Sodium Oleoyl Isethionate is an oleic-acid-derived isethionate surfactant used in cosmetic and personal-care formulations. It is the sodium salt of the oleic acid ester of isethionic acid and is primarily used as a cleansing and hair-conditioning ingredient.
Its amphiphilic structure contains a hydrophobic oleoyl portion and a hydrophilic sulfonate-containing isethionate portion. This structure gives the ingredient surface-active properties that support cleansing and foam formation.
Sodium Oleoyl Isethionate can be considered for facial cleansers, body cleansers, hair-care products, cleansing bars, foaming formulations and other personal-care applications.
Sodium Oleoyl Isethionate is the sodium salt of the oleic acid ester of isethionic acid. The oleoyl component is associated with oleic acid, while the isethionate portion contains the 2-hydroxyethanesulfonic-acid-derived structure.
It belongs to the family of isethionate surfactants.
Key characteristics include:
Sodium Oleoyl Isethionate is chemically described as the sodium salt of the oleic acid ester of isethionic acid. The CIR safety assessment specifically identifies CAS 142-15-4 and classifies the ingredient as a hair-conditioning agent and cleansing surfactant.
Important identification information includes:
The molecular formula reported for Sodium Oleoyl Isethionate is C20H38O5S·Na.
Sodium Oleoyl Isethionate is primarily used as a cleansing surfactant.
Its surface-active structure allows it to interact with oily materials and impurities, supporting their removal from the skin, hair or other surfaces during cleansing.
It can contribute to:
The European cosmetic ingredient reference identifies Sodium Oleoyl Isethionate as a surfactant-cleansing ingredient.
Sodium Oleoyl Isethionate contains a hydrophobic oleoyl portion and a hydrophilic sulfonate-containing portion.
This amphiphilic structure supports surface activity and can contribute to:
It may be combined with other compatible surfactants depending on the desired formulation characteristics.
Sodium Oleoyl Isethionate is documented as a foaming ingredient in cosmetic formulations.
Potential applications include:
Foam volume, texture and stability depend on concentration, formulation pH, surfactant combinations, electrolytes and processing conditions.
Sodium Oleoyl Isethionate can be evaluated in facial cleansing formulations.
Potential applications include:
Formulators should evaluate pH, viscosity, foam, cleansing performance, stability and final sensory characteristics.
Sodium Oleoyl Isethionate is documented as a hair-conditioning ingredient in cosmetic ingredient references.
Potential applications include:
The final conditioning effect depends on the complete formulation and the combination of surfactants and conditioning ingredients.
The hair-conditioning function is associated with improving hair manageability and sensory characteristics.
Potential formulation objectives include:
The European cosmetic ingredient reference also identifies antistatic functionality, meaning it can help reduce electrostatic charges, including those associated with hair.
Sodium Oleoyl Isethionate is also listed for antistatic functionality.
This function is particularly relevant to hair-care applications where controlling electrostatic charging can contribute to improved manageability.
Potential applications include:
Potential body-care applications include:
Its cleansing and foaming properties can support the development of personal-care cleansing products.
Isethionate salts are used as surfactants in cleansing products, and Sodium Oleoyl Isethionate can be evaluated in suitable cleansing-bar systems.
Potential applications include:
Processing characteristics should be evaluated according to the physical form and grade of the raw material.
Sodium Oleoyl Isethionate can be considered in cleansing systems where formulators are developing formulations without conventional sulfate surfactants.
Potential applications include:
The finished formulation should be evaluated for cleansing efficiency, foam, viscosity, sensory profile and stability.
Important parameters when working with Sodium Oleoyl Isethionate include:
Exact acceptance criteria should be based on the selected commercial grade and approved specification.
Processing conditions should be established according to the selected grade and physical form.
Typical considerations include:
Exact processing conditions should be established through formulation trials.
