98% N-Oleoyl Sarcosine CAS 110-25-8

 What is N-Oleoylsarcosine?

N-Oleoylsarcosine, commonly known as oleoylsarcosine, is also called N-oleoylsarcosine, N-oleoyl-N-methylglycine, or oleoylsarcosine salt. Its English alternative names include Oleoyl Sarcosine, N-Oleoyl-N-methylglycine, and Sarkosyl O. It is a compound derived from the condensation of oleic acid and sarcosine (N-methylglycine). Its chemical formula is usually written as:

C21H39NO3

Molecular weight approximately 353.54, CAS number 110-25-8.

It is generally a pale yellow to amber-colored viscous liquid or waxy substance, oil-soluble, and possesses both hydrophilic carboxyl and amide groups, making it a typical amino acid-type anionic surfactant. Its molecule has a hydrophobic long-chain olefin (oleic acid chain) at one end and a hydrophilic sarcosine group at the other. This amphiphilic structure endows it with multiple surface activities, including wetting, emulsification, dispersion, and complexation, and it forms an adsorbed film on metal surfaces, playing a role in corrosion inhibition and rust prevention—this is its most prominent value in the industrial field.

From a chemical classification perspective, oleylsarcosine belongs to the amino acid-type surfactant class and is a sarcosinate derivative. It is derived from naturally occurring fatty acids and amino acids and has characteristics such as resistance to hard water, low toxicity, and easy biodegradability.

In terms of chemical classification, oleylsarcosine belongs to the amino acid-type surfactant family and is a sarcosinate derivative. It is prepared from natural fatty acids and amino acids . It has properties such as hard water resistance, low toxicity and easy biodegradability.

Industrial grade oleoyl sarcosine refers to oleoyl sarcosine products for industrial production. The quality-control emphasis is different from that of reagent-grade products.

The industrial oleoyl sarcosine is characterized by the following indicators:

1. Main content

Industrial applications place greater emphasis on the stability of the content of active ingredients, such as the content of oleylsarcosine (common specifications ≥98%), and the content of byproducts such as free fatty acids and free sarcosine. These indicators directly affect rust prevention performance and surface activity.

2. Acid value

Acid value is an important indicator for measuring the carboxyl group content in carboxylic acid surfactants. It directly affects the dosage of neutralization and saponification formulations, as well as the performance of rust prevention. It is a key focus for industrial customers.

3. Color and appearance

Industrial customers typically require products to be uniform, viscous liquids or waxes ranging from pale yellow to amber in color; abnormal color often indicates oxidation or contamination by impurities.

 What are the applications of industrial-grade N-Oleoylsarcosine?

The core value of industrial-grade oleoyl sarcosine lies in its excellent metal corrosion and rust inhibition properties, as well as its surface activity that combines wetting, emulsifying, and dispersing properties. The following are its main applications in the industrial field.

1. Rust prevention and corrosion inhibition of metals

Oleylsarcosine is a key ingredient in corrosion inhibitors and antirust additives used in antirust oils, antirust liquids, temporary antirust coatings, and vapor phase corrosion inhibitor (VCI) packaging materials. Its carboxyl and amide groups can form an adsorption film on the metal surface, which can provide good rust protection for ferrous metals such as steel and iron and non-ferrous metals such as copper and aluminum.

2.Metalworking fluid

Oleoyl sarcosine is a corrosion inhibitor and emulsifier in metalworking fluids, e.g. in cutting and grinding fluids, where it helps to create a stable emulsion system and protect the workpiece and machine tool against corrosion.

3.Lubricating oil and grease additives

Oleylsarcosine can be used as a rust and corrosion inhibitor in engine oil, hydraulic oil, gear oil and grease to lubricate and increase metal protection and equipment life.

4.Industrial cleaning agents and surfactants

Oleoyl sarcosine is used in formulations of industrial cleaning agents, metal surface treatment agents and other products for its excellent wetting, emulsifying, dispersing and hard water resistance properties, to help remove oil stains and protect metal surfaces.

5. Fuel and oilfield related applications

Oleylsarcosine can be used as a corrosion inhibitor in fuel oil, refrigeration oil and other systems, and can also be used in oilfield-related rust and corrosion inhibitor formulations to help inhibit metal corrosion during oil storage, transportation and extraction.

6. Mineral flotation collectors

In the field of mineral processing, oleoylsarcosine compounds can be used as collectors or auxiliary collectors in the flotation research and application of partially oxidized ores and rare metal ores, utilizing their adsorption effect on the mineral surface to improve the separation effect.

7. Raw materials for daily chemical and personal care products

As a mild amino acid-based surfactant, oleoylsarcosine can be used in daily chemical formulations such as washing and care products and cleaning products. It has both cleaning and corrosion-inhibiting properties and can also be used for rust prevention and protection of metal packaging containers.

Summarize

N-Oleoylsarcosine, or oleoylsarcosine, is an amino acid-type anionic surfactant derived from oleic acid and sarcosine, possessing excellent amphiphilic structure and metal adsorption capacity. Industrial-grade oleoylsarcosine, due to its combined corrosion inhibition, rust prevention, wetting, emulsification, and dispersion surface activities, is widely used in rust-preventive oils and vapor phase rust-preventive packaging, metalworking fluids, lubricant additives, industrial cleaning agents, fuel additives, mineral flotation, and daily chemical raw materials. While ordinary consumers do not directly come into contact with the pure product, it may be relevant to everyday items such as rust-preventive packaging paper for hardware, automotive lubricants, and processed metal products
