Sodium dodecyl sulfate (SDS) or sodium lauryl sulfate (SLS), sometimes written sodium laurilsulfate, is an organic compound with the formula CH 3 (CH 2) 11 OSO 3 Na and structure H 3 C−(CH 2) 11 −O−S(=O) 2 −O − Na +. It is an anionic surfactant used in many cleaning and hygiene products. This compound is the sodium salt of the 12 ...
Sodium lauryl sulfoacetate (SLSA) or lathanol is an organic compound used in many cleaning and hygiene products as an anionic surfactant. [1] Also it is used as in sodium citrate/sodium lauryl sulfoacetate/glycerol laxative products.
The related surfactant sodium lauryl sulfate or SLS (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. [1]
A common example is sodium lauryl sulfate, with the formula CH 3 (CH 2) 11 OSO 3 Na. Also common in consumer products are the sulfate esters of ethoxylated fatty alcohols such as those derived from lauryl alcohol. An example is sodium laureth sulfate, an ingredient in some cosmetics. [2]
As to whether these alternatives are "milder" or otherwise preferrable for each specific application, I don't think solid research is available. But since some consumers prefer "SLS-free" products, the market delivers. "Sodium lauryl sulfoacetate" is chemically different from Sodium lauryl sulfate though, no doubt about that.
Sodium citrate/sodium lauryl sulfoacetate/glycerol sold under the brandname Microlax and Micolette Micro enema, among others, is a small tube of liquid gel that is used to treat constipation. [ 1 ] The main active ingredients are sodium lauryl sulfoacetate (0.90% w/v ), sodium citrate (9.0% w/v ) and glycerol .
This sparked great interest in the development of synthetic detergents that biodegrade into environmentally friendly byproducts. Such interest has led to the development of the linear carbon chain compounds commonly used today, such as sodium lauryl sulfate and sodium laureth sulfate/ sodium lauryl ether sulfate (SLS/SLES). [6]
A foaming agent is a material such as a surfactant or a blowing agent that facilitates the formation of foam.A surfactant, when present in small amounts, reduces surface tension of a liquid (reduces the work needed to create the foam) or increases its colloidal stability by inhibiting coalescence of bubbles.
