Polysorbate 61 is a nonionic surfactant used in cosmetic and personal care formulation development. It belongs to the polysorbate family of ethoxylated sorbitan derivatives and is associated with emulsifying and cleansing functions in cosmetic ingredient references.
Polysorbate 61 can be evaluated in suitable formulations where surface-active properties help support the dispersion or mixing of formulation components. Its performance depends on the ingredient's composition, commercial grade, concentration, processing conditions, and compatibility with other ingredients.
For cosmetic formulators, Polysorbate 61 may be considered when screening emulsifiers and surfactants for selected personal care products. Its suitability for a specific cream, lotion, cleansing product, or other formulation should be confirmed through laboratory testing rather than assumed from its ingredient classification alone.
Swapnroop provides cosmetic ingredient information to support formulation evaluation and procurement discussions. Before purchasing Polysorbate 61, confirm the exact ingredient identity, commercial grade, technical specifications, supporting documentation, packaging, and current availability.
Polysorbate 61 is identified by the INCI name Polysorbate 61. Cosmetic ingredient references describe it as a derivative of sorbitan monooctadecanoate containing polyoxyethylene groups. It is classified as a nonionic surfactant.
Polysorbates are ethoxylated derivatives of sorbitol and its anhydrides combined with fatty acids. Their hydrophilic and lipophilic characteristics allow them to be evaluated in suitable formulations involving different phases or components.
The precise composition and ethoxylation profile of a commercial Polysorbate 61 grade should be established from its technical documentation. Do not assume that its composition is identical to Polysorbate 60 or that it contains the same average ethoxylation level as another polysorbate.
Polysorbate 61 should not be confused with Polysorbate 20, Polysorbate 40, Polysorbate 60, or Polysorbate 80. These are distinct ingredient identities and may show different performance in a finished formulation. Ingredient selection and substitution should be based on verified identity, documentation, and comparative testing.
Molecular formula and molecular weight: A single universal molecular formula or molecular weight should not be assigned without an authoritative reference for the specific composition. Polysorbate materials are ethoxylated mixtures, and the values associated with an individual representative structure may not describe every commercial grade.
These are potential formulation considerations, not guaranteed product outcomes. Performance, stability, compatibility, and safety should be established through appropriate testing.
Polysorbate 61 may be evaluated in suitable formulations where emulsifying performance is required. The results depend on the complete ingredient system, processing method, and characteristics of the dispersed phases.
Its listed cleansing function makes Polysorbate 61 relevant to the assessment of selected cleansing products. Formulators should evaluate cleansing performance, rinsability, appearance, and compatibility with the other ingredients.
Polysorbate 61 may be screened for suitable cream and lotion formulations when its documented characteristics align with the emulsifier system. Finished-product texture, viscosity, and stability should be assessed during development.
The ingredient may be investigated in selected personal care formulations where its verified properties meet the intended technical requirements. Suitability should be established through formulation trials.
Formulation teams may compare Polysorbate 61 with other nonionic surfactants during product development. Differences in chemical composition and grade should be considered before selecting an ingredient or replacing another polysorbate.
Other applications may be investigated when the commercial grade's technical documentation supports the intended use. Do not assume suitability for every skin-care, hair-care, or fragrance-containing formulation without appropriate evidence.
Polysorbate 61 appears in cosmetic ingredient references with cleansing and emulsifying functions. The European Commission's CosIng database provides ingredient information, but an inventory entry is not, by itself, proof of unrestricted use or regulatory approval for every cosmetic application.
A Cosmetic Ingredient Review assessment examined several polysorbates as a group. Any safety conclusion should be interpreted within the scope and conditions of that assessment rather than applied automatically to every commercial grade or use.
Before commercialisation, review the supplier's safety data sheet, confirm the applicable requirements in each target market, and complete an appropriate safety assessment for the finished cosmetic product.
Swapnroop supports cosmetic ingredient evaluation by providing product information for formulation and procurement discussions.
Confirm the offered grade, supporting documentation, current availability, and commercial terms before ordering.
Polysorbate 61 is a nonionic surfactant identified by the INCI name Polysorbate 61 and CosIng reference 79322. Cosmetic ingredient references list cleansing and emulsifying functions for this ingredient.
Cosmetic manufacturers in India should evaluate Polysorbate 61 based on verified ingredient identity, commercial grade, composition, quality documentation, intended application, and applicable regulations. Laboratory testing is necessary to determine whether it meets the performance requirements of the finished product.
Contact Swapnroop to discuss Polysorbate 61 requirements, including intended use, required grade, quantity, packaging, and documentation needs. Confirm current availability and commercial terms before procurement.
For bulk procurement, provide the intended application, required grade, quantity, packaging preference, and documentation requirements. Before accepting a batch, compare the certificate of analysis with the agreed product specification and review the relevant technical and safety documentation.
For new formulations, complete laboratory trials and appropriate compatibility, stability, and safety testing before moving to pilot or commercial production. Maintain incoming-material checks and batch records to support consistent manufacturing quality.
