Product name:Sodium Laureth
Sulfate(SLEs) CAS:*******3 Molecular
formula:C*2H*5NaO4S Molecular weight:**8.*8 Description:Sodium laureth sulfate,
or sodium lauryl ether sulfate (SLES), is an anionic detergent and
surfactant found in many personal care products (soaps, shampoos,
toothpaste etc.). SLES is an inexpensive and very effective foaming
agent. SLES, SLS, ALS and sodium pareth sulfate are surfactants
that are used in many cosmetic products for their cleansing and
emulsifying properties. They behave similarly to soap.
Its chemical formula is
CH3(CH2)*0CH2(OCH2CH2)nOSO3Na. Sometimes the number represented by
n is specified in the name, for example laureth*2 sulfate. The
product is heterogeneous in the number of ethoxyl groups, where n
is the mean. It is common for commercial products for n= 3. SLES is
prepared by ethoxylation of dodecyl alcohol. The resulting
ethoxylate is converted to a half ester of sulfuric acid, which is
neutralized by conversion to the sodium salt. The related
surfactant sodium lauryl sulfate (also known as sodium dodecyl
sulfate or SDS) is produced similarly, but without the ethoxylation
step. SLS and ammonium lauryl sulfate (ALS) are commonly used
alternatives to SLES in consumer products.
