Is a Triton X-100-type grade automatically equivalent to branded Triton X-100?

No. The type designation describes an octylphenol-ethoxylate profile and does not establish branded origin or identical performance. Compare EO distribution, active matter, water content and cloud point under the same test conditions, then evaluate wetting, emulsification, foam and stability in the intended formulation.

Is a Triton X-100-type octylphenol ethoxylate suitable for every destination market?

No. This is an APEO, so destination-market rules and customer APEO restrictions affect selection. In the EU/EEA, the 4-tert-octylphenol ethoxylate group is subject to REACH Annex XIV authorisation requirements. Any required authorisation or exemption must cover the actual use and supply chain. Include the application and destination in the quotation request.

What can LC/HPLC quality information show for a Triton X-100-type grade?

An appropriate LC/HPLC method can show the ethoxylate-homologue distribution. Free PEG is a separate analytical target and needs a suitable method, detector, calibration and molecular-mass range. A distribution fingerprint or normalized peak-area percentage alone does not establish mass purity or total active matter.

Triton X-100-Type Octylphenol Ethoxylate CAS 9002-93-1

Octylphenol Ethoxylate (CAS 9002-93-1), also called Triton X-100-type or polyethylene glycol tert-octylphenyl ether, is a nonionic surfactant with a reference average of about 9.5 ethylene-oxide units. “Triton X-100” is used here as a type reference, without a claim of branded origin. Grade selection is based on EO distribution, active matter content, water content, appearance and cloud point, together with APEO/REACH requirements for the intended market. A Certificate of Analysis (COA), Technical Data Sheet (TDS) and Safety Data Sheet (SDS) are available for the quoted grade.

CAS: 9002-93-1
Synonyms: Triton X-100-type; Octylphenol ethoxylate; Octoxynol-type surfactant; Polyethylene glycol tert-octylphenyl ether
Molecular Formula: t-C₈H₁₇–C₆H₄–O–(CH₂CH₂O)ₙ–H; homologue distribution, reference average n≈9–10 (about 9.5). No single exact molecular formula.
Grade: X-100-type nonionic surfactant grade, specified by EO distribution, active matter, water, appearance and cloud point under the agreed test conditions; HLB is a selection reference.
Package: Drum or bulk packaging; container, liner and net weight are specified in the quotation for the order quantity, destination and handling requirements.

Technical Specifications

Property	Specification
CAS number	9002-93-1
Chemical identity	Polyethylene glycol tert-octylphenyl ether; a distribution of octylphenol ethoxylate homologues.
EO profile	An X-100-type reference average of about 9.5 EO; the quoted grade is specified by its average and ethoxylate distribution.
Appearance	Colour and physical form stated at the inspection temperature for the quoted grade.
Cloud point	Reported in °C with the solution concentration, concentration basis, test medium and method.
HLB	A grade-selection reference; the source or calculation basis is stated with the value.
Active matter	Reported as % w/w with the agreed method and sample basis; distinguished from non-volatile solids and the purity of a single homologue.
Water	Reported as % w/w using an appropriate Karl Fischer method.

Cloud point is compared under matching test conditions. A result for 1% product in water is not necessarily the same as one for 1% active matter, or a value measured in an electrolyte solution. HLB is a selection reference and does not replace formulation testing.

For agreed quality requirements, we can provide applicable LC/HPLC test information for the ethoxylate distribution or free PEG. A distribution fingerprint and a calibrated mass-content result address different questions. The report states the detector, calibration, reporting basis and applicable molecular-mass range; normalized peak area alone does not establish mass purity or total active matter.

Applications

Triton X-100-type octylphenol ethoxylate provides wetting, emulsification and detergency in compatible industrial cleaning and emulsion formulations. Performance depends on the oil phase, operating temperature, electrolyte content and the complete formulation.

OP-7 octylphenol ethoxylate provides a lower-nominal-EO comparison, while OP-10 octylphenol ethoxylate is closer to the X-100-type reference EO level. Triton X-114-type octylphenol ethoxylate offers a lower-cloud-point comparison. Grade data and formulation trials determine which profile fits the process; these names do not establish one-to-one interchangeability.

For formulations moving away from alkylphenol ethoxylates, C9-11 alcohol ethoxylate is a separate candidate. Select its EO grade and compare wetting, emulsification, foam and compatibility at the process temperature. The alcohol-chain range alone does not establish an equivalent grade or an APEO test result.

Storage

Store sealed in a clean, dry area under the conditions in the supplied TDS and SDS. Protect the material from contamination, moisture, excessive heat and incompatible materials. Any low-temperature conditioning or mixing procedure is specified for the grade.

Safety / Regulatory

Use the protective equipment and handling controls stated in the supplied SDS, and prevent release to drains or watercourses. Octylphenol ethoxylate is an alkylphenol ethoxylate (APEO) and does not meet an APEO-free formulation requirement. For EU/EEA use, any required REACH Annex XIV authorisation or exemption must cover the actual use and supply chain.

Send the application or an existing specification, quantity and destination for a quotation. Include any required active-matter basis, cloud-point test conditions or impurity limits so the quoted grade and supporting quality information match the procurement requirement.
