Sulfonic Acids, C14-16-Alkane Hydroxy, Sodium Salts

Anionic surfactants
CAS 931-534-0
IUPAC: Sulfonic acids, C14-16-alkane hydroxy and C14-16-alkene, sodium salts

Ingredient-level H315 (skin irritation Cat 2) and H318 (serious eye damage Cat 1) from CLP classification data. At product-level concentrations (<0.5% in Meguiar's G18516), the finished product is classified H315 only — the H318 eye damage does not carry through to product-level classification at this concentration. Readily water-soluble; no inhalation classification.

Sulfonic acids C14-16-alkane hydroxy and C14-16-alkene sodium salts (CAS 931-534-0) is an anionic hydroxy-sulfonate surfactant. The hydroxy-sulfonate structure provides good compatibility with strongly alkaline co-builders like sodium metasilicate, making it well-suited for high-pH cleaning formulations. At ingredient-level neat concentration, CLP data shows H315 (skin irritation) and H318 (serious eye damage). At working concentrations in finished products (<0.5%), the eye classification may not carry through to the product level — Meguiar's G18516 (pH 11.5–12.4) classifies H315 at product level only. The ingredient is biodegradable per EU Detergent Regulation 648/2004 biodegradability tests (>80% CO2 evolution, OECD 301B). Aquatic toxicity data: EC50 water flea 4.53 mg/L (experimental, 48h); LC50 zebra fish ~4.2 mg/L (estimated, 96h). Not PBT or vPvB. Listed on US TSCA inventory. No Prop 65 listing.
