TEA-Lauryl Sulfate is an anionic surfactant used in cosmetic and personal care formulations for cleansing, foaming and surface-active performance. Also known as Triethanolamine Lauryl Sulfate, it is the triethanolamine salt of lauryl sulfuric acid. Its surfactant properties make it relevant to selected shampoos, body cleansers, shower gels and other cleansing preparations.
TEA-Lauryl Sulfate helps water spread across surfaces and supports the removal of oil, dirt and other residues during cleansing. It can also contribute to foam formation and help support formulation performance when incorporated into a compatible surfactant system.
The ingredient's behaviour depends on its purity, active matter, physical form, pH and other grade-specific properties. Commercial materials may differ in appearance, concentration and technical specifications. Cosmetic manufacturers should therefore evaluate the selected grade against their formulation requirements and obtain the relevant technical documentation before use.
For product developers, important considerations include cleansing performance, foam characteristics, compatibility with other surfactants, pH control, stability and suitability for the intended application.
TEA-Lauryl Sulfate is an anionic surfactant formed from lauryl sulfuric acid and triethanolamine. In cosmetic ingredient nomenclature, TEA refers to triethanolamine. The ingredient is identified by the INCI name TEA-Lauryl Sulfate.
It is used primarily to provide cleansing and foaming functionality in appropriate personal care formulations. Its performance depends on the concentration used and the characteristics of the complete formulation.

TEA-Lauryl Sulfate contains a lauryl sulfate component paired with a triethanolammonium counter-ion. This structure distinguishes it from sodium lauryl sulfate and ammonium lauryl sulfate, which use different counter-ions.
The chemical identity should be distinguished from TEA-Laureth Sulfate. TEA-Laureth Sulfate is an ethoxylated material, whereas TEA-Lauryl Sulfate refers to the lauryl sulfate salt. These ingredient names are not interchangeable.
Commercial specifications should identify the material accurately and state the applicable CAS number, composition, active matter and quality parameters. The exact documentation supplied with the selected grade should take precedence over general ingredient descriptions.
TEA-Lauryl Sulfate functions as an anionic surfactant. Surfactants reduce the surface tension of water and support interactions between water and oily or particulate residues. During cleansing, this can help loosen and disperse impurities so they can be removed during rinsing.
The ingredient can also contribute to foam formation. Foam volume, stability and texture depend on the surfactant concentration, water quality, formulation pH and the presence of other ingredients.
Its practical performance should be evaluated in the complete formulation rather than inferred from the ingredient's identity alone.
TEA-Lauryl Sulfate helps remove excess oils, dirt and surface residues from skin and hair in suitable cleansing formulations.
Its surfactant activity supports foam generation, which can contribute to the sensory experience of rinse-off personal care products.
The ingredient supports wetting and cleansing by helping water interact with oily materials and surface impurities.
It can be evaluated for use in selected shampoos, body cleansers and other compatible personal care products, depending on the grade and intended application.
When properly formulated, it may be combined with compatible anionic, amphoteric or nonionic surfactants to adjust cleansing and foam characteristics.
Its established surfactant function makes it a material that formulators can evaluate when developing cleansing systems requiring anionic surfactant activity.
Actual performance and skin compatibility depend on the grade, concentration, other ingredients and intended conditions of use.
TEA-Lauryl Sulfate may be evaluated in selected shampoo formulations for cleansing and foam generation. The formulation should be assessed for scalp compatibility, cleansing strength, viscosity and rinsability.
In suitable body cleansing products, the ingredient can support the removal of surface oils and impurities. Formulators should evaluate the overall surfactant system for the intended skin-contact conditions.
TEA-Lauryl Sulfate may be considered for selected shower gel formulations where its cleansing and foaming properties meet the product requirements.
The ingredient may be evaluated in other compatible liquid cleansing systems. Its use should be based on grade-specific technical guidance and finished-product testing.
TEA-Lauryl Sulfate can be assessed alongside compatible surfactants to adjust cleansing performance, foam characteristics and formulation behaviour. Compatibility and stability should be established through laboratory trials.
Its suitability for additional cosmetic applications should be determined by the product's function, exposure conditions, applicable requirements and the technical profile of the selected material.
TEA-Lauryl Sulfate is an anionic surfactant used in selected cosmetic and personal care cleansing formulations. Its primary functions include cleansing and foaming, with additional surfactant functionality depending on the formulation.
Cosmetic manufacturers in India should evaluate the ingredient's identity, active matter, technical specifications and compatibility with the intended product before procurement and production. Grade-specific documentation is important for establishing suitability and quality acceptance.
For procurement through Swapnroop, confirm the current availability, commercial grade, packaging and applicable quality documents before placing an order.
When sourcing TEA-Lauryl Sulfate for cosmetic manufacturing, buyers should verify the material's identity, concentration, appearance, pH and applicable quality parameters. The selected grade should meet the formulation's performance and documentation requirements.
Availability, packaging options, commercial terms and dispatch details should be confirmed directly with Swapnroop.
Bulk procurement requires consistent identification, appropriate 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.
Confirm the available packaging formats, order quantities, lead time and current commercial terms with Swapnroop.
When evaluating TEA-Lauryl Sulfate from Swapnroop, cosmetic manufacturers should confirm that the selected grade meets their technical and procurement requirements.
Important considerations include:
Review the applicable product documentation before approving the ingredient for manufacturing.
What is TEA-Lauryl Sulfate?
TEA-Lauryl Sulfate is an anionic surfactant, also called Triethanolamine Lauryl Sulfate, used in selected cosmetic and personal care formulations for cleansing and foaming.
What is the CAS number of TEA-Lauryl Sulfate?
CAS 139-96-8 is a commonly listed identifier. A second identifier, 68908-44-1, is reported in some ingredient databases for generic material. Confirm the correct identifier against the exact commercial grade.
Where is TEA-Lauryl Sulfate used?
It may be used in selected shampoos, body cleansers, shower gels and compatible cleansing formulations, subject to grade suitability and finished-product evaluation.
What should buyers verify before purchasing TEA-Lauryl Sulfate?

TEA-Lauryl Sulfate is the triethanolamine salt of lauryl sulfuric acid. TEA-Laureth Sulfate is an ethoxylated material. They are different ingredient identities and should not be treated as interchangeable.
No. Both are lauryl sulfate surfactants, but TEA-Lauryl Sulfate uses a triethanolammonium counter-ion, whereas Sodium Lauryl Sulfate uses a sodium counter-ion.
It may be evaluated for suitable shampoo formulations to provide cleansing and foaming. The finished formulation should be assessed for performance, stability and scalp compatibility.
Suitability depends on the concentration, formulation, exposure and individual tolerance. Surfactants can cause irritation, so the finished product should undergo appropriate safety and compatibility assessment.
The ingredient is commonly represented by the combined composition C₁₂H₂₆O₄S · C₆H₁₅NO₃, corresponding to the triethanolamine salt of lauryl sulfuric acid. This representation gives an overall formula of C₁₈H₄₁NO₇S for the defined 1:1 salt.
