text: N-Oleoylsarcosine is a clear, yellow to brown, viscous liquid, which is sparsely soluble in water and acts acidic. As long-chain N-acylamino acid, the surfactant is soluble in many organic solvents and in mineral oil. In the alkaline it dissolves well in water. Because of its carboxamide structure, Sarkosyl O is chemically stable even at high pH values and strongly foaming as an anionic surfactant. N-oleyl sarcosine is only slightly toxic and easily biodegradable.
