PEG-20 Sorbitan Isostearate is a non-ionic surfactant used in cosmetic and personal care formulations. It is associated with Polyoxyethylene (20) Sorbitan Monoisostearate and is valued for its emulsifying, cleansing and solubilizing functions in suitable formulations.
This ingredient combines an ethoxylated sorbitan structure with an isostearate component. Its molecular characteristics help formulators select it for applications where interactions between oil-based and water-based ingredients need to be managed. Actual performance depends on the commercial grade, formulation composition, processing conditions and intended product characteristics.
Swapnroop provides product information for businesses exploring cosmetic ingredients for skincare, cleansing and other personal care applications. Buyers should verify the exact ingredient identity, grade, technical specifications and availability before procurement.
PEG-20 Sorbitan Isostearate is an ethoxylated sorbitan fatty-acid ester associated with the INCI name PEG-20 Sorbitan Isostearate. The number “20” refers to an average of approximately 20 moles of ethylene oxide in the ingredient’s naming convention. Commercial materials may contain a distribution of related molecular species rather than one single molecular structure.
The isostearate component distinguishes this ingredient from related materials such as PEG-20 Sorbitan Stearate, PEG-20 Sorbitan Oleate and Sorbitan Isostearate. Although these ingredients have related naming patterns, they are not interchangeable without evaluating their identity and formulation performance.
PEG-20 Sorbitan Isostearate is identified by CAS No. 66794-58-9 in several cosmetic ingredient references. Its reported functions include emulsifying, cleansing surfactant and solubilizing surfactant functions. The exact role in a finished product should be determined through formulation development and compatibility testing.
These are potential formulation benefits, not guaranteed performance outcomes. The finished product's properties depend on the full formulation and the grade selected.
PEG-20 Sorbitan Isostearate may be evaluated in suitable skincare formulations where emulsification or solubilization support is required. Its suitability depends on the other ingredients, the intended texture and the stability requirements of the finished product.
Formulators may assess this ingredient in selected cream and lotion systems. The required emulsifier combination should be determined through compatibility studies, stability testing and evaluation of the product's intended characteristics.
Its surfactant properties may make it relevant to selected cleansing formulations. The ingredient's suitability depends on the product type, cleansing system, concentration and compatibility with other formulation components.
PEG-20 Sorbitan Isostearate can be evaluated in personal care emulsions that require an appropriate emulsifying or solubilizing ingredient. Formulators should assess its effect on appearance, viscosity, homogeneity and storage stability.
Product developers may consider this ingredient when exploring particular surfactant systems or combinations of cosmetic ingredients. Suitability must be confirmed for the intended application rather than assumed from the ingredient name alone.
The recommended usage concentration, incorporation procedure and processing conditions should be confirmed from the technical documentation for the specific commercial grade. There is no single usage level or processing method that applies universally to every formulation.
During product development, evaluate:
Follow the relevant Safety Data Sheet (SDS) and technical data sheet for handling, storage and safety precautions. Use approved quality-control procedures when receiving and evaluating the material.
Before purchasing PEG-20 Sorbitan Isostearate, confirm the INCI name, CAS number, grade and intended application. Request the available Certificate of Analysis (CoA), Safety Data Sheet and technical data sheet for the actual commercial product.
The purchasing specification should define relevant quality parameters, test methods, acceptance criteria, packaging and storage conditions. Values should be based on the approved specification for the selected grade rather than assumptions drawn from a related ingredient.
Swapnroop supports product enquiries for businesses evaluating cosmetic ingredients for personal care formulation requirements. Providing the intended application, required grade, quantity and documentation needs helps clarify the material being requested.
Before placing an order, buyers should confirm availability, packaging, lead time and applicable technical documents. Product identity and batch documentation should correspond to the material being supplied.
Businesses in India looking for PEG-20 Sorbitan Isostearate for cosmetic and personal care formulations should verify the exact ingredient identity and grade before procurement. This ingredient is associated with Polyoxyethylene (20) Sorbitan Monoisostearate and CAS No. 66794-58-9.
Swapnroop welcomes enquiries from cosmetic manufacturers, formulation teams and ingredient purchasing professionals seeking product information and sourcing support. Share your application, required grade, estimated quantity and documentation requirements to help assess your needs.
PEG-20 Sorbitan Isostearate is a non-ionic surfactant used in cosmetic and personal care formulations. It is associated with Polyoxyethylene (20) Sorbitan Monoisostearate.
The commonly associated CAS number is 66794-58-9. Verify this identifier against the documentation for the specific commercial grade.
The INCI name is PEG-20 Sorbitan Isostearate.
Its reported cosmetic functions include emulsifying, cleansing surfactant and solubilizing surfactant functions. The appropriate role depends on the finished formulation.
Yes. It is classified as a non-ionic surfactant and can be evaluated for appropriate cosmetic formulation applications.
It may be considered for selected skincare formulations where its emulsifying or solubilizing properties are appropriate. Compatibility and stability testing are necessary.
No. They are different ingredient identities associated with different fatty-acid components. Confirm the INCI name and CAS number before selecting either ingredient.
The appropriate concentration depends on the commercial grade, formulation and intended function. Follow the grade-specific technical documentation and establish the suitable level through formulation trials.
Request the applicable Certificate of Analysis, Safety Data Sheet and technical data sheet. Confirm the ingredient identity, quality parameters, test methods and acceptance criteria.
Provide the required grade, intended application, quantity and technical documentation requirements to Swapnroop so that the sourcing enquiry can be assessed.
