Sodium Lauryl Sulfoacetate is a synthetic/plant-origin cosmetic surfactant used primarily for cleansing and foaming applications. It is an anionic surfactant with the INCI name Sodium Lauryl Sulfoacetate and CAS Number 1847-58-1.
The ingredient is the sodium salt of the dodecyl ester of sulfoacetic acid. Its molecular structure combines a C12 lauryl chain with a sulfoacetate group, providing surface-active properties useful in rinse-off personal-care formulations.
Sodium Lauryl Sulfoacetate is used in cosmetic formulations including cleansing products, shampoos, bath products, facial cleansers, body washes, shower products and other formulations where cleansing and foam generation are required.
Sodium Lauryl Sulfoacetate is an anionic surfactant that functions primarily as a cleansing and foaming ingredient.
Its structure contains a long-chain lauryl group and a sulfonate-containing hydrophilic portion. This amphiphilic structure enables the ingredient to interact with water and oily materials and contribute to the removal of impurities during cleansing.
The ingredient is different from Sodium Lauryl Sulfate (SLS). Although the names are similar, Sodium Lauryl Sulfoacetate has a sulfoacetate ester structure, whereas Sodium Lauryl Sulfate is a sulfate ester.
Sodium Lauryl Sulfoacetate has the molecular formula C14H27NaO5S and molecular weight of approximately 330.42 g/mol.
Its systematic chemical identity is sodium 2-dodecoxy-2-oxoethanesulfonate.
These chemical identifiers are consistent with the current PubChem record.
Sodium Lauryl Sulfoacetate is primarily used for cleansing.
Its surface-active structure can help facilitate the interaction between water, oils and particulate materials, supporting their removal during rinsing.
Potential formulation functions include:
The recognized cosmetic functions include cleansing, foaming, and surfactant-cleansing.
Sodium Lauryl Sulfoacetate can contribute to foam formation in rinse-off formulations.
It can be considered for products where a visible and stable foam profile is desirable.
Potential applications include:
Foam performance depends on the overall formulation, surfactant concentration, co-surfactants, pH, electrolytes, water quality and processing conditions.
Sodium Lauryl Sulfoacetate can be evaluated as part of a shampoo surfactant system.
Potential applications include:
During formulation, the complete surfactant system should be evaluated for cleansing performance, foam, viscosity, pH, hair feel and compatibility with conditioning ingredients.
Sodium Lauryl Sulfoacetate can be incorporated into suitable facial cleansing formulations.
Potential applications include:
The final formulation should be evaluated for cleansing performance, sensory properties, pH, foam characteristics and compatibility with other ingredients.
Sodium Lauryl Sulfoacetate can be used in suitable body-cleansing formulations.
Applications may include:
It can be combined with other surfactants, humectants, conditioning ingredients and viscosity modifiers.
Sodium Lauryl Sulfoacetate has applications across several personal-care categories.
Potential applications include:
Sodium Lauryl Sulfoacetate is structurally different from sulfate surfactants.
The sulfoacetate group provides the ionic portion of the molecule, while the lauryl chain contributes the hydrophobic portion.
This combination produces an amphiphilic molecule suitable for surface-active applications.
It should not be described as chemically identical to Sodium Lauryl Sulfate simply because both contain a lauryl chain and are anionic surfactants.
Important parameters to evaluate during formulation development include:
Commercial Sodium Lauryl Sulfoacetate grades can contain additional inorganic components. Therefore, the exact specification should be based on the selected commercial grade rather than assuming a universal purity value. PubChem records a commercial powder example containing approximately 64–85% active ingredient, with sodium sulfate and sodium chloride making up the remainder.
Typical formulation-development considerations include:
Actual processing conditions should be established according to the physical form and commercial grade being used.
Sodium Lauryl Sulfoacetate is a specialty anionic surfactant used in cosmetic and personal-care cleansing formulations.
For commercial procurement, buyers can evaluate:
When sourcing Sodium Lauryl Sulfoacetate, important procurement parameters may include:
For bulk procurement, the required grade and technical specification should be confirmed before purchase.
