About

Ozonized turpentine is produced by reacting turpentine oil with ozone, creating a complex mixture of polar oxidation products including ozonides, aldehydes, and acids. Used as an antimicrobial and oxidizing agent in skin care, though it can be a sensitizer.

Turpentine oil (distilled from Pinus spp. resin) treated with ozone undergoes peroxidation reactions forming a complex mixture: primary ozonides, aldehydes (glycolaldehyde, formaldehyde, acetaldehyde), carboxylic acids (formic, acetic, glycolic), and hydrogen peroxide. These are the 'active' antimicrobial constituents. The ozonide derivatives provide oxidative antimicrobial activity against bacteria and fungi. However, the aldehydes and peroxides are skin sensitizers and irritants. The mixture can be a strong fragrance allergen and may generate free radicals. The variable composition of the ozonization products makes batch-to-batch reproducibility challenging. Restricted under the EU ozone-depleting substances regulation (ozonization precursors may involve chlorine or bromine chemistry).

Function

ANTIMICROBIAL, OXIDISING, SKIN CONDITIONING

Skin benefits

  • Broad-spectrum antimicrobial activity
