Product Description of Sodium Oleate CAS#143‑19‑1 Sodium octadecenoate, more commonly referred to as sodium oleate, has a molecular formula of C₁₇H₃₃CO₂Na. As an organic substance, it ranks among the major constituents of soap products produced from olive oil and animal tallow.
This chemical can be synthesized when oleic acid undergoes a neutralization reaction with sodium hydroxide. Possessing an amphiphilic molecular framework with both water‑attracting and oil‑attracting segments, sodium oleate delivers outstanding performance in emulsification, penetration and soil removal.
It dissolves efficiently within hot water, which expands its usability across multiple industrial scenarios. It serves as a prevalent anionic‑type surface‑active agent and is frequently deployed as a water‑repellent additive for textile fabrics.
