Description

Stearic Acid, Compound With 2,2'-Iminodiethanol (1:1) is a specific organic salt formed from stearic acid and diethanolamine. This compound is valued for its dual functionality, combining the hydrophobic, lubricating, and emulsifying properties of a long-chain fatty acid with the hydrophilic, pH-buffering, and metal-chelating characteristics of an alkanolamine. It is primarily utilized by formulators in the personal care, cosmetics, and industrial sectors seeking stable, multifunctional ingredients for emulsion systems, corrosion inhibition, and as processing aids.

Application

• Cosmetic & Personal Care Emulsifier: Acts as a non-ionic emulsifier and opacifying agent in creams, lotions, and hair conditioners.
• Metalworking Fluid Additive: Functions as a corrosion inhibitor and lubricity agent in synthetic and semi-synthetic metalworking fluids.
• Textile Softener & Auxiliary: Used as a softening agent and antistatic component in textile finishing formulations.
• Industrial Surfactant Intermediate: Serves as a key intermediate for the synthesis of more complex quaternary ammonium compounds and other surfactants.
• Polishing & Cleaning Compounds: Incorporated into pastes and compounds for metal and automotive polishing to provide lubricity and shine.
• Pharmaceutical Ointment Base: Can be used as a component in non-aqueous ointment and cream bases for topical drug delivery.

Quality Control

Our Stearic Acid, Compound With 2,2'-Iminodiethanol (1:1) is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. While available in standard technical grade, production can be aligned with cGMP principles for sensitive applications. A detailed Certificate of Analysis (COA) documenting key parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking or hydrolysis.
