The difference between SDS and SLS
Sodium dodecyl sulfate (short for SDS), also can be as sodium lauryl sulfate (short for SLS), its molecylar formula is CH3 (CH2) 10CH2OSONa, the molecular weight is 288.38.
Sodium dodecyl sulfonate also short for SDS, its molecylar formula is CH3(CH2)10CH2SONa, the molecular weight is 272.38.
These two substances are anionic surfactants, are solid, in which twelve sodium alkyl sulfate is commonly used biochemical and immune experiments.
Reagently, and twelve sodium alkyl sulfonic acid because of its manufacturing and performance on some of the shortcomings, almost no medical, biological Laboratory use. Our country's "chemical reagent domestic and international standards", as well as foreign famous companies such as Sigma, Aldrich and Fluka and other products are not included in the directory.
The common mistake is to say that this is the sodium dodecyl sulfate, said to be the sodium dodecyl sulfonate.
Sodium dodecyl sulfonate has good decontamination ability, and is the main ingredient in the primary decontamination detergent and washing powder.
Sodium dodecyl sulfate also known as K12, foaming better detergency than sodium dodecyl benzene sulfonate weak, commonly used in toothpaste, shampoo and other products.
Sodium dodecyl sulfate and sodium dodecyl sulfonate are all solid, surface active agent. As a result of the use of double - layer plastic bags, not only convenient transportation and use, but also save the cost of packaging. According to different levels, the market has 50%, 60%, 40%, 70% and so on the different levels of sodium sulfonate. The price is also different. We should pay attention to identify.
