What is Sodium Dodecyl Sulfate?
Sodium dodecyl sulfate, also known as AS, referred to as SDS, is an anionic surfactant, alias: coco alcohol (or lauryl alcohol) sodium sulfate, K12, sles, etc.
Sodium lauryl sulfate is an anionic surfactant, which is a typical representative of sulfate surfactants, with the structural formula CH3(CH2)11OSO3Na.
Sls properties: white to slightly yellow powder with slight special gas, HLB value of 40. Non-toxic, insensitive to alkali and hard water, with decontamination, emulsifying and excellent foaming power.
A little soluble in alcohol, insoluble in chloroform and also ether, conveniently soluble in water, and has excellent compatibility with anions and also non-ions. Sodium dodecyl sulfate has good emulsifying, frothing, frothing, penetrating, sanitizing and dispersing residential or commercial properties. It has bountiful foam and also fast biodegradation, but its water solubility is substandard to that of fatty alcohol polyoxyethylene ether sulfate (AES for brief).
Salt dodecyl sulfate is extensively made use of as a foaming representative in toothpaste, soap, body laundry, shampoo, washing powder, as well as cosmetics.
At present, there is no proof that this item is carcinogenic, and high doses may undoubtedly irritate the skin. When it is utilized as a frothing agent in basic washroom items, the concentration is limited, as well as it is in line with the standards of various countries in the world, so you don’t have to stress.
