I. Introduction
Unilong is a professional manufacturer and supplier of specialty chemicals, offering high-purity N-Oleoylsarcosine (CAS 110-25-8) —a multifunctional anionic surfactant that combines mild cleansing properties with effective antimicrobial activity and metal corrosion inhibition. Designed for formulators and industrial engineers, this versatile ingredient serves as a reliable solution for both personal care and metalworking applications, with quality standards comparable to leading international brands.
II. Product Overview
N-Oleoylsarcosine (CAS: 110-25-8) is an amino acid-based surfactant derived from sarcosine and oleic acid. It appears as a transparent yellow to brown viscous liquid at room temperature, with a characteristic mild fatty odor. Its molecular structure features both hydrophilic (carboxylate group from sarcosine) and hydrophobic (C18:1 unsaturated long chain from oleic acid) moieties, enabling it to function effectively across aqueous and oil-based systems.
As a member of the N-acylamino acid family, this surfactant offers unique interfacial properties that distinguish it from conventional petrochemical-based surfactants. Unilong offers this product in two purity grades to meet varying formulation requirements across different industries.
III. Key Features & Applications
For Personal Care Formulators: A Mild, Antimicrobial Cleansing Agent
1. Superior Mildness for Sensitive Formulations
N-Oleoylsarcosine exhibits significantly lower skin and eye irritation potential compared to conventional anionic surfactants such as sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES). This superior mildness profile is attributed to its amino acid-based structure, which closely resembles the skin’s natural moisturizing factors. This makes it particularly suitable for:
(1) Facial cleansers and makeup removers: Provides effective cleansing without stripping the skin’s natural barrier; ideal for daily-use products
(2) Baby care products: Meets the stringent safety requirements for infant and children’s formulations
(3) Sensitive skin formulations: Reduces the risk of stinging, redness, and allergic reactions
(4) Oral care products (toothpastes, mouthwashes): Used in toothpastes and mouthwashes for its cleansing and antimicrobial benefits
(5) Intimate hygiene products: Offers gentle cleansing for delicate areas
2. Inherent Antimicrobial Activity
The compound demonstrates natural antimicrobial and virucidal properties, helping to preserve formulation integrity while potentially reducing reliance on traditional preservative systems—an advantage for “clean label” and mild formulation concepts.
3. Foam Quality & Sensory Profile
It generates rich, fine-textured foam with good stability and easy rinseability. Formulations containing N-Oleoylsarcosine leave skin feeling clean without tightness or dryness, enhancing the consumer sensory experience.
4. Compatibility & Formulation Tips
Compatible with other amino acid surfactants, betaines, and non-ionics
(1)For aqueous systems, pre-neutralization with organic bases (e.g., triethanolamine, AMP-95) is recommended
(2)Ideal for synergistic blends that reduce overall surfactant irritation potential
For Metalworking & Industrial Applications: An Efficient Corrosion Inhibitor
1. Effective Rust Prevention at Low Dosages
N-Oleoylsarcosine functions as an effective corrosion inhibitor through adsorption onto metal surfaces. Its polar carboxylate group forms a strong bond with the metal substrate, while the long hydrophobic oleoyl chain creates a dense, water-repellent monomolecular layer. This protective barrier effectively prevents moisture, oxygen, and corrosive electrolytes from reaching the metal surface.
2. Applications in Industrial Formulations
(1) Rust preventive oils and greases
(2) Metalworking fluids (cutting, grinding, rolling)
(3) Temporary corrosion protection coatings
(4) Industrial cleaners for metal parts
3. High Thermal Stability
With a decomposition temperature exceeding >220℃, this surfactant maintains stability under high-temperature processing conditions—an advantage over conventional rust inhibitors in demanding metalworking environments.
4. Broad Compatibility
N-Oleoylsarcosine demonstrates good solubility in mineral oils, synthetic esters, and organic solvents, and remains compatible with commonly used additives in industrial lubricant and fluid formulations.
