Versatile oleic acid derivative with outstanding performance as a froth flotation collector for tungsten, lithium, and fluorite ores — and as a corrosion inhibitor and surfactant for industrial and personal care applications. Multiple grades available.
N-Oleoyl Sarcosine (N-OSS) is an N-acyl amino acid surfactant produced by condensation of oleic acid with sarcosine (N-methylglycine), followed by acidification and refining. Its molecular structure — a long C18 oleic acid chain combined with a polar sarcosine head group — gives it an amphiphilic character that enables exceptional performance across a wide range of industrial and specialty chemical applications.
ZHAOYUAN supplies N-Oleoyl Sarcosine in four grades (Special Grade through Grade 3), available in 50 kg and 200 kg plastic drums or IBC totes. The product is a yellow to light brown oily liquid at room temperature, biodegradable, and stable for a minimum of 24 months under recommended storage conditions.

Its two primary applications are as a froth flotation collector for tungsten minerals (wolframite, scheelite), spodumene (lithium ore), and fluorite, and as a high-efficiency corrosion inhibitor for ferrous and non-ferrous metals in rust-preventive oils, cutting fluids, and metalworking lubricants. It's also used as a mild surfactant in personal care products and in oilfield, textile, and other industrial applications.
The grades differ mainly in active matter content and free oleic acid limit: Special Grade is ≥94% active matter with ≤6% free oleic acid, Grade 1 is ≥90% active with ≤8% free oleic acid, Grade 2 is ≥85% active with ≤10% free oleic acid, and Grade 3 is ≥80% active with ≤10% free oleic acid. Special Grade is recommended for precision flotation and high-performance corrosion inhibitor formulations, while Grade 3 is a cost-effective option for bulk industrial use.
For precision flotation of tungsten, spodumene, or fluorite ores, Special Grade or Grade 1 are recommended for their higher active matter content and lower free oleic acid. Grade 2 or Grade 3 can suit less demanding flotation circuits where cost is the primary driver. Contact us with your ore type for a specific grade recommendation.
Yes — it has a biodegradable profile, which supports its use in personal care formulations (shampoos, facial cleansers, body wash) as a mild surfactant, as well as in environmentally sensitive industrial applications such as food processing and agrochemical formulation.
For corrosion inhibitor applications, it can be formulated as sodium, potassium, or amine salts for enhanced performance in protecting ferrous and non-ferrous metal surfaces, including in acidic and saline downhole environments for oilfield use.
Standard packaging is 50 kg or 200 kg plastic drums, with IBC totes available for larger orders. Store sealed in a cool, dry place away from moisture and heat — shelf life is a minimum of 24 months under recommended storage conditions.
Pricing depends on grade (Special, Grade 1, 2, or 3), active matter content, salt form (free acid vs. sodium/potassium/amine salts), order quantity, and destination/shipping terms. Contact us with your grade and quantity for a quote.
Yes — a certificate of analysis (COA) confirming active matter content and free oleic acid level, along with a material safety data sheet (MSDS), are available on request with every shipment.
