CAS 4247-02-3

Isobutylparaben

Description:

Isobutylparaben, with the CAS number 4247-02-3, is a chemical compound belonging to the paraben family, which are widely used as preservatives in cosmetics, pharmaceuticals, and food products. It is an ester formed from p-hydroxybenzoic acid and isobutanol. Isobutylparaben is characterized by its ability to inhibit the growth of bacteria and fungi, thereby extending the shelf life of products. It is typically a colorless to pale yellow liquid with a mild odor. The compound is soluble in alcohol and oils but has limited solubility in water. Isobutylparaben is known for its low toxicity and is generally recognized as safe when used in appropriate concentrations. However, like other parabens, it has been the subject of scrutiny regarding potential endocrine-disrupting effects, leading to ongoing research into its safety profile. Regulatory agencies have established guidelines for its use, ensuring that it is employed within safe limits in consumer products.

Isobutyl-4-hydroxybenzoate

CAS: 4247-02-3

Isobutyl-4-hydroxybenzoate is a preservative that is used in cosmetics, foods, and pharmaceuticals. It has bacteriostatic activity against Staphylococcus aureus and other bacteria. Isobutyl-4-hydroxybenzoate prevents bacterial growth by binding to the cell wall at an affinity site and inhibits the production of enzymes that are necessary for cell division. Isobutyl-4-hydroxybenzoate also has antibacterial activity against gram positive and gram negative bacteria. This synthetic molecule is not active against acid-fast bacteria such as Mycobacterium tuberculosis or Mycobacterium avium complex.
