Sodium Myreth Sulfate is an anionic surfactant used in cosmetic and personal care formulations for cleansing, foaming and surface-active performance. It is the sodium salt of sulfated, ethoxylated myristyl alcohol and is commonly used in rinse-off products that require effective cleansing and foam formation.
The ingredient helps water interact with oily residues, dirt and other surface impurities, supporting their removal during rinsing. It can also contribute to foam generation and help improve the cleansing experience in suitable shampoos, body washes, shower gels and other personal care preparations.
Sodium Myreth Sulfate contains a fatty alcohol-derived chain with ethoxylated units and a sulfate group paired with sodium. Its composition distinguishes it from Sodium Lauryl Sulfate and Sodium Laureth Sulfate. These ingredients have related surfactant functions but are not identical in chemical identity.
Commercial Sodium Myreth Sulfate grades may differ in active matter, ethoxylation profile, physical form, pH and other quality parameters. Cosmetic manufacturers should review the technical specifications for the selected grade and evaluate its compatibility with the complete formulation before use.
For ingredient selection and quality control, important considerations include cleansing performance, foam characteristics, active concentration, pH, viscosity, compatibility with other surfactants and suitability for the intended application.
Sodium Myreth Sulfate is an anionic surfactant derived from ethoxylated myristyl alcohol. The ethoxylated alcohol is sulfated and neutralized with sodium to form the corresponding sodium salt.
The INCI name is Sodium Myreth Sulfate. The ingredient is primarily used as a cleansing agent and surfactant in cosmetic formulations. It can also contribute to foaming and emulsifying functions in suitable product systems.

Sodium Myreth Sulfate consists of a fatty alcohol-derived hydrophobic segment, ethoxylated units and a sulfate group associated with sodium. The myreth designation refers to the myristyl-based ether sulfate structure.
The degree of ethoxylation and the composition of a commercial grade can influence its physical properties and formulation performance. Sodium Myreth Sulfate should not be confused with Sodium Lauryl Sulfate, which is non-ethoxylated, or Sodium Laureth Sulfate, which is based on an ethoxylated fatty alcohol profile that may differ from the myristyl-based material.
Commercial products can vary in fatty alcohol chain distribution and ethoxylation profile. Therefore, a molecular formula or molecular weight for one defined structure should not automatically be applied to every commercial grade.
For reliable identification, confirm the INCI name, CAS number, active matter and chemical description using the current technical documentation for the selected material.
Sodium Myreth Sulfate functions as an anionic surfactant. Surfactants help reduce the surface tension of water and support interactions between water, oily materials and surface impurities.
During cleansing, the ingredient helps loosen and disperse residues so they can be removed during rinsing. It can also support foam formation, which contributes to the sensory experience of shampoos and other cleansing products.
The final performance depends on the surfactant concentration, water quality, formulation pH, viscosity modifiers and the presence of other surfactants or conditioning ingredients. Foam volume alone does not establish the mildness or overall quality of a finished product.
Sodium Myreth Sulfate supports the removal of oils, dirt and surface impurities in suitable cosmetic cleansing formulations.
Its surface-active properties help generate foam during use, contributing to the sensory characteristics of rinse-off products.
The ingredient helps water interact with oily materials and surface residues, supporting cleansing and rinsability.
It can be evaluated in selected shampoos, body washes, shower gels and other compatible cleansing preparations.
Sodium Myreth Sulfate may be combined with compatible anionic, amphoteric or nonionic surfactants to adjust cleansing performance, foam characteristics and viscosity.
Its established cleansing and foaming functions make it a candidate for formulators developing suitable rinse-off cosmetic products.
The actual performance of the ingredient depends on the grade, concentration and complete formulation. Product-specific testing is necessary to establish suitability.
Sodium Myreth Sulfate may be used in selected shampoo formulations to support cleansing and foam formation. Formulators should assess cleansing strength, viscosity, rinsability and scalp compatibility.
In suitable body washes, the ingredient helps remove surface oils and impurities. The overall surfactant system should be evaluated for the intended skin-contact conditions.
Sodium Myreth Sulfate can be considered for shower gel formulations where its cleansing and foaming properties meet the product requirements.
The ingredient may be evaluated in selected rinse-off facial cleansers. The formulation requires appropriate assessment of surfactant concentration, skin compatibility and eye-area exposure.
Sodium Myreth Sulfate may contribute to foam generation in compatible bath preparations. The finished product should be evaluated for foam stability, skin compatibility and intended exposure.
The ingredient can be assessed in other suitable liquid cleansing products where anionic surfactant activity is required.
Sodium Myreth Sulfate may be combined with compatible surfactants to adjust foam, cleansing behaviour and viscosity. Compatibility and stability should be established through laboratory trials.
Sodium Myreth Sulfate is an anionic surfactant used in selected cosmetic and personal care cleansing formulations. Its principal functions include cleansing and foaming, with emulsifying support possible in suitable systems.
Cosmetic manufacturers in India should evaluate the selected grade's identity, active matter, composition and technical specifications before incorporating it into a finished formulation. Batch documentation and formulation testing help establish whether the ingredient meets the intended product requirements.
For procurement through Swapnroop, confirm current availability, commercial grade, packaging options and applicable quality documentation before placing an order.
Bulk procurement requires consistent ingredient identification, suitable quality controls and documentation for the selected commercial grade.
Before purchasing larger quantities, manufacturers should review the product specification, batch COA, storage requirements and shelf-life information. Packaging formats, order quantities, lead times and commercial terms should be confirmed directly with Swapnroop.
When evaluating Sodium Myreth Sulfate from Swapnroop, cosmetic manufacturers should confirm that the selected grade meets their formulation and procurement requirements.
Important considerations include:
Review the applicable product documentation before approving the ingredient for manufacturing.
Sodium Myreth Sulfate is an anionic surfactant and cleansing agent derived from sulfated, ethoxylated myristyl alcohol. It is used in selected cosmetic and personal care products.
The commonly listed CAS number is 25446-80-4. Commercial grades may use different identifiers depending on their composition, so verify the number against the applicable product documentation.
The INCI name is Sodium Myreth Sulfate.
Its main functions are cleansing, foaming and surfactant activity. It may also provide emulsifying support in suitable formulations.
Sodium Myreth Sulfate is based on sulfated, ethoxylated myristyl alcohol, whereas Sodium Lauryl Sulfate is a non-ethoxylated sulfate surfactant. They have different chemical identities.
No. Both are anionic surfactants, but their fatty alcohol chain profiles and ethoxylation characteristics may differ. Confirm the precise INCI identity when selecting a raw material.
It may be used in suitable shampoo and body wash formulations for cleansing and foam formation. The final formulation should be evaluated for stability, cleansing performance and skin compatibility.
Suitability depends on concentration, exposure, the complete formulation and individual tolerance. Surfactants can cause irritation, so appropriate safety and compatibility testing is necessary.
Sodium Myreth Sulfate can be represented by a general structure such as CH₃(CH₂)₁₃(OCH₂CH₂)ₙOSO₃Na, where n represents the number of ethoxylated units. Commercial material can contain a distribution of structures, so a single molecular formula or molecular weight may not represent every grade.
