Product Description
Octylphenol Ethoxylate (OP Series) is a series of ethoxylated octylphenol nonionic surfactants identified by CAS 9002-93-1.
Synonyms: Octylphenol ethoxylate; OP series; Polyoxyethylene octylphenyl ether; Octoxynol; Polyethylene glycol octylphenyl ether.
CAS: 9002-93-1.
Molecular formula: Variable ethoxylate distribution.
Confirm OP grade, average EO number, active content, HLB target, application, quantity, packaging, and documents before purchase.
It is mainly evaluated as a wetting agent, emulsifier, dispersant, and cleaning agent where the grade-specific HLB and cloud point fit the formulation.
Confirm the current product-specific specification.
Confirm packaging requirements with quantity, destination, and handling needs.
Document requirements should be confirmed from the current specification, SDS, COA, or other product-specific files.
Regulated-use suitability must be confirmed separately with current product-specific documentation.

FAQ - Technical & Supply Chain
-
Q:
Does CAS 9002-93-1 represent one fixed Octylphenol Ethoxylate grade?
A: No. CAS 9002-93-1 covers the octylphenol ethoxylate or OP series, including grades such as OP-4, OP-9, OP-10, OP-20 and OP-40. Each grade has a different average ethylene oxide number, so the exact OP number or required EO range should be stated instead of only the CAS number. -
Q:
Which specifications should be compared for the OP series?
A: Compare average EO number, active content, water, pH, color, cloud point, HLB, hydroxyl value and the oligomer distribution. Appearance also changes with grade, from colorless or pale yellow liquid for lower EO products to paste or solid for higher EO products such as OP-40. -
Q:
What is Octylphenol Ethoxylate used for?
A: OP-series ethoxylates are nonionic surfactants used as wetting agents, emulsifiers, dispersants and cleaning agents. Lower-EO grades are used in oil-soluble emulsification and industrial cleaning, while OP-9/OP-10 are used in textile auxiliaries, emulsion polymerization and aqueous formulations; higher-EO grades are used as solubilizers or stabilizers. -
Q:
How do I choose between OP-10, OP-40 and other grades?
A: Choose by the required HLB, water solubility, cloud point and formulation type. OP-10 is water soluble and commonly used for wetting, emulsifying and cleaning, while OP-40 has a higher EO content and HLB and is more suitable where stronger hydrophilic character or higher-temperature stability is needed. -
Q:
Are octylphenol ethoxylates restricted in the EU?
A: Octylphenol ethoxylates and nonylphenol ethoxylates are included in EU REACH Annex XIV, so covered EU uses have required authorization since 4 January 2021. Confirm the intended use, destination and current compliance status before selecting this product, because alkylphenol ethoxylate-free alternatives may be preferred in some markets.
