What is Zinc Phenolsulfonate?

Zinc phenolsulfonate is a coordination complex formed from zinc ions and phenolsulfonic acid, a synthetic organic compound. It belongs to the category of antimicrobial and astringent agents commonly found in deodorants and body care products. In formulations, it works by releasing zinc ions that interfere with bacterial enzymes and cell membranes, limiting the proliferation of microbes responsible for odor generation on the skin. Its astringent properties arise from protein contraction on the skin surface, providing a tightening sensation that minimizes the shiny appearance of perspiration-prone areas. As a multifunctional ingredient, it also aids in preserving product integrity against microbial contamination. This dual action supports odor neutralization and fresher skin sensation in underarm and body applications, typically integrated at effective levels for daily use.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Astringent
Creates a temporary tightening and toning effect by contracting surface proteins, helping reduce the look of oiliness and refining feel on skin.
Biocide
Destroys or inhibits harmful organisms to preserve products.
Deodorant agent
Targets malodor by neutralizing odor molecules, inhibiting odor-causing microbes, or adding fragrance notes to improve underarm and body freshness.
Antimicrobial agent
Helps limit growth of bacteria and other microbes on skin or in the formula; may be used for product protection, odor control, or targeted antimicrobial effects.
Deodorant
Helps control body odor by reducing odor-causing bacteria and/or neutralizing or masking malodor, without necessarily reducing sweat production.
