LAURETH-3 is a Lauryl Alcohol 3 ethoxylate that on account of LAURETH-3 viscosity-increasing properties, is used as a thickener in cosmetic surfactant preparations such as shampoos, shower preparations and foam baths.
LAURETH-3 is a clear to light turbid product, with a standard odor and appearance.
LAURETH-3 is a surfactant and a thickner.
As surfactant LAURETH-3 helps to reduce surface tension of substances to be mixed or emulsified.
In cosmetics LAURETH-3 helps water to be mixed with oil, sebum and dirt so that they can be easily rinsed away.
Moreover as thickener LAURETH-3 helps to adjust the thickness of our products.
Ethoxylated alcohol formulas such as Lauryl Alcohol are classified as surfactants, which means they reduce surface tension in a liquid, or between a liquid and a solid.
As with all types of ethoxylated alcohol, Lauryl Alcohol Ethoxylate is a nonionic compound — LAURETH-3 has no electrical charge on the hydrophilic end and generally takes the form of a thick liquid that is often sticky to the touch.
The ethoxylation process also tends to increase the water solubility of the material.
Products that typically contain Lauryl Alcohol Ethoxylate include cosmetics, laundry detergents, surface cleaners and personal care products, to name a few.
LAURETH-3 can be stored for at least to 2 years in original sealed containers at room temperature under the recommended conditions.
Protect from exposure to cold during transport and storage.
The properties of LAURETH-3 are reversibly altered by exposure to cold.
LAURETH-3 becomes turbid, thickens or freezes through exposure to cold, thaw slowly at room temperature and afterwards stir briefly.
LAURETH-3 is a PEG ether of lauryl alcohol.
LAURETH-3 uses and applications include: Surfactant, emulsifier, foaming agent, superfatting agent) for cosmetics.
Solubilizer for solvents.
Base for production of sulfates.
Raw material for dishwashing, cleansing agents and cold cleaners.
Emulsion polymerization.
In coning and textile spin finishes.
Thickener, emulsifier, solubilizer for pharmaceuticals.
Functions of LAURETH-3:
Solvents,
Surfactant,
Emulsifier,
Raw Material.
Uses of LAURETH-3:
The solubility of the LAURETH-3 alcohol ethoxylates is determined by the chain length of the water soluble ether chain.
Accordingly the solubility increases with increased degree of ethoxylation.
The lower ethoxylates (2–4 moles EO) are only sparingly soluble in water as these molecules are dominated by the hydrophobic alcohol part.
They are soluble in non-polar organic solvents and can be applied therefore as emulsifiers.
The higher ethoxylates are readily soluble in water and they are used predominantly for cleaning applications.
Gel Formation with Water:
Mixtures of water and alcohol ethoxylates like the LAURETH-3 surfactant can cover a wide range of viscosities from free flowing liquids to solid gels depending on the amount of water added.
The gel phases typically occur at medium concentrations and can have significant stability when water is added.
When diluting Lauryl Alcohol ethoxylate products to lower concentrations LAURETH-3 is recommendable to avoid these gel phases during processing.
This can be achieved by adding the nonionic surfactant to water, to use warm water and to stir well.
Additional solvents, for example alcohols, but also salts and other electrolytes can help to suppress gel formation.
LAURETH-3 is a laureth-3 polymer used as a nonionic emulsifier for the preparations of oil and cream baths.
LAURETH-3 is a clear to light turbid liquid.
LAURETH-3 has multiple industrial uses and applications including:
Use Lauryl Alcohol Ethoxylate as a wetting agent to reduce the surface tension in liquids, and as an emulsifier in paints and coatings to promote dispersion.
Personal Care:
Lauryl Alcohol Ethoxylate works extremely well as a foaming agent in personal care products such as shampoos and bath gels.
Soaps and Detergents:
Lauryl Alcohol serves as a reliable wetting agent in a wide range of industrial and household cleaning products including detergents, laundry pre-spotters and hard surface cleaners.
Surfactants and Esters:
You can use Lauryl Alcohol as a surfactant intermediate — LAURETH-3 can also be sulfonated to make SLES (Sodium Lauryl Ether Sulfate), an anionic surfactant and detergent used in the manufacturing of many personal care products.
Textiles:
Use Lauryl Alcohol Ethoxylate as a wetting agent in textile and leather processing applications to reduce surface tension.
Applications of LAURETH-3:
Lauryl Alcohol ethoxylate grades (C12-14 fatty alcohol ethoxylates) are nonionic surfactants.
They are alkyl polyethylene glycol ethers made from saturated native fatty alcohol.
Thus their C-chain is linear and even numbered. They are available with low and medium EO-degree.
The available grades are liquid.
Lauryl Alcohol ethoxylate grades are providing wetting and emulsification properties with a good soil removal property.
LAURETH-3 of the Lauryl Alcohol ethoxylates series are fatty alcohol polyethylene glycol ethers and belong to the class of nonionic surfactants.
LAURETH-3 is prepared from a natural-based C12-C14 fatty alcohol and thus are excellent candidates for use in consumer products such as green and environmental friendly cleaners.
The individual grades in the Lauryl Alcohol ethoxylate series a broad spectrum of properties.
In general, LAURETH-3 is characterized by the following properties:
High surface activity and detergency,
Synergistic effects with other surfactants,
Good hard water stability,
Chemical stability over a wide pH range,
Produced from a natural-based, renewable raw material,
Low environmental impact as a result of rapid and complete biodegradation.
These favourable and widespread properties have opened up numerous fields of application for LAURETH-3 as well.
LAURETH-3 is effective in detergents & cleaners and also in personal care products or in technical applications.
LAURETH-3 is based on a primary linear C12–C14 fatty alcohol.
The alcohol is obtained from oleo oils, e.g. palm kernel oil, by transesterification and hydrogenation reaction.
Storage and Transportation of LAURETH-3:
In the original sealed containers the product can be stored for at least one year, protected from moisture at below 40°C.
During longer storage turbidities may occur which can be remedied by simultaneously heating the product to 40°C and stirring.
