Does BY-160 / PEG-60 Castor Oil represent one discrete molecule?

No. PEG-60 Castor Oil is an ethoxylated castor-oil composition, not a single molecule. “60” is a nominal ethylene-oxide addition level and the material retains a distribution derived from castor oil. Confirm the offered grade’s specified EO level, hydroxyl value, saponification value, water, appearance and stated methods.

Can PEG-60 Castor Oil be substituted with PEG-35 Castor Oil or a hydrogenated castor-oil ethoxylate?

Not automatically. These materials can have different nominal EO levels, source oils, physical forms and specification profiles even where related names or CAS references occur. Compare the agreed grade definition and the intended system’s response, including solubilisation, emulsification, cloud point and phase behaviour, before replacement.

Does the name PEG-60 Castor Oil establish a controlled or compendial grade?

No. A generic name and CAS reference do not confirm compliance with a named monograph or destination-specific requirement. Identify the intended use and standard first, then review the actual grade’s specification, documentary status and batch data. Suitability remains specific to the finished formulation and market.

BY-160 / PEG-60 Castor Oil CAS 61791-12-6

BY-160 is a commercial PEG-60 castor oil grade: a nonionic, variable-composition reaction product of castor oil and ethylene oxide with a nominal average of about 60 EO units. CAS 61791-12-6 identifies the wider castor-oil ethoxylate family and does not by itself fix the EO number or product specification. Confirm the current COA/TDS before formulation or substitution.

CAS: 61791-12-6
Synonyms: BY-160; PEG-60 castor oil; Polyoxyethylene (60) castor oil; Castor oil ethoxylate 60EO
Einecs: 500-151-7
Molecular Formula: Castor-oil-derived ethoxylate mixture with nominal average ≈60 EO for this commercial grade; distribution of glyceride-, ricinoleate- and PEG-derived species. No single exact molecular formula.
Grade: Confirm the nominal EO or PO level, feedstock range, active matter, water, physical form and relevant analytical values against the current TDS and COA.
Package: State required quantity, physical form and destination; confirm the current bag or container, liner, net weight, temperature handling and transport requirements before quotation.

Technical Specifications

Property	Specification
Chemical identity	Castor oil, ethoxylated; commercial PEG-60 castor oil grade
Nominal ethoxylation	About 60 EO for BY-160 / PEG-60; confirm by the supplier's grade specification
Appearance	Supplier specification at the stated temperature; may vary with grade and temperature
Hydroxyl / saponification / acid values	Current COA/TDS with the applicable test methods
Active matter / water	Batch COA specification; not a single compound with 99% molecular purity

Applications

For compatible industrial oil-in-water emulsification, solubilisation, dispersion and process formulations, including selected cleaning, textile and agrochemical systems. Determine dosage and stability in the complete formulation. Cosmetic, food or pharmaceutical use requires a specifically qualified grade and supporting documents.

Storage

Keep sealed in the original container in a dry, ventilated area at the temperature stated in the current TDS/SDS. Protect from contamination, moisture, heat and incompatible materials; condition a viscous or pasty product only as instructed by the supplier.

Safety / Regulatory

Review the current SDS before handling and apply the required controls and PPE. PEG-60 castor oil is not an alkylphenol ethoxylate by chemical identity, but an APEO-free claim must be supported by a supplier declaration or agreed analytical limit. Do not transfer regulatory or safety claims from hydrogenated or pharmaceutical grades.
