Aluminum Zirconium Trichlorohydrex Gly

What is Aluminum Zirconium Trichlorohydrex Gly?

Aluminum Zirconium Trichlorohydrex Gly is a synthetic coordination complex derived from aluminum, zirconium, chloride, and glycine, primarily employed in underarm and body antiperspirant formulations. This ingredient functions by hydrolyzing upon application to the skin, where it reacts with electrolytes in sweat to form a temporary gel-like plug within eccrine sweat ducts. This mechanism reduces perspiration flow without fully blocking it. Additionally, its astringent nature causes mild contraction of surface skin proteins, offering a refined, less oily appearance. As a deodorant component, it helps limit bacterial growth in moist areas by altering the skin's environment, curbing odor production. Typically found in stick, roll-on, or spray deodorants, it provides extended protection during daily activities.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Antiperspirant

Reduces perspiration by temporarily plugging sweat ducts (commonly with aluminum salts), decreasing wetness in underarm and body antiperspirant products.

Astringent

Creates a temporary tightening and toning effect by contracting surface proteins, helping reduce the look of oiliness and refining feel on skin.

Deodorant agent

Targets malodor by neutralizing odor molecules, inhibiting odor-causing microbes, or adding fragrance notes to improve underarm and body freshness.

Deodorant

Helps control body odor by reducing odor-causing bacteria and/or neutralizing or masking malodor, without necessarily reducing sweat production.

Benefits

Helps reduce underarm and body wetness by forming temporary plugs in sweat ducts.

Offers a tightening effect on skin for a smoother, less oily feel.

Supports odor control by limiting bacterial activity in sweat-prone areas.
