Through surface tension measurements, the following values were determined: the critical micelle concentration (CMC) and the surface tension at the CMC (γ<jats:sub>CMC</jats:sub>). The following values were calculated: area per molecule at the CMC (A<jats:sub>CMC</jats:sub>), standard free energy change of micellization (Δ<jats:italic>G</jats:italic><jats:sub>mic</jats:sub><jats:sup>o</jats:sup>), standard free energy of adsorption (Δ<jats:italic>G</jats:italic><jats:sub>ad</jats:sub><jats:sup>o</jats:sup>), and the “efficiency” of a surfactant in reducing surface tension (pC<jats:sub>20</jats:sub>). The micelle aggregation numbers were measured through steady‐state fluorescence‐quenching methods. As the chain length of the hydrocarbon of <jats:italic>n</jats:italic>‐alkylnaphthalene sulfonate increased, the Krafft temperature increased, the surface tension decreased, the value of CMC decreased, pC<jats:sub>20</jats:sub> increased, Δ<jats:italic>G</jats:italic><jats:sub>ad</jats:sub><jats:sup>o</jats:sup> and Δ<jats:italic>G</jats:italic><jats:sub>mic</jats:sub><jats:sup>o</jats:sup> became more negative, and the micelle aggregation number increased. The results showed that sodium α‐(<jats:italic>n</jats:italic>‐decyl)naphthalene sulfonate (DNS) had a high pC<jats:sub>20</jats:sub>, low Krafft temperature, and lower CMC than other surfactants in this study. Thus, DNS and the other <jats:italic>n</jats:italic>‐alkylnaphthalene surfactants studied exhibit desirable properties that may be of value in some fields such as detergency, oil recovery, and dyes.</jats:p>","journal":"Journal of Surfactants and Detergents","year":2004,"id":25791,"datarank":1.0850117850861187,"base_score":2.5649493574615367,"endowment":2.5649493574615367,"self_citation_contribution":0.38474240361923057,"citation_network_contribution":0.7002693814668881,"self_endowment_contribution":0.38474240361923057,"citer_contribution":0.7002693814668881,"corpus_percentile":null,"corpus_rank":null,"citation_count":12,"citer_count":10,"citers_with_citation_signal":9,"citers_with_endowment":9,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":15685,"name":"Lu Zhang","orcid":"0000-0002-4858-0361","position":1,"is_corresponding":false},{"id":150811,"name":"Sui Zhao","orcid":null,"position":2,"is_corresponding":false},{"id":150812,"name":"Jiayong Yu","orcid":null,"position":3,"is_corresponding":false},{"id":150813,"name":"Jingyi An","orcid":null,"position":4,"is_corresponding":false},{"id":150810,"name":"Xiaoli Tan","orcid":null,"position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"base_score":2.5649493574615367,"endowment":2.5649493574615367,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"24523987","pmcid":null,"openalex_id":"https://openalex.org/W2049640443","authors":[],"funders":[],"total_grants":0,"fwci":0.4591,"citation_percentile":0.62317631,"influential_citations":0,"citation_trend":[{"year":2012,"count":2},{"year":2015,"count":2},{"year":2016,"count":1},{"year":2020,"count":1},{"year":2025,"count":1}],"oa_status":"closed","license":"http://onlinelibrary.wiley.com/termsAndConditions#vor","oa_locations":[{"url":"https://aocs.onlinelibrary.wiley.com/doi/pdf/10.1007/s11743-004-0296-8","host_type":"publisher"},{"url":"https://doi.org/10.1007/s11743-004-0296-8","host_type":"journal"}],"fields_of_study":["Surfactants and Colloidal Systems","Environmental Chemistry and Analysis","Analytical Chemistry and Chromatography","Chemistry","Materials Science"],"mesh_terms":[],"keywords":["Krafft temperature","Chemistry","Critical micelle concentration","Thermodynamics of micellization","Pulmonary surfactant","Surface tension","Aggregation number","Sulfonate","Adsorption","Micelle","Gibbs isotherm","Hydrocarbon","Quenching (fluorescence)","Analytical Chemistry (journal)","Sodium","Inorganic chemistry","Organic chemistry","Aqueous solution","Fluorescence","Thermodynamics"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Affordable and clean energy"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-06-08T08:09:36.163807Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
