Pentyl p-hydroxybenzoate

Description:

Pentyl p-hydroxybenzoate, also known as pentyl paraben, is an ester derived from p-hydroxybenzoic acid and pentanol. It is commonly used as a preservative in cosmetics, pharmaceuticals, and food products due to its antimicrobial properties. This compound typically appears as a colorless to pale yellow liquid with a mild odor. It is soluble in organic solvents such as ethanol and propylene glycol but has limited solubility in water. Pentyl p-hydroxybenzoate exhibits a relatively low toxicity profile, making it a popular choice in formulations. Its effectiveness as a preservative is attributed to its ability to inhibit the growth of bacteria, yeast, and mold, thereby extending the shelf life of products. However, like other parabens, it has faced scrutiny regarding potential endocrine-disrupting effects, leading to ongoing research and regulatory discussions. Overall, pentyl p-hydroxybenzoate is valued for its preservative qualities while also being subject to safety evaluations in consumer products.

n-Pentyl 4-hydroxybenzoate

CAS: 6521-29-5

n-Pentyl 4-hydroxybenzoate is a preservative that inhibits the growth of microorganisms. It is used in products such as cosmetics, pharmaceuticals, and food to prevent spoilage. The antimicrobial activity of n-pentyl 4-hydroxybenzoate has been shown to be due to p-hydroxybenzoic acid, which binds to bacterial cell walls. This binding prevents the formation of an antibiotic-inhibitor complex with the enzyme cell wall synthesis that is required for cell wall biosynthesis, inhibiting protein synthesis and cell division. n-Pentyl 4-hydroxybenzoate has also been shown to inhibit bacterial growth in vitro and in vivo in rats by interfering with protein synthesis in rat liver microsomes.
