Description

Myreth-5 Carboxylic Acid is a high-purity, synthetic carboxylic acid derivative of polyethylene glycol (PEG) ether. This compound serves as a versatile intermediate and functional ingredient, prized for its surfactant properties and ability to modify solubility and surface tension. It is essential for manufacturers in the personal care, pharmaceutical, and specialty chemical industries seeking to formulate advanced emulsions, delivery systems, and performance materials.

Application

• Personal Care & Cosmetics: A key intermediate in the synthesis of PEG ether esters, used as emulsifiers, solubilizers, and mild surfactants in creams, lotions, and cleansers.
• Pharmaceutical Excipients: Employed in the production of non-ionic surfactants and solubilizing agents for drug delivery systems and topical formulations.
• Industrial Surfactants: Acts as a raw material for manufacturing specialty surfactants used in textile processing, agrochemicals, and industrial cleaning.
• Chemical Synthesis: Serves as a versatile building block for creating esters, amides, and other derivatives with tailored hydrophilic-lipophilic balance (HLB).
• Lubricant & Metalworking Additives: Used as an intermediate to produce additives that enhance lubricity, corrosion inhibition, and emulsification.
