BENZYL BENZOYLOXYBENZOATE.

Valuable CAS 96682-10-9 / FRAGRANCE

A sophisticated multi-functional ester that serves as both a high-performance fragrance fixative and a targeted antimicrobial agent. It is prized in precision skincare for its ability to stabilize volatile compounds while providing secondary benefits for skin structure maintenance.

Antimicrobial Fragrance Fixative MMP Inhibitor Perfuming

Science

This ingredient primarily inhibits the proliferation of odor-producing bacteria such as Corynebacterium by disrupting their metabolic environment. Additionally, emerging research suggests it may function as a matrix metalloproteinase (MMP) inhibitor, potentially shielding the dermal matrix from enzymatic degradation of collagen and elastin fibers.

Key findings

  1. 01 Clinical evaluation demonstrates significant antibacterial longevity against malodor bacteria compared to conventional deodorant actives at concentrations of 0.1-5.0%.
  2. 02 Patent literature identifies the molecule as a potential inhibitor of collagen-degrading enzymes (MMPs) at usage levels between 0.01-3.0%.

Because it often appears as a fragrance fixative or ancillary antibacterial, it is frequently used at trace levels (below 0.1%) where it provides scent stability but fails to reach the concentration required for measurable anti-aging or therapeutic antimicrobial effects.
