Sodium lauryl sulfoacetate

Sodium Lauryl Sulfoacetate (SLSa) is a commonly used ingredient in a variety of personal care and cleaning products. It is a surfactant, which means it helps to create lather and remove dirt and oils. Despite its similar name, it is not to be confused with Sodium Lauryl Sulfate (SLS), a related but different compound.

Chemical Structure and Properties

Sodium Lauryl Sulfoacetate is a white powder with the chemical formula C14H27NaO5S. It is a sodium salt of a partially sulfated fatty acid. It is soluble in water and can produce a rich, stable lather. It is often used in products that require a lot of foam, such as bubble baths and shampoos.

Uses

Sodium Lauryl Sulfoacetate is used in a wide range of products, including shampoo, toothpaste, bubble bath, and laundry detergent. It is valued for its ability to produce a large amount of foam and its mildness compared to other surfactants. It is also used in some food products as an emulsifier.

Safety and Environmental Impact

Sodium Lauryl Sulfoacetate is considered to be a safe ingredient for use in cosmetics and personal care products by the Cosmetic Ingredient Review (CIR) Expert Panel. It is also biodegradable, meaning it can be broken down by bacteria and other organisms in the environment.

However, like all surfactants, it can cause irritation if it comes into contact with the eyes or if it is ingested. It is recommended to rinse thoroughly with water in case of eye contact and to seek medical attention if ingested.
