Description

2-Ethylhexyl 4-Hydroxybenzoate is a synthetic ester derived from 4-hydroxybenzoic acid, widely recognized for its role as a preservative and UV absorber. This compound matters for its ability to inhibit microbial growth and protect formulations from photodegradation, ensuring product stability and shelf life. It is primarily needed by manufacturers in the cosmetics, personal care, and industrial coating sectors seeking effective, broad-spectrum stabilization solutions.

Application

• Primary use as a preservative in cosmetic and personal care formulations such as creams, lotions, and sunscreens.
• Acts as a UV filter/stabilizer in plastics, coatings, and adhesives to prevent yellowing and degradation.
• Used in the stabilization of industrial fluids and lubricants against microbial spoilage.
• Employed as an intermediate in the synthesis of other specialty chemicals and pharmaceutical agents.
• Potential application in food-contact materials and packaging for its preservative properties.
• Utilized in hair care and colorant products to enhance formulation longevity.
