Hydrophilic emulsifie<r; forms emulsions with good temperature resistance
Beheneth-20 is a polyethylene glycol ether of Behenyl Alcohol (q.v.).
Beheneth-20 is used as an emulsifier in cosmetic products.
Since the carbon number of the alkyl group of Beheneth-20 is larger than that of stearyl ethers or cetyl ethers, Beheneth-20 can be used to produce cosmetics with excellent emulsifying power, moisture retention and spreadability.
Emulsifiers, effects of Peg Beheneth -5, -10, -20, -25 are derivatives of polyethylene glycol and non -drying runhenyl alcohol, which act as emulsifiers and surface active substances in skin care products.
Can be synthetic or derived from plants.
Is a derivative of polyethylene glycol and non-drying behenyl alcohol.
Beheneth-20 can be synthetic or derived from plants.
This ingredient functions as an emulsifier to help the water & oil ingredients blend together in the formula.
Or at a higher concentration Beheneth-20 can act as a surfactant so that water can mix with excess oil & dirt for easy cleaning.
"Beheneth-" refers to a PEG (polyethylene glycol) ether of behenyl alcohol.
The number after "Beheneth-" indicates the average number of molecular units -CH2-CH2-O-.
Surfactants are so-called washing-active substances and are of great importance in cosmetics for cleaning the skin and hair.
Surfactants (from the Latin "tensus" = tense) are substances that, thanks to their molecular structure, are able to reduce the surface tension of a liquid.
In this way, two liquids that are actually not miscible, such as oil and water, can be finely mixed.
Because of their properties, surfactants are used in many different ways in cosmetics: They can clean, create foam, and also act as emulsifiers and mix substances with one another.
In shampoos, shower gels and soaps, for example, surfactants are used to wash away fat and dirt particles from the body with water.
Surfactants are also used in toothpaste.
The surfactants used in cosmetic products are mainly produced synthetically on the basis of plant-based raw materials.
Surfactants are often used in combination in order to meet all desired requirements - such as dirt removal and foam formation combined with good skin compatibility - in the best possible way.
A skilful combination of a tenside with unfavorable skin compatibility, but very good dirt-dissolving properties, and a very mild, skin-friendly tenside - viewed on Beheneth-20 own - results in a product with good cleaning properties and equally good skin compatibility.
Polyethylene glycols (INCI: PEG-...) are polycondensation products of ethylene glycol or polymerisation products of ethylene oxide.
The number attached to the name indicates the average number of ethylene oxide units in the substance.
The consistency of the PEG derivatives becomes increasingly firm as the degree of polymerization increases.
PEGs with an average molar mass of up to 600 g/mol are liquid, up to 1000 g/mol are waxy and from 4000 g/mol are solid, waxy substances.
By mixing solid and liquid components, products with a creamy consistency are obtained, which are used as water-free and water-washable bases.
With increasing molar mass, the water solubility and hygroscopicity (moisture absorption capacity) of the polyethylene glycols decrease.
Emulsifiers are often used as auxiliary substances in cosmetics.
They make Beheneth-20 possible to bring components that are actually not miscible with each other, such as oil and water, into a permanently stable emulsion.
In cosmetic products, both aqueous and oily care and active ingredients can be used in a single product.
Emulsifiers are able to do this because their molecules consist of a fat-loving (lipophilic) and a water-loving (hydrophilic) part.
This allows them to reduce the interfacial tension that actually exists between two incompatible substances such as fat and water.
Emulsifiers are used in particular for creams, lotions and cleaning agents.
In the meantime, however, emulsifiers are much more than just auxiliary substances that keep an emulsion stable.
