Sodium Oleyl Sulfate is an anionic surfactant used in cosmetic and personal-care formulations for cleansing, foaming, wetting and surface-active applications. It is the sodium salt of oleyl sulfuric acid and contains an unsaturated C18 fatty alkyl chain together with a sulfate group.
The ingredient belongs to the fatty alcohol sulfate family and differs from shorter-chain sulfate surfactants such as Sodium Lauryl Sulfate because its primary hydrocarbon chain is based on oleyl alcohol.
Sodium Oleyl Sulfate can be considered for selected rinse-off cleansing formulations where an anionic surfactant with an unsaturated long-chain alkyl structure is required.
Sodium Oleyl Sulfate is an anionic fatty alcohol sulfate surfactant. Its amphiphilic structure contains a hydrophobic oleyl chain and a hydrophilic sulfate group.
The combination of these two portions allows the ingredient to interact with both water and oily materials, supporting cleansing, wetting and surfactant-system development.
Sodium Oleyl Sulfate is based on an oleyl alcohol-derived sulfate structure. For a defined oleyl chain, the molecular formula is C18H35NaO4S, with a molecular weight of approximately 370.52 g/mol.
Commercial materials can have specifications reflecting the source and composition of the fatty alcohol feedstock.
Sodium Oleyl Sulfate contains a hydrophobic C18 unsaturated alkyl chain and a hydrophilic sulfate group.
This amphiphilic structure enables it to function at interfaces and participate in surfactant processes.
Potential formulation functions include:
Sodium Oleyl Sulfate can contribute to cleansing by helping disperse oily and particulate materials in aqueous formulations.
Potential applications include:
Final cleansing performance depends on the complete formulation, surfactant concentration, pH, water quality and combination with other ingredients.
As an anionic surfactant, Sodium Oleyl Sulfate can contribute to foam generation in suitable formulations.
Potential applications include:
Foam characteristics depend on concentration, formulation composition, temperature, water quality, pH and co-surfactant selection.
Sodium Oleyl Sulfate can be evaluated in selected hair-cleansing formulations.
Potential applications include:
It may be combined with other surfactants to modify cleansing performance, foam characteristics, viscosity and sensory properties.
Sodium Oleyl Sulfate can be considered for suitable body-cleansing formulations.
Potential applications include:
Potential personal-care applications include:
Important parameters to evaluate include:
The applicable acceptance criteria should be based on the selected commercial grade.
Typical formulation-development considerations include:
Actual processing conditions should be established according to the physical form and commercial specification.
Sodium Oleyl Sulfate is an anionic fatty alcohol sulfate that can be used in selected cosmetic and personal-care cleansing systems.
For commercial procurement, buyers can evaluate:
When sourcing Sodium Oleyl Sulfate, important procurement parameters may include:
For bulk procurement, the required grade and technical specification should be confirmed before purchase.
Important parameters include:
Sodium Oleyl Sulfate is an anionic fatty alcohol sulfate surfactant used for cleansing, foaming and wetting applications in suitable cosmetic formulations.
The INCI name is Sodium Oleyl Sulfate.
It is an anionic fatty alcohol sulfate surfactant.
For a defined oleyl sulfate structure, the molecular formula is C18H35NaO4S.
The molecular weight is approximately 370.52 g/mol for the defined molecular structure.
The characteristic oleyl chain contains 18 carbon atoms.
No. The oleyl chain contains one carbon-carbon double bond, making it unsaturated.
It can be evaluated for use in suitable rinse-off hair-cleansing formulations.
Yes, it can be considered for selected body-cleansing formulations.
No. Both are C18 fatty alcohol sulfate structures, but Sodium Oleyl Sulfate has an unsaturated chain, whereas Sodium Stearyl Sulfate has a saturated chain.
No. Sodium Lauryl Sulfate has a saturated C12 chain, while Sodium Oleyl Sulfate is based on an unsaturated C18 chain.
