Sodium Lauryl Sulfoacetate

Ingredient Spotlight:

Sodium Lauryl Sulfoacetate also commonly known as lathanol. Functioning as a primary or secondary surfactant, it comes in powder form and can vary in grains. It is a common ingredient in foaming bath products such as bath bombs, bath teas, and shower steamers. Sodium Lauryl Sulfoacetate is said to be milder on skin than ethoxylated alcohol sulfates. Biodegradable and vegetable derived, SLSa makes it an excellent ingredient.

And exactly what is a Surfactant?

Surfactants function by breaking down the interface between water and oils and/or dirt.  They also hold these oils and dirt in suspension, and so allow their removal.  They act in this way because they contain both a hydrophilic (water loving) group, such as an acid anion, (-CO2 or SO3) and a hydrophobic (water hating) group, such as an alkyl chain.  Molecules of water congregate near the former and molecules of the water-insoluble material congregate near the latter.

Soaps were the earliest surfactants and are obtained from fats known as glycerides because they are esters formed by the trihydric alcohol, propane-1,2,3-triol (glycerol), with long chain carboxylic acids (fatty acids).  The glycerides are hydrolyzed by heating with sodium hydroxide solution to form soaps, the sodium salts of the acids, and propane-1,2,3-triol.  The process is known as saponification.
