2-Phenoxyethanol CAS#122-99-6

2-Phenoxyethanol, also known as ethylene glycol phenyl ether, is a widely used ingredient in the cosmetics and pharmaceutical industries, primarily recognized for its preservative properties. With the chemical formula C8H10O2, this organic compound is effective in preventing microbial growth, ensuring the safety and stability of formulations.

As a para-hydroxybenzoate (parabens alternative), 2-phenoxyethanol is appreciated for its broad-spectrum antimicrobial activity, which includes the inhibition of both gram-positive and gram-negative bacteria, as well as yeast and mold. It is commonly used in concentrations ranging from 0.5% to 2% to provide adequate preservation without impacting the product’s sensory profile.

This colorless liquid is soluble in water and most organic solvents, making it compatible with a variety of formulations. Its low order of toxicity and minimal skin irritation potential at prescribed concentrations contribute to its favorable safety profile.

In summary, 2-phenoxyethanol is a reliable and efficient preservative for a diverse range of cosmetic products, offering broad-spectrum protection against microbial contamination while maintaining product integrity and consumer safety. Its use is critical in upholding the quality and longevity of personal care products.
