Description

Myreth-5 Carboxylic Acid is a high-purity, synthetic carboxylic acid derivative of the myreth series, serving as a key intermediate and functional ingredient in advanced formulations. Its value lies in its ability to act as a versatile building block for emulsifiers, surfactants, and specialty esters, offering formulators precise control over product performance. This compound is essential for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking to develop stable, high-quality emulsions and delivery systems.

Application

• Personal Care & Cosmetics: A vital raw material for synthesizing mild, non-ionic surfactants and emulsifiers used in facial cleansers, shampoos, lotions, and creams.
• Pharmaceutical Excipients: Employed in the production of specialized esters that function as solubilizers, penetration enhancers, or emulsion stabilizers in topical and transdermal drug delivery systems.
• Industrial Surfactants: Acts as a precursor for manufacturing industrial-grade emulsifiers and wetting agents used in agrochemicals, textile processing, and metalworking fluids.
• Polymer & Resin Modification: Used as a reactive intermediate to introduce carboxyl functionality, modifying the properties of polymers for coatings, adhesives, and specialty plastics.
• Lubricant & Grease Additives: Serves as a chemical intermediate for creating synthetic esters that enhance the performance and stability of high-end lubricants.
