nonionic emulsifier for various O/ W skincare emulsions, especially suitable for O/ W antiperspirant roll-ons.
Steareth-2 is an emulsifier for the formulation of cosmetic O/W and W/O emulsions suitable for the preparation of antiperspirants.
