Steareth-50 is an oil-in-water emulsifier that is used for the production of ointments, creams, liquid emulsions, gels and other cosmetic formulations.
Steareth-50 is supplied in the form of free-flowing, non-dusting micro-granules, and is an efficient protective colloid that can increase the stability of dispersed systems.
This research grade Steareth-50 is intended for use in R&D only.

Steareth-50 is a nonionic surfactant prepared from cetyl and stearyl alcohol and 50 moles of ethylene oxide.
Steareth-50 is used in cosmetics as surfactant and emulsifier: HLB (17.7).
Steareth-50 makes it possible to create oil-in-water emulsions.
Steareth-50 is controversial because of its manufacturing process and low biodegradability.
"Steareth-50" refers to a PEG (polyethylene glycol-) ether of cetearyl alcohol.
The number behind "Steareth-50" refers to the average number of molecular units -CH2-CH2-O-.
Steareth-50 are poly condensation products of ethylene glycol, or polymerisation products of ethylene oxide.
The number added to the name refers to the mean number of ethylene oxide units in the substance.
The consistency of the Steareth-50 is increasingly solid with a growing degree of polymerisation.
Steareth-50 with a mean molar mass of up to 600 g/mol are liquid, up to 1,000 g/mol wax-like and from 4,000 g/mol solid wax-like substances.
By mixing solid and liquid components, products of a creamy consistency are obtained which are used as water-free and water rinse-off bases.
With growing molar mass water solubility and hygroscopicity (ability to absorb moisture) of the polyethylene glycols decrease.
Surfactants are so-called detergent substances and have a major significance in cosmetics for the cleansing of the skin and hair.
Surfactants are substances which, based on their molecular structure, are able to reduce the surface tension of a liquid.
In this way Steareth-50 is possible that two actually not mixable substances, such as oil and water, can be finely mixed.
Because of their properties, Steareth-50 have manifold uses in cosmetics: they can cleanse, produce foam and act as emulsifiers and mix substances with one another.
In shampoos, shower gels and soaps, surfactants are, for instance, used to wash fat and soil particles with water off from the body.
Steareth-50 are also used in toothpaste.
Here they promote during tooth cleaning the rapid and full dissolution and distribution of the paste in the mouth.
Steareth-50 used in cosmetic products are primarily produced synthetically on the basis of vegetable raw materials.
Steareth-50 are often used in combination to equally meet all desired requirements – like dissolution of soil and formation of foam in combination with a good skin tolerance – in the best possible manner.
Through a skilled combination of a Steareth-50 – viewed on its own – with unfavourable skin tolerance but a very good soil removal property with a very mild, skin protecting surfactant altogether a product with good cleansing properties and the same good skin tolerances is obtained.
Steareth-50 are often used in cosmetics as excipients.
They allow actually unmixable components like oil and water to be brought in a permanently stable emulsion.
In this way both aqueous and oily care and active ingredients can be used in one and the same product in cosmetics.
Steareth-50 are able to do that since their molecules consist of a lipophilic and a hydrophilic part.
In this way they can reduce the interfacial tension which actually exists between two incompatible substances like fat and water.
Steareth-50 are, more particularly, used for creams, lotions and cleansing agents.
At present emulsifiers are, however, more than only excipients which keep an emulsion stable.
Fatty acid esters on the basis of sugar, lecithin or glycerin monodistearate contribute, for instance, to improving the moisture balance of the skin and are, therefore, also considered as cosmetic active ingredients.
Steareth-50 is a fatty alcohol with high saturation.
Steareth-50 is in the form of white particles / powder, odorless, soluble in water and alcohol to form a colloidal solution.
Steareth-50 is suitable for emulsion cosmetics, textiles, detergents.
