LAURETH-2 is a surfactant and a thickner.
As surfactant LAURETH-2 helps to reduce surface tension of substances to be mixed or emulsified.
In cosmetics LAURETH-2 helps water to be mixed with oil, sebum and dirt so that they can be easily rinsed away.
Moreover as thickener LAURETH-2 helps to adjust the thickness of our products.
LAURETH-2 is a PEG ether of lauryl alcohol.
LAURETH-2 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.
In general, LAURETH-2 group is characterized by the following properties:
LAURETH-2 has high surface activity and detergency,
LAURETH-2 shows synergistic effects with other surfactants,
LAURETH-2 has good hard water stability,
LAURETH-2 has chemical stability over a wide pH range,
LAURETH-2 is produced from a natural-based, renewable raw material,
LAURETH-2 has low environmental impact as a result of rapid and complete biodegradation.
Uses of LAURETH-2:
LAURETH-2 (C12-14 fatty alcohol ethoxylates) is nonionic surfactant.
LAURETH-2 is alkyl polyethylene glycol ether made from saturated native fatty alcohol.
Thus C-chain of LAURETH-2 is linear and even numbered.
LAURETH-2 provides good wetting and emulsification properties with a good soil removal property.
LAURETH-2 has multiple industrial uses and applications including:
LAURETH-2 is used as a wetting agent to reduce the surface tension in liquids, and as an emulsifier in paints and coatings to promote dispersion.
Personal Care:
LAURETH-2 works extremely well as a foam adjusting agent in personal care products such as shampoos and bath gels.
Soaps and Detergents:
LAURETH-2 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 LAURETH-2 as a surfactant intermediate — LAURETH-2 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:
LAURETH-2 is used as a wetting agent in textile and leather processing applications to reduce surface tension.
LAURETH-2 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-2 are reversibly altered by exposure to cold.
LAURETH-2 becomes turbid, thickens or freezes through exposure to cold, thaw slowly at room temperature and afterwards stir briefly.
