WHAT IS CETEARETH 50 USED FOR?
Ceteareth 50 is a versatile ingredient that gives cosmetics a silky texture and enhances their performance.
Ceteareth 50 is a surfactant that lowers the surface tension of products.
This allows them to spread smoothly and evenly on the skin and hair.
Ceteareth 50 readily mixes oil and water-based ingredients to form stable emulsions.
Ceteareth 50 is commonly found in moisturizers, creams, sunscreens, and shampoos.

In hair care, Ceteareth 50 makes the strands soft and reduces frizz.
ORIGIN of CETEARETH 50:
Ceteareth 50 is made by combining cetyl alcohol or stearyl alcohol with 50 units of ethylene oxide.
This process is called ethoxylation.
Ceteareth 50 creates a compound that is both water and oil soluble.

WHAT CETEARETH 50 IS USED FOR AND WHERE
***Cosmetics
*Surfactant - Emulsifying agent.
Emulsions are thermodynamically unstable.
Emulsifiers have the property to reduce the oil/water or water/oil interfacial tension, improve emulsion stability and also directly influence the stability, sensory properties and surface tension of sunscreens by modulating their filmometric performance.
*Surfactant - Cleansing agent.
Cosmetic products used to cleanse the skin utilise the surface-active action that produces a lowering of the surface tension of the stratum corneum, facilitating the removal of dirt and impurities.
FUNCTIONS (INCI) of CETEARETH 50:
*Cleansing :
Ceteareth 50 helps to keep a clean surface
*Emulsifying :
Ceteareth 50 promotes the formation of intimate mixtures between immiscible liquids by modifying the interfacial tension (water and oil)
*Surfactant :
Ceteareth 50 reduces the surface tension of cosmetics and contributes to the even distribution of the product when it is used
BACKGROUND INFORMATION ON USE IN COSMETICS
Polyethylene glycols (INCI: PEG-...) 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 PEG derivatives is increasingly solid with a growing degree of polymerisation.
PEGs 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 it is possible that two actually not mixable substances, such as oil and water, can be finely mixed.
Because of their properties, surfactants 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, Ceteareth 50 is used to wash fat and soil particles with water off from the body.
Surfactants are also used in toothpaste.
Here they promote during tooth cleaning the rapid and full dissolution and distribution of the paste in the mouth.
The surfactants used in cosmetic products are primarily produced synthetically on the basis of vegetable raw materials.
Surfactants 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 surfactant – 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.
Emulsifiers 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.
Emulsifiers 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.
Emulsifiers 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.
