Sodium Diethylhexyl Sulfosuccinate, commonly listed under the cosmetic INCI name Diethylhexyl Sodium Sulfosuccinate, is an anionic surfactant belonging to the sulfosuccinate family. It is used in cosmetic and personal-care formulations for cleansing, wetting, dispersing, emulsifying and surfactant-related functions.
The ingredient is the sodium salt of the diester formed from 2-ethylhexyl alcohol and sulfosuccinic acid. Its amphiphilic structure contains hydrophobic 2-ethylhexyl groups and a hydrophilic sulfosuccinate portion, allowing it to reduce interfacial tension and support the dispersion and wetting of materials in formulations.
Sodium Diethylhexyl Sulfosuccinate is relevant to formulations where rapid wetting, emulsification, dispersion and cleansing properties are required. It may be considered for cleansing products, emulsions, specialty personal-care formulations and other systems requiring an effective anionic surfactant.
Sodium Diethylhexyl Sulfosuccinate is a sulfosuccinate-type anionic surfactant. The cosmetic ingredient is commonly identified as Diethylhexyl Sodium Sulfosuccinate.
The molecule contains two 2-ethylhexyl ester groups attached to a sulfosuccinate backbone, with sodium associated with the sulfonate functionality.
Sodium Diethylhexyl Sulfosuccinate has the molecular formula C20H37NaO7S and a molecular weight of approximately 444.56 g/mol for the sodium salt. The ingredient is chemically associated with the sodium salt of the diester of 2-ethylhexyl alcohol and sulfosuccinic acid.
Sodium Diethylhexyl Sulfosuccinate has an amphiphilic molecular structure containing hydrophobic 2-ethylhexyl groups and a hydrophilic sulfonated portion.
This structure enables the ingredient to participate at interfaces between different phases and reduce interfacial tension.
Potential formulation functions include:
The ingredient is documented as a surfactant with cleansing and hydrotropic functions in cosmetic ingredient assessments.
Sodium Diethylhexyl Sulfosuccinate can contribute to cleansing by assisting the interaction between water and oily or particulate materials.
Potential applications include:
The final cleansing performance depends on concentration, formulation pH, co-surfactants, electrolytes and other formulation components.
One of the important characteristics of sulfosuccinate surfactants is their ability to reduce surface and interfacial tension.
Sodium Diethylhexyl Sulfosuccinate may therefore be used where improved wetting and spreading are required.
Potential formulation benefits include:
Sodium Diethylhexyl Sulfosuccinate can assist in dispersing certain materials within formulation systems.
Potential applications include formulations containing:
The appropriate concentration should be established through formulation development.
The surfactant properties of Sodium Diethylhexyl Sulfosuccinate can support emulsification systems by reducing interfacial tension between incompatible phases.
It may be evaluated in:
Final emulsion stability depends on the complete emulsifier system, oil phase, aqueous phase, processing conditions and storage conditions.
Potential cosmetic and personal-care applications include:
The ingredient can be evaluated in suitable facial cleansing formulations where surfactant, wetting and cleansing functions are required.
Potential applications include:
The final formulation should be assessed for pH, cleansing performance, sensory characteristics, compatibility and skin tolerance.
Sodium Diethylhexyl Sulfosuccinate may be incorporated into suitable body-cleansing formulations.
Potential applications include:
Its surfactant and wetting characteristics make it suitable for evaluation in certain makeup-removing and cleansing systems.
It can support the dispersion and removal of cosmetic residues during rinsing.
The complete formulation should be evaluated for cleansing efficiency, sensory properties and compatibility with the intended application.
Important parameters to evaluate include:
The exact acceptance criteria should be based on the selected commercial grade and its approved specification.
Typical formulation-development steps include:
Because sulfosuccinate structures contain ester linkages, formulation stability should be evaluated carefully, particularly under strongly acidic or otherwise hydrolytically challenging conditions.
Sodium Diethylhexyl Sulfosuccinate is a specialty anionic surfactant suitable for cosmetic formulations requiring cleansing, wetting, dispersion and emulsification properties.
For commercial procurement, buyers can evaluate:
When sourcing Sodium Diethylhexyl Sulfosuccinate, important procurement parameters include:
For bulk procurement, the required grade and specification should be confirmed before purchase.
Important parameters include:
Sodium Diethylhexyl Sulfosuccinate is an anionic sulfosuccinate surfactant commonly identified by the INCI name Diethylhexyl Sodium Sulfosuccinate.
The INCI name is Diethylhexyl Sodium Sulfosuccinate.
The CAS number is 577-11-7.
The molecular formula is C20H37NaO7S.
The molecular weight is approximately 444.56 g/mol.
It is an anionic surfactant.
It is used for surfactant and cleansing functions, with wetting, dispersing, emulsifying, foaming and hydrotropic properties also relevant depending on the formulation.
The names are sometimes used inconsistently in commercial literature, so the CAS number and INCI identity should be checked carefully. For the cosmetic INCI Diethylhexyl Sodium Sulfosuccinate, use CAS 577-11-7.
No. They are different sulfonated surfactants with different molecular structures and CAS numbers.
Yes. It is documented as a cosmetic surfactant ingredient and can be used in appropriate cosmetic formulations.
